Filing of the roof is a very important stage in construction. Success in it guarantees a pleasant and neat appearance of the building, whether it be a house, an office, or an utility room. A well-hemmed roof can protect the walls of the house from the weather, and in it you can make an excellent ventilation system that will ensure a long life for the entire roof. After reading this article, you will learn how to correctly produce a binder and what materials to choose for this.
The roof overhang is a roof ledge which is located below the roof. The recommended width of the overhang is 40 - 50 centimeters. Filing a roof overhang is a mandatory operation during construction. However, if you do not plan such a process, then serious trouble may arise. The most terrible thing happens when a strong wind undermines the entire roof, passing through unfixed overhangs. And even the right overhang of roof overhangs hides all the insides of the roofing pie and gives the building a finished look.
Important! Before you do the binding work, you must complete the installation of the roof and also insulate the walls.
Structurally, overhangs are divided into only two main types: curtain rods and pediment.
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 through it enters the air, which either passes through the attic, like the roofs of the attic type, or through the roofing pie, like the roofs of the attic type, and then leaves through the ridge. Therefore, it is impossible to close up the overhang tightly, because in this case air will not pass.
There are several ways to make roof ventilation. First, you can leave a gap between the wall and the cushioning material. It should not be too big, about one and a half centimeters. Secondly, the use of sheet materials when filing the overhangs makes it possible to use ready-made ventilation grilles. Thirdly, if the overhang is hemmed with boards, we can simply make a gap between them. But in the case when the roof, for example, on the basis of bitumen, it is worthwhile to increase the area of the ventilation holes, as compared to, for example, clay tiles, since the first one does not let air in at all. And also it is necessary to close all the openings with nets to prevent the roof or attic from being contaminated.
The side of the overhang of the roof is a gable overhang. The list of its functions does not mean ventilation, but its main task is to reliably protect the entire roofing pie. Otherwise, the systematic ingress of moisture will reduce to zero all the efforts of your insulation, which is in the roofing cake, and the room will become noticeably colder. When it comes to frontal overhangs, the main goal is tightness.

Each type of overhang will always have unclosed elements, such as the end parts of the rafters, as well as the ends of the sheathing. It will be necessary to decorate them beautifully, protecting them from the weather and all external factors. The choice of materials for filing overhangs of the roof depends on what you used as a roof covering.
Before starting work, all protruding rafters and elements of sheathing should be cut off at the same distance from the wall. After this, it is necessary to cover them with a strapping board, to which the frontal 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. You also need to provide attachment points for gutters. On the front overhang, it is necessary to nail the butt board to the trimmed parts of the batten, and only then use the roofing materials for its finishing.
There are so many options for bindering overhangs The following are common:
Filing of the overhang along the rafters . This method is the easiest of all possible, but it requires that all the rafters lay strictly on the same level and in the same plane. It is suitable for roofs with a slope of no more than 30 degrees and a protrusion of up to 50 centimeters. The cushioning material is attached to the batten, which in turn rests on the roof frame. It will be better and more convenient if the stitches are perpendicular to the rafters.
Horizontal Binder . Very fast and economical in terms of material hemming the roof.In order to perform this option, you must first assemble a box of two boards, and only then attach it to the rafters. The board covering the butt should end slightly lower than the vertical one in order for the water falling on it to easily slide down. If the width of the overhang is about 50 centimeters, then another longitudinal plank will be needed in the middle of it. This is a finished frame for mounting roofing materials. This method is well suited for roofs with a large angle.
An important point, the frame is always assembled from bars and planks, and already attached to them hemming materials.
If you are planning an operation like hemming roof boards, it will be better for these purposes softwood. The board must be thoroughly dried, otherwise it will warp. Be sure to treat it with paint coatings to protect from mold and moisture. This material can be stitched parallel and perpendicular to the wall.
A good option is wooden lining . Its advantages over the board is that it has already been processed. However, for such purposes it must be water resistant, it should also be dried and processed. When filing this material for ventilation, you can use ready-made grilles.
PVC siding is another version of the material. For filing should only be used waterproof material. All accessories can be purchased in special stores. It is not necessary to fasten such material along the wall, because over time it can bend strongly.
Very easy to use and affordable material is decking . It differs in ease, durability and durability, and also the price, available in comparison with other materials. If the choice fell on this option, then when filing it is necessary to leave the ventilation gaps slightly 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.

Filing the roof using spotlights is one of the most rational ways.
By themselves, spotlights are strips that are produced specifically for filing roof overhangs and are very convenient and fairly affordable means. They can be made from any material from PVC to metal. Different colors and styles will allow you to pick up spotlights for any home. Usually this stitching material is sold with everything you need, including fittings and fasteners.
Soffits are usually sold in the form of panels, which can have one, two or three layers. Also spotlights are solid and perforated. This method of filing is very simple and relevant, as the installation of spotlights on the roof eaves does not require special skills and abilities, as well as the cost of a large amount of time.
One of the most popular ways of filing overhangs of a roof with spotlights is horizontal binder. When using this method, the batten is made and mounted on the overhang of the roof. Then the profile is cut to the sheathing, cut to size. Such a profile is usually cut by a grinder, and fastened 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.
Then the plate is inserted first into the profile located near the wall and then at the end of the overhang . The front part of the overhang can also be sewn up using a soffit.
In more detail about the installation of spotlights, this video will tell you:
If the work is done by professionals, then the file should be neat and beautiful .
Separate attention should be paid to the reliability of fasteners of the soffit panels; you can never save fixing materials and accessories, otherwise a strong wind could undermine the entire structure.
Be sure to finish the exterior walls before the sheet set.
One more important note, for filing the overhangs, you should definitely get stainless fittings so that rust will not spoil the appearance of the building.
