✨ Based on 2026 local roofing labor rates for Local Area
San Jose sits in a Mediterranean climate (Köppen: Csa).
Dry, hot summers. Mild, wet winters. Long stretches without moisture. Here’s what actually damages roofs here: UV breakdown during long dry seasons. Thermal expansion cracking older shingles. First-rain leaks because debris dries and hardens. Moss forming on shaded north-facing sides. Occasional wind gusts over the hills. Roofs here fail slowly… then leak all at once.
— Advertised: 25 years
— Reality: 15–20 years
Dry heat ages them early.
— Reality: 20–28 years
— Tile lasts: 40–60 years
— Underlayment: 20–30 years (the real weak point)
— Actual: 40–60 years
Great durability. Higher price.
Bay Area labor rates hit hard. Expect higher numbers than national averages.

Low bids in San Jose = uninsured labor or reused flashing. Red flags.
California roofing is strict.
You MUST have a CSLB C-39 Roofing License to work legally.
San Jose also requires:
Permit for all re-roofs
Proper ventilation for energy code
City inspection after underlayment
Skip the permit, and SJ will catch it — trust me.
100°F heat on a roof deck fries you and your shingles
Wrong ventilation cooks the attic
Tile underlayment replacement isn't DIY-friendly
Insurance will deny claims instantly
I’ve seen more DIY roofs fall apart after the first rain than I can count.
