Chapter 01 — What a tile roof actually is
The tile is the wear layer.
The underlayment is the roof.
Tile dominates South Florida roofing for good reasons: it shrugs off UV and salt air better than almost any other covering, it is standard or required in a lot of developments and HOA documents, and it carries the longest realistic lifespan of the common systems.
But it is not one product. Tile splits hard along concrete versus clay, along profile, and along fastening method, and those three choices drive real differences in weight, cost, breakage risk and service life. Treat tile as a structural decision rather than a material selection and most of the expensive surprises disappear.
The part that decides how long the roof lasts is the layer nobody sees. Tile is largely a wear and wind-uplift layer; the self-adhered underlayment beneath it is what actually keeps water out. That is why a tile roof commonly needs a full underlayment replacement long before the tile stock is worn out — and why a roof can leak with every tile on it intact.

LB per square
Clay commonly runs 600 to 900 pounds per square; concrete is heavier at roughly 900 to 1,100, partly because it absorbs water over its service life.
LB per square carried
Florida truss systems engineered for tile are commonly designed around this dead-load range. A frame built for shingle usually is not.
Manufacturer ratings
Concrete is typically warrantied in the 40 to 50 year range; clay is commonly rated 50 years and up with proper maintenance.
