Frequently Asked Questions
Do you work directly with general contractors?
Yes — we've worked with Peninsula GCs and builders since 2002. We understand scheduling dependencies, coordinate with framers, and show up when we say we will so the next trade isn't waiting on us.
What roofing systems do you install on new construction?
We install composition shingle, architectural shingle, concrete tile, clay tile, slate, and flat roofing systems on new residential and commercial builds. We work to the architect's spec and local code.
How early in the build process should we schedule roofing?
Reach out once framing is substantially complete. Lead times vary by season — Bay Area roofing books up faster in spring and early summer. Earlier is better.
Do you handle permit coordination on new builds?
Yes. We handle all roofing-related permits and ensure the install is ready for inspection. We know San Mateo County and Santa Clara County building requirements well.
Can you match a specific roofing spec from an architect or HOA?
Absolutely. We work from architectural plans and can source specific approved materials. If you have an HOA requirement or design spec, share it with us upfront and we'll confirm we can meet it before quoting.
