Fast, Reliable Roof Repair Across Malibu
Roof repair in Malibu usually runs $450 – $2,800 depending on what failed and what the salt air has done to the fasteners holding it together. Call (805) 309-3314 and Grant or a member of our team will get a technician to your street, whether you’re up in Ramirez Canyon or down on Broad Beach Road. We’ve worked on enough Malibu roofs to know that the problem is rarely just the shingle. It’s what the coastal air has been quietly doing underneath it for years.
Why Mercer Roofing Co Thousand Oaks Is Malibu’s Preferred Roof Repair Company
The difference with us starts before a technician ever climbs a ladder. When you book with Mercer Roofing, you get the technician’s name and photo sent to your phone ahead of the visit. The same person who knocks is the person in the photo, and they’ll present a photo ID badge at your door. That’s the Threshold Verified standard we’re held to on every job, and it’s written into how we operate.
Grant Whitlock leads our Malibu roofing work, and he’s built this team around a simple promise: one written price before any work starts, and one written guarantee on every repair. That guarantee runs 365 days, and if a repair fails within that year, the second visit is free. No re-quoting, no “well, that’s a different problem now.” It’s the same problem, and it’s ours to fix.
Malibu homeowners call us from Point Dume, from the beach bungalows along Latigo Shore Drive, and from the newer builds up in Serra Retreat. The response is consistent: a live person answers the phone 24/7, we schedule around your day, and the crew shows up in clean, marked uniforms. You won’t get a subcontractor in an unmarked truck. Every Mercer technician is background-checked and identity-verified, which matters when you’re letting someone onto your roof and into your home.
Styles & brands we work with
Storm Damage Roof Repair in Malibu
Storm Damage Roof Repair in Malibu typically runs $600 – $3,400, with Santa Ana wind lifting being the most common cause. Those seasonal winds coming through the canyons peel cap sheets at the drip edge and tear loose flashing along parapets, and a roof that held fine for ten years can be compromised in a single afternoon. Leaks usually show up days later, once the next rain finds the gap.
Wind-Lifted Cap Sheets on Low-Slope Roofs
Malibu has a lot of flat and low-slope roofs, especially on the mid-century beach bungalows and the modern cliffside builds. Modified bitumen cap sheets get hot in the sun, soften, and then the Santa Anas get under any dried-out lap seam. We see it most often at the eaves and the corners. The fix involves cutting back the lifted section, re-adhering with a torch or cold-process adhesive, and sealing the laps so the wind can’t find a new edge to grab.
Debris Impact and Emergency Tarping
Palm fronds, eucalyptus branches, and anything loose on a Malibu hillside can come down hard in a storm. We respond to impact damage, check the decking below the broken tile or shingle, and tarp if the weather’s still coming. The tarp is temporary; the written estimate we give you before we start the real repair is not.
Metal Roof Repair in Malibu
Metal Roof Repair in Malibu usually costs $500 – $2,900, and the price depends heavily on whether the original installer used coastal-grade fasteners. Most metal roofs here are standing-seam or exposed-fastener panels, and exposed fasteners are exactly what they sound like: screws with rubber washers holding the panels down. Salt air eats the washer, then rust moves into the screw, then the panel starts to lift.
Replacing Corroded Fasteners on Exposed-Fastener Panels
The honest repair is replacing every failing screw in the affected section with stainless or hot-dipped fasteners, no exceptions. We’ve too often opened a 20-year-old Malibu metal roof and found the entire screw line rusted through because someone used interior screws and called it done. Those roofs leak at the laps and the ridge, and the only real fix is pulling the bad hardware and starting over with marine-grade material.
Seam and Penetration Leaks on Coastal Metal
Metal expands and contracts with the sun, and in Malibu the sun comes hard year-round. That repeated movement eventually breaks the sealant at laps, transitions, and pipe penetrations. We clean the seam, re-seal with a marine-rated product, and replace any flashing that’s lost its coating. When we leave, the fix is on paper: what we did, what it cost, and the 365-day guarantee.
