The composition includes cellulose fibers impregnated with bitumen. The top is covered with polymer paint. It is more often used for garages, outbuildings and baths. It is mounted at an angle of 6 degrees, attached to the crate with special nails. The service life is about 40 years.
Low cost can be attributed to advantages. If all installation rules are observed, it can withstand a load of up to 950 kg. It is easy to cut a sheet with a manual hacksaw and no soundproofing device is required.
Disadvantages include flammability at higher temperatures. The surface of the ondulin can be covered with moss and bloom in shady places.
Slate
It has the lowest cost. The service life is about 30-40 years. The composition includes portland cement and asbestos. It is made in the form of waves and weighs up to 15 kg. It is fastened at an angle of 12-60 degrees with nails, using a rubber lining.
It is recommended to lay roofing material under the slate to protect against moisture.
