questions answered
More questions? Call (707) 540-2592. We’re happy to talk through your project.
Can you repair my roof instead of replacing it?
Often, a targeted repair is worth considering. The answer depends on the source of the problem and the condition around it. We assess the roof and explain when repair makes sense and when replacement deserves a closer look.
Do you work outside Santa Rosa?
Yes. We serve Sonoma County, including Windsor, Rohnert Park, and Petaluma. See our service areas.
What should I have ready for an estimate?
Your project address, a short description of the problem or project, and any photos you can take safely from the ground. Existing roof paperwork is useful if you have it.
What are your business hours?
Monday–Friday 7am–5pm and Saturday 8am–2pm. Sunday is closed. Call during these hours to discuss urgent leaks and current availability.
Do you offer service in Spanish?
Yes. Hablamos Español. Llámenos al (707) 540-2592 para hablar de su proyecto.
