Metal profile is a material that is in high demand. It has been used as a roof covering in private houses, as well as other buildings for more than one year. At the same time, anyone with no experience can cope with the task. But before starting work on the installation of the crate under the metal tile, many questions arise:
- Choosing board size.
- Determining where to start laying.
These are important questions, as the life and reliability of the entire roof depends on it. Do not neglect external indicators, because the roof is always the first thing that catches your eye. Knowing the instructions and tips, you can easily start working on roofing. Do not neglect elementary actions, since if you make a small mistake at the beginning, you can come to disastrous consequences inend.
Functions and design
Crate under the metal tile is the foundation of the entire structure. During the operation of the house, several main functions are assigned to it:
- Rigidity of the roof slopes.
- Profile load uniformity.
- Transferring the load to the foundation.
According to the builders, it is important to choose the material from which the structure is being built. The most commonly used edged board. It is good if it is dried, so the service life increases significantly. Some use plywood. But in such a situation, it is worth calculating the load in order to choose the thickness. The crate under the metal tile has two main components. We will look at them below.
Control grille
Wooden slats are used. Their thickness can be up to five centimeters. They are fixed along the rafter legs of the frame, on top of the waterproofing material. This is an important material because it helps create ventilation gaps.
Crate for metal tile
It is superimposed perpendicular to the counter-lattice. The selected material is purchased in advance. The step of the crate under the metal tile and its size are pre-calculated. This indicator is influenced by the total load of the roofing material, weather conditions in the region, wind and other factors.
Both of these parts play a dominant role in the whole design. You need to do the right calculations beforehand, otherwise it maythe entire roof will open or collapse.
What kinds are there?
Now it is clear that the correct crate under the metal tile is the basis of the entire roof. This is a support that is able to distribute the load on the rafters. Durability will depend on the right creation. Builders say that the crate can be mounted in two ways:
- Without gaps (solid). To do this, use an edged board or plywood that is resistant to moisture. The laying process takes place without indentation. This type requires additional financial investments. It is used in the event that the roofing material itself strongly presses on the entire surface. Sometimes they do not make large slopes of the slopes, which also implies such a design. The process is carried out as follows. First, a counter-lattice is made, and after that - an already uniform flooring without gaps.
- The roof lathing under the metal tile is sparse. Edged or regular board is used. It is fixed at a certain distance. What size should the board be, as well as the step between it? This is calculated depending on the load. To protect the tree from negative influences, you need to treat it with an antiseptic. In addition, today there are compounds that block the fire.
Rafter system
It is believed that the basis of the roofing cake is the truss system. If this is a low-rise building, then select:
- Single or double.
- Hip system.
- Tent.
- Halm.
- Attic.
In this case, the choice of rafter boards for all will be the same. By presenting the necessary requirements, it is possible to achieve a long service life of the entire structure. If additional structures are planned on the roof - stairs, snow retainers, running ladders, then in this place it is necessary to strengthen the crate with additional boards.
How to choose the type of construction?
According to the masters, before starting construction, you need to study the data on the roofing material from the manufacturer itself. Because the distance in the crate will also depend on the wavelength of the roofing material. What kind of crate for a metal tile (including Monterrey) should be? You need to pay attention to elementary criteria:
- Slope level. It is believed that with an increase in this indicator, the distance between the components of the base can be expanded. When a decision is made that the roof is flat and low, then the counter-lattice and the flooring itself should become thicker and be made of durable material. Coniferous wood is often preferred because it is a durable material that has been tested over the years. The service life of such structures often reaches 50 years or more.
- Weight category. According to the builders, the entire structure usually weighs no more than five kilograms per square meter. Therefore, when calculating and choosing boards for the base, you should pay attention to external factors.
- Indicators of climate impact in the region. It is believed that the erection of a roof and the creation of a crate for any roofing material will be different, depending onthe severity of the winter. When there is a lot of snow, the structure must be stronger than where there is almost none. It turns out that the selected boards become stronger, and the step between them is smaller in the presence of heavy rainfall and vice versa.
- Profile wave. Everyone tries to create the most convenient conditions for installation work. In such a situation, it is worth considering every little thing. Masters of the construction business believe that the wavelength of the metal tile should correspond to the distance between the crate. This is relevant if there is no work experience.
When calculating the dimensions of the crate for metal tiles, including the pitch, the wavelength is taken into account. So fixing the sheets will be easier and faster. It is clear that a well-made base will help to avoid any problems and misunderstandings.
Insulation
Many believe that at the level of preparation, waterproofing should also be performed. After all, the insulated pie of the roof structure allows the use of an attic space in the cold season. And the creation of a beautiful attic in the attic is additional square meters. So, when building, you need to think about insulation. Do not forget that condensation may form on the structure. This leads to unpleasant consequences and rotting of the crate.
In the process of installation work, waterproofing materials and membranes are used. If a heater is laid, then it is no longer possible to do without such a protective film. Otherwise, moisture will definitely collect, giving heat loss. This design is fixed when using staples. Withoutcounter battens cannot cover the roof.
What should not be forgotten?
As already noted, the base of the roof is a crate. Its reliability will be high if the permanent and temporary loads are calculated with maximum accuracy. In addition, it is worth determining the dimensions of the crate for the metal tile. Additionally, you need to make an increase in strength. Here's what you definitely shouldn't lose sight of:
- If the roof is planned with a low slope, then the crate should be solid. In such construction, it will be appropriate to use moisture-resistant plywood. She is strong and reliable. And you can easily find it in any store.
- When the slope is performed with an average, then a lattice structure can already be allowed here. It is important to choose slats with a thickness of at least four centimeters. What step is allowed in such a construction? Masters of the construction industry believe that it is allowed to make it 15 centimeters.
- How does the main flooring line up under the roofing material at an angle of inclination of more than 40 degrees? The thickness of the rails is reduced to two centimeters, and a step of 20 centimeters is permissible. These are the most optimal indicators for such a design.
We have listed the main points when choosing a batten for roof decking. But there is one more feature - the surface should be as even as possible so that after fastening the metal tile does not walk on the roof (especially when exposed to strong winds in bad weather). So, the board should be as flat as possible. Sucheasy to find.
Installation of skates
What is a roof ridge? This is a structure that is fixed after the main work and is the center of the intersection of the roof slopes. It is considered ventilation of the under-roof space. In order for the roofing ridge to stand securely, additional boards are stuffed onto the rafters. If the parts are too tight, then the condensate will not drain completely. As a result, the tree will begin to succumb to decay and the effects of fungus. This will significantly reduce the service life. And iron will corrode.
The roof is the basis of any structure. And so do not forget about the appearance. Skates can be made both from the base material and from simple corrugated board, in color or not, it does not matter. Tiles are considered a beautiful material that can create a unique external combination.
How to attach skates to roofs?
They are first measured, then cut and bent. If these are two components, then you will have to create additional protection for the junction. For this, silicone or polyurethane foam is sometimes used. But it is better to try and make from a single design. Next, mark the connection points with the roof. Holes are made on the ground, and then, at the very height, they carry out a full-fledged fastening. We can say that after this the design will be ready.
If the roofing pie is done correctly, then it will not be difficult to cope with the flooring of the iron itself. It is important to follow the manufacturer's recommendations. Do not forget about heat and waterproofing and purchase high-qualitybuilding material.
So, we figured out how to make a crate for a metal tile.
