How to hem a roof eaves. How to arrange reliable and beautiful roof overhangs Sheathing the eaves of a house with plastic lining

Regardless of the finishing material of the hem, work on the roof begins with the hem, and not with the tiles, as many people think and do.
After installing the rafters and trimming them around the perimeter. a rough frontal board and sheathing are filled in under the finishing material of the hem.
The hemming can be done from anything, but when you are planning an insulated roof, you need to approach the finishing material “thoughtfully” so that later it will not be excruciatingly painful for wasted money.
What overhang should I leave?
According to the Standard, at least 50 cm clean. This is the bare minimum. In this case, it is necessary to take into account whether external insulation of the walls and their cladding will be done; if so, then extend the overhangs to accommodate this thickening of the wall.
The higher the house, the larger the overhang should be, because its direct purpose is to protect the walls, windows and foundation from water. In addition, the larger the overhang, the more respectable the house looks.
How to finish the overhangs?
Anything, even a rough board, if you don’t care how it will look and function.
If you take this seriously, you will notice that for these purposes there is a specialized material called Soffit. Made from vinyl, which behaves well at sub-zero and plus temperatures. The panels come with different stripes, such as J, F, chamfer, finishing.
For overhangs, many components are not required; all their variety is intended mainly for covering the walls of a house - with siding. Siding and soffit are the same material.
You can hem it with a board, which many people do.
There are restrictions on board hemming for warm roofs.
Anyone who is already familiar with warm roofs (attic) knows that the under-roof space must be ventilated, and for this there must be access to air. If you decide to hem it with a board, then you will need to put a lot of gratings in a horizontal plane or drill a lot of holes in the boards - choose for yourself.
Some people line it with plastic panels to reduce the cost, I don’t know how much cheaper it is, but I know for sure that it is not intended for external work. Plastic does not tolerate low temperatures and is not protected from exposure to UV rays, and therefore collapses.
You can perform a combined hemming - put it on the front finishing board, and hem it underneath with a perforated soffit - and “the wolves are fed and the sheep are safe.” This is if the house is wooden and the same hemming is required. Soffits come in different colors and can be matched to any home decor.
There are many complaints about the rotating chamfer. We all know that materials expand in heat and vinyl is no exception. To smooth out this wave, there is a finishing or final or final stripe - these are all the same thing, different names are to confuse us.
There is an option - order the chamfer from metal and this is a good option, especially if the hem is brown and they don’t produce a brown chamfer. I’ll say right away that it’s not difficult to find a brown bevel, because any niche in the market is quickly filled and some manufacturers produce the bevel. BUT! I categorically do not recommend buying it, because it fades in the sun in a couple of years, and then looks like disgusting whitish stripes.

This is not Happy End.
And, to be continued.


After completing the construction of the roofing structure and the installation of the covering, it is time to file the roof overhangs, which are sometimes simply called the frame. The appearance of the entire building depends on the method of filing and choice of material. The box under the roof is the final touch that gives the entire structure a finished look.

The design of the box also includes elements of the ventilation system of the under-roof space. Don't forget about fixing the gutters.

To hem overhangs, you can use a variety of materials and a variety of designs.

What is a roof overhang?

An overhang is a structure protruding a certain length beyond the line of the load-bearing walls of a building, the main function of which is to protect the building and its load-bearing structures from snow, rain, and melt water flowing down the roof.

The length of the overhangs is on average 500 - 600 cm, but it can be increased if desired.

Usually, overhangs are created using the rafter system, but sometimes it is not possible to create such overhangs as a continuation of the rafters. In such cases, the so-called forced continuation of the rafter structure is used. The elements forming the elongated rafters are called “fillies”.

Since the gable of a building is also an unprotected part of the house or roof, it also needs protection from the destructive effects of rain and snow. The width of the front overhangs should be 500 mm or more, and such a structure is constructed using cornice-type boards.

The bottom of the overhangs must be sheathed to extend the service life and improve the exterior of the building.

What technologies are used and what to focus on when filing overhangs?

You should start filing when the work on installing the rafters is completely completed and you need to move on to laying the sheathing along the border of the roof covering.

When covering overhangs, several important points must be taken into account.

  • Before starting work, it is necessary to saw off the ends of the rafters exactly along the same line. The parallelism of this line relative to the adjacent wall of the building must be maintained.
  • In most cases, sheathing is done with boards. Its visual appeal depends on maintaining equal width in different sections of the wall.
  • The ends of the rafters are sawed off vertically, while the end part is sewn up in the same way as the entire hem.
  • After sawing the rafters is completed, the first sheathing board is placed along it in one straight line. In the future, it serves as a guide for completing the rest of the work.
  • One important point must be taken into account: you can begin external insulation only after completing the process of filing the roof overhangs.
  • If insulation is done before installing the sheathing, boards will have to be torn off to install high-quality insulation.

Selecting material for cladding overhangs

There are a lot of materials that are designed for lining roof overhangs. Despite their diversity, they are subject to the same requirements.

