Fast, Reliable Roof Installation Across Calabasas
A full roof installation in Calabasas typically runs between $18,000 and $45,000 for most single-family homes, with larger estates in communities like The Oaks or Mountain View Estates reaching $60,000 or more. That range covers tear-off, decking repairs, underlayment, and materials, with tile and high-end architectural shingles at the upper end. Calabasas is not a market where you guess. The city sits inside a Wildland-Urban Interface zone, which means fire code drives material choices, and many gated HOAs add another layer of approval before the first nail goes in. Mercer Roofing handles both, and we put every price in writing before any work starts. Call (341) 217-2677 to schedule your free estimate.

Why Mercer Roofing Co Woodland Hills Is Calabasas’s Preferred Roof Installation Company
Homeowners in Calabasas call us because we treat the front door the same way we treat the roofline. Before any technician arrives, you receive their name and photo. When they knock, they present a photo ID badge. Uniformed. Background-checked. That is the Threshold Verified standard, and Grant Whitlock holds every Mercer job to it. For a homeowner alone during the day, or a parent with young kids, that changes how a roofing visit feels.
Our work in Calabasas covers everything from simple re-roofs off Las Virgenes Road to full tear-offs on hillside lots above Mulholland Highway. We know which HOAs require specific tile profiles, which neighborhoods need extra staging care on narrow streets, and how Santa Ana season shifts our scheduling and job-site protocols. We coordinate with the city when permits are required and with your HOA when architectural review applies. One call to (341) 217-2677 starts that process.
Every project ends the same way: a written guarantee covering the work for 365 days. If it is not right, we make it right. That is our 365-Day Done Right Promise, and it is included with every installation, not sold as an add-on. Dispatch and scheduling are coordinated from our Los Angeles office; the crews themselves serve Calabasas locally.
Styles & brands we work with
Roof Flashing Installation in Calabasas
Roof flashing installation in Calabasas protects the places where your roof meets a wall, chimney, skylight, or valley. Flashing is the metal, usually galvanized steel or aluminum, that directs water away from those joints. When flashing fails, water gets under the roofing material and into the decking, often without showing itself until the damage is done. Calabasas homes built in the 1980s and 1990s often have original flashing that is nearing the end of its service life, and the dry-heat expansion cycles we get here can loosen old seals faster than coastal climates do.
What a flashing replacement involves
We remove the old flashing, inspect the surrounding decking for rot, and install new metal with proper overlap and sealant. On a typical Calabasas home, flashing replacement around a chimney or skylight runs $600 to $1,800 depending on access and how much surrounding shingle or tile must be lifted. Full re-flashing during a roof installation adds roughly $1,200 to $3,500 to the project total, based on roof complexity.
When Calabasas homeowners usually call
Most flashing calls come after a winter rain shows a ceiling stain near a chimney or on a wall under a roof valley. Santa Ana winds can also curl or lift flashing at the roof edge, especially on older homes along canyon-rim lots in the Bird Streets or near Calabasas Lake. If you see daylight at a roof joint or granules collecting in a gutter below a valley, it is worth a closer look before the next rainy season.
TPO Roofing Installation in Calabasas
TPO roofing installation in Calabasas is a natural fit for flat or low-slope sections, common on the modern and Mediterranean-influenced homes along streets like Park Granada and in some larger estates with flat parapet sections. TPO, or thermoplastic polyolefin, is a single-ply membrane that reflects heat rather than absorbing it. On a Calabasas afternoon in August, a white TPO surface can run substantially cooler than a dark modified-bitumen roof, which helps with upstairs cooling loads and extends the life of the membrane.
What TPO installation costs here
For a typical flat-roof section on a Calabasas home, TPO installation runs $9 to $14 per square foot installed. That includes removal of the old membrane, any necessary insulation or cover board, and full TPO installation with heat-welded seams. Most flat sections on single-family homes fall in the $8,000 to $20,000 range depending on size, access, and whether the deck needs repairs before the new membrane goes down.
Why seams matter on Calabasas flat roofs
TPO seams are heat-welded, not glued. Done right, a welded seam is stronger than the membrane itself. Done wrong, it leaks. The heat and UV cycles in this part of the Santa Monica Mountains punish cheap installation quickly, which is why we install TPO with proper seam probing and testing before we call the job done. If you have a flat section that ponds water after rain, mention it on the estimate call; drainage corrections can be built into the quote.
Trusted Brands We Service in Calabasas
We install and service roofing systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Calabasas homeowners in WUI zones, we lean on Atlas and IKO for their strong Class A fire-rated architectural shingle lines, and Boral for tile profiles that match what local HOAs expect on Spanish and Mediterranean homes. Because we work with these brands consistently on Calabasas projects, we can often get materials staged faster than a contractor running one-off orders. Your estimate will specify the exact material, profile, and color before you sign anything.

