Fast, Reliable Roof Replacement Across Danville
Roof replacement in Danville usually means one thing: the underlayment under your tile or shingles has given up long before the visible roof did. A full tear-off and re-roof in Danville typically runs from $18,000 to $45,000 depending on roof size, pitch, and material. You’ll get a written price line-by-line before a single shingle comes off. If you’re in Greenbrook, Sycamore, or anywhere else in Danville and water is finding its way inside, call (831) 228-3330 for a free estimate.
Why Birchbark Roofing San Francisco Is Danville’s Preferred Roof Replacement Company
Danville homeowners call us because we treat a roof tear-off like work happening at our own house. Shoe covers at the door. Drop cloths through the hallway. A clean-up photo sent before the crew pulls out of the driveway. It’s the kind of care that matters when you have kids’ toys in the yard and a dog who’s already nervous about the noise.
Erik Lindgren runs our crews, and he’s been on enough Danville tile roofs to know that what looks like a simple leak is often something bigger underneath. We’re part of the Cedarwell family of independent local roofing businesses, and every job carries the 365-Day Done Right Promise. If it isn’t right, we make it right. That’s stamped on the paperwork, not just said at the door.
We coordinate scheduling from our San Francisco Bay Area office, with crews serving Danville directly. A live person answers the phone 24/7, so you’re never waiting on a callback when water is coming through the ceiling.

Roof Installation in Danville
Roof installation in Danville often starts with a question: what’s actually under the tile or shingles you already have? On homes built in the 1960s through the 1980s, the answer is frequently dry-rotted plywood sheathing and felt underlayment that has turned to dust. We don’t install over that. We open it up, show you what we found, and get written approval before replacing any structure.
Underlayment and Decking First
Before any new roof goes on, we inspect what’s underneath. In Danville’s Mediterranean and ranch homes, that means checking valleys, dormers, and chimney flashings where decades of Diablo Valley sun have done their worst. If the decking is rotted, replacing it is part of the job, priced and approved in writing.
Full System Replacement
A proper installation means new underlayment, new flashing, new ventilation, and the roofing material itself. We work with GAF, CertainTeed, and Tamko architectural shingles, and with matching clay and concrete tile for Danville’s upscale aesthetic. The goal is a roof that looks like it belongs on the house and keeps water out for decades.
Roof Replacement Contractor in Danville
When you hire a roof replacement contractor in Danville, you want someone who has opened up enough of these roofs to know what’s waiting. That’s us. On a Mediterranean home in Greenbrook, our tech opened a leaking valley and found the original 1980s felt underlayment crumbling to dust beneath the clay tile. We replaced the entire underlayment, added ice and water shield along the eaves, and reinstalled the tile over new high-temp synthetic underlayment, stopping the leak before it rotted the decking.
Complex Rooflines, Handled Carefully
Danville homes have complicated roofs. Multiple valleys, dormers, chimney penetrations, and steep pitches. Each transition point is a place water tries to get in. We flash every one of them properly, using the materials specified for the roof type and the exposure.
Written Price, Approved Before Work Starts
You’ll see your exact number in writing before any work begins. Not an estimate that floats after the first tear-off reveals surprises. If we find hidden damage, we stop, show you photos, and get your sign-off on the change before touching it. That’s the Birchbark way.
Trusted Brands We Service in Danville
We work with materials from GAF, CertainTeed, Tamko, IKO, Atlas, Owens Corning, and Boral. For Danville’s tile-heavy luxury market, Boral clay and concrete tile and high-end architectural composition shingles are the most common choices, and we keep strong relationships with local suppliers so lead times stay short. Need a specific color match for a Mediterranean in Greenbrook? We’ll find it. The point is getting a roof that looks right on your house and performs for the long haul.

AfterCommon Roof Replacement Problems We See in Danville Homes
- Failed 1980s felt underlayment under tile roofs in Greenbrook and Sycamore. Tiles still look intact, so homeowners think the roof is fine. Water is getting through the underlayment and rotting the decking underneath. This almost always means a full re-roof, not a tile patch job.
- Poorly flashed valleys and dormers on Mediterranean and ranch homes. Wind-driven rain pushes water sideways into the transitions, and old flashing simply isn’t up to it. These leaks are intermittent, which makes them hard to diagnose and easy to ignore until the damage is done.
- UV-degraded granule adhesion on south-facing slopes. Danville’s intense summer sun bakes architectural shingles until the granules start sloughing off. You’ll see the granules in your gutters and bald spots on the shingles.
- Dry-rotted plywood sheathing. Once water gets past failed underlayment or flashing, it sits against the plywood and rots it. By the time you see the ceiling stain, the sheathing often needs replacement too.
Pricing for Roof Replacement in Danville, CA
What you’ll pay depends on what’s under the existing roof and what you’re putting back on. A straight composition shingle replacement on a 2,000 – 3,000 square foot Danville ranch typically runs $18,000 to $28,000. Larger estate homes with clay or concrete tile and complex valleys run $35,000 to $55,000. If the sheathing needs replacing, that adds $3 to $5 per square foot, priced in writing before we proceed. You’ll get a free estimate with line-item pricing. Call (831) 228-3330 to schedule one.

FAQs About Roof Replacement in Danville
If the tiles are intact but you’re getting leaks, the problem is almost certainly the underlayment, which means a full re-roof. In Danville’s Greenbrook and Sycamore neighborhoods, the original 1980s felt underlayment breaks down long before the tile does, so replacing a few tiles will not stop the water. We’ll open up a section, show you the condition of the underlayment, and recommend based on what we actually see. Call (831) 228-3330 for an inspection.
We tear off down to the decking, inspect every valley and dormer transition, replace any rotted sheathing, install new high-temp underlayment and flashing, and then install the new roof. On complex Danville rooflines, we coordinate the crew schedule around your family’s routines and keep the site clean throughout. The written price includes all of it before we start, and any hidden damage gets priced and approved in writing before we touch it.
Yes. We work with Boral clay and concrete tile in colors and profiles that match the original Mediterranean look, and we have experience matching existing tile on Danville homes. The goal is a roof that looks like it was always there. If you want to keep the original tile and just replace the underlayment, we can do that too, provided the tile is still sound. Call (831) 228-3330 to discuss your roof.
Most leaks in Danville ranch homes trace back to flashing failures at valleys, dormers, or chimney penetrations, and to shingle granule loss on sun-blasted south-facing slopes. Once the granules go, the asphalt underneath breaks down quickly. If you’re seeing stains on the ceiling after wind-driven rain, call (831) 228-3330 and we’ll find the exact source before it rots the decking.
The biggest difference is whether the quote accounts for what’s under the roof. Some crews price for a simple overlay or a tear-off without factoring in decking replacement, underlayment upgrades, or proper flashing work. Danville’s older homes frequently need all of that once the roof comes off. Our written price includes the full scope, with allowances written in for likely hidden damage, so the number you approve is the number that stands. Call (831) 228-3330 for a free estimate.
If your Danville roof is leaking, or you’re planning ahead for a replacement, call (831) 228-3330. You’ll get a live person, a free estimate, and a written price before any work starts. Erik Lindgren and the Birchbark Roofing San Francisco team will treat your home like our own.