The material for the lining must provide reliable protection of the eaves of the roof from any precipitation, its insulation, as well as good ventilation of the under-roof space. High-quality lining material retains its original characteristics for a long time.

The most commonly used materials for lining overhangs

  • Corrugated sheet

It consists of galvanized steel sheets coated with a polymer layer. The polymer is applied mainly for additional protection of galvanized steel, but also performs an indirect function - it provides a variety of colors.

Thanks to galvanized steel, a high level of rigidity of the sheets and resistance of their geometric parameters in relation to thermal and mechanical loads is achieved. The former includes exposure to high temperatures, and the latter – wind pressure.

When choosing corrugated sheeting for lining overhangs, ventilation is ensured due to the presence of a gap that is created by the height of the wave. Panels from corrugated sheeting can be made to the required width, which significantly reduces the time required for their installation, as well as the financial costs of lining.

  • Soffits

These are plastic-based panels that are produced specifically for lining roof overhangs. The soffit is very easy to use and therefore very popular. In many ways it is similar to siding, but it also has some differences.

Firstly, the thickness of the soffit plastic is much greater; secondly, the material has a special perforation, the purpose of which is to ventilate the under-roof space. Thirdly, the soffit plastic contains special UV stabilizers, which significantly increase its resistance to ultraviolet radiation.

Soffits are very lightweight, making them easy to transport. To install the spotlights, you do not need any special equipment, which allows you to cope with the work yourself, without the help of professional builders.

Since the spotlights are resistant to adverse weather conditions and sudden temperature fluctuations, they can be used at any time of the year and in any weather conditions.

A wide selection of colors allows you to implement the most original design solutions.

Soffit panels are cut to the length of the overhangs. They are installed not along the wall, but perpendicular to it.

  • Ordinary wooden lining

Since, when used as a lining, the material is used outdoors and is exposed to adverse environmental factors, when choosing it, you must be especially careful about the quality of the wood.

Attention should be paid to such qualities as the thickness of the product (it should not be too thin), the degree of humidity (the lining should not be too dry or too wet).


The finished lining strips are laid very tightly together. In order to ensure ventilation, it is necessary to cut ventilation grilles into the structure every 1.5 meters.

Planed edged boards are the most cost-effective option. Its thickness should be from 17 to 22 mm, the width is selected individually and can range from 50 to 250 mm.

The wood used is from coniferous trees: spruce, pine, larch. Before installation, the boards must be impregnated with antiseptic and waterproof (impregnation, paint, varnish) compounds.

As in the case of using lining, the moisture content of the boards should correspond to the natural humidity of the environment. If you use wood that is too dry or too wet, it will warp over time.

Overhang trim boards are placed parallel to the wall or perpendicular to it. As a rule, a gap of 10-15 mm is maintained between them so that air masses can freely penetrate into the under-roof space and ensure its uniform ventilation.

When positioned perpendicularly, the plank lining is attached on both sides; when positioned parallel, it is attached every meter. If the overhang is wide, then the fastening is made in the middle.

  • PVC siding

One of the most economical and technologically advanced materials for hemming. Moisture-resistant material is used for overhangs. The kit includes strips intended for covering the edges (in the shape of the letter “P”), corners for fastening planks and joints, and ventilation grilles.

The filing is positioned perpendicular to the wall, since this is much more convenient and economical, taking into account the fact that the siding does not have a sufficient degree of rigidity and may often need to be secured. Cut strips of the required length in 2-4 places are attached to a wooden frame. The number of attachment points depends on the width of the overhangs.

  • Sheet metal

Steel with a polymer coating, galvanized, copper, aluminum allows you to quickly complete the cladding. The thickness of the metal sheet should be 0.6-0.8 mm.

The length of the sheets can reach 6 m, and their width must correspond to the size of the overhang.

Holes for ventilation are cut into the sheets or perforated sections are inserted during installation.

If the sheets are steel, then the cutting areas must be treated with an anti-corrosion agent or coated with paint. Aluminum and copper do not need to be processed.

When working with metal filing, you must have special equipment for cutting the material.

  • Wood boards

The advantage of this material is that it is easy to cut. The slabs are available in a waterproof version. Their installation is carried out in large planes by attaching them to wooden beams with screws.

When using wood boards, ventilation holes with grilles will need to be cut into them and covered with paint to give the overhangs an attractive appearance. The rigidity of the boards is quite high. For OSB, 6.3 mm will be enough. The material is attached to the wooden frame every 1-1.2 m.

Some features of installation of the filing and frame for it

As already mentioned, after installing the roof structure, you need to move on to covering the overhangs. There are two main methods of filing.


With the first method, it is carried out directly along the rafters. This option is suitable for roofs with a slight slope or when there is a need to increase the height of the building.

With this method, the lower part of the rafters is located in a single plane. If this condition is not met, then a flat plane can be achieved by using additional boards: they should be overlapped on the rafters.

Then you need to align and screw the first and last strips of sheathing material, then tighten the threads to maintain the level and attach the remaining strips.

