AfterFast, Reliable Roofing Company Across Malibu
If you’re searching for a Roofing Company that actually understands what a Malibu roof goes through, you’re in the right place. Malibu isn’t like inland LA. Salt air eats standard flashing within a few years. Santa Ana winds push firebrands onto roof decks. And the VHFHZ fire code here is the strictest in the county. We work on all of it. Every job starts with a written price before any work begins, and every repair carries a written 365-day guarantee. Call (743) 200-8347 and a real person answers, day or night.
Why Mercer Roofing Is Malibu’s Preferred Roofing Company
Malibu homeowners call us because we don’t send a stranger to your door. Before any technician arrives, you get their name and photo sent to you. They pull up in a marked uniform, badge in with a photo ID, and only then does the work start. For people home alone, parents with young kids, and older homeowners, that badge-at-the-door step is the single most important thing we do. Every Mercer technician is background-checked, identity-verified, and held to the Threshold Verified standard under the Threshold Group quality framework. Founded in 2000, Mercer Roofing is part of the Threshold Group family of home-service companies, and this location is independently owned and operated.
Our reputation in Malibu is built on showing up with a written price and a written guarantee. Reviews from Malibu customers consistently mention two things: the technician’s name and photo arrived before the visit, and the invoice matched the quote. That’s not an accident. It’s how we work. Written by Grant Whitlock, who leads Mercer Roofing and sets the standard that every Malibu job is quoted in writing before a single nail is driven.
Residential Roofing in Malibu
Residential Roofing in Malibu has to solve two opposing problems at once: coastal corrosion and fire-code compliance. A roof that works in Agoura Hills won’t necessarily make it here. Salt-laden onshore air corrodes galvanized fasteners, standard aluminum flashings, and unsealed gutters within a few years, not decades. Yet the same home sits in a Very High Fire Hazard Severity Zone, legally requiring Class A fire-rated roofing assemblies and ember-resistant vents under California’s Chapter 7A. Get either one wrong and you’re redoing work or failing an inspection.
Salt-Air Roof Systems for Beach Cottages
Mid-century beach cottages along PCH and through Malibu Colony need stainless or hot-dip galvanized fasteners, marine-grade flashing, and sealed penetration boots. Standard aluminum components chalk up and pit after a few summers of salt fog. We see it constantly. A typical residential re-roof on a Malibu beach cottage runs $18,000 to $42,000 depending on decking condition and slope complexity.
Class A Assemblies for Canyon Homes
Homes in Latigo Canyon, Malibu Canyon, and the hills around Point Dume carry the VHFHZ requirements. That means Class A composite shingles or concrete tile, ember-resistant ridge vent, and ignition-resistant vents. We steer homeowners toward brands like GAF, CertainTeed, and Owens Corning for composite options that hold up to both ember showers and marine air. Canyon re-roofs typically run $24,000 to $58,000 because of the steep terrain and rigging access.
Roof Maintenance in Malibu
Roof Maintenance in Malibu isn’t optional. The marine layer keeps roofs damp in the morning, the salt air keeps working on exposed metal all day, and the Santa Anas show up every fall. We recommend a professional roof check every 18 months on coastal properties and every year on canyon homes where fire clearance matters. A standard maintenance visit in Malibu runs $295 to $595, depending on roof size and pitch.
Coastal Corrosion Checks
We walk every roof looking for the specific ways Malibu kills flashing: valley metal rusting through, penetration boots going chalky, and drip edge separating at the eaves. Catching these early is a few hundred dollars. Ignoring them means decking rot and a full re-deck years before the shingles would have failed.
Pre-Wind Season Inspections
Before the fall Santa Ana season, we check that every shingle tab, flashing corner, and vent is secure. Wind-driven embers find any gap. Our maintenance visit includes a written condition report with photos, so you have a record of what’s solid and what needs attention before fire season arrives.
Trusted Brands We Service in Malibu
We install and repair roofing systems from GAF, CertainTeed, Owens Corning, and Atlas, and we also offer our Roof Repair in Malibu for fast local turnaround. For homeowners chasing that rustic canyon look that’s now code-restricted, we spec Class A composite shingles from brands that mimic wood shake so closely you’d have to touch it to know. We keep common flashing profiles and ember-resistant vent parts stocked locally for Malibu fast turnaround. No waiting weeks for a part to ship from a warehouse when your roof is already open.
Common Roofing Problems We See in Malibu Homes
- Salt-eaten flashing and fasteners: Standard galvanized drip edge and aluminum penetration boots corrode through within five to seven years along the coast. The shingles above them still look fine, which tricks homeowners into thinking the roof is healthy. It isn’t.
- Post-Woolsey rebuild roofs spec’d wrong: We see rebuilds where someone ordered wood shake for a canyon home, not realizing the VHFHZ designation flatly prohibits it. The homeowner then fails inspection and pays for a second spec before a single hammer swings.
- Ember-vulnerable vents and gaps: Standard gable vents and ridge gaps let wind-driven firebrands into the attic. Malibu’s fire code requires ember-resistant vents on new and altered roofs. Older homes still have the vulnerable ones.
- Flat and low-slope roof failures on contemporary rebuilds: Many post-fire Malibu builds went contemporary, with flat or low-slope roof planes. Improper TPO or modified bitumen installation from inland crews causes ponding and seam splits within a few seasons. These roofs need a coastal-spec detail or they fail early.

FAQs About Roofing Company in Malibu
A Malibu roof costs more because the material spec has to be better. The coastal-spec version of the same job uses stainless and hot-dip galvanized fasteners, marine-grade flashing, and ember-resistant vents that inland jobs skip. The inland-spec version might save you $3,000 to $6,000 up front, but those standard aluminum flashings corrode through within a decade. You pay for the re-flash in year eight instead of year thirty. Call (743) 200-8347 and we’ll walk you through the line items.
No. Malibu’s Very High Fire Hazard Severity Zone designation prohibits wood shake and wood shingle on all new construction and post-fire rebuilds. This surprises even longtime local builders. If you want that rustic canyon look, we spec Class A-rated composite shingles or concrete tile that mimic the appearance. Same feel, fire-code legal, and you won’t fail inspection. Call (743) 200-8347 for a free estimate on the right spec.
Standard galvanized drip edge and aluminum penetration boots start showing serious corrosion within five to seven years on coastal properties from Malibu Colony up through Point Dume. The shingles above them last twenty to thirty years, which means the roof fails from the inside out while it still looks fine from the ground. We recommend a corrosion check every 18 months. Call (743) 200-8347 to schedule one.
Most Malibu hillside rebuilds on steep lots in Latigo Canyon and Malibu Canyon use pitched roofs with Class A composite or concrete tile. But many post-Woolsey custom homes went contemporary, with flat or low-slope sections that need TPO or modified bitumen installed with coastal-spec details like stainless termination bars and sealed seams. Both work here if spec’d correctly. Which one fits your home is a conversation, not a guess. Call (743) 200-8347.
Look at the flashing spec, the fastener spec, and whether ember-resistant vents are listed as line items. A Malibu bid should call out stainless or hot-dip galvanized fasteners, marine-grade flashing, and Class A assembly details. If the bid is just a shingle brand and a square-foot number, it’s an inland-spec job priced like a coastal one. Call (743) 200-8347 and we’ll give you a written quote that lists every component.
When you’re ready to get a written price on your Malibu roof, call (743) 200-8347. A live person answers. We’ll schedule a visit, send you the technician’s name and photo before they arrive, and put everything in writing before any work starts.
