Is a Tile Roof a Valuable Type of Insulation?

Tile roofs are good insulators. The combined effect of the roof tiles, decking, and the “air space” between the tiles allows for better air circulation and thereby reduces direct heat transfer, resulting in lower air conditioning costs in the summer and a decrease in the formation of ice dams in the winter. Won’t my building have to be a lot stronger and more costly to support a tile roof? Most commercial or quality residential structures require little or no additional bracing. Additional costs, if any, to support tiles are usually an extremely small portion of the total project. Clay and concrete roof tiles have Class A fire ratings, meaning they are non-combustible. And, both types of roof assemblies maintain their Class A fire ratings throughout their lifecycles. No additional or periodic treatments are required. In addition, buildings with Class A rated tile systems are eligible for the lowest fire insurance rates.
