Styles & brands we work with
Storm Damage Roof Repair in Los Angeles
Storm damage roof repair in Los Angeles is almost always driven by Santa Ana winds, which can hit 50 to 70 mph in the foothills and lift shingles that weren’t nailed to spec. We also see damage from winter rain events that expose failed flashing and clogged valleys. A typical wind-driven shingle repair in Los Angeles runs $450 to $850, while a more involved storm repair with decking replacement can reach $1,200 to $1,800 depending on the extent of the damage.
What the Job Involves
We inspect the windward side of the roof first, because that’s where Santa Ana damage concentrates. Lifted shingles get re-secured or replaced, damaged underlayment gets cut out and patched, and flashing around vents and chimneys gets re-sealed. If decking has been exposed to repeated moisture, we’ll replace that section before laying new material. Every storm repair includes a written guarantee, and if it fails within 365 days, the second visit is free.
When to Call Us
After a strong wind event, look for shingles in your yard, lifted edges you can see from the ground, or water stains on ceilings after the first rain. The sooner we address wind damage, the less water gets into the decking. Call (213) 521-8272 and we’ll schedule an inspection with a written price before any work starts.
Metal Roof Repair in Los Angeles
Metal roof repair in Los Angeles is common on apartment buildings, carports, and the occasional hillside modern home. The primary failure mode here is fastener corrosion from coastal salt air, especially within a few miles of the beach. A typical metal roof repair in Los Angeles, such as replacing corroded fasteners and re-sealing penetrations, runs $500 to $1,000. Larger panel replacement jobs can reach $1,500 to $2,500.
Fastener and Penetration Work
In neighborhoods like Venice, Mar Vista, and Playa del Rey, we regularly find fasteners that have rusted through completely, leaving panels loose and letting water through the screw holes. Our team removes the failed fasteners, replaces them with corrosion-resistant hardware, and re-seals around every penetration with a compatible sealant. Flashing around pipes and vents gets the same treatment.
Coating and Seam Repair
Older metal roofs often fail at the seams, where the original sealant has dried and cracked after years of Los Angeles sun. We clean the seam, remove the old sealant, and apply a new bead rated for the roof’s material and slope. If the metal itself is rusted through in spots, we’ll cut out and patch that section rather than trying to seal over it.
Trusted Brands We Service in Los Angeles
We repair and install shingle brands that Los Angeles homeowners already trust, including GAF, CertainTeed, Owens Corning service in Los Angeles, Atlas, and Tamko. For tile roofs, we work with Boral products, which gives us solid options for color-matching older Spanish Colonial and Mediterranean homes. We keep common materials and flashing in local stock, so most Los Angeles repairs don’t wait on a special order. When you call, we’ll tell you whether your existing roof material is available locally or needs a match order.
Common Roof Repair Problems We See in Los Angeles Homes
- Salt-corroded flashing near the coast. The same ocean air that keeps Los Angeles cool eats through galvanized flashing and fasteners. Leaks around vents, skylights, and chimneys within three miles of the beach are almost always corrosion-related.
- Santa Ana wind damage on hillside homes. Homes on the windward side of ridges take a beating every fall. Shingles nailed with the wrong pattern or too few nails lift first, and once lifted, they never re-seat properly.
- Sun-baked underlayment in the Valley. Woodland Hills, Encino, and Sherman Oaks get more sustained heat than most of the city. Underlayment there dries out and cracks years before the shingles above it fail, which means leaks show up while the roof still looks fine from the ground.
- Flat roof leaks in older apartments and Spanish-style homes. Built-up roofs on West Adams and Mid-City buildings fail at seams and penetrations. Winter rains expose these leaks fast, and they get worse every season if left alone.

FAQs About Roof Repair in Los Angeles
Santa Ana winds hit the north and west-facing slopes of the Valley hardest, lifting shingles that weren’t nailed to the correct pattern. If your Roof Installation in Los Angeles used too few nails per shingle or the wrong nail placement, the wind finds it. After a wind event, we inspect the entire roof, not just the section you can see from the street, because lifted shingles often sit flat until the next big gust. Call (213) 521-8272 for an inspection and written repair quote.
It can. If your repair exposes decking or underlayment on a hillside home, Los Angeles building code may require bringing those layers up to current fire-resistant standards before we can close the roof. That’s why we inspect first and write any code-required work into the estimate before we start. You’ll know the full scope and price in writing, not after we’ve opened the roof.
Yes, but original 1920s clay tiles are not something you can pull off a shelf. When we encounter cracked or missing vintage tile, we color-match a modern Boral tile and blend it with the surrounding originals. It won’t be a perfect historical match, but it will be close, and it will last. We’ll show you samples before ordering anything.
Flat roofs in older Los Angeles neighborhoods like West Adams usually fail at the seams and penetrations, where the built-up membrane has been patched repeatedly without addressing the underlying edge details. Winter rains find every small separation. We strip back the failed material, inspect the decking underneath, and rebuild the seams and flashing so the repair doesn’t just move the leak to a new spot.
Small, spot repairs that don’t change the roof’s structure generally don’t require a permit. Anything that involves replacing decking, changing the roof’s fire rating, or moving into code-required upgrades may. We’ll tell you during the inspection whether a permit is needed and handle the paperwork for you if it is.
