That’s the way we’ve done it since 2000, and it’s why homeowners from Silver Lake to Westchester call (213) 521-8272 when water finds a way in.

Roof Leak Repair

Leak Repair in Los Angeles usually means tracing water intrusion through cracked flashing, worn pipe boots, or compromised underlayment. A visible ceiling stain is often several feet from the actual entry point. Our technicians start at the water stain and work upward, checking valleys, penetrations, and transitions where most leaks originate. Repair costs in Los Angeles typically run $250 to $800 depending on how far the water has traveled and how many layers need to come apart.

Water Intrusion Diagnostics

We use infrared moisture meters to find saturated decking without tearing off shingles blindly. On older Spanish tile roofs around Highland Park and El Sereno, we also check mortar caps on ridge tiles, which crack over decades of sun exposure. Written findings come with every diagnostic visit.

Flashing and Penetration Repairs

Pipe boots and chimney Flashing Repair account for more Los Angeles roof leaks than shingle failure. We replace corroded pipe collars and re-seat lifted step flashing, then seal with a manufacturer-matched compound. Every repair gets a written 365-day guarantee included at no extra charge.

Emergency Roof Repair

Emergency Roof Repair in Los Angeles is for water actively entering your home, a tree limb through the deck, or wind that peeled shingles back during a Santa Ana event. If you have a tarp on your roof or a bucket under your ceiling, call (213) 521-8272 now. A live person answers, 24/7, and we dispatch a background-checked technician with temporary protection and a written repair scope. Emergency tarping and stabilization in the Los Angeles area typically runs $225 to $450, with the permanent repair priced separately before work starts.

Temporary Weatherproofing

Our crews carry heavy-duty polyethylene and water-tight fastening systems so your interior stops taking damage within hours, not days. We document everything with photos for your insurance claim. The temporary fix is removed and replaced with a permanent repair once materials are staged.

Same-Night Response Protocol

For active water intrusion, we schedule the first available technician and send their name and photo to your phone before they leave our lot. They arrive in uniform with a photo ID badge and a containment plan. You approve the written estimate before a nail goes in.

Flat Roof Repair

Flat Roof Patch and repair in Los Angeles covers the membrane systems common on mid-century homes, apartment buildings, and commercial structures across the basin. Ponding water on a flat roof will find every seam, every seam failure becomes a leak, and every leak rots the decking beneath. Los Angeles flat roof repairs range from $400 for small membrane patches to $2,500+ for large re-seams or edge metal replacement, depending on system type and square footage.

Membrane and Coating Systems

We work on built-up roofs, modified bitumen, TPO, and PVC membranes. For older tar-and-gravel roofs, we cut out blistered sections, repair the felt layers, and re-flood the patch so it ties into the surrounding surface. Coatings are matched to the existing system so water doesn’t get trapped between incompatible materials.

Drainage and Ponding Corrections

Flat roofs in neighborhoods like Mar Vista and Culver City often hold water at low points caused by sagging deck joists or insufficient slope. We install tapered insulation or supplemental scuppers to move water toward drains. Correct drainage is the difference between a five-year patch and a twenty-year roof.

Shingle Roof Repair

Shingle Replacement and repair in Los Angeles addresses cracked, curled, or missing shingles on the composition roofs that dominate LA’s suburban streets. Sun-damaged shingles lose granules, curl at the edges, and eventually expose the fiberglass mat beneath. A typical shingle repair in Los Angeles runs $275 to $600 for isolated sections, while replacing an entire roof slope can reach $3,500 to $7,000 depending on the roof’s steepness and access.

Granule Loss and Curling Assessment

We grade your shingle condition on a three-point scale: serviceable, at-risk, or end-of-life. If only a few shingles have failed, we replace those, matching color and profile as closely as the manufacturer allows. If granule loss is widespread across multiple slopes, we’ll tell you honestly that patching won’t protect you.

Section Replacement

When an entire roof plane is shot, we quote a section replacement in writing, including underlayment, starter strips, and ridge caps. We install GAF, CertainTeed, and Owens Corning shingles, among others, and we follow each brand’s installation spec. No change orders appear later for work we should have seen on day one.

Storm Damage Roof Repair

Storm Damage Roof Repair in Los Angeles is about what Santa Ana winds and winter atmospheric rivers leave behind: lifted shingles, detached flashing, and water pushed under the eaves. After heavy wind, homeowners in the foothills often find loose tiles on the ground and bare decking on the roof. Storm-related repair costs in Los Angeles range from $300 for small wind-lift repairs to $3,000+ for water remediation and deck replacement, depending on scope.

Wind-Uplift Inspections

We check every roof plane after a wind event, not just the one you can see from the street. Our technicians flag shingles with broken adhesive bonds and tiles shifted out of position. We document everything with dated photos so your insurance adjuster sees exactly what we saw.

