Roof Replacement | East Bay Roofers

A full roof replacement begins with a thorough inspection of your existing roofline. Our crew sets up scaffolding and safety harnesses before stripping the old, weathered shingles down to the roof deck. We tear off damaged felt, underlayment, and any rotted OSB or plywood sheathing, hauling all debris to a dumpster for proper disposal.

5 Key Highlights — Roof Replacement

Complete tear-off and disposal — we strip every layer of old shingles, deteriorated underlayment, and compromised flashing down to the roof deck, hauling all debris for proper disposal
Full decking inspection — every roof replacement includes a thorough check of your OSB or plywood sheathing; rotted or warped boards get replaced before new materials go down
Premium shingle options — choose from architectural, impact-resistant, or designer shingles rated for your climate, including GAF Timberline, Owens Corning Duration, and CertainTeed Landmark
Proper flashing and ridge cap installation — flashing around chimneys, vents, and valleys gets sealed and secured; ridge cap shingles are hand-nailed for a watertight finish at every peak
Manufacturer and workmanship warranties — your new roof installation comes backed by both the shingle manufacturer warranty and our own labor guarantee

Signs You Need Roof Replacement

Shingles are curling, cracking, or missing — once the granule coating wears off, the asphalt layer bakes and becomes brittle, leaving your roof deck exposed to water intrusion
Granule buildup in your gutters — heavy granule deposits in gutters or at downspout bases means your shingles are nearing end of service life, accelerating heat absorption and UV damage
Sagging roof decking — a roof deck that dips between rafters signals prolonged moisture damage to the OSB or plywood sheathing, which cannot support a new shingle layer safely
Flashing failures around penetrations — corroded or pulled-away flashing at chimneys, skylights, and vents causes repeated leaks despite repairs, pointing to systemic failure
Roof age exceeds 20 years — standard architectural shingles carry a 20-25 year functional lifespan; UV radiation and heat cycles degrade shingles faster in hot climates
