For homes in our area, a full replacement starts with a thorough inspection to assess the decking and underlayment. We then carefully remove the old materials, address any underlying issues like deteriorated underlayment—a common local problem—and install a new, high-quality roof system. This includes proper ventilation, durable shingles or tiles rated for coastal weather, and critically, the correct installation of new flashing to prevent leaks at chimneys and vents, which are frequent trouble spots in the Bay Area.

Lifting or failed flashing is a primary cause of leaks in San Francisco due to wind and temperature shifts. We address this by first removing the compromised flashing and inspecting the surrounding roof structure. We then fabricate and install new, code-compliant flashing, often using corrosion-resistant metals, and integrate it seamlessly with new underlayment and shingles. Proper sealing and secure fastening are key to ensuring it withstands our unique coastal conditions and protects your home long-term.

The need for repair versus replacement depends on the roof's age, material condition, and extent of damage. Isolated issues like a few missing shingles or a small leak often warrant a repair. However, widespread granule loss, multiple leaks, sagging, or significant underlayment failure typically indicate a replacement is more cost-effective. Our 30+ years of experience in the Bay Area allows us to provide an honest assessment, explaining the pros and cons of each option for your specific situation without pressure.
