The roof is one of the two most vulnerable parts of a building when it comes to water infiltration. In general, roofing materials are waterproof, but this is not enough. A roof is subject to intense wear and tear and it is necessary to add supplementary waterproofing materials.
They are either applied as a protective coating over the roof or installed under it, as part of the roof frame.
