Flashing, Chimney & Skylight Repair in Santa Rosa, CA · Metal Roofing Alliance Member

On the Santa Rosa Plain below the Mayacamas, water finds every gap. A chimney on a McDonald Avenue Victorian, a skylight over a West End bungalow kitchen, or a valley flashing on a Bennett Valley ranch roof all take the same beating when an atmospheric river parks over Sonoma County and dumps inches in a day. That is why Flashing, Chimney & Skylight Repair in Santa Rosa is the work we get called for most after a storm. We rebuild the metal transitions at chimneys, skylights, valleys, and wall intersections, and we bend the pieces in-house so the fit is tight, not close. If water is already inside, start with our metal roof leak repair page and we will trace it to the source before anything gets sealed.

Why Flashing Fails First on Santa Rosa Roofs

Flashing is the folded metal that sheds water where the roof plane meets something vertical or something cut into it. On Santa Rosa homes it is the number one leak point, ahead of panel seams and fasteners. The failure is rarely dramatic. It is a lifted counterflashing on a Coffey Park rebuild, cracked sealant behind a chimney on a Fountaingrove hillside home, or a skylight curb on a Rincon Valley ranch that was flashed with caulk and hope. Ten dry months hide it, then the first real storm in November finds it.

• Chimney counterflashing pulls away from masonry as the two materials expand at different rates through hot summers.
• Skylight curbs on 1970s and 1980s homes in Montgomery Village leak at the corner where the curb meets the deck.
• Valley flashing on Victorian and Queen Anne roofs around Railroad Square rusts through where debris sits and holds moisture.
• Step flashing at sidewalls on Craftsman bungalows in the West End separates when the siding or stucco above it settles.
• Barn and winery roofs across the Russian River Valley and Dry Creek lose their wall flashings to wind-driven rain and decades of sun.

Every one of these is fixable without tearing off a roof, provided someone gets up there and looks before the damage spreads into sheathing and ceilings.

Key info: After the 2017 Tubbs Fire, many Coffey Park and Fountaingrove rebuilds went up with Class A metal roofs and new chimneys. Where the chimney flashing was detailed quickly during the rebuild rush, we find the same corner leaks five to seven winters later. A $600 flashing repair beats a $4,000 ceiling and insulation job every time.

For the code side of chimney and roof penetrations, the City of Santa Rosa building department is the authority to check with, and we pull permits when the scope calls for it: City of Santa Rosa official site.

How We Rebuild Chimney and Skylight Flashing in Santa Rosa

We do not chase leaks with a caulk gun. We open the transition, see what is actually behind it, and rebuild it with metal that will still be there in twenty years. On a typical Santa Rosa job the sequence runs like this, and it holds whether we are on a Petaluma hilltop or a Sonoma Valley farmhouse.

1. We inspect from the roof and, when needed, from the attic to confirm where the water is entering.
2. We remove the old flashing, failed sealant, and any rotted decking or sheathing underneath.
3. We measure the penetration and bend new flashing in-house to match the chimney, curb, or wall exactly.
4. We install base flashing, step or counterflashing, and a proper cap or cricket on the uphill side.
5. We seal the correct laps with compatible sealant and fasten with the right screws for the panel type.
6. We water-test the repair and photograph it before we leave.

If the surrounding panels are also tired, we will tell you honestly whether a targeted repair still makes sense or whether the roof is at the point where our metal roof repair scope should widen.

Key info: A Sebastopol farmhouse with a masonry chimney and a standing seam roof had been patched three times by others. We pulled the old counterflashing, found the masonry shoulder was out of level, and bent a new two-piece counterflashing with a slip joint that lets the metal move. It has been dry through two winters of Russian River storms.

Flashing Repair Approaches We Use

Not every leak needs the same fix. The right approach depends on the roof material, the penetration type, and how much movement the assembly sees. Here is how we match method to problem.

We choose the least invasive approach that will actually hold, and we say so up front if a cheap patch is only buying a season.

Flashing, Chimney & Skylight Repair Cost in Santa Rosa: What to Expect

Most chimney and skylight flashing repairs in Santa Rosa start around $600 and go up from there. That starting figure covers a straightforward counterflashing replacement or a small skylight reseal on an accessible roof. What moves the number is scope, not salesmanship: how high and how steep the roof is, whether the chimney is masonry or metal, how many penetrations are involved, and whether rotted decking has to come out. A Fountaingrove hillside home with a steep pitch and a tall masonry chimney costs more to access than a flat ranch roof in Bennett Valley, and the price reflects that.

Two or three estimates is the right move on anything beyond a small repair. It keeps pricing honest and gives you a second opinion on whether the leak is really at the flashing or somewhere else. Our full pricing overview lays out how we build a number, and we will walk the roof with you if you want to see what we see.

Hiring a Metal Roofing Contractor Near Santa Rosa: What to Check

Flashing work is small enough that almost anyone will quote it and detailed enough that not everyone gets it right. Before you hire, check that the contractor holds a valid California license and carries liability and workers compensation insurance. Ask for the license number and verify it with the state. Get at least two written estimates that describe the repair in specifics, not just a lump sum.

• Ask for references from Santa Rosa jobs and call them, especially anyone whose repair has been through a full winter.
• Confirm who pulls the permit when one is required, and check with the city building department on historic district or HOA design review if your home sits in a covered area.
• Make sure the written scope names the flashing components being replaced, not just "reseal."
• Ask whether the contractor fabricates flashing in-house or buys stock pieces that may not fit your chimney.

If a quote is vague or the contractor dodges the insurance question, keep looking. You can reach us through our contact page and we will tell you straight whether the job is a repair or something bigger.
