All Gerard® roof products are manufactured from alu-zinc steel which have shown in tests to last 6-9 times longer than ordinary galvanised steel roofing products. This is achieved by protecting the steel core with zinc, which is itself protected by an aluminium barrier. As a pioneer of using alu-zinc steel, Gerard® has unrivaled experience in long lasting steel roof tile manufacture.

Other roof materials can help fire to spread. Clay and concrete tiles can both allow embers between the tiles (so a fire outside can set light to the inside of your house) and tranmit heat through the tile. Likewise, bitumen roofs are not as fire resistant as Gerard.
