GRC Roofing | Roofing Services in Oakland, CA 94603

We see these problems frequently due to our local climate. For lifting flashing, we assess the underlying cause—often improper installation or thermal movement—and re-secure or replace it using methods suited for Oakland's temperature shifts. For deck rot, we remove affected sections, treat the area to prevent mold, and install new, properly ventilated decking. Our 25 years of experience ensure we not only repair the damage but also implement solutions to help prevent recurrence.

Our gutter replacement is a comprehensive service. We safely remove your old, failing gutters and downspouts, inspect the fascia board for any water damage (common if gutters have been leaking), and install a new, correctly sized system. Signs you may need a replacement include persistent leaks, visible sagging or pulling away from the roofline, rust holes, or frequent clogs that cleaning doesn't resolve. Properly functioning gutters are crucial in Oakland to direct water away from your foundation and siding.

Yes, absolutely. Our moisture control and waterproofing services are designed for both new applications and fixing existing failures. For installation, we evaluate the specific drainage needs of your property and apply appropriate membranes or drainage systems. For repairs, we first diagnose the source of the moisture intrusion—whether it's a failed sealant, cracked membrane, or inadequate drainage—and then perform a targeted repair. Our goal is to create a dry, protected space tailored to your home's structure and Oakland's ground conditions.
