A tile roof isn't a cosmetic upgrade — it's a system. If deck, underlayment, flashing, fasteners, and ventilation are handled correctly, tile protects a PA home for decades.
Weighing tile? The right questions come up fast. Is it worth the upfront cost? Can the house even carry the weight? Will it handle ice, snow, wind, and freeze-thaw around Pittsburgh, Erie, and Sharon?
Tile can be a 50-year decision if the system underneath is right. If a contractor cuts corners under the tile, the roof gives you trouble long before the tile itself wears out.
Clay or concrete
Clay is the classic — long life, color that doesn't fade, higher cost, heavier and more brittle. Concrete is more affordable, still very durable, available in more profiles. In PA, both work if flashing and underlayment are done right.
Structure comes first
Tile is heavy — 600 to 1,100+ pounds per square. Not every house can carry that without reinforcement. A structural review before tear-off is not optional.
Underlayment does the waterproofing
The tile sheds most water. The underlayment stops what gets past. Use a high-quality synthetic or self-adhered membrane rated for the pitch, and don't skimp at valleys, eaves, and penetrations.
Flashing, fasteners, and layout
Flashing separates a 40-year roof from a 10-year callback. Fastener spec changes with pitch, snow load, and tile profile. Layout has to work with the exact tile — dry-run before you fasten anything.
PA code, ventilation, cost, and timeline
Confirm your municipality's permit and inspection requirements. Balance intake and exhaust ventilation so heat and moisture leave the attic. Installed cost typically lands $18-$35 per square foot depending on material and complexity. Plan on 1-3 weeks for most homes.
