Wood, lining, spotlights, corrugated board + Video When building a house, each stage is important, be it laying the foundation or installing the roof. The lining of the eaves gives the roof an attractive appearance and also serves as a protection for the facade and helps to ventilate the building. Options can be very diverse from ordinary wooden lining to soffits.

Sewing of the roof overhang is performed after the installation of truss structures and before the sheathing for the roofing material.

Before direct filing of the cornice, it will be necessary to lay a waterproofing material on the roof, and it is also recommended to insulate the roof from the attic side.

Protection and ventilation

The main task of the eaves is to protect the roof from precipitation. It also plays a role in natural ventilation, which is a prerequisite for the construction of any building. So accumulations of warm air should go outside the ridge insulation, making a way from the bottom of the building through the ventilation of the cornice, through the waterproofing and gaps in the roofing material.

No polyurethane foam or sealants are used here. If you create a tightness, then this will contribute to the formation of condensation, which in turn will serve as a humidifier for the roof insulation.

Note: Ventilated cornices are used for filing roof slopes. Deaf ones are used for frontal overhangs.

Roof concept

Wood, lining, spotlights, corrugated board + Video Overhang is the lower part of the roof protruding beyond the walls of the structure ...

The overhang plays a protective role for the walls and foundations of the house. It happens in width from 20cm to 1m.

The roof is sutured after all its finishing works, as well as after insulation and finishing of all exterior walls of the house. Eaves filing is the final stage in construction.

Overhangs can be divided into horizontal or eaves and frontal.

The first type is formed on the lower roof slope. The main task of the horizontal ones, as mentioned earlier, is to create ventilation. The second is considered to be an inclined overhang, forming an assembly near the pediment. In the case of frontal ones, they serve as wall protection against moisture and wind.

Methods of device

The suture of the eaves is performed upon completion of all installation work of the frame device and adjustment of the outgoing rafter edges to size.

There are several ways:

  1. Along the rafters;
  2. Horizontal finishing along the box.

In the first method, it is necessary to make the ends of the rafters one level at a time. A thread is pulled between the first and last planks. All subsequent elements are mounted at this level.

The second option is more common.

Here, the rafters are cut on both sides. Boards are nailed from the bottom of the rafters, a bar is attached to the wall one centimeter higher than the frontal board to ensure the descent of moisture. If the overhang width is over 450 millimeters, then an additional board is attached in the middle.


Earlier, the eaves of the roofs were upholstered with a conventional edged board. But today materials such as wooden board, wooden and pvc lining, soffits, pvc siding, metal, as well as corrugated board are used.

Wood is a natural material ideal for hemming roof slopes. It is recommended to choose softwood with a width of 50-250 mm and a thickness of 17-22 mm. However, wood has such a disadvantage as the ability to deform and rot in wet conditions. To prevent this, special impregnating and protective substances are used.

For your information: Wood, like lining, must be kept outdoors before installation.

For ventilation, the boards are not stacked tightly, but with small gaps. The tree is easy enough to work with, but it is necessary to have the appropriate tools and skills.

Wood, lining, spotlights, corrugated board + Video For filing, wooden lining should be selected taking into account its operation in the open air, that is, the wood must be thick , with medium humidity to prevent drying and distortion.

PVC lining is a more inexpensive and easy-to-use material. The advantage here is that it does not need to be further processed, it is already usable.

It is recommended to keep the lining in the open air for about a month before laying it. The installation of the lining is carried out with a step width of 1.5 m, between which a lattice is installed, since there is no way to make gaps due to the fastening of the spike in the groove.

Soffits are available in the form of aluminum, plastic, copper, vinyl or galvanized panels. Outwardly, this material is similar to siding, but it is made of thicker plastic and provided with perforations to create ventilation processes.

This material is practical, resistant to natural phenomena and a variety of colors.

These panels are cut according to the size of the overhang and attached at an angle of 90 degrees to the wall.

The package includes:

  • panels;
  • front bevel;
  • J-shaped bar.

J-profiles are grooved. They are attached along the eaves, and the sheets themselves are located between them.

It has many advantages. It does not rot, it is not affected by humidity, and is also available in a large assortment. It gives an aesthetic appearance and installation work on its device is very simple. After all, there are a huge number of different special devices for the device, corners, profiles.

Profiled steel sheets are called profiled sheets.

It has reliability, high rigidity, solidity, as well as resistance to external influences and temperature extremes. The sheets are cut with a grinder into strips corresponding to the overhang and attached along the wall.

The outer corners are fixed at the outer joints of the sheets. Grilles are provided for ventilation.Profiles come in from eight to twenty millimeters in height.

To prevent corrosion processes, plastic strips are attached at the edges.


Eaves filing is an integral part of any roof structure. It is an excellent protection for your home and a beautiful appearance. You only need to decide on the method of attachment and purchase the necessary material. And a huge plus is that today there is a wide variety of options.
