How difficult is it to make a roof from a metal tile with your own hands - an installation video for which is not difficult to find on the Internet? It is definitely difficult to answer. But this article will help shed some light on this issue.
In addition, the material provided will help those who nevertheless decide to do it themselves during the installation process.
Also, information on how to make a roof from a metal tile will be useful to customers who are going to hire someone to perform these works.
It is very important for them to imagine the laying process in order to monitor compliance with the technology, because the quality of the purchased metal tile does not mean that the proposed roof will be reliable and durable. A lot depends on the correctness and sequence of the work and the design of the roof.
To your attention! Particular attention should be paid to the ventilation of the roof, which prevents the formation of condensate on its surface. When purchasing a certain set of metal tiles, the manufacturer must provide you with information regarding the installation of the most complex elements.
Depending on which type of tile you choose, additional clarifications and recommendations may appear.
For example, sheets of different manufacturers having the same size may have different usable widths, on which the required "overlap" will depend. This can affect the installation features and the amount of material used.
In addition, for hip and hip types of roofs, in comparison with gable and single-pitched roofs, a larger amount of material is required, and the technological map for the installation of metal roofing includes a greater number of kinks.
And when arranging connections and outlets on the roof, the complexity of the work increases.
Consider the features of the installation of a metal roof on the example of a gable roof.
True, before purchasing materials for the roof, you need to perform the required calculations. Based on their results, you can accurately determine the number and length of sheets, as well as everything else that is required for fasteners.
- General information
Sheets of metal tiles are manufactured according to the dimensions indicated in the roof drawing, which is necessary for the ordered roofing kit to fit the parameters.
To do this, measure the batten and roof diagonally. Usually the length of the sheets is equal to the length of the slopes. The sheet should be laid so that it protrudes 4 cm beyond the eaves.
This is necessary in order to properly mount the gutter and create a ventilation slot under the ridge bar. Calculating the number of sheets is very simple: you just need to divide the length of the cornice by the useful width of the tile you have chosen.
Sheets of metal tiles are supplied according to size. When making calculations, roof protrusions should also be taken into account when sheets of different lengths are required for the slope. Such sheets must have a length equal to a multiple of the profile pitch.
If a hipped roof is being arranged, then the sheets are calculated one by one. At the same time, most of them are cut off and cannot be reused. This is due to the fact that the first profile wave has a capillary groove.
- Roofs with a complex structure
When calculating a hip or hip roof, you need to make a drawing on graph paper and calculate each sheet in sequence. Since there is a capillary groove on the first wave, this sheet cannot be used on the opposite slope, unlike gable roofs.
However, this also affects the amount of material used, which increases significantly. Such roofs require extremely accurate calculations, so it is better to leave them to a qualified specialist.
Otherwise, do-it-yourself metal roofing will not be possible.Usually, metal tile sellers have a special program that allows you to accurately and quickly calculate the number of sheets, as well as cut them for a roof of any complexity.
If there is a ledge on the roof slope, then it must be taken into account that the transverse pattern on the profile in this place must match. You also need to remember that if sheets of different lengths are required on the slope, then it must be a multiple of the drawing step.
- Ventilation
In the event that the scheme of the roof made of metal tiles does not provide for internal ventilation of the roof, then, rising to the roof, warm air from the house will form condensate on the inner surface of the tile sheet, in turn, which will begin to drain onto the ceiling of the lower floor or attic ceiling.
Ultimately, this will lead to a damaged finish and the formation of fungus.
There is a practical and effective solution to this problem, which allows you to turn the attic into another living space, including a hydro and roof insulation for the outer contour of the attic, natural ventilation created by the crate on the roof.
Good ventilation will be created if the air flow coming from the street penetrates from the side of the eaves, and exits back from under the ridge and through special ventilation holes in the gables.
As a result, a uniform blowing of the entire inner surface of the roof is formed, which will delay the repair of a roof made of metal.
If the building has rooms with high humidity, then it is necessary to make forced ventilation and additionally raise the crate so that the ventilation gap is not less than 5 cm.
This task can be facilitated with the help of ridge elements and other components included in the construction of a metal roof.
- Storage conditions
If the metal tile is in its original packaging, then it can be stored under a canopy for a month, after placing bars horizontally under it in increments of 50 cm.
For longer storage, it is necessary to shift each sheet with slats located above the bars. You need to transfer the sheets by the edges with special care so as not to cut your hands.
- Additional processing
Regardless of the fact that such material is already purchased with all issues, individual sheets may still need to be cut and adjusted at the junctions. You can cut the sheet along the length with scissors or a hacksaw for metal.
In order to make a bevel, it is better to use an electric saw with carbide teeth. The use of grinding machines with abrasive wheels for these purposes is strictly not allowed.
If, when installing a roof from a metal tile with your own hands, you have sawdust on it, then they must be swept away, as if left on the surface, they will cause corrosion.
If you scratched the surface of the polymer coating, then the zinc layer will still protect against corrosion, and scratches, so that they do not spoil the appearance, can be painted over with paint of the appropriate color.
Therefore, it is advisable to purchase a can of paint of the desired shade along with the metal tile.It is also better to use paint on sections, especially in those places where the wave deflection occurs and where the sheet was cut off.
- Lathing installation
In order not to require repair of a tiled roof in the near future, it is necessary to correctly and accurately mount the crate, which is directly related to the quality and durability of the roof.
It is necessary to make the crate without deviating from the drawing, which takes into account the natural ventilation of the roof and the features of the type of tile used. The location of the crate should include outlets and dormer windows, the exit of which will be on the roof.
In order to mark the crate correctly, you need to know exactly the type of metal tile being installed. Each species has its own range.
Natural ventilation is achieved thanks to the crate. In its manufacture, boards 32 by 100 mm are used. The board protruding beyond the eaves should exceed the thickness of the others by 1-1.5 cm.
Installation roof battens carried out on top of the waterproofing sheet, which is pressed against the beams and rafters with the help of slats. This forms a waterproofing with a gap that is sufficient for natural ventilation of the entire slope.
In addition, it should be noted that the waterproofing layer must prevent condensation even if poor natural ventilation is provided. roof material must absorb moisture.
At the same time, water vapor will not be able to reach the metal tile, and, consequently, condensation will not form on it. Moisture will be retained in the fibers until complete ventilation occurs.
The end plate must be placed above the crate by one sheet profile.To securely fasten the ridge bar under it on all slopes, you need to nail a pair of additional boards.
This must be done because the ridge bar experiences strong snow and wind loads. If you do not understand the construction of a metal roof, a video of this process will help you a lot.
Advice! By the way, the installation of the cornice strip should be carried out before the metal tile is laid. When marking the crate, it should be remembered that an overlap of 10 cm is required between the plank and sheets.
The plank is fastened with self-tapping screws or galvanized nails through 30 cm, which ensures its stability, regardless of the strength of the winds. The bar is cut with scissors for metal. All these elements can be purchased together with metal tiles.
As you can see, a metal tile roof - a video of the installation process of which you have probably already found, is not difficult if you approach this issue with all care.