When roofing boards converge on both sides, rafter boards are installed on both sides. The usual length of overhangs is 600 mm.

The second method is more popular. All rafters should be trimmed horizontally and vertically. A board is fixed at the bottom of the rafters, and a beam is attached to the wall. It is located 1 cm above the frontal board in order to allow moisture to drain away.

If the overhang width is more than 450 mm, an additional board should be installed in the middle. When the roof slopes converge in one place, the board must be nailed from the corner of the roof to the corner of the building.

Regardless of the cladding method, the roof overhang box is installed in the same way: along the length of the wall along the gable, a board is stuffed onto the sheathing, from which the distance corresponding to the length of the overhangs is measured, after which the board is nailed parallel to the gable wall.

The result is a rigid structure independent of the wall. We must ensure that all fastenings are reliable - with screws, or better yet, with metal plates and corners.

After completing the installation of the frame, you need to start covering.

Cladding with clapboard or board

Since wind, rain, snow, cold air, etc. will penetrate into this place, the fastenings of the overhang sheathing must be very reliable.

The best choice is fastening with screws.

You must use at least two screws at each mounting point.

Along the length of the boards, they are joined in a checkerboard pattern to prevent two joints from being located next to each other. The exception is corners where sawing is done at an angle of 45 degrees (in some cases at a different angle).

The board or lining is treated on both sides with an antiseptic. The composition is applied twice: the first time before installation (both surfaces and ends are treated), and the second time after installation. In this case, it is necessary to cover all fasteners, cutting points, etc. with the composition.

To complete the work, ventilation grilles must be installed. When using linings, they are cut into the box. It's better to do this in advance.

How to install corrugated sheeting?

The filing of overhangs made of this material is carried out in the following sequence:

  • Sheets of corrugated sheets are screwed along the cornice and wall to the frame, using self-tapping screws;
  • At the junction points of the wall and the material, a frontal strip, as well as an internal corner, are mounted. The frontal strip is screwed to the frontal board, and the inner corner is screwed to the corrugated sheet;
  • The outer corner is fastened at the points of external joints of the profiled sheets;
  • Profiled sheets are screwed along the pediment along the outer edge of the overhangs and along the wall;
  • After this, the corners and end strip are fastened;
  • To facilitate the installation process and ensure ventilation, the width of the profiled sheets should be 2 cm less than the width of the overhangs.

Fitting overhangs with soffits

One of the obvious advantages of spotlights is the ease of installation. Even beginners can do it.

Finishing overhangs using soffits consists of the following steps:

  • the hemming parts are cut so that their length matches the width of the overhangs;
  • wooden strips are attached to the roof overhangs;
  • an F- or J-profile is screwed to the bottom of the bar, which should act as a groove;
  • one edge of the soffit panel is inserted into the groove, and the other is screwed to the rafter beam;
  • The side screwed to the rafter beam is covered with an L-profile (front strip).

CONCLUSIONS

  • The main purpose of overhangs is to protect the building from precipitation and melt water.
  • Finishing the overhangs is the final stage of roof installation.
  • Sheathing overhangs can be done in two ways.
  • Materials for filing must provide protection from precipitation, insulation, and ventilation of the under-roof space.
  • The most common materials for cladding are corrugated sheets, siding, soffits, wooden lining, edged planed boards, metal sheets, and wood boards.
  • The installation of each cladding material has its own characteristics.

Video instructions on how to properly decorate a roof overhang with soffits

When the installation of the roof covering is completed, work begins on sheathing the roof overhang. This is done not only to protect the facade and provide roof ventilation, but also to give the building a finished appearance. The article will talk about what materials are used for these purposes and how to line the roof eaves with your own hands using soffit, corrugated sheeting and wooden lining.

Roof cornice installation

The eaves overhang is the projection of the rafters beyond the facade of the house. It can be either simple or with take-out. The first one is simpler to implement, and in a strong wind it will not hum unpleasantly, which cannot be said about the second option.

Roof overhang assembly

1- Gutter;

2- drip;

3- metal apron on the front board;

4- self-tapping screw;

6- block 5x5 cm;

7- rafter leg (filly);

8- hemming material;

9- break;

10- boards that form the basis of the eaves overhang;

11-support block for fixing the break.

There are two types of eaves overhang - side and front.

Front roof eaves

The front one is needed to protect the facade of the house. It represents the side edges of the inclined roof slopes. Accordingly, they are absent on a hip (hipped) roof.

The installation of the front overhang of an ordinary gable roof is carried out by releasing load-bearing crossbars attached to the rafters. It is often possible to find that the front cornice is formed by sheathing boards, which are laid on a vapor barrier under the roofing material. A cornice board is attached to them, which will later be sheathed with corrugated board or soffit.

Side roof cornice

All sloping roofs have a side overhang. It is formed by rafters that protrude beyond the walls of the house. The distance of their protrusion is calculated from the height of the house and the width of the blind area, often about 50-70 cm.

