AfterFast, Reliable Roof Replacement Across Calabasas
Roof replacement in Calabasas runs between $18,000 and $45,000 on average, with Class A fire-rated tile assemblies on large hillside homes at the upper end. Most full tear-offs here take 5 to 10 working days depending on the footprint and what we find under the old roof. If you’re in Calabasas and your insurance carrier just flagged your existing tile roof, call (424) 766-4937 and we’ll walk the property with you. Erik Lindgren and our crews know the canyon wind zones, the HOA review boards, and the county inspection process because we work them every week.
Key Takeaways:
- Calabasas sits entirely in a Very High Fire Hazard Severity Zone, so every replacement must meet Class A fire-rated assembly code
- Hidden OSB decking without fire-resistant underlayment is the most common reason Calabasas homeowners get forced into a full tear-off
- You’ll get a written price in dollars before any work starts, and a 365-Day Done Right Promise on the completed job
Why Birchbark Roofing Is Calabasas’s Preferred Roof Replacement Company
We’ve torn off enough roofs off Parkway Calabasas and Mulholland Highway to know what this market demands. Calabasas homeowners don’t want a sales pitch. They want a written price, a crew that keeps mud off the travertine, and an assembly that their insurance carrier will actually accept. That’s what Birchbark does. Every job starts with a written price before any work begins. Our technicians are background-checked and uniformed, so you know exactly who’s walking through your door and onto your roof. Shoe covers at the door, drop cloths through the hallway, and a photo of the completed clean-up before we leave.
Erik Lindgren has been part of the Cedarwell family of independent roofing businesses since 2000. That means every Calabasas job is held to two standards: our 365-Day Done Right Promise and the Cedarwell Care Promise. If something isn’t right, we make it right. That guarantee is stamped on every roof replacement we do in Calabasas, not whispered as a maybe.
Roof Installation in Calabasas
Roof installation in Calabasas almost always means a full system: tear-off to decking, new underlayment, new tile or shingle profile, new flashing, and new ridge caps. The job isn’t just swapping the surface. In this city, the code requires a Class A fire-rated assembly, and most insurance carriers want the installer to document that assembly in writing before they’ll renew the policy. A typical roof installation in Calabasas runs $20,000 to $40,000 depending on square footage, roof pitch, and the material profile your HOA approves. You’ll see your exact number in writing before we order a single tile.
New Construction Roofing
We do new construction roofs on custom homes going up in the hillside lots off Las Virgenes Road and around The Oaks. New construction means working alongside framers, electricians, and stucco crews, and it starts with a dry-in inspection before anyone covers a wall. We coordinate steel flashing, roof-to-wall interfaces, and valley details with the project architect so the building inspector sees a finished assembly that passes the first time. If the dog needs to stay inside during a remodel, we coordinate the door schedule with you.
Roof Decking Replacement
In Calabasas, decking replacement is almost never optional once we open the roof. We routinely find bare OSB with no fire-resistant layer under it. That decking has to come out, new plywood or OSB goes down, and then a compliant underlayment goes over it. The decking portion alone typically adds $3 to $6 per square foot to a Calabasas roof replacement. We photograph the old decking before it leaves the site, and we photograph the new assembly before the finished roof covers it. That documentation is what your insurance carrier wants to see.
Roof Replacement Contractor in Calabasas
As a roof replacement contractor working in Calabasas, our job is to manage the three approvals every project needs: LA County permits, the insurance carrier’s fire-resistance inspection, and the HOA’s design review. The tile profile your insurer accepts can still get rejected by your HOA board if the color drifts off palette. We’ve handled that sequence enough times to know the order it has to happen in. A full roof replacement in Calabasas starts around $18,000 for a modest single-story with a simple hip, and climbs past $40,000 for a two-story Mediterranean with clay tile, multiple valleys, and decking replacement. You’ll have a written, line-item price before anything starts.
Asphalt and Architectural Shingles
Some Calabasas homes on the eastern edge near Canoga Park and Woodland Hills were built with asphalt shingles, especially the 1980s track homes south of the 101. We install GAF and CertainTeed architectural shingles rated for Class A fire when paired with the right underlayment. A shingle replacement on a Calabasas home typically lands between $18,000 and $30,000, and it’s the fastest path to a compliant roof when your HOA allows it. Not every HOA here does.
