Roofing is the final stage of construction. It would seem that ahead is the interior decoration and arrangement of a new space. In fact, it is too early to believe that the building is ready for operation. It is necessary to complete some nuances, namely to hem the roof eaves.
Most owners of residential premises do not pay due attention to this moment either at the beginning, during, or even after construction work. Although this stage is the most important at the time of designing the roof. If you do not hem the roof eaves or install it incorrectly, ventilation problems may begin, water will accumulate in the attic or attic, which will lead to the formation of fungus and mold.
What is a curtain rod?
The cornice is also called an overhang. The first thing to do is figure out what it is. The overhang is considered to be part of the roof structure, which slightly extends beyond the walls of the building. The roof can be considered a mushroom hat, which protects the building from precipitation, thereby helping to drain it to the ground without touching the walls.
When filing the roof, the cornice should protrude from 40 to 50 centimeters. Not everyone adheres to common standards, since some make additional rooms under one roof slope, someone installs drainage and drainage, and there are cases when all this is combined and implemented as a whole. Therefore, when designing a plan for a future building, everything must be taken into account. Based on the data, it will be decided how long the ledge of the roof is needed. A good example is shown in the photo of the filing of the eaves of the roof.
Effects
Of course, you can make the roof so that it does not protrude, thereby freeing yourself from the need to hem the roof cornice. But this has its consequences. Water will flow down the walls, and the building will not be able to serve for a long time.
It would seem that since the absence of an overhang is so detrimental to the building, then you can make it as large as possible. But this is also wrong. The load on the walls will increase significantly, in addition, this entails more costs for building materials. First of all, you need to adhere to common sense and calculations during the design of the building. If you plan to place not only a house under one roof, but also a summer kitchen, a gazebo or something else, then you need to install transitions that will extend the roof without consequences.
Why hem the cornice?
This procedure is done in order to visually create the integrity of the building. It can also be used to implement design projects. If we consider the cornice as a structure, then thanks to its presence, the rise of the roof is prevented by strong gusts of wind. If it is hemmed incorrectly or not touched at all, then a strong wind can completely disrupt the roof. These cases are rare, but it is better to protect yourself in advance.
In those cases when the available area under the roof is not used as residential, the cornice is not tightly sheathed, which allows you to create the necessary climate in the attic.
The ability to create ventilated facades by installing an air duct under the ledge makes the system invisible.
Materials used
There are a lot of options for filing roof cornices. Consider the main ones.
Lining is a great option for a natural material to work with. This material is the most popular due to the fact that it can be treated with special impregnations that extend the operating life, and most importantly - originality in texture and pattern. You can perform work not only horizontally, but also at an angle. As a basis, wood or metal is used.
The profile sheet is in second place in terms of popularity. It is preferred for ease of installation, attractive appearance. The material is reliable and unpretentious to the base.
Plastic is used a little less often. But that does not make it less popular. When working with him, you need to responsibly approach the preparation of the foundation. This is due to the fact that any deviations immediately become noticeable. Plastic for filing roof eaves - an inexpensive option, but short-lived. Compared with the previous two options, it is very easy to damage.
MDF and laminate are used the same way. At first glance, MDF can be mistaken for quality material, but its operational life does not exceed 10 years. Laminate can not boast of such a period.
Spotlights are made in much the same way as panels using plastic, copper or aluminum. It is intended exclusively for finishing cornice. A distinctive feature is the need to install ventilated panels every 11 meters.
Boards are the most common and everyday material. They are used for independent construction work. Despite the variety of materials, the board does not lose its position in the market of goods and services. Thanks to technology, complex graphic designs and patterns can be applied to it.
Frame cladding
Before you make a binder of the cornice under the roof, you need to familiarize yourself with some of the nuances in the work and subsequently take them into account. Framing of the frame is carried out only after it is installed under the roof and the protruding edges of the roof are adjusted to the required size. The first board for the crate is mounted at the moment when the rafters are sawed off. In subsequent stages, this board will serve as a guide in the work. After this, the overhang is sheathed, but for this process it is necessary to choose a type of design.
Truss trim diagonally. This method is used for roofs that have a slight slope, or for a visual increase in the structure. To bind the cornice along the rafters, the lower parts of the legs must necessarily be located in the same plane. If this is not observed, then you will have to resort to alignment, and for this the boards will be mounted with an overlap. In the process, the first and last trims are mounted, and a thread is stretched between them. All other work is carried out with strict observance of the landmark.
Sheathing horizontally and vertically. This method is very popular. The legs of the rafters are cut horizontally or vertically. A board is attached to the bottom of the rafters, and a beam is attached to the wall in such a way that its height exceeds the height of the board by 10 millimeters. If the gap has a width of more than 45 centimeters, then in the center an additionally mount the board.
