Roofing Contractor in Rohnert Park, CA

Mario Contreras Roofing serves homeowners and business owners in Rohnert Park with the same honest, dependable roofing work we have delivered across Sonoma County for over 20 years. Rohnert Park was largely built out in the 1960s and 70s, which means a significant portion of the housing stock is now at or past the end of its original roof lifespan. We know this market well and we know what roofs in this area need.

Whether you are in the Benicia Park neighborhood, near Sonoma State, or anywhere else in Rohnert Park, we provide roof repair, roof replacement, roof inspections, gutter installation, and more — residential and commercial — with clear pricing and no pressure.

Roof Repair, Replacement, and More for Rohnert Park Homes

Most homes in Rohnert Park were built between 1960 and 1990 as part of the city's planned development. Composition shingle was the standard roofing material for that era and those original systems are now well past their typical 25 to 30 year lifespan. Many homes in the Benicia Park, Canon Manor, and Rancho Cotate areas are prime candidates for a full roof replacement — and if yours has not been replaced yet, an inspection is a smart first step.

We handle everything from straightforward repairs on newer roofs to full tear-off replacements on homes that are long overdue. Whatever your roof needs, we do the work right.

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.
