Tile Roof Calculator

Concrete & Clay Tile Quantity & Cost

The Tile Roof Calculator returns tile count, weight per square, fastener count, and total cost for concrete or clay tile roofs. Select profile (Spanish S-tile, flat shake, mission barrel) and enter your roof area; the tool returns tile count using typical coverage of 90 tiles per square. Tile roofs weigh 600-1,200 lbs per square and require engineered framing — heavier than asphalt by 4-6x. Tile lasts 50-100 years and qualifies for hail and fire discounts on home insurance.