Although it is believed that the minimum acceptable overhang size is 50 cm, narrower ones are also found.

  • In this case, the wall of the house must have good wind protection, since it will get very wet under slanting rain.
  • The second option to correct the situation is to install fillies, thereby increasing the length of the rafters. But this is a rather labor-intensive process, and with the roof already done, few people want to open everything up and redo it all over again. Therefore, it is important to provide for the required size of the roof overhang at the construction stage.

The rafters are connected to each other by boards along the entire length of the cornice. In the future, they will be covered with facing material.

Creating proper roof ventilation through eaves

The main function of any eaves is to protect the roof from atmospheric influences. But at the same time, it should not interfere with the natural ventilation of the under-roof space. This is important not only for residential attic floors, but also for cold roofs. Warmer air rising from the ground should pass unhindered through the eaves and, moving between the vapor barrier and roofing material, escape through the ridge to the outside. It is for this reason that when filing the cornice it is prohibited to use various sealants and mounting foams. Otherwise, condensation will form, which will lead to wet roofing insulation.

But there are exceptions here - the eaves are made ventilated only under the roof slopes, and all front overhangs are closed “tightly”.

Selecting materials for roof overhangs

Today there is a wide range of materials for filing roofing eaves. Of course, each of them has its own advantages and disadvantages, but they all fully protect it from moisture and provide insulation and ventilation of the roof. When making a choice in favor of a particular material, you should be guided not only by its beautiful appearance, but also by the length of its service life.

Corrugated sheet

This is galvanized steel with a multi-colored polymer coating. It is resistant to mechanical damage and temperature changes, has the necessary rigidity, and is also not afraid of wind loads. To ensure the necessary ventilation, a gap is made between the corrugated sheeting and the wall of the house equal to the height of its wave.

Soffits

This is the most popular material, specifically designed for hemming cornices. Essentially, these are plastic panels that look like siding, but already have ventilation holes. They also differ from conventional siding in that they contain UV stabilizers that protect soffits from the negative effects of sunlight.

Copper soffits

This is a durable material, very aesthetic and presentable in appearance, but also quite expensive. Copper soffits have high fire-resistant and strength characteristics.

Aluminum soffits

They are very light, fire-resistant, elastic, and if necessary, repairing them is not difficult. They also have high paint fastness, so the color saturation does not change under the influence of ultraviolet radiation.

The only drawback is the scarcity of colors - they are produced in white or brown.

Galvanized soffits

They are durable and do not require additional care. These are durable soffits that are not afraid of moisture and fire. But they have quite a lot of weight, which to some extent makes their installation more labor-intensive.

Vinyl soffits

This is an inexpensive and most popular option for soffits for lining roofing eaves. They are light in weight, perfectly protect against environmental influences, have a noble appearance, are easy to install, and also create a seamless fabric, providing complete ventilation of the under-roof space.

Today they are made of fire-resistant plastic, which is also capable of withstanding heavy loads. Available in three types:

  • solid three-way without ventilated holes;
  • fully perforated;
  • three-lane with a perforated central stripe (the most popular).

Regardless of the chosen soffit material, they are all quite easy to install, and such work will not be difficult even for a beginner in construction. The basic rule when installing them is that they are located perpendicular to the wall, and not along.

Wooden lining and edged boards

It is still often possible to find that real wood is chosen for lining the eaves overhang. Since it is installed outside the house and is exposed to aggressive environmental influences, the choice of material must be approached responsibly. You cannot save money and buy too thin lining; its optimal thickness is 2 cm. It should also be of medium humidity (too wet is not suitable, as it can “sink”, but very dry is also not the best option).

To ensure ventilation, the boards are nailed at a distance of 2 cm from the wall.

Hemming the roof overhang along the rafters

This method is rational for roofs with a slight angle of inclination. The difficulty of this type of cladding is that all the edges of the rafters form an even plane.

But this can be achieved forever, then the way out will be small boards that are attached to the rafters. Their length is equal to the distance from the wall of the house to the edge of the overhang. To install them evenly, first, one board is screwed on each edge of the cornice and twine is stretched between them. All other sections of boards are attached according to the resulting guideline. The sheathing is attached to such a frame using metal corners or screws.

Lining the roof overhang on a wooden frame

This method is ideal for roofs with a large slope. To construct such a box, take a 4 cm thick edged board and attach it between the wall of the house and the edge of the rafters. If one of its edges is installed directly to the rafter leg, then to fix the second edge you will need to install a board adjacent to the wall, which is screwed to the rafters from above.

A second option is also possible, when instead of an additional vertical board, a beam is attached to the wall of the house with dowels.

At this point, the frame of the box is complete, and the sheathing can be attached to it. To ensure the necessary rigidity of the entire structure, everything should be secured not with nails, but with screws or corners.

