Fast, Reliable Roof Repair Across Lomita
Roof repair in Lomita usually costs between $350 and $1,900 depending on what’s failing, and most jobs we handle in the 90717 ZIP are done in a single visit. If you’ve spotted a water stain on the ceiling, curling shingles on the north slope, or damp drywall near the garage roofline, don’t wait. Marine fog has a way of turning small roof problems into structural ones faster than homeowners expect. Call Sunridge Roof Repair at (833) 589-5180 and we’ll schedule an inspection before recommending anything.
We know Lomita’s housing stock well because we work on it every week. The post-war ranches and Spanish-style stucco homes here, most built between 1940 and 1965, have roofs that are on their second or third covering. That means when we arrive, we’re rarely doing a quick patch. We’re usually diagnosing what’s failing underneath. Our Roof Repair team carries materials for all seven major manufacturers we work with, so we can match what’s already on your roof instead of forcing a product that doesn’t belong there.
Why Sunridge Roof Repair Is Lomita’s Preferred Roof Repair Company
We inspect before we recommend. That’s not a tagline, it’s how we work in Lomita. When you call us about a leak on Narbonne Avenue or a failing flat roof over a garage addition near Lomita Park, we start with a standalone roof inspection. We’ll walk the roof, photograph what we find, and give you a straight answer about whether this is a repair or a replacement. If it’s repair, we quote repair. If it’s not, we’ll tell you that too and show you why.
Our crews work exclusively on roofing. No siding, no gutters, no windows. That single-trade focus means our technicians diagnose problems faster and fix them correctly the first visit, because they’ve seen hundreds of roofs just like yours in Lomita and the surrounding South Bay. We carry materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so the recommendation you get reflects what your roof actually needs, not what we happen to have on the truck.
Ruben Ochoa, who leads our team, insists on two things for every Lomita job: a written line-item quote before work starts, and a clear explanation of what we found once we open things up. That matters because Lomita homes have a habit of hiding problems. Original 15-lb felt underlayment from the 1960s is often still in place under newer shingles, and it fails silently until water reaches the decking.
Styles & brands we work with






Emergency Roof Repair in Lomita
Emergency Roof Repair in Lomita usually means a winter storm has torn shingles loose, a tree branch has punctured the roof, or wind-driven rain is getting under flashing at a roof-to-wall intersection. We respond to calls throughout 90717 as quickly as the weather allows and we’ll install a qualified temporary repair, like tarping or a sealed patch, to stop active water entry the same day we arrive. Emergency response pricing in Lomita typically runs $450 to $950 for the temporary work, with the permanent repair quoted separately once the roof is dry enough to inspect properly.
Storm Damage Response
When a Pacific storm rolls through the South Bay with wind gusts over 40 mph, the roofs that take the worst damage are the older low-pitch structures with original flashing. Lomita’s older ranches have skylight curbs, vent pipes, and chimney flashings that were installed decades ago, and wind-driven rain exploits exactly those seams. We document everything with photos and provide a repair scope you can submit to your insurer if a claim makes sense.
When to Tarp vs. When to Patch
If the roof surface is wet, a tarp is the honest answer. Patching shingles onto a soaked underlayment only traps moisture and creates a bigger problem later. If we can get a dry section, a sealed membrane patch over the breech works and holds until we can return with full materials for the finished repair.
Flat Roof Repair in Lomita
Flat Roof Repair in Lomita is a regular call for us because so many homes here were built or expanded with flat built-up or rolled-roof garage additions. The marine layer sits on those low-pitch surfaces all morning, every morning, and the seams in the old membranes fail from constant dampness and salt exposure. Repair costs for a typical flat roof patch in Lomita run $475 to $1,400 depending on the size of the failed area and how much decking needs replacement underneath.
Built-Up Roof Seam Failures
Older built-up roofs fail at seams and scuppers first. We cut back the deteriorated layers, dry the substrate, apply a compatible patch material, and reseal with a membrane that matches the existing system as closely as possible. On Lomita’s garage additions, the telltale sign is efflorescence or water staining on the garage ceiling near the exterior wall.
Rolled Roof Membrane Replacement
When a rolled-roof area is too far gone for a patch, we quote a full membrane replacement for that section. We stock rolled roofing, base sheets, and adhesives from the major manufacturers, so you’re not waiting on a special order. The goal is always a seam-free, fully adhered section that will hold through the next winter storm cycle.
Trusted Brands We Service in Lomita
We work with seven major roofing manufacturers, including GAF, CertainTeed, Tamko, and Boral, which means we’re not locked into selling you one brand’s product line. If your Lomita home has builder-grade architectural shingles and you want to upgrade, we can move you into CertainTeed Landmark or GAF Timberline without changing contractors. If the budget is tighter and the roof is younger, matching your existing Tamko or Boral product keeps the repair uniform and warranty-sensible. We keep common shingle colors, underlayment, and flashing stock on hand for Lomita jobs, which shortens turnaround when you’ve got an active leak.

