Fast, Reliable Roofing Company Across Calabasas
Finding a roofing company in Calabasas that actually understands what your roof has to survive is harder than it should be. Between the Very High Fire Hazard Severity Zone requirements, guard-gated HOA rules in communities like The Oaks and Mountain View Estates, and the Santa Ana winds that tear at ridge caps every fall, Calabasas roofs face a set of demands most roofers never deal with. Mercer Roofing handles all of it: WUI-compliant materials, HOA pre-approvals, and written pricing locked before anything gets ordered. Call (341) 217-2677 for a free estimate and you’ll talk to a live person, day or night.
Why Mercer Roofing Co Woodland Hills Is Calabasas’s Preferred Roofing Company
We didn’t stumble into Calabasas work. We’ve walked roofs off Parkway Calabasas, Mulholland Highway, and Las Virgenes Road, and we know what the inspectors at Los Angeles County Fire look for in a Wildland-Urban Interface zone. That local knowledge changes how we quote, how we order, and how we build. When a homeowner in Hidden Hills-adjacent Calabasas needed a re-roof to pass a fire clearance before escrow, our crew knew exactly which ember-resistant vents the WUI checklist required and had them on the truck, not on backorder.
Calabasas homeowners tell us the same thing: the stranger-at-the-door risk is real. So we removed it. You’ll get the name and photo of your technician before they arrive. They’ll be in a clean, marked uniform and they’ll badge in with a photo ID at your door. That’s the Threshold Verified standard, and every tech who works under the Mercer name meets it. No exceptions, no surprises, no nameless guy with a ladder showing up at 7 a.m.
Grant Whitlock runs our operation, and he’s the one who insisted on the 365-Day Done Right Promise: if the work isn’t right within a year, we make it right, backed by a written guarantee on every repair. That’s not marketing language. That’s a contract line.

Metal Roof Installation in Calabasas
Metal roof installation in Calabasas is a serious investment that pays off in fire resistance, and it’s one of the smartest calls you can make in a designated Very High Fire Hazard Severity Zone. A standing seam metal roof on a typical Calabasas hillside home runs $28,000 to $55,000 depending on square footage, pitch, and whether we’re tearing off the existing roof. The price we write down before work starts is the price you pay. No change orders when the underlayment quote comes back higher than the salesman guessed.
Metal roofs carry a Class A fire rating, which is non-negotiable for WUI clearance in Calabasas. They also stand up to Santa Ana wind uplift far better than most tile profiles, especially when we install the concealed clip system rather than exposed fasteners. For homes on exposed ridges above Mulholland Highway or along the canyon edges, that wind rating matters every single year.
Standing Seam for Hillside Homes
We spec 24-gauge standing seam panels with a PVDF coating for most Calabasas metal installations. The coating holds up to sun exposure that would chalk a lesser finish within five years. It’s a clean, flat profile that works with the modern architecture you see in the newer Calabasas subdivisions, not just the Mediterranean estates.
Metal Re-Roofs Over Tile
Taking a 1990s tile roof down to decking and replacing it with metal is a bigger job than a layover, and it’s the right move when the decking is compromised or the HOA says no to mixed profiles. We handle the full sequence: tear-off, decking repair, peel-and-stick underlayment, and panel installation, all coordinated so your home never sits exposed before a rain event.
Residential Roofing in Calabasas
Residential roofing in Calabasas almost always means tile. The city’s housing stock from the 1980s onward leans heavily toward Spanish and Mediterranean styles, and those barrel or flat tile profiles are part of what the HOAs in communities like The Oaks protect. A full tile re-roof on a 3,000-square-foot Calabasas home typically runs $35,000 to $65,000, with the wide range driven by tile profile, decking condition, and whether the home is on a steep hillside lot that requires staging and safety rigging.
We work with homeowners who want the job done once. That means ordering the exact tile color and profile the HOA approved, not the closest thing a supplier had in stock. It means replacing rotted decking at the eaves instead of nailing new tile into spongy wood. And it means laying a full ice and water shield, not just felt, before the tile goes down. Calabasas gets real winter rain storms, and the valleys on Mediterranean-style homes are where leaks always start.
Full Tile Re-Roofs
When we strip a Calabasas tile roof, we photograph the decking before anything gets covered. You see what we see. If the plywood is shot, you’ll see the rot in the photo and approve the replacement cost in writing before a single new sheet goes down. That transparency is why Calabasas homeowners keep calling us back for their second roof.
Roof Repairs and Flashings
Repairs in Calabasas range from a few hundred dollars for a cracked tile or resealed pipe boot to $3,000 to $7,000 for valley flashing replacement or skylight re-flashing. Every repair gets a written guarantee. If it fails within 365 days, we come back free.
Trusted Brands We Service in Calabasas
We install and repair roofs using manufacturer-recognized shingle and tile brands, and on Calabasas jobs that most often means Owens Corning, IKO, and Boral tile. We keep common replacement profiles and colors in our local staging so a Calabasas homeowner isn’t waiting three weeks for a matching Boral flat tile after a branch goes through the roof. Whether you need a full replacement or a repair on an existing Owens Corning system, we know how these materials perform in this climate and we service them properly.
On a custom Mediterranean off Parkway Calabasas in Mountain View Estates, our crew stripped a cracked 1990s Boral tile roof after the HOA approved a matching ‘Tuscan Sunset’ profile. We replaced rotted decking at the eaves, laid a full ice and water shield over the whole roof, and installed new Class A ridge vent and powder-coated drip edge before the tile went down, all against a written, fixed price that locked in the tile and underlayment before Santa Ana season delayed material deliveries.