Trusted Brands We Service in Malibu
We regularly work with CertainTeed, Owens Corning, and IKO shingles, and we align every Malibu repair or replacement with the manufacturer’s installation specs for coastal exposure. That matters because a warranty is only as valid as the install, and if the nails rust out, the shingle brand won’t save you. We keep a stock of stainless and hot-dipped fasteners, marine-grade flashing, and replacement boots for Malibu jobs, so we’re not running back and forth or postponing while parts ship.

AfterCommon Roof Repair Problems We See in Malibu Homes
- Rusted flashing at valleys and chimneys. Standard electroplated flashing lasts five to seven years in Malibu’s salt spray before it rusts through. We replace it with hot-dipped galvanized or stainless steel, which is what the coastal code requires.
- Leaks around skylights and vent boots. The rubber boot around a plumbing vent or skylight dries out under constant UV, then cracks, and salt air accelerates the failure. A $125 – $400 boot replacement fixes most of these before they rot the decking.
- Wind uplift on low-slope roofs. Santa Ana winds get under cap sheet laps and peel them back at the eaves. We re-adhere the lifted section and seal every lap, which is a $600 – $1,800 repair depending on how far the wind got.
- Ember intrusion on older shake and tile roofs. Malibu’s wildfire code has pushed many owners to retrofit, but gaps at the ridge vent, soffit, and fascia still let embers reach the underlayment. A repair that ignores those gaps isn’t a repair, it’s a head start for the next fire season.
Pricing for Roof Repair in Malibu, CA
Here’s what to expect, in real dollars. Shingle replacement in Malibu runs $450 – $1,800 for a standard section. Leak repair starts around $350 – $900 for a single penetration, and $900 – $2,500 if we’re opening decking to find the actual water path. Flashing repair runs $500 – $1,600. Flat roof patches run $650 – $2,200. Vent boot replacement is $125 – $400.
What moves the price up in Malibu specifically: the coastal fastener requirement. You cannot pass a Malibu roof inspection in good conscience with electroplated nails, and stainless ring-shank nails plus hot-dipped drip edge cost more than the inland hardware. It’s $100 – $400 more per repair, but the alternative rots through before the decade’s out. Call (805) 309-3314 for a written line-item estimate. It’s free, and no work starts until you’ve approved it in writing.

FAQs About Roof Repair in Malibu
Because Malibu’s coastal code requires stainless steel or hot-dipped galvanized fasteners for roof flashing, drip edge, and penetrations, and standard electroplated nails rust through within five to seven years in salt air. Inland, the same nail would last two decades. You will not see that line item on a Calabasas or Agoura Hills quote, and you should. If a Malibu roofer quotes cheap nails, they’re quoting a repair destined to fail. Call (805) 309-3314 if you want a quote with the fasteners written down, not assumed.
Yes, in most cases we can patch the failed section of built-up roofing or modified bitumen for $650 – $2,200, provided the underlying decking is still sound. We cut back the blistered or cracked area, repair or replace the deck if needed, apply new membrane and a sealed lap, and guarantee the repair for 365 days. If the roof is past fifteen years and the edges are curling everywhere, patching one spot may be throwing good money after bad. We’ll tell you straight, in writing, before anything gets started.
Yes, if you’re in a designated Wildland-Urban Interface zone, any roofing material we add must meet Class A fire rating requirements, and we’ll spec it correctly. In practical terms, that means fire-resistant underlayment, sealed gaps at the soffit and ridge, and sometimes composite or metal replacement pieces instead of whatever match might otherwise go in. The cost difference is usually $200 – $800 on a repair, and it’s not optional. We’ll tell you what your specific area requires and put it in the estimate.
Almost always, it’s the rubber boot or gasket drying out and cracking under intense coastal UV, then salt air corrosion finishing the job. The metal flashing around a skylight will also rust through faster than inland equivalents if it’s not stainless or hot-dipped. We replace boots for $125 – $400, and skylight re-flashing typically runs $500 – $1,200. The sooner it’s caught, the less decking gets replaced. Call (805) 309-3314 and we’ll inspect before the next rain.
A square is 100 square feet of roofing, and a repair quote should only include squares if the damage spans more than one small section; otherwise it’s per-piece pricing. In Malibu, accurate square counts matter because salt-exposed roofs often hide rot at the eaves, which means you may need decking replacement that a sloppy quote won’t include. Ask any roofer to show their square count and their decking assumption. We include both on every written estimate.