Insurance Documentation Support

Mercer Roofing Co Los Angeles provides written repair scopes, photo logs, and material estimates formatted for homeowners’ insurance claims. We’ll meet with your adjuster on-site if that helps move the claim. The final written price you approve is the price you pay, whether insurance covers it or not.

Metal Roof Repair

Metal Roof Repair in Los Angeles focuses on standing-seam and corrugated metal systems found on modern homes, workshops, and commercial buildings. Fasteners back out over years of thermal cycling, and water follows the loosened screw into the decking. Los Angeles metal roof repair costs typically run $350 to $1,100 for fastener replacement and sealing, while panel replacement can reach $2,500 to $5,000 depending on the panel profile and color match.

Fastener Failure and Panel Lift

We replace neoprene washers on exposed-fastener roofs and re-torque standing-seam clips where panels have lifted. Left alone, loose fasteners wallow out their holes and let water sit against the decking. On panel replacements, we match gauge, profile, and finish as closely as the current market allows.

Seam and Flashing Sealant Renewal

Metal expands and contracts more than any other roofing material. Sealant at transitions and seams fails first, especially on south-facing slopes in neighborhoods like Reseda and North Hills. We cut out old sealant, clean the joint, and re-apply a UV-stable product. Written price first, every time.

Commercial Roof Repair

Commercial Roof Repair in Los Angeles handles flat and low-slope systems on retail strips, warehouses, and office buildings from Vernon to Commerce. A small leak in a commercial roof becomes a big problem fast when it drips onto inventory or into a tenant’s space. Commercial roof repair pricing in Los Angeles starts around $700 for small membrane repairs and climbs to $8,000+ for large re-cover sections, depending on system type and access.

Tenant Improvement Roof Assessments

Before a tenant signs a lease or a building changes hands, we provide roof condition assessments with photo documentation and written repair recommendations. Property managers use these reports to plan capital improvements. We schedule around business hours and keep disruption to a minimum at your storefront or loading dock.

Long-Term Maintenance Plans

We set up recurring inspection and maintenance schedules for commercial clients in Los Angeles, Gardena, and Lynwood. Each service visit ends with a written condition report. Catching a $400 seam repair early prevents a $4,000 deck section three years later.

Brands We Service

We install and repair shingle systems from GAF, CertainTeed, and Owens Corning, and we routinely work on metal and tile profiles from Atlas and Boral. If you have a GAF roof in Los Angeles, our technicians are familiar with GAF’s Timberline profiles and can match replacement shingles to your existing color and exposure. We follow each manufacturer’s published installation specifications, which keeps your material warranty intact.

For Atlas and Boral products, we understand the differences in fastening patterns, underlayment requirements, and tile profiles that make repairs look seamless instead of patched. Whether you have Atlas, Boral, GAF, or any other make on your roof, we can inspect it, price the repair in writing, and get it done right the first time.

Signs You Need a Pro Right Now

• Water stain on your ceiling. A yellow-brown ring means water has already saturated the decking above. The longer it sits, the more sheathing you lose, and mold starts in the dark, warm space between your ceiling and the roof.
• Curled or missing shingles. Once shingles curl, they catch wind and tear off in the first strong blow. Missing shingles expose the underlayment, which only lasts so long against UV and rain.
• Granules in the gutter. If your downspouts are spitting sand-colored granules, your shingles are shedding their protective layer. That’s the first sign the roof is aging faster than the rest of the house.
• Daylight through the attic. On a sunny afternoon, look up. If you can see pinpricks of light through the decking, water will find those same openings in the next rain.
• Flashing pulling away. Metal flashing that’s lifted from the chimney or walls is an open invitation for water. A quick re-seat now costs a fraction of the interior repair later.

Our Process, Step by Step

1. 1
   Call and connect. You call (213) 521-8272 and a real person answers, day or night. We listen to what’s happening, ask a few questions, and schedule a visit. Before the technician leaves the lot, you receive their name and photo.
2. 2
   On-site inspection. The technician arrives in uniform, shows a photo ID badge at the door, and goes over what they’ll be checking. They inspect the roof surface, flashings, penetrations, and attic for signs of water that aren’t visible from outside.
3. 3
   Written diagnosis and price. We hand you a written description of the problem and a line-item price to fix it. Nothing starts until you approve the scope. If the roof doesn’t need work, we’ll tell you that plainly.
4. 4
   Repair work. Repairs are done with materials matched to your existing roof system, installed to manufacturer spec. We protect the work area and clean up debris before we leave.
5. 5
   Written guarantee. Every repair carries a 365-Day Done Right Promise in writing. If the repair fails within a year, Mercer Roofing Co Los Angeles sends a technician back at no charge. We also include a free second visit if the repair doesn’t hold.
