Slate is a fairly common building material - it is caused by its durability, and ease of operation, and low cost. In the vast majority of cases it is used for roofing equipment. Let's look briefly, how to properly place the sheets, what and how to nail slate?
Layout of sheets
In practice, two methods are used. At the first, the edges of adjacent sheets are combined, at the second - they overlap( wave of the next sheet on the wave of the previous one).The way of combining is more labor-consuming and requires certain skills and accuracy.
The second method is simpler, but also more expensive, because the overlap reduces the width of the sheets, hence, the consumption increases. With this method, one must also take into account the direction of the prevailing wind. Therefore, sheets need to be stacked so that the "junction" of the sheets is located in its direction. Otherwise, the top sheet will "try" to rise under the gusts of the wind.
Than nailing
It is best to use special slate nails with the necessary boring. In this case, it will not be necessary to drill slate sheets. But if at hand there is nothing, except for the usual long nails, then you can nail the sheets and them. You can also use self-tapping screws, but you will have to drill a sheet. In addition, you will need to find suitable washers under the head of the nail( samoreza).If the roof design is not important, instead of washers, you can use any suitable material( pieces of tin, dense skin, thick rubber, etc.).
How to nail
It should be understood that the quality of the roof half depends on how it was laid. Therefore, before nailing slate, you need to do the preparatory work:
- gutters should be installed in advance, otherwise there will be some inconvenience when installing them;
- to construct a crate on the roof surface - it is to its slats and it will be necessary to nail the slate. The fact is that not all roof boards( if their laying is continuous) are in perfect condition. It may happen that the tree is rotten in the place where the nail is driven, which means that the nail will not hold well. And drill a lot of holes in the slate to find a "strong" place? ?It is clear that this is not an option. The distance between the slats is taken according to the size of the slate sheet. There are recommendations to start from half a meter, but the sheet has a width of 53 cm. This should be taken into account;
- , before the slate is laid, roof insulation should be made. For this purpose, a roofing material is applied to the crate.
Sometimes joints of sheets of adjacent rows should be sealed with a mounting foam. It should be borne in mind that the sheets of the upper row are laid on the bottom - this ensures a normal flow of water from the roof.
