Skylight Contractor in Santa Rosa, CA
Mario Contreras Roofing is a skylight contractor in Santa Rosa serving homeowners throughout Sonoma County with over 20 years of local roofing experience. We handle skylight installation on existing homes and new construction, along with skylight repairs when older units start leaking or the flashing around them fails.
A skylight that is not properly integrated into the roof system will leak — it is that simple. Whether you are in Fountaingrove, Rincon Valley, Bennett Valley, Skyhawk, or Larkfield-Wikiup, we flash and seal every skylight the right way so it stays watertight through Santa Rosa winters and holds up to years of summer UV exposure. We also coordinate skylight work with roof repair and roof replacement projects when they are part of the same job.
- 20+ Years installing and repairing skylights on homes across Santa Rosa and Sonoma County.
- Lic. Fully licensed and insured in California on every job we take.
- ES/EN Bilingual service in English and Spanish for Santa Rosa homeowners.
Why Santa Rosa Homeowners Choose Mario Contreras Roofing for Skylights
Most skylight leaks we see come from failed flashing, cracked seals at the curb, or old units that have simply aged out. The roofing around the skylight opening matters just as much as the unit itself. We treat every skylight installation and repair as a roofing project — not just a fixture swap — because that is what it takes to do it right.

Skylight Installation and Repair Across Santa Rosa
We install and repair skylights throughout Santa Rosa — in older bungalows near downtown and Montgomery Village, updated homes in Bennett Valley and Rincon Valley, and newer construction in Fountaingrove and Skyhawk. For new installations, we cut the opening, frame it properly, install the unit, and flash everything into the existing roofing. For repairs, we inspect the full opening and surrounding roof surface to find the exact source of the leak before recommending any work.
When a skylight project is part of a larger roof replacement or roof repair, we coordinate the work so it is all done at once with no gaps in the schedule.

Skylight Questions from Santa Rosa Homeowners
Common questions we hear from homeowners in Santa Rosa before getting started with skylight work.
Why is my skylight leaking?
Most skylight leaks come from failed flashing around the frame, a cracked or deteriorated seal at the curb, or a unit that has aged past its useful life. We inspect the opening and the surrounding roof surface to find the exact cause before recommending any work — sometimes it is a simple reseal, and sometimes the unit needs to be replaced entirely.
Can you install a skylight in an existing roof?
Yes. Our skylight installation service covers both existing roofs and new construction. We cut the opening, frame it properly, install the unit, and flash everything into the existing roofing surface so there is no way for water to get in.
Do you handle skylights in other parts of Sonoma County?
Yes. Mario Contreras Roofing is based in Santa Rosa and serves all of Sonoma County. We work regularly in Healdsburg, Windsor, Sebastopol, and Sonoma. Call us at (707) 540-2592 to confirm we cover your area.
