Identify the assembly being evaluated
Clay tile is only one part of a roof. The deck, underlayment, gaps, edges, penetrations and adjacent construction also matter when evaluating fire exposure. A statement about the surface material does not establish every aspect of a particular installed roof’s performance. Request documentation for the proposed assembly and its intended conditions.
Check vulnerable details
The Building America Solution Center discusses tile roofs in relation to wind and wildfire, including the significance of openings and other roof details. Use that guidance to develop questions for the designer and installer. Product approval and local requirements still determine what must be built; a general illustration should not be treated as a universal construction detail.
Keep maintenance in the plan
Debris accumulation, broken units and later roof penetrations can change conditions after installation. Include visible roof and gutter observations in the owner’s maintenance record, and have a qualified professional assess damage or alterations. Avoid promising that a tile roof makes a building fireproof. Document the actual assembly, its stated classification and the maintenance responsibilities instead.
