What slows a roof replacement down?
What slows a roof down: wet weather in the rainy season, rot under the old roof, back-ordered products, tile or low-slope systems, solar panels to remove and reinstall, and inspection scheduling. Change orders must be written (B&P 7159.6).
How do permits affect the timeline in the East Bay?
Oakland's self-certified Re-Roofing Certificate is requested online and is valid for 180 days (Oakland); other East Bay cities and the two counties set their own processes. In zone 12 cities like Walnut Creek and Livermore, a compliant cool-roof product must be ordered, and tile relays in the Tri-Valley take longer than shingles.
Can I replace a roof in the rainy season?
It's common in the East Bay, just slower. A careful roofer schedules around storms using the NWS forecast; see our rainy-season reroofing guide.
How do I get a schedule for my roof?
For your actual price, request a free written estimate: a licensed roofer measures the roof and prices your exact scope. Also read what to expect on a reroof and our permit guide.
Every roofer we work with is licensed, insured and highly reviewed by Bay Area homeowners.

Why is my roof start date weeks away?
Permits, materials and crew schedules. Ask for the expected start and duration in writing.
Do tile roofs take longer?
Usually; tile is heavier and slower to lift, re-underlay and relay.