AfterCommon Roofing Problems We See in Calabasas Homes
- Cracked tile from heat and age: The Calabasas sun bakes tile for decades until it delaminates or cracks along the nail lines. Once water gets under cracked tile, the felt and decking fail within one or two rainy seasons.
- Valley flashing failures on Mediterranean designs: Homes with multiple roof planes and deep valleys collect debris and water. When valley flashing was poorly soldered or installed with the wrong profile, leaks show up on the ceilings below.
- HOA compliance surprises: Homeowners discover mid-project that their board requires a specific tile color, and the roofing company they hired didn’t check the CC&Rs. The job stalls, the tile gets rejected, and the homeowner eats the restocking fee. We verify HOA requirements before we order.
- Santa Ana wind damage at ridges and rakes: Wind uplift peels ridge caps and lifts tile edges, especially on elevated lots. If the original install didn’t include proper wind mitigation clips, the roof sheds pieces every strong Santa Ana event.
Pricing for Roofing Company in Calabasas, CA
Roof repairs in Calabasas typically run $450 to $2,800 for common fixes like resealing flashings, replacing cracked tile, or repairing soffit and fascia.

These are honest ranges for Calabasas’s market. The factors that move the number: roof square footage, pitch, number of valleys and skylights, decking condition, and whether your HOA requires a specific tile profile with a long lead time. We write the price before work starts, including materials and labor, so there’s no jump between the quote and the signed contract. Call (341) 217-2677 for a free written estimate.

FAQs About Roofing Company in Calabasas
Yes, HOAs in guard-gated Calabasas communities like The Oaks have architectural review boards that reject tile colors and profiles that don’t match the approved palette, and some require board sign-off before any work begins. We pull the HOA requirements before we order, submit the color and profile for approval, and get written confirmation before the first bundle ships. Call (341) 217-2677 and we’ll walk you through exactly what your board needs.
Calabasas sits inside a designated Very High Fire Hazard Severity Zone, so WUI code requires Class A fire-rated roofing material, ember-resistant vents, and specific valley and flashing details that prevent burning debris from lodging under the roof edge. A standard roof in the flatlands of LA wouldn’t need those ember-resistant vents or the same non-combustible underlayment. We build every Calabasas roof to pass fire clearance inspection. Call (341) 217-2677 for an evaluation of whether your current roof would pass.
That jump happens when a roofing company quotes without measuring, then writes the contract after the real material order comes back or after the supplier raises tile prices. We measure during the estimate, confirm the tile profile and underlayment spec, and write a fixed price that includes everything. The number on your estimate is the number on your contract. Call (341) 217-2677 and you’ll see what a locked price looks like.
We match the exact profile, not a close-enough patch. Boral and other tile manufacturers still produce most profiles installed in 1980s and 1990s Calabasas homes, and we source the specific color blend your roof has aged into. If the profile is discontinued, we’ll tell you before ordering and work with your HOA on an approved alternative. Call (341) 217-2677 and we’ll identify your current tile profile during the estimate.
We treat every valley and skylight as a potential leak path and build accordingly: full ice and water shield in the valleys, soldered metal valley flashing where the roof design allows, and reglet-flashed skylights with the correct cricket detail so water never pools against the glass. Calabasas’s Mediterranean homes have complex roof geometry, and that’s exactly where we focus our attention. Call (341) 217-2677 to schedule a post-storm inspection before the next heavy rain.