Fitting eaves overhangs with soffits

Stages of work:

  • The soffits are equipped with two special strips, which have the shape of the letter J or F. One of them is attached to a wooden strip prepared on the wall of the house, and the second is attached to the overhang side. Self-tapping screws are used as fastenings. All planks must be attached absolutely evenly in relation to each other, so it is recommended that you first make markings.
  • Then the width of the roof eaves is measured and 6 mm is subtracted from the result obtained. This is done in order to create the necessary gap that compensates for the thermal expansion of the material. The soffits are cut into strips of the required length.
  • The prepared plates are slightly bent and inserted into the grooves of the installed profiles. Where they are fixed with self-tapping screws.

  • In order to hem the corner of the cornice, the length of the soffit strips must be gradually reduced by cutting off one of the sides at an angle of 45 degrees.

To connect them, an H-profile or two J-profiles are used.

More detailed instructions on how to line the roof eaves with soffits can be viewed in the video below.

Important points when working with spotlights

  • The soffit is attached only at right angles and through special holes;
  • there must be a gap so that the panel can expand or contract freely;
  • optimal size of fastenings: leg length 3 mm, head width 8 mm. They should not be screwed tightly, but have a gap between the head and the surface of the soffit equal to 1 mm;
  • the distance between the fastening points is 40 cm (more often);
  • cut the soffits using a circular saw with a blade on which the teeth are located in the opposite direction. You can also use metal scissors or a knife. In the latter case, it is best to use it to mark the place of the cut, and bending the panel along it, break off the required segment;
  • Soffits should be stored and transported on a flat surface in low stacks (packs of 10-15);
  • despite the fact that the manufacturer assures that it is possible to install spotlights even in winter, it is not recommended to carry out work if the temperature is below 15 degrees.

Lining roof eaves with corrugated sheeting

  • First, a block is nailed to the wall in a horizontal position at the level of the edge of the overhang. At the same level with it, a second block is attached along the edge of the rafter legs;
  • the corrugated sheet is cut to the required length (not forgetting the thermal reserve of the material and the need for a ventilation gap) and attached to the installed bars with self-tapping screws;
  • the junction of the corrugated sheet and the wall is covered with an internal corner strip, and the connection of the outer edge with the rafters is decorated with a similar external corner strip.

At this point, the installation of corrugated board is completed.

Lining the roof overhang with wooden clapboard or board

It is most convenient to file roof overhangs from below, standing on scaffolding or on a stepladder.

Important! The cornice should be hemmed only after the walls of the house are completely insulated from the outside, a vapor barrier has been made and the installation of the facing material has been completed.

Before covering the eaves with clapboard, all rafters on the side eaves must not only be the same length, but also be exactly parallel to the wall of the house. Wind strapping boards are attached to them.

When all this is done, installation of the sheathing fastening begins.

  • First, one board is screwed vertically to the wall, its lower edge should be at the level of the edge of the rafters - in the figure above (1).
  • The second board is attached between the rafters and board number 1 along their lower edges (2). It should be parallel to the ground. Thus, a base is obtained on which the sheathing will be installed.
  • When the frame is prepared, the installation of the sheathing itself begins.
    • When covering the roof eaves with boards, a small gap must be left between them and the wall. The boards themselves are chosen to be smooth, of good quality and 1-2 cm thick.
    • To ensure the necessary ventilation of the under-roof space when covering with wooden lining, it is recommended to install ventilation grilles along the entire perimeter in increments of 1.5 meters.

But often, relying on the “breathing” properties of wood, most builders do not adhere to these rules.

After completing the voluminous and complex installation of the roof, another important work remains - filing the roof overhangs. Some careless owners ignore this point or do it poorly. This is a necessary process through which a house acquires a designer look. Purely practical functions are also important - the under-roof space is now reliably protected from the wind and ventilation is provided.

Various materials are used for decoration, both those used for other purposes and those created specifically. Each of them has its own installation specifics, which are determined by the properties of the products. For quality work you will need some basic skills and simple tools. Then doing the hemming yourself is quite feasible.

Roof overhangs of a house - design features and functions

The roof eaves are hemmed not only to protect the attic space, but also serves the purpose of decorating the house. The building has clear advantages:

  • the design acquires a complete appearance;
  • there is an additional opportunity to regulate the thermal insulation of internal premises;
  • roof elements are protected from the harmful effects of precipitation.

The eaves overhang is the part of the rafters that protrudes beyond the facade of the building. It has different designs: simple or with extension. The first option is not difficult to perform; strong winds do not cause humming, which suffers from the second option, which is also more difficult to work with. The sheathing is made in such a way that it is possible to install gutters and ventilate the roof.

It is recommended to trim the overhangs after installing the rafters, when the sheathing for the roofing has not yet been nailed. Waterproofing is pre-installed and the roof is insulated. If you plan to finish the walls, it is carried out after so as not to damage the cornices when decorating. They are hemmed by everyone, regardless of the design features: what type of roof, the size of the projections.

Houses have two types of overhangs: side overhangs for all structures and front overhangs. The latter protect the facade; hip roofs do not have them. On a conventional gable roof, they are performed on sheathing boards extended beyond the gable. Sometimes they make load-bearing crossbars that are fixed to the rafters. In both cases, the board is hemmed from below.