Flat Roofing
Flat roof sections show up on Calabasas homes with modern additions, garage wings, or cantilevered living spaces. We install flat roofing systems from GAF and Boral with tapered insulation where drainage needs help, and we flash every parapet wall to the same fire-resistant standard as the pitched sections. Flat roofing on a Calabasas addition runs $15 to $25 per square foot. If the flat section ties into a tile main roof, we treat the transition as a fire detail, not an afterthought.
Trusted Brands We Service in Calabasas
Birchbark Roofing works with materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Calabasas homes, that matters because your HOA will likely spec a particular tile profile and color, and your insurance wants a documented Class A assembly. We don’t push one brand. We spec the material that fits the roofline, the wind exposure on your side of the canyon, and the approval you already have in hand. Parts and materials come from our regional supply network serving Calabasas, so we’re not waiting on a truck from out of state.
Common Roof Replacement Problems We See in Calabasas Homes
- Combustible decking under old tile: Post-Woolsey, the most common driver of full replacement in Calabasas is OSB decking with no fire-resistant underlayment beneath concrete or clay tile. It looks fine from the street, but your insurer won’t renew without a tear-off and a documented Class A assembly.
- Santa Ana wind damage at roof-to-wall interfaces: The canyons around Calabasas act as wind tunnels, with gusts over 50 mph lifting poorly fastened tiles and driving embers into valleys and sidewall flashings. Mechanical fastening counts and ice and water shield in the valleys aren’t upgrades here. They’re baseline.
- HOA material conflicts: In gated communities like The Oaks at Calabasas, the tile profile and color palette are approved by a design board. A replacement spec that clears the county and your insurer can still stall until the HOA signs off, which adds a week or more if not managed early.
- Aging 1980s track homes south of the 101: These shingle roofs predate current fastening schedules and often show lifted shingles, failed pipe collars, and rotted edge boards. A repair quote often turns into a replacement once we open the decking and show you what’s under it.
Pricing for Roof Replacement in Calabasas, CA
Here’s the honest range: a straightforward shingle replacement in Calabasas runs $18,000 to $28,000. A concrete or clay tile replacement on a two-story hillside home with decking replacement runs $28,000 to $45,000. What moves the number is decking condition, roof pitch, the tile profile your HOA approves, and whether we’re replacing one layer or two. You’ll see every line item in writing before we start, and the price won’t change unless you approve a change order in writing. Call (424) 766-4937 for a free estimate. We’ll walk the roof, open the decking where needed, and give you a real number, not a range brochure.

FAQs About Roof Replacement in Calabasas
Yes. Calabasas sits entirely within a Very High Fire Hazard Severity Zone, so California code requires a Class A fire-rated assembly on any roof replacement. That means the underlayment, the decking, and the surface material all have to work together as a fire-rated system, not just the top layer. We document the full assembly for the county inspector and for your insurance carrier. Call (424) 766-4937 and we’ll explain what your specific roof needs to pass.
Because after the Woolsey Fire, carriers inspected homes and found concrete tile roofs sitting on combustible OSB decking with no fire-resistant underlayment under them. In a wind-driven ember storm, that assembly burns from underneath even though the tile on top never ignites. Carriers now condition policy renewal on a documented Class A assembly, which usually means a full tear-off. We photograph the old decking, install the fire-rated underlayment, and give you the documentation to send your carrier.
Yes. In gated communities like The Oaks at Calabasas, the HOA design review board controls material profiles and color palettes, and their approval is separate from the county permit. A tile profile that clears LA County and your insurer can still get rejected by the board. We manage that review early, because the wrong tile arrives and the project stalls. Call (424) 766-4937 and we’ll help you gather the HOA submission before the permit goes in.
They drive the fastening schedule and the valley details. Winds funneling through the canyons off Mulholland Highway regularly hit 50 to 60 mph, and they lift tiles that are adequately fastened for flatland LA. We mechanically fasten tile to the engineer’s specified count, run ice and water shield through every valley, and treat roof-to-wall intersections as fire details. That’s the difference between a roof that survives a Santa Ana event and one that loses tile on the first gust. Call (424) 766-4937 for a quoted fastening spec on your home.
It needs to show the decking scope, the underlayment type, the tile or shingle profile with manufacturer and color, the fastening method, the valley treatment, the ridge detail, and the warranty. Plus permits, HOA coordination, debris haul, and clean-up. Most quotes in Calabasas leave out the decking replacement and then “find it” after tear-off. Ours won’t. You’ll know the decking condition before you sign because we’ll inspect it first, and every surprise gets priced and approved in writing before we touch it. Call (424) 766-4937 for a free estimate that actually compares to your other bids.
