The installation technique of a special profiled sheet used to cover roofs is relatively simple. To master it, it is quite enough to become familiar with some features of the material used, as well as with the basic rules for handling it.
Before you cover the roof with a metal profile with your own hands, you need to carry out a number of preparatory operations of the following nature:
Complicated roofing made of corrugated
The complexity of installation work increases significantly in the case of construction of roofs of complex configuration.
At the initial stage of the preparatory work, you need to choose the type of profile sheet that is suitable for your conditions, which can have the following designs:
Before installing the roof covering, you should be familiar with how to properly choose the amount of overlap between adjacent sheets, which depends on the angle of inclination of the roof itself. In this case, the following relationships are true:
Waterproofing of the roof
Before closing the roof with a metal profile it will be necessary to worry about the arrangement of waterproofing that protects wooden elements of the structure and insulation from the damaging effects of moisture. Waterproofing, which is usually used as a thick polyethylene film, is attached directly between the rafters with small building clips. A small overlap (about 15 cm) is made at the junction points of adjacent strips of film.
Special attention should be paid to the fact that the protective waterproofing film should be stretched with a slight slack (about 2 cm), and between it and the insulation material there should be a small gap of about 2-3 mm.
Special ventilation rails are mounted on top of the waterproofing layer, creating conditions for air circulation in free spaces under the crate and excluding the possibility of accumulation of unwanted moist fumes in this place.
For the installation of metal profile blanks, a special lathing should be used that provides the required strength of the roof structure and withstands its breaking or bending under the influence of wind loads or under heavy snowfall.
Roof pattern made of corrugated
Manufacturers of roofing metal products indicate the main parameters and the procedure for arranging the battens for them in the instructions attached to the product. That is why before starting work it is recommended to carefully read all the instructions on how to use the purchased material.
Fastening the end strips
After the installation of the batten is completed, a special end plate is nailed onto its ramp section, width which should correspond to the height of the selected roof profile.
Thus, the overall composition of the roof covering, the final layer of which is the metal profile itself, usually looks like this:
Roof cake made of corrugated
Rules for the installation of corrugated
Laying roofing sheets with an appropriate angle of overlap should be carried out starting from the bottom corner of the blood. It is necessary to observe the following sequence of installation:
To the crate, sheets are attached through each second wave.
In the course of work, it should always be remembered that it is allowed to move only along finally fixed workpieces. In this case, the feet should be placed in the deepening of the waves, based on the elements of the sheathing.
The amount of overlap is important