All sloping roofs have side overhangs. They are formed by rafters, the edge of which protrudes further than the walls of the house. The protrusion depends on the height of the building, the size of the blind area and ranges from 0.5 m to 0.7 m, although there are also narrower ones. In this case, good protection of the walls is required - when it rains and winds, they get very wet.


Correct the situation when the rafters are insufficiently long by installing fillies. The process is quite complicated, and not everyone wants to bother with such work. Therefore, the dimensions of the overhang are determined during the construction of the roof.


At the same time as protection from atmospheric influences, the eaves are designed to provide good natural ventilation of the roofing pie. This is equally important for the attic and cold attic. The air should not encounter obstacles, move between the roof elements and exit through the ridge, otherwise condensation will form. Therefore, sealants and polyurethane foam are not used. The exception is frontal structures performed “deaf”.

Materials for filing cornices - which one to choose

The assortment is very large, each of the types used for finishing overhangs has its own advantages and disadvantages. When installed correctly, they provide moisture protection and ventilation. When purchasing, take into account the appearance and duration of operation. Most materials have other uses in home construction but are capable of serving a function in roof overhangs.


There are also products specially designed for this purpose - soffits. It is easy to work with and does not require complex expensive tools. They are immediately ready for installation; no additional operations are required. Regardless of the material of the spotlights and features, they are installed effortlessly even by beginners. The main difference is the location is not along the wall, but perpendicular. The peculiarity of the design is that it is providedventilation holes. A variety of materials are used for manufacturing:

  1. 1. Copper - products made from it are very aesthetic and presentable, but expensive. They are characterized by increased fire resistance and strength.
  2. 2. Aluminum - ultra-light, elastic, repairable elements. They are coated with UV-resistant paint, so the saturation is not lost. The decorative effect is low - shades of white and brown.
  3. 3. Galvanized soffit is durable, strong, and does not require additional maintenance. It has significant weight, which creates difficulties during installation.
  4. 4. Vinyl - inexpensive and most popular material. It is lightweight, beautiful to look at, easy to install, and produces a seamless canvas. The plastic is fire-resistant and can withstand significant loads. Products are produced without ventilation holes, completely perforated or only in the center.

Wooden lining is also widely used for lining overhangs. The ease of installation and good performance characteristics are attractive. The choice of material is carried out taking into account a number of nuances. Pay attention to thickness (at least 2 cm) and strength. The second indicator is humidity. Not suitable with elevated temperature, too dry. Since the products are in the open air, exposed to the atmosphere, care is taken to protect them - they are treated with antiseptics and water-repellent agents.


Edged boards are another material often used to construct eaves overhangs. The characteristics of the wood are taken into account. To achieve optimal humidity, store in the shade in the air for at least a month. In order to maintain aesthetics, products without noticeable defects are selected and processed with a plane before installation. The use of protective compounds is mandatory.


Corrugated sheeting is galvanized steel coated with multi-colored polymers. The panels are cut to the size of the overhang. To ensure ventilation, a gap is left between the cladding and the wall of the building corresponding to the wavelength. The material is not afraid of mechanical damage and temperature changes. The corrugated sheet has increased rigidity and is resistant to wind loads.


For filing overhangs, siding is used, which is used when finishing the facade. The option is acceptable, but there are points that should be taken into account. The plastic is fragile, but it can serve for a long time. Another material is PVC lining. For installation, U-shaped strips are purchased, which are used to trim the edges. The joints are connected with special corners.

All materials must:

  • reliably protect the eaves of the roof from all kinds of precipitation, frost, wind;
  • provide ventilation for a multi-layer roof;
  • be resistant to external influences and durable;
  • decorate the building structure.

Compliance with all the conditions for the choice of material and installation will make it possible to make overhangs aesthetically pleasing and practical.

Two technologies for finishing protrusions - start with rafter preparation

The options for lining the roof overhangs differ in their design features. If the slopes have a small angle of inclination, installation is carried out along the rafters. Their legs should be at the same level in any case. This will allow you to subsequently install the wind bar perfectly evenly. They are leveled, and if the length is not enough, additional boards are filled - fillies. The ends are processed by making vertical cuts.

Installation of overhang on rafters

Antiseptic and painting are applied to the rafters and finishing material (if necessary) before installation. The outermost board is fixed exactly along the overhang line. The cord is pulled and the rest of the sheathing is installed along it. The location is chosen perpendicular to the wall or parallel if the material is long.

Box design

The second option involves creating a box. Used on hip roofs and those with a steep slope. The method is used more often and looks more beautiful. Rafters are cut in two directions - horizontal and vertical. If the overhang width is more than 45 cm, an additional board is fixed in the middle. In the future, do-it-yourself hemming looks like this:

  • the material is treated with an antiseptic and painted;
  • a board is installed on the rafters below;
  • 1 cm above it, a beam or metal profile is fixed on the wall;
  • The binder is mounted sequentially, one end is attached to the rail, the other to the board.

