Common Questions

Roofing Questions,
Honest Answers

Questions San Jose homeowners ask us most. Don't see yours? Just ask.

Common signs include active leaks, damaged or missing shingles, sagging rooflines, visible daylight in the attic, or simply a roof that's 20+ years old. A Keith Roofing inspection will tell you exactly where you stand — and whether a repair will buy you time or a full replacement is the better investment.
It depends on the material. Asphalt shingles typically last 20–30 years in the San Jose climate, concrete and clay tile can last 50+ years, metal roofing 40–60 years, and flat TPO or EPDM systems 20–30 years with proper maintenance. We'll walk you through what makes sense for your home and how long to expect it to last.
San Jose's Mediterranean climate — hot dry summers and mild wet winters — is well-suited to concrete tile, clay tile, architectural asphalt shingles, and metal. Each has trade-offs around cost, weight, and aesthetics. We'll walk you through what makes sense for your home during the estimate.
