It happens that people making the roof do not know the correct methodology for this process. And in fact, despite the huge variety of roofing materials, answering the question of how to properly cover the roof is not easy. But still try.
You need to know that each material has its own method of application. Any of them has its drawbacks and its advantages. In this regard, choosing roofing material, you can’t rush. It is necessary to carefully study each of them, and make a choice only when the full picture is clear. Today, slate, ondulin, corrugated board and metal tile are in great demand.
Metal today is a very popular roofing material, which has a large number of advantages. This is, first of all, durability - the tiled roof serves up to 50 years. Secondly, it is the lightest roofing material. And thirdly, the metal tile has a very attractive appearance and a rather low price. Learn how to cover the roof.
It’s enough just to make a roof with your own hands, without attracting professionals. Now we will consider specifically how to cover the roof with metal tiles. It consists of a galvanized steel sheet of 0.4-0.7 mm, which is coated on both sides with a protective polymer coating. The metal tile is absolutely indispensable when coating roofs with complex structures, in addition, it is very reliable and does not need repair costs, and this is economically profitable.
Before you begin, you need to purchase a sufficient number of sheets. Take a measurement of the roof, while taking into account that it is necessary that the sheet of metal was 4 cm longer than the roof, it itself must be completely flat. If irregularities cannot be eliminated, then the metal tile must be laid so that the line of overhang of the sheets coincides with the edge of the crate.
Installation of the roof roof begins with the rafter system. A screed of the bearing walls is made, then waterproofing - the rafters are covered with a waterproofing film. To do this, rolls of waterproofing roll out on the rafters. The first layer is laid out so that it hangs from the cornice by 20 mm, and all subsequent layers are overlapped (150 mm).
We will consider further how to cover the roof. Be sure to remember about insulation and vapor barrier. Thermal insulation material is mounted between the rafters. Depending on the type of film, ventilation gaps are sometimes required between the insulation boards. The vapor barrier canvases are fastened with a construction stapler, they must be arranged crosswise. They must be sealed tightly.
At the next stage, the installation of the crate is done, on which, in fact, the sheets of metal tile are attached. Usually, the crate is made of wooden boards treated with an antiseptic. On top of the waterproofing layer to the rafters from the ridge to the cornice, the bars are vertically attached to which the crate is horizontally nailed. Depending on the type of metal tile, the space between the planks of the crate is laid out either as a solid sheet, or with gaps.
And finally, we fasten the sheets of metal. The answer to the question of how to cover the roof with a metal tile depends entirely on its type. If the roof is hipped, then you need to cover it from the highest point down, and if gable - from the end.
The first sheet is laid in such a way that a 4 cm extension is obtained from the cornice, after which it is fixed at the ridge. The next sheet is placed on the first lap and then aligned parallel to the cornice.
Now it’s obvious that this is a simple job, it’s enough to know the algorithm of actions and buy the required materials. In addition, you can learn how to cover the roof with metal tiles by reading the instructions that came with the material.