The design of the protrusions requires the creation of ventilation holes. If these are not soffits, in which they are provided for by the design, proceed as follows:

  • retreat from the wall by 2 cm;
  • create gaps between elements;
  • install gratings at equal intervals.

Features of using spotlights

This is a separate group of material that is sold complete with all the parts necessary for installation. It is very easy to prepare the products for installation. When choosing, focus on the following parameters:

  1. 1. Dimensions - it is impossible to give definite advice. It all depends on the width of the overhang and the length of the roof span.
  2. 2. Color range - represented in a variety of shades. They proceed from the unity of the design style.
  3. 3. Presence of perforation. It is not needed for the gable overhang; with partial hemming, cornices are hemmed; with full, it is suitable for projections of any type.

To attach the spotlights, special profiles are used that resemble the letters J or F. One strip is installed on a rail, which is located on the wall of the house, the other - opposite on the front board. Fixed with self-tapping screws. Strict parallelism is observed, so marking is carried out first.

Installation of soffit overhangs

Measure the width of the overhang from the inner end of one profile to another. From the obtained result, subtract 5 mm, which is necessary to compensate for the thermal expansion of the material. Soffit strips are cut. They are bent slightly and inserted into the grooves, additionally secured with screws. The individual panels are connected to each other with locks provided by the design.


One of the possible options is not to use J or F slats on the overhang side, but to immediately screw in the trim elements. Then the ends are covered with an L profile (front strip), which simultaneously serves as a wind visor.


To hem the corners of the cornice, the length of the soffits is gradually reduced. One side is cut at 45°. Connect diagonally with an H profile or two J profiles.

For a high-quality result, a number of requirements are adhered to:

  1. 1. Installation is carried out through special holes at an angle of 90°; drilling yourself, except for metal products, is not recommended. This leads to deformation.
  2. 2. Self-tapping screws are used for fixation, minimum length is 20 mm. Their caps have a diameter of 8 mm. Do not tighten it tightly, leave a gap of 1 mm so that the soffits do not collapse due to temperature changes.
  3. 3. The workpieces are cut with a circular saw, turning it so that the teeth point in the opposite direction. Metal scissors are also used. If only a knife is available, use it to draw a line and break off the panel along it.

Despite the manufacturers' assurances about the possibility of installation in winter, it is better to postpone work in frosts below 15° and wait for warmer weather.

Using lining and edged boards

Of all lumber, these are the most popular. They decorate the ledges of not only wooden houses, but also brick, stone, and concrete ones. The thickness of the board is chosen from 15 to 20 mm. If installed parallel to the wall along the rafters, the width is adjusted to the location. At the same time, it is taken into account that the joints of adjacent rows are not placed on one rafter, but in a checkerboard pattern.

When fastening perpendicularly to the box, blanks of the required length are cut. To save on lining strips, choose parameters that will result in the least amount of waste. In all cases, they are sewn with self-tapping screws, which provide a more reliable fastening than nails. In places where the roof breaks on adjacent walls, parts are cut off on one side at an angle of 45°.


When choosing materials, pay attention to the type of wood. Spruce and larch have excellent performance properties - strength, resistance to rotting. Pine has good performance.

When using other materials: PVC lining, siding, corrugated sheeting, the technology does not differ significantly. One of two options for filing is used - along the rafters or the box. For plastic products you will need installation profiles. Do not forget about ventilation - its presence is mandatory. Arrange in the most suitable way for a particular material; leave gaps or install grilles.












Roofing is a very important stage in construction. Success in it is guaranteed by a pleasant and neat appearance of the building, be it a home, office, or utility room. A well-lined roof can protect the walls of the house from bad weather, and it can also have an excellent ventilation system that will ensure a long life for the entire roof. After reading this article, you will learn how to properly hem and what materials should be chosen for this.

Why are overhangs needed?

A roof overhang is the overhang of the roof that extends from the bottom of the roof. The recommended overhang width is 40 - 50 centimeters. Hemming of roof overhangs is a mandatory operation during the construction process. However, if you do not plan such a process, serious troubles may arise. The worst thing happens when a strong wind undermines the entire roof, passing through unlined overhangs. And the correct lining of the roof overhangs hides all the insides of the roofing pie and gives the building a finished look.

Important! Before carrying out lining work, you should complete the installation of the roof and also insulate the walls.

Types of overhangs

Structurally, overhangs are divided into only two main types: cornice and pediment.

Cornice overhangs

The lower horizontal part of the roof slopes is called the eaves overhang. It plays a key role in roof ventilation. The fact is that air enters through it, which either passes through the attic, as with attic-type roofs, or through the roofing pie, as with attic-type roofs, and then leaves through the ridge. Therefore, you cannot nail down the overhang tightly, because in this case air will not pass through.

