Company Profile
Bay Valley Roofing & Solar is a family-owned and operated Concord business founded in 1989 by Raul Diaz.

As a GAF President’s Club Member and Diamond Certified contractor, we provide extensive warranties on our work. What truly sets us apart is our flexible approach; we offer three distinct service plans because we understand some Concord homeowners have experience or want to manage parts of a project themselves.

Q&A
As a Concord homeowner, how do you handle common roof leaks and gutter overflows after our rainy season?
We address these common local issues directly. For leaks, we perform a thorough inspection to find the exact source—often around flashing, vents, or damaged shingles—and provide a precise repair plan. For gutter overflows, we assess your system for proper pitch, clear blockages, and recommend solutions like larger gutters or added downspouts to handle Contra Costa's rainfall. Our goal is a fix that lasts, not a temporary patch.
What are the benefits of combining a new roof installation with solar shingles in the Bay Area?
Installing a new roof and solar shingles together is a smart, efficient choice for Bay Area homes. It ensures your solar mounting system integrates seamlessly with a roof designed to support it for decades. As a GAF-certified installer, we can coordinate both projects under a single warranty and timeline, minimizing disruption. This approach also maximizes your energy savings from day one on your new roof.
You mention flexible service plans. What does that mean for my roof repair or solar installation project?
It means you have choices. We offer three plans to match your involvement level. We can manage the entire project from design to completion, which most homeowners prefer. Alternatively, if you're experienced or budget-conscious, we can handle specific complex aspects—like the solar electrical tie-in or structural repairs—while you manage other tasks. This flexibility, unique in our area, ensures you get the exact support you need.
