Frequently asked questions

Questions about tile roof installation.

Why does tile roofing require structural review?+

Clay and concrete tiles are heavier than many roof materials, so the structure must be able to support the system.

What protects the roof beneath the tiles?+

Underlayment, flashing, valleys, and roof-system details provide critical water protection beneath the tile surface.

Can roof tiles be walked on?+

Walking on tile can crack or displace pieces and should be limited to trained professionals using appropriate methods.

Can one broken tile be replaced later?+

Often, yes, when a compatible profile, size, color, and fastening method remain available.
