Characteristics of metal roofing as a roof
Roof roofing with metal tiles usually does not cause difficulties and is produced in the shortest possible time. The coating has proven itself in the temperature range from -50 to +50 degrees Celsius, which is difficult to overestimate in the Russian climate. At a relatively low price metal roofing is light and durable, fire and environmentally safe.
However, it is sensitive to the influence of corrosive substances, and in the presence of such in the atmosphere it makes sense to use metal tiles made of copper or aluminum with special coatings. A significant drawback is the ban on cutting metal tiles with abrasive wheels - under the influence of high temperature protective layers burn out, and the process of intense corrosion begins.
Roofing: metal roofing
The technology of roofing with metal roofing strongly requires preliminary measurements of the roof - each of its slopes must be a perfectly flat rectangle. It is not difficult to determine this by measuring the diagonals of each slope - they must be equal. If necessary, the defect can be corrected by means of a crate and additional elements.
It should also be remembered that the minimum allowable angle of slope is 14 degrees. If before there was a cover on the roof, it must be dismantled. And although the finish of the roof metal tile is simple, for its high-quality and fast execution, you will need certain tools: a screwdriver, a tape measure, a hammer, a marker and a long rack. For cutting roofing sheets, you can recommend electric jigsaw, electric scissors or a disk saw. Hand-cutting tools are also suitable.
It should be noted that as a roof, metal roofing, the flooring instruction of which is given below, is unrivaled. Works on its installation can be performed independently. Making roofing work, metal should be carefully guarded against mechanical damage, completely unacceptable scratches on the surface.
How to cover the roof with metal tile yourself?
And now we will look at the step-by-step instructions, the result of work on which should be the design of the roof made of metal. To protect the insulation from the condensate from the outside, rails of waterproofing with a slip of 20 cm are rolled horizontally in the horizontal direction.
The uncoiling begins from the eaves, individual sheets overlap with a overlap of 15 cm. There are many kinds of protective films, and in order to avoid mistakes in their applicationto study the instructions attached to them. Along the rafters over the waterproofing, blocks of 50x50 mm section are nailed, to which the boards of the crate are fixed in a horizontal direction.
Then between the rafters of the gates, the insulation plates are placed, leaving a gap to the film of 20 mm. On the rafters, a vapor barrier film is fixed from the inner surface, the linens being lapped and joined together by adhesive tape.
The material of the interior decoration of the room is fixed on top of the film. On made earlier the crate is laid metal, and the most attention should be paid to the internal joints of ramps( valley).The first sheet should be leveled at the end of the roof so that the drift with respect to the eaves should be 40 mm, after which it is fastened by the self-cutter at the ridge.
When assembling from right to left, the next sheet is overlapped by the previous one, and they are fastened together by a self-tapping screw on the crest of the wave. The third sheet is attached to the second sheet in the same way, after which they are all aligned on the cornice. The lower part of the sheet is attached to the soles of the waves by screws through one. The remaining rows of screws are staggered in relation to the bottom row.