AfterCommon Roof Installation Problems We See in Calabasas Homes
- Non-Class A materials from out-of-area contractors. We have seen roofs installed with materials that do not meet Calabasas WUI fire code. The homeowner pays twice: once for the wrong roof, again for the correction. We specify Class A from the first bid.
- HOA stop-work orders. Starting without architectural approval in The Oaks or Mountain View Estates can shut a job down mid-tear-off. We confirm HOA requirements in writing before we schedule the crew.
- Failed flashing at chimneys and valleys. The combination of intense summer heat and winter rain cycles stresses old flashing. Homes from the 1980s and 1990s are at the age where this shows up as slow leaks.
- Debris piles during Santa Ana season. Open-flame roofing and loose debris on a windy day in Calabasas is a fire hazard and a fast way to get a call from the fire marshal. We run clean job sites, spray down work areas as needed, and never leave piles overnight.
Pricing for Roof Installation in Calabasas, CA
For a complete tear-off and re-roof on a typical Calabasas single-family home, expect $18,000 to $45,000. Architectural shingle systems sit at the lower end. Concrete or clay tile systems, especially the profiles HOAs in The Oaks and Mountain View Estates often mandate, sit higher. Larger estates with complex hips, valleys, and multiple roof planes can exceed $60,000. Flat-roof TPO sections add based on square footage, generally $9 to $14 per square foot. Every estimate includes a written line-item price before any work starts, and the price does not change unless the scope does, in writing. Call (341) 217-2677 for your free estimate.

FAQs About Roof Installation in Calabasas
In most gated communities, yes. Neighborhoods like The Oaks and Mountain View Estates have architectural review committees that must approve material type, color, and profile before work starts. Skipping this step can trigger a stop-work order and force a re-installation at your expense. We handle HOA submission for you as part of the pre-construction process, and we do not schedule a single day of labor until the approval is in writing. Call (341) 217-2677 and we will walk you through what your HOA requires.
Calabasas sits in a designated Wildland-Urban Interface zone, which means the city enforces Class A fire-rated roofing materials and ember-resistant vents. Class A is the highest rating, meaning the material resists severe fire exposure. This applies to shingles, tile, and the underlayment assembly below them. Many neighboring Los Angeles suburbs do not enforce this, so an out-of-area contractor might quote you a cheaper roof that does not pass Calabasas code. We specify Class A on every Calabasas bid. For an exact quote on your roof, call (341) 217-2677.
We stage materials in sections and coordinate delivery so we never block a shared driveway or narrow canyon road longer than necessary. On hillside lots with limited flat ground, we may split deliveries across multiple days and use smaller staging areas near the roofline. For gated communities, we confirm guest parking and access rules with the HOA ahead of time. The goal is to keep the site clean, the road clear, and your neighbors uninterrupted. When we quote your job, we account for access, because a tight lot genuinely changes how we schedule the work. Call (341) 217-2677 for a free estimate that includes site access planning.
Yes. We install to manufacturer wind specifications that account for the high-gust conditions Calabasas sees during Santa Ana season. That means proper nailing patterns, starter strips, and edge detailing that keeps shingles and tile from lifting when winds push 50 to 70 mph through the canyons. We also schedule tear-offs with wind in mind, avoiding open-flame work and keeping every scrap secured. If a roof fails under normal conditions within 365 days, our Done Right Promise covers the fix. For specifics on your roof’s wind rating, call (341) 217-2677.
Calabasas enforces construction noise limits, and most gated communities have additional rules about start times, Sunday work, and contractor hours. We confirm the specific restrictions for your neighborhood before the crew arrives and schedule the loudest phases, like tear-off and decking, within permitted hours only. The crew briefs on site rules every morning. If your HOA has a quiet-hours policy or a preferred work window, we put it in the job plan. Call (341) 217-2677 and we will note your community’s rules in the quote before you commit to anything.
