The h2o repelled from the roof all through a rainstorm is probably damaging for the constructing which the roof guards. If it operates down the walls, it could seep in to the mortar or via panels. If it lies round the foundations it may well lead to seepage to the interior, mounting damp or dry rot.

More elaborate devices may perhaps perform most of these functions: make electrical power, Recuperate thermal Power, and also work as a roof covering.

Considering the fact that then, quite a few forms of metal roofing are actually created.