A well-made sheathing should provide sufficient ventilation of the under-roof space Source interistroy.ru

There are several ways to ventilate your roof. Firstly, you can leave a gap between the wall and the lining material. It should not be too big, about one and a half centimeters. Secondly, the use of sheet materials when filing overhangs makes it possible to use ready-made ventilation grilles. Thirdly, if the overhang is hemmed with boards, we can simply make gaps between them. But in the case when the roof, for example, is based on bitumen, it is worth increasing the area of ​​​​the ventilation holes compared to, for example, clay tiles, since the first does not allow air to pass through at all. It is also worth covering all openings with nets to prevent contamination of the roof or attic.

The side part of the roof overhang is the gable overhang. The list of its functions does not include ventilation, but its main task is to reliably protect the entire roofing pie. Otherwise, the systematic entry of moisture will nullify all the efforts of your insulation, which is located in the roofing pie, and the room will become noticeably colder. When it comes to front overhangs, the most important goal is airtightness.

How to trim an overhang edge

Each type of overhang will necessarily have uncovered elements, such as the end parts of the rafters, as well as the ends of the sheathing. You will definitely need to decorate them beautifully, protecting them from bad weather and all external factors. The choice of materials for lining roof overhangs directly depends on what you used as roofing.

Before starting work, you should cut off all protruding rafters and sheathing elements at the same distance from the wall. After this, you must cover them with a strapping board, to which the front board is then attached. It is necessary to cover all wooden elements with protective compounds and it is better to paint if it is made of wood. It is also necessary to provide attachment points for gutters. On the front overhang, you need to nail the end board to the cut parts of the sheathing, and only then use roofing materials to finish it.

Options for filing overhangs

There are many options for filing overhangs, but the most common are the following:

    Eaves lining along rafters. This method is the easiest of all possible, but it requires that all rafters lie strictly at the same level and in the same plane. It is suitable for roofs with a slope of no more than 30 degrees and an overhang of up to 50 centimeters. The sheathing material is attached to the sheathing, which in turn rests on the roof frame. It will be better and more convenient if the hemming strips are stuffed perpendicular to the rafters.

    Horizontal filing. Very fast and economical in terms of material, hemming the roof. In order to carry out this option, you must first assemble a box of two boards, and only then attach it to the rafters. The board covering the end should end slightly lower than the vertical one, so that water falling on it can easily roll down. If the width of the overhang is about 50 centimeters, then another longitudinal board will be needed in its middle. This is a ready-made frame for installing roofing materials. This method is well suited for roofs with a large slope.

An important point is that the frame is always assembled from beams and boards, and lining materials are already attached to them.

How to choose materials

If you are planning such an operation as lining the roof with boards, then coniferous wood would be better for these purposes. The board must be thoroughly dried, otherwise it will warp later. It is imperative to treat it with paint and varnish coatings to protect it from mold and moisture. This material can be hemmed parallel and perpendicular to the wall.

A good option is wooden lining. Its advantages over the board are that it is already processed. However, for such purposes it must be water-resistant, and it must also be dried and processed. When hemming with this material, you can use ready-made grilles for ventilation.

Polyvinyl chloride siding- another material option. Only waterproof material should be used for hemming. All accessories can be purchased in special stores. You should not attach such material along the wall, because over time it can bend greatly.

Very easy to use and affordable material is corrugated sheet. It is distinguished by its lightness, strength and durability, as well as its affordable price compared to other materials. If the choice fell on this option, then when filing it is worth leaving ventilation gaps a little more than a centimeter.

You can also use sheets of waterproof plywood or OSB, as well as galvanized or polymer-coated steel, aluminum or copper.

Covering roof overhangs using soffits

Lining the roof using soffits is one of the most rational methods.

The soffits themselves are strips that are produced specifically for lining roof overhangs and are a very convenient and fairly affordable means. They can be made from any material from PVC to metal. Various colors and styles allow you to choose soffits for any home. Typically, this hemming material is sold complete with everything necessary, including fittings and fasteners.

Soffits are usually sold as panels, which can have one, two or three layers. Soffits can also be solid or perforated. This method of filing is very simple and relevant, since installing soffits on the roof eaves does not require special skills and abilities, as well as spending a lot of time.

One of the most popular methods of lining roof overhangs with soffits is horizontal lining. When using this method, a sheathing is made and attached to the roof overhang. Then a profile cut to size is attached to the sheathing. Such a profile is usually cut with a grinder and attached to the sheathing with self-tapping screws. There should be two strips - one at the wall, and the other at the edge of the overhang.

Careful measurements are the basis of any construction work Source interistroy.ru

Then the plate is inserted first into a profile located near the wall, and then at the end of the overhang. The gable part of the overhang can also be covered with a soffit.

Common mistakes when working with spotlights

    If the work is carried out by professionals, then the filing should be neat and beautiful.

    Special attention must be paid fastening reliability soffit panels, you should never skimp on fastening materials and fittings, otherwise a strong wind can undermine the entire structure.

    Be sure to finish before filing decoration of external walls.

Another important note: for filing overhangs, you should definitely get stainless fittings so that later rust does not spoil the appearance of the building.
