A roof replacement is more than pulling off old shingles. At Portola Valley 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.
Our Portola Valley replacement crews install GAF, Owens Corning, and CertainTeed shingles. We carry manufacturer certifications from all three, meaning factory-trained installers and access to the best warranty programs available. We help you choose based on budget, color, and warranty goals.
Our Roof Replacement Process
Free Roof Inspection
Before we quote anything, we inspect everything. A 30-45 minute walkthrough of your entire roofing system. If you only need a repair, we tell you. If replacement makes more sense, we explain why.
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.
Inspection & Cleanup
Three magnetic nail sweeps, during tear-off, after install, before we leave. Dump trailer hauled off. Job site clean. You approve the work and we register your manufacturer warranty on the spot.