AfterCommon Roof Repair Problems We See in Lomita Homes
- Moss and algae on north-facing slopes. The marine layer keeps Lomita roofs damp well into the afternoon, and north slopes rarely dry fully between fog cycles. Moss holds moisture against the shingle surface, and over time that trapped moisture degrades the granules and accelerates felt rot underneath.
- Corroded nails and flashing. Salt-laden fog from the nearby harbor and South Bay coastline works its way into every exposed fastener. We routinely find nails that have lost their heads and galvanic corrosion at flashing-to-shingle joints on homes throughout 90717, especially near Lomita Pines and areas west of Western Avenue.
- Failed flat-roof seams on garage additions. The original rolled or built-up membranes on post-war garage additions are decades past their expected life. The constant morning dampness causes blisters and seam separation that leaks into the garage ceiling near the house wall.
- Deteriorated 15-lb felt underlayment. Homes built in the 1940s through 1960s often still have the original asphalt-saturated felt under any newer shingle layer. Once that felt breaks down, water that gets past the shingles travels sideways and shows up far from the actual breach.

FAQs About Roof Repair in Lomita
The first upgrades we recommend for builder-grade roofs in Lomita are replacing 15-lb felt with a synthetic underlayment when any section is opened, upgrading thin architectural shingles to a higher-weight product from GAF or CertainTeed, and swapping standard pipe boot flashings for heavier-gauge metal. Synthetic underlayment resists the same dampness that rots felt, and it adds only a few hundred dollars per tear-off section. Call (833) 589-5180 if you want a specific recommendation for your roof.
Repairs that use materials matching or exceeding what the builder installed, done by a licensed contractor who documents the work, generally do not void a roof warranty. The problems start when homeowners or handymen use non-OEM flashing, alter roof penetrations without approval, or change the roof system type entirely. We provide written documentation of every repair with photos and material specs, which is what builders and manufacturers want to see. Call us before you let anyone modify your roof.
Many Lomita neighborhoods with HOAs do require architectural review for roof changes, particularly if the repair changes the color, material type, or profile of the roof. Repairs that match existing materials are often classified as maintenance and may not require review, but we recommend checking your CC&Rs before starting. We can provide material specifications and samples to help with the approval process. Call (833) 589-5180 and we’ll walk you through what your HOA is likely to ask for.
Flat roofs on Lomita garage additions fail because the original built-up or rolled membranes were never designed for decades of salt-laden morning fog. The seams absorb moisture, the membrane blisters, and the constant damp-then-dry cycle breaks down the bitumen. By the time water shows up on the garage ceiling, the membrane has usually been compromised for a year or more. A proper repair involves cutting back to solid material, drying the substrate, and applying a compatible patch that addresses the seam failure, not just the visible split.
The first upgrade worth making is synthetic underlayment, because Lomita’s marine layer destroys 15-lb felt faster than any shingle can fail. The second is upgrading to a heavier architectural shingle, which resists granule loss and moisture absorption better than builder-grade products. The third is replacing standard flashings with corrosion-resistant metal. Each of these costs less than the full roof replacement they help delay. For an exact quote on any of these upgrades, call (833) 589-5180; estimates are free and we’ll show you what we found before recommending anything.
