AfterFast, Reliable Roof Installation Across Malibu
A new roof in Malibu costs between $18,000 and $55,000 for most homes, with high-end coastal properties on Point Dume or in Malibu Colony often running $60,000 to $120,000 when the job includes fire-rated assemblies, steep-slope rigging, and salt-air corrosion upgrades. We schedule roof installations across Malibu within 5 to 10 business days of your signed estimate, and a live person answers when you call us at (743) 200-8347. You are not calling a call center. You are calling a roofing company that knows Latigo Canyon, knows PCH, and knows that a Malibu roof has to do two jobs at once: resist firebrands and survive salt air.
Local expertise matters here more than in almost any other California coastal city. The marine layer that keeps Malibu cool also eats exposed metal. The Santa Ana winds that clear the sky in October also carry embers for miles. A roofer who only knows one of those problems will install a roof that fails the other way. We build for both.
Why Mercer Roofing Is Malibu’s Preferred Roof Installation Company
Homeowners in Malibu choose Mercer Roofing because we put the price, the plan, and the person in writing before any work starts. Every technician is background-checked, identity-verified, and arrives in a clean uniform with a photo ID badge at the door. We send you the technician’s name and photo before they arrive, so you know exactly who is coming up your driveway on Rambla Pacifico or down your street in Point Dume.
We are part of the Threshold Group family, founded in 2000, and every Mercer location is independently owned and operated under the Threshold Verified standard. That means the background check and the badge are not optional. They are the floor.
Grant Whitlock leads our team, and he holds every project to the same written standard: price before work starts, written guarantee on every repair, and a 365-Day Done Right Promise. If the installation is not right within a year, we make it right. Malibu homeowners tell us the same thing after the job is done: the certainty was worth as much as the craftsmanship.
TPO Roofing Installation in Malibu
TPO Roofing Installation in Malibu runs $14,000 to $32,000 on a typical flat or low-slope roof, and it is the roof system we most often recommend for post-Woolsey rebuilds that use contemporary flat and low-slope designs. TPO is a single-ply thermoplastic membrane that gets heat-welded at the seams, which creates a monolithic surface that sheds water well and reflects heat instead of absorbing it. For Malibu homes with modern architecture, solar panel mounts, or rooftop decks, TPO is often the right material.
Why TPO Makes Sense on Post-Fire Rebuilds
Many Malibu homes rebuilt after 2018 use flat or low-slope roof planes because the architectural style shifted toward modern forms. TPO handles those low slopes better than shingles, which start to leak when the pitch drops below 2:12. We install TPO with Class A-rated cover boards where the permit requires it, and we detail the parapets and penetrations with corrosion-resistant metal.
What TPO Installation Involves in Malibu
We remove the old roofing down to the deck, inspect the framing for fire damage or undersizing, replace any failed decking, then mechanically fasten or fully adhere the TPO membrane. The seams are heat-welded on site. Flashing at the parapets gets done with stainless or coated aluminum that will not pit out from salt air in five years.
Shingle Roof in Malibu
Shingle Roof installation in Malibu costs $11,000 to $28,000 for a typical 1,800 to 2,600 square foot home, and it remains the most practical choice for the canyon ranch homes and mid-century cottages that line PCH and the roads off Malibu Canyon. We install GAF architectural shingles most often here, with CertainTeed and Owens Corning also common choices. The shingle itself matters less than the assembly underneath it, which has to meet Malibu’s fire-hardening code requirements.
Class A Assemblies and Ember-Resistant Detailing
Malibu sits in a Very High Fire Hazard Severity Zone, which means every new shingle roof must meet California Chapter 7A requirements. That includes a Class A fire-rated assembly and ember-resistant vents at the ridge and eaves. A roofer who bids a standard LA County shingle job without checking the permit conditions will fail inspection after the roof is already on. We check the conditions before we bid.
