Sheathing the eaves of the house with siding: professional advice, instructions + Video Do-it-yourself siding of the cornice - technique, features, photos. Installation of a roof includes a huge number of processes, including the installation of rafters, installation of thermal insulation material, and installation of roofing material. At the end of the work, you should take care of the siding of the cornice. Ideally, the roof should be at least 0.5-0 away from the wall.

7 meters, since it is this distance that will help create reliable protection of the wall from rain.

With this distance, an overhang is obtained, which is covered from above with roofing material, and various materials are used for protection from below. You should choose the material that will help provide reliable protection and ventilation of the space under the roof.

General information

At the moment, the construction market has a large selection of materials, and the most popular is siding, which was mentioned at the beginning. Sheathing with this particular material is the best option.

Siding is panels that can be in any color and shade.

In addition, additional fasteners, profiles and strips are produced for installation. The components as a whole make it possible to create an outwardly attractive structure that will protect the cornice from environmental influences.

And most importantly, all work can be done by hand, if you follow the recommendation of specialists and do everything exactly according to the installation technology.


Choice of siding

For cladding the cornice with siding with your own hands, you can use not only the material created on based on PVC.

The use of varieties of wood siding, i.e. lining or galvanized metal siding, is suitable.

But despite the variety of varieties, vinyl is used much more often. This is due to the fact that it is quite light in weight, but at the same time has excellent reliability and durability.

It is a thin sheet with a length of 300 to 360 cm. Each panel has special profiled strips with a size of 10 to 12 cm.

For fastening siding, locking systems are installed on the sides. For installation, manufacturers have developed a huge number of components.

For cladding, there are special panels called soffits, which have two varieties:

  1. Panel without perforation.

  2. Panel partially perforated.

For the case of cornice cladding, it is recommended to use spotlights with partial perforation. Thanks to the presence of these holes, you will get a high level of ventilation of the roof space.

Materials for filing

Modern the construction market has enough materials that can be used for cladding.

The most popular varieties are:

  • Wooden- material is relatively short-lived, subject to the negative effects of moisture; if the quality of production is poor, over time the material will begin to darken, and in addition, due to the lack of perforation, air circulation will be disrupted, which also entails problems.

  • Vinyl - these are polyvinyl chloride panels, in which there is no perforation, and most often this type of siding is used for facade cladding, and is rarely used for cornice; do not try to make perforations yourself, as this will only ruin the beautiful appearance.
  • Galvanized - , like other metal products, is subject to corrosion, which affects the service life, making it less than expected.
  • Vinyl soffit - it was developed specifically for sheathing cornices, moreover, it is denser and can have various perforations.
  • Aluminum soffit - This type of material is made from a thin sheet of aluminum and has a colored coating. Outwardly, it is somewhat similar to vinyl soffit, but when comparing characteristics, it has high reliability and durability.

Soffit for covering the cornice - a panel made of aluminum or polyvinyl chloride. Its length is from 300 to 360 cm. Dimensions depend only on the manufacturer. The best option is a soffit, which is 30 cm wide and 360 cm long.Depending on the perforation, the soffits are divided into three groups:

  1. Solid, and it is most often used for filing ceiling on a terrace, porch or veranda.

  2. With full perforation, which is advised to use in cases where the roofing material is not equipped with perforations, for example, shingles or rebates.
  3. Partially perforated to provide adequate ventilation. In addition, such a soffit looks great externally, and when buying, all components should be bought from the same manufacturer to ensure the best result of the finished work.

Soffit is most often made in only two colors, and it is dark brown and white. But let's note who some manufacturers offer a wide range of beige material shades.

Features of PVC spotlights

When sheathing the eaves of a house with siding, you should adhere to certain rules that were created based on the characteristics of the material.

  1. Before starting work, the purchased material should be placed in a place where it will not be exposed to direct sunlight. In this case, the temperature should not be more than +60 degrees.
  2. It is very important to consider when sheathing that the siding panels must have a certain freedom of movement horizontally, since the material will expand when heated. If done correctly, the material will not deform during expansion.

  3. When fastening, do not screw in the self-tapping screws too much, as this can lead to breakage of the locking system.
  4. Any kind of spotlights should be attached only to self-tapping screws.
  5. There should be a gap of 0.1 cm between the siding and the head of the screw in order for the panels to move slightly. This will also prevent deformation.

  6. The use of sealant between panels and corner joints is not recommended.
  7. When installing the optional mount, be careful not to damage the panels.

Following these rules will give excellent results and you will not have to call a specialist for these works or redo everything again.

Box construction

In order to cover the cornice with perforated siding, it is worth making a box first. For the construction, wooden blocks or aluminum profiles can be used.

There are certain rules. If you will sheathe the cornice with clapboard (i.e., wooden siding), then the frame should be made only of wooden blocks. In this case, the use of a metal profile is unacceptable.

It will only work if you will be using galvanized or vinyl siding.

Please note that in order for the siding to be evenly fixed in the future, the first profile should always be fixed to the wall.

In this case, it is important that a horizontal line is maintained, otherwise the siding will be installed incorrectly and unevenly. If the roof has a slight slope, the filing can be done using the rafter system. To do this, it is required to install 10 * 4 cm bars on the underside of the rafters.

This is required in order to obtain a horizontal and even plane. It will be more correct to install the bars along the stretched cord, which should be fastened between the extreme bars.

If the roof slope has a large slope, it is worth making a box of two bars. One bar or profile should be attached to the rafters, and the second to the wall. We install transverse bars on the boards, on which the soffit will be attached in the future.

Note that the soffits are simple to install, but nevertheless, the matter should be approached with awareness and thoroughness, since in addition to the decorative function, they can perform a functional load. Such a cornice will help protect the structure from moisture in the event of precipitation or melting snow and wind.


All work on installing any type of soffit begins with the fact that you need to install parallel profiles, one of which is attached to the wall, and the second to the chamfer plane. It is in them that the spotlights will be installed. To select the correct profile, define the chamfer configuration.

At the moment, only two types of profiles, F and J, are produced.

If originally there were awnings on the roof, install a J profile that will follow the timber plank for the frame. It is important that the profile and bottom edge are flush. After installation, the trimmed soffits should be inserted.All joints of siding and soffits without perforation are easy to hide using a strip, which gives the structure an appearance of completeness.

Nuances and features

After the box of bars or aluminum profiles is ready, you can start plating the cornice of the house with siding with your own hands.

Here are some things to consider:

  • Prepare the rafter system before starting the sheathing. The preparation consists in the fact that all ends should be sawn at the same level and parallelism should be controlled relative to the walls.
  • Any cornice can be sheathed even with boards, but the aesthetics will be minimal. It is better to give preference to special strips, which will provide perforation and will be combined with the roofing material in color.

  • Before installing the box, file all the rafters so that the end part is protected by siding.

Separately, we note that all work on the facade insulation should be carried out before you completely make the covering of the roof overhang with vinyl siding.
