Wavy sheets, as a rule, are more popular as a roof covering material, since they are simpler to install and reliable during the entire operational period, and the amount of wood required for sheathing using slate will be needed less. The standard angle of inclination of the slate roof is 25 – 33 degrees.
When dealing with how to block the roof with your own hands, using asbestos cement sheets, you should follow the following rules:
- corrugated asbestos cement sheets must be mounted on a crate, the basis of which is made up of wooden bars with a cross section of 50 × 50 millimeters, keeping the rafter step equal to no more than 1.2 meters. Another variant of the device of the batten is a section of 50 × 60 millimeters with a step of up to 1.5 meters;
- crate boards must have a cross section of 120 × 40 millimeters or poles having a diameter of 70 – 80 millimeters. The step distance between the crate bars should not be more than 525 millimeters;
- overlapping the roof of the veranda requires reducing the slope of the slate roof to 10 degrees, but in this case it will be necessary to seal the transverse and longitudinal sheet joints;