Shingle Tear-Offs on Older Malibu Homes
When we tear off an older shingle roof on a Malibu home, we frequently find the decking is brittle from decades of marine moisture, or the framing is undersized for the current span tables. We write an allowance into the contract for exactly this. If we open the deck and find framing that needs sistering or replacement, we stop, price it, and get your written approval before we drive another nail.
Trusted Brands We Service in Malibu
We install and service GAF, CertainTeed, Owens Corning, and Atlas roofing systems, and we stock common flashings, ridge vents, and fasteners in our Los Angeles warehouse so Malibu jobs do not stall waiting on parts. GAF is the brand we reach for most often on Malibu homes because their architectural shingle line pairs well with the Class A assemblies and ember-resistant detailing the city’s rebuild permits demand. We also recommend Boral concrete tile for homeowners who want the look of old Malibu wood shake without violating the VHFHZ code, and Tamko for steep-slope canyon homes that need a rugged shingle with good wind uplift ratings. The brand matters, but the flashing, underlayment, and fasteners matter more. We specify all of them for coastal corrosion.
Common Roof Installation Problems We See in Malibu Homes
- Salt-eaten flashings and fasteners. Marine air off the Pacific pits standard aluminum flashing and galvanized nails within a few years. A roof that looks solid from the street can have failing metal at every pipe boot, valley, and chimney.
- Undersized or fire-damaged framing. Older Malibu homes often have framing that does not meet current span loads, and some post-Woolsey repair work was done quickly. Once the decking is off, the crew has to stop and price the framing correction before the install continues.
- Missing or failed underlayment in valleys. Coastal storms drive rain sideways into Malibu’s canyon homes, and valleys are where leaks start. Many older roofs here have one layer of felt and no ice-and-water shield in the valley.
- Non-compliant roof assemblies on rebuilds. Post-Woolsey permit conditions require Class A assemblies and ember-resistant vents. A roofer who skips this detail gets the roof torn off and done again. We check the permit packet before we bid.

FAQs About Roof Installation in Malibu
Older Malibu homes were often built before modern span tables, and decades of marine moisture weakens the decking and the framing below it. Once the decking is off, we frequently find rafters that are undersized for the current code, fire-damaged, or both. We also find old electrical runs stapled to the underside of the sheathing, which the city requires to be relocated when the roof plane is opened. We write an allowance into the contract, and any framing or wiring work gets priced and approved in writing before we proceed. Call (743) 200-8347 if you want a tear-off estimate that accounts for this reality up front.
No. Malibu is a Very High Fire Hazard Severity Zone, and wood shake and wood shingle roofs are effectively prohibited on new construction and post-fire rebuilds under the current code. Homeowners who want the rustic look can choose Class A-rated composite shingles or concrete tile that mimic wood shake, and we install both. The composite options from brands like Boral look close enough that most neighbors cannot tell the difference from the street. We can show you samples before you commit.
We install TPO on most low-slope and flat Malibu roofs, with a Class A-rated cover board where the permit requires one and corrosion-resistant metal at every parapet and penetration. The TPO membrane gets heat-welded at the seams, so there are no exposed fasteners to rust. We also detail the roof-to-wall transitions carefully, because that is where wind-driven rain from a coastal storm finds its way in. Call (743) 200-8347 and we will walk you through the options.
Salt air corrodes standard aluminum flashing, drip edge, and galvanized fasteners, which means a roof that looks fine from the curb can have failing metal at every pipe boot and valley within three to five years. We specify stainless steel or coated aluminum for all exposed metal on Malibu jobs, and we use fasteners rated for coastal exposure. The upgrade is a small fraction of the total job cost and it doubles or triples the life of the flashing.
Compare what each bid says about Class A fire rating, ember-resistant vents, and corrosion-resistant metal. If one bid does not mention Chapter 7A or salt-air detailing, it is not a Malibu bid, it is a generic LA County bid. Then compare whether the contractor writes an allowance for hidden framing work. The lower bid often has no allowance, which means the price moves the day the decking comes off. We put the allowance in writing before you sign, and every change gets priced and approved before we do the work. Call (743) 200-8347 for a free estimate with those numbers in writing.
