Roof Repair, Replacement, and More for Petaluma Homes
Petaluma's housing stock ranges from century-old Victorians in the downtown historic district to mid-century homes in the Westside neighborhoods and newer construction east of Highway 101. Each era of home comes with its own roofing challenges — older homes often have multiple layers of material and aging flashings, while newer homes can have installation issues that show up years later.
Whatever the age or style of your Petaluma home, Mario Contreras Roofing handles the work with the same attention to detail and honest approach on every job.
Start with what your roof needs
A property’s address or age alone does not tell us whether it needs a repair or a new roof. Tell us about leaks, earlier work, and the material if you know it. We assess the condition and explain the proposed work so you can make a decision with useful information.
- Leak diagnosis and repair for new or returning water entry.
- Roof replacement when a wider project makes sense.
- Roof inspections to understand the condition before deciding.
- Commercial roofing with access and building use in mind.
- Gutters and skylights connected to the roof system.
