A roof replacement is more than pulling off old shingles. At San Anselmo Roofing & Maintenance, we do a complete tear-off down to the decking, inspect every board for moisture damage or rot, and build your new roofing system from the deck up. Every layer installed to manufacturer specifications.
A roof system is more than the shingle on top. We install ice and water shield at valleys and penetrations, synthetic underlayment across the full deck, aluminum drip edge, proper starter strip, and ridge vent for balanced attic ventilation. Every layer matters for longevity.
Our Roof Replacement Process
Initial Assessment
We climb up, walk the entire roof, and take photos of everything we find. Shingle condition, flashing, vents, gutters, and signs of moisture damage underneath. You get a full written report, free, no obligation.
Transparent Pricing
You receive a written proposal with material specs, labor breakdown, timeline, and total cost. We price by the square and itemize everything. Compare apples to apples with any other quote.
Professional Crew
Our crews average 8+ years experience each. Tear-off, decking inspection, ice and water shield, underlayment, drip edge, starter strip, field shingles, hip and ridge caps, and ridge vent, installed in the correct sequence per manufacturer requirements.
Warranty Activation
Our project manager inspects the finished roof against the manufacturer checklist. You get a written workmanship warranty from San Anselmo Roofing & Maintenance plus the manufacturer warranty registered directly with GAF, Owens Corning, or CertainTeed.
