Durability
The principles behind detailed requirements for fixings, flashings, corrosion, compatibility, and maintenance as described elsewhere in this COP should also be applied to the design and installation of pressed metal tiles.
Exceptions result from the specific differences between tiles and other forms of metal roof cladding, and include the height of laps and specific dimensions of metal shingles and shakes prescribed in this section.
Steel based metal tiles, shakes, and shingles must have hot-dipped galvanised fasteners that are compatible with the base metal and provide a service life equivalent to the durability of the panel.
Panels are fastened to the roof structure by fixing horizontally through the front of the panel; and because the fixings are in shear, they provide wind uplift resistance suitable for very high wind design loads.
