Why Van Nuys Roofing Co Is Los Angeles’s Preferred Roof Repair Company

We’re based in Van Nuys, but our trucks cover the 90036 through 90039 ZIP codes multiple times a month. Homeowners in Hollywood, Echo Park, and Koreatown keep calling us back because we inspect first and recommend second. If a roof still has life in it, we say so. If it doesn’t, we show you the photos and walk you through what’s actually failing. No brand steering, no pressure close.

We work with seven major roofing manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That matters in Los Angeles because half the city’s roofs are flat membrane systems that require specific installation methods and fire-rated detailing. Most crews push one brand they stock. We don’t care which brand you choose. We know the specs for all of them, so the product fits the roof, not our supplier arrangement.

Our Roof Repair team handles everything from emergency leak response to scheduled membrane replacement. Rick Dominguez started this company with one rule: tell the homeowner what’s actually wrong, not what’s easiest to sell. That’s why so many of our Los Angeles customers come from referrals after a neighbor got an honest answer instead of a scare quote.

Commercial Roof Repair in Los Angeles

Commercial Roof Repair in Los Angeles usually means flat or low-slope work on dingbat apartments, small office buildings, and mixed-use storefronts off corridors like Vermont Avenue, Western Avenue, and Crenshaw Boulevard. The job here isn’t shingle replacement. It’s modified bitumen, built-up, and spray foam systems that need drainage cleared, flashings re-detailed, and membranes patched to restore the fire-rated assembly. We pull up to a 1960s dingbat off Vermont Avenue where a tenant reported water through the ceiling after the first January storm. Our tech found standing water behind a single clogged scupper leaf screen, not a membrane hole. We cleared and re-set the drain, replaced the failed flashing at the parapet, and lapped a new modified bitumen patch to restore the assembly. We documented the Class A-rated layers and photographed the repair for the owner’s file so the claim referenced the restored assembly, not just a patch.

A typical commercial flat roof patch or flashing repair in Los Angeles runs $900 to $2,800. Larger membrane sections run higher. The cost depends on how many layers need to come off, whether the deck is plywood or concrete, and whether we’re matching an existing rated system or just sealing a leak. Every quote breaks out the materials, the labor, and the documentation we’ll provide if an insurer asks.

Drain and Scupper Failures

The most common commercial call we get in Los Angeles starts as a ceiling stain and ends as a clogged drain. Scupper leaf screens on low-slope roofs back up after Santa Ana wind events push debris across the membrane. Water ponds, the felt saturates, and the ceiling below takes the blame. We clear the drain, inspect the membrane for saturation, and patch what’s actually compromised. Sometimes that’s a two-hour job. Sometimes the ponding has been happening long enough that the deck is soft and the repair extends.

Parapet and Edge Flashing

Where a dingbat roof meets its parapet wall is where Los Angeles rain finds its way in. Original 1950s and ’60s flashings corrode at the counterflashing seam, and wind-driven rain pushes water sideways under the cap. We re-set flashing with proper lap and sealant, then tie the new membrane into the existing system. If the building is in a fire-exposure zone, we match the Class A assembly detail rather than just caulking the seam.

Roof Leak Repair in Los Angeles

Roof Leak Repair in Los Angeles is built around diagnosing the actual water path, not just where the stain shows up inside. On a pitched Spanish Colonial bungalow in the 90036 area, a leak near the chimney usually traces back to failed step flashing, not the shingles themselves. On a flat-roofed stucco box in Koreatown, the leak typically comes from a penetration: a vent boot, a skylight curb, an unpermitted addition’s tie-in. We find the source, open it up, and fix it right.

Leak repair costs in Los Angeles typically range from $350 for a simple vent boot or pipe flashing replacement to $1,800 for a larger flashing re-detail or membrane section repair. The price depends on what’s actually leaking. A call that starts as “water spot on the bedroom ceiling” might be a $400 flashing fix or a $2,500 membrane replacement. We won’t know until we open it up. What we won’t do is sell you a roof replacement for a $400 problem.

Vent Boot and Pipe Flashing

The rubber boot around a plumbing vent stack or exhaust pipe cracks under LA’s ultraviolet load after eight to twelve years. Dry heat and daily thermal cycling bake the neoprene until it splits at the seam where it meets the pipe. Replacing a boot is straightforward: remove the old, set the new, seal the flange, and re-fasten. On tile roofs in Los Angeles, we have to cut and fit around the tile, which adds an hour and keeps the lines clean.

Skylight Curb and Addition Tie-Ins

Original skylights and unpermitted additions are everywhere in the 90001-90010 corridor. Many were framed and flashed by handymen decades ago, and the flashings were never re-detailed when the roof was re-coated. Water runs down the curb and into the ceiling. We rebuild the curb flashing with proper counterflashing, tie the membrane into the curb with reinforcing fabric, and make sure the detail matches what the rest of the roof’s assembly requires. That last part matters for Class A-rated assemblies in fire-exposure areas.

Trusted Brands We Service in Los Angeles

We stock and service GAF, CertainTeed, Tamko, and Boral materials across Los Angeles. When you have a Tamko modified bitumen system and need a patch that matches the existing granule color, we pull it from our local supplier in the Valley and get it to your Koreatown or Echo Park job without waiting on a freight order. Being brand-agnostic means we’re fluent in the installation requirements for each product line: Boral tile has different flashing requirements than GAF shingles, and a CertainTeed membrane patches differently than an IKO system. Your roof, your material choice. If it goes on a roof, we know it.

Common Roof Repair Problems We See in Los Angeles Homes

• Scupper and drain clogs on flat roofs: Low-slope dingbat roofs off Vermont and Western channel water toward one or two drains. When leaf screens block, water ponds, and the membrane saturates. The fix is drainage first, membrane patch second.
• UV-baked membrane seams on modified bitumen: Intense sun and daily thermal cycling bake the overlap seams until they blister and open. We cut out the failed seam, re-lap a new strip, and often apply a reflective coating to slow the next round of UV damage.
• Failed flashing at parapet walls and chimney bases: Older Los Angeles homes have corroded or improperly lapped flashings at the roof edges. Wind-driven rain pushes water sideways through these seams. We re-set with proper lap and mechanically fastened counterflashing.
• Ponded water on low-slope roofs because of uneven deck settlement: Raised foundation bungalows from the 1920s and ’30s shift over time. A roof that once drained now holds water after every storm, and the repeated saturation rots the membrane. We restore drainage slope where possible, then patch the damaged field.