Before you hem the roof cornice with your own hands, a framework must be created. Regardless of the chosen method of work, they are performed in the same way: the boards are mounted on the crate parallel to the pediment.
Features of binder overhang clapboard
When carrying out construction work on the filing of the eaves of the roof lining can be an excellent material. Lining is not recommended to be used only if the roof has an incorrect parapet over the entire surface, which begins to protrude.
To use material for a pitched structure is relevant if the attic is planned to be equipped as a living room. Lining will help to balance the level of humidity in the winter season, create ventilation.
Conducting all the work yourself is not as difficult as it might seem at first glance. To work effectively, you need to know some features:
- Work is carried out at the moment when the process of installing the lathing begins, but the rafters are already installed. Rafter legs should be located at the same level, parallel to the walls of the building. Before starting work, they often turn to additional sources to visually see how to properly hem the roof eaves. A photo is a great option.
- It is necessary to take care in advance of the width of the cornice box, which does not differ along the entire perimeter of the roof. This helps give the structure an attractive look. Boards should be parallel to the walls.
If you carry out all the work carefully and efficiently, the process will move forward quickly and please the result.
Features of working with spotlights
A distinctive feature of spotlights is their resistance to mechanical stress and weather conditions. The surface of the material does not respond to direct sunlight and does not lose its original color over time.
Spotlights are used not only for external decoration of premises, but also for internal. The material, which is designed for curtain rods, is characterized by ease of installation, operation. It is considered environmentally friendly and safe.
For filing the eaves of roofs with spotlights, several steps must be performed in the work. Along the entire length of the overhang, several slats are installed. J or F type profiles are screwed to the underside of the first bar. The size of the panel should correspond to the width of the overhang. One edge of the finishing material is inserted into the groove, and the other is mounted to the second bar. After this, the slats are closed by the profile.
Spotlights can be used for both indoor and outdoor cornices.
With the overhang open, a profile should be installed on which the panel is subsequently mounted. Profiles are installed at the same level between the wall of the building and the cornice.
In those cases when it is planned to create ventilation, use perforated soffit during the hemming of the eaves of the roof. To install it, use a type J profile. If necessary, the surface can be leveled with a profile. All other work is performed in the same way as with an open overhang.
The key to the successful result of any work in the construction process is the competent and correct measurement. Everything else does not require special knowledge and skills.
Use of corrugated board in work
To work on the filing of the cornice of the roof with professional flooring, they begin after the installation of the coating for the roof. At the same time, systems can be installed to drain water.
Initially, it is required to evenly cut the legs of the rafters so that they are parallel to the walls. If the binder is made in the form of a box, then the frame must be insulated in advance.
After that, the bars are installed on the walls, on which boards for hemming are fixed on one side. From below the lath is fastened, on which the corrugated board will be mounted.
Often, the roof covering is used as an additional canopy over other buildings. For example, for a terrace, a balcony, a summer kitchen. In such cases, the ceiling is mounted simultaneously with the overhang.
Decking is attached to a pre-prepared frame. For ventilated facades, air flow is not obstructed. To do this, a small gap is left between the facing material and the wall of the building. To give an attractive look, you can mount a ventilation grill at the gaps.
Using a metal profile
Before starting work on the filing of the eaves of the roof with a metal profile, it is necessary to prepare a base on which the material will be fixed in the future.
- A board is attached to the wall to the bottom of the beam; a level and thread are used to level it.
- If the board does not fit snugly, you can align the beam. Clearances can be eliminated by improvised building material: plywood cutting.
- After the board lies flat, it must be firmly attached.
- Then proceed to fasten the next board, which is fixed in a horizontal position. After alignment, it is reattached.
- We proceed to the preparation of the metal profile.
- The profile is cut into strips of the desired length and width.
- On the profile, you need to prepare through holes for attaching to the frame.
- If the length is insufficient, the profile can dock with each other until the required length is obtained.
- The profile must be prepared in the required quantity.
- First, the sides of the cornice are mounted.
- The profile is attached to the frame, it is mounted on all sides of the overhang.
- After the metal profile is installed, corners are fastened, which can also be made independently.
Using siding
Until the siding began to be used for siding roof eaves, lining and board were popular. The main disadvantage of such materials could be attributed only to fragility. Under the influence of the environment and weather conditions, they quickly deteriorated and rotted. They had to be painted often enough, and sometimes completely replaced.
Using siding, you need to consider that not every type of it is suitable for work. For instance:
- Vinyl siding is used exclusively for facade cladding. On the eaves, it looks unattractive, collects a lot of fluid.
- Metal siding quickly becomes rusty due to the abundance of water.
Before you start installing the eaves using siding, you should know one feature. Installation should be carried out before the roofing works are started. It is also not recommended to drive nails into the material, this can lead to the formation of cracks and rapid destruction.
