Fast, Reliable Roof Replacement Across Lomita
If you own a home in Lomita, your roof was almost certainly built between 1940 and 1969, and it’s probably wearing its second or third covering right now. That means the real question isn’t whether you need a replacement. It’s what’s underneath the layers that were nailed on top of each other over the decades. We’re Sunridge Roof Repair, and we specialize in exactly this kind of work: tearing off aging composition shingle and built-up flat roofs on Lomita’s ranch and Spanish-stucco homes, inspecting the decking underneath, and rebuilding a roof that can handle decades of marine-layer fog. Call (833) 589-5180 to schedule a free replacement estimate anywhere in 90717.
Why Sunridge Roof Repair Is Lomita’s Preferred Roof Replacement Company
Our crews know Lomita’s streets. We’ve worked on homes off Narbonne Avenue, along Oak Street, and throughout the tight residential blocks north of Lomita Park. What we’ve learned is consistent: the marine layer that rolls in off the South Bay coastline every morning keeps roof surfaces damp, and that dampness gets into fasteners, flashing, and decking in ways you’d never spot from the ground. We build our replacement process around that reality. We inspect before we recommend, which means we pull back sections of existing covering during the estimate to see what the last re-roof buried.
Ruben Ochoa, who leads our crews, started Sunridge with a simple rule: roofing only. No siding, no gutters, no windows. Every person on the job is a roofing specialist. That focus means we diagnose faster and give you an honest repair-versus-replace recommendation before any work is quoted. Lomita homeowners call us because they want a straight answer about decking condition and roof lifespan, not a sales pitch.

Roof Replacement Contractor in Lomita
A Roof Replacement Contractor in Lomita is doing a specific kind of job: removing every layer of existing roofing down to the original decking, inspecting that sheathing, replacing what’s rotted or delaminated, and installing a fresh covering. The work typically runs between $12,000 and $24,000 in Lomita depending on tear-off depth, decking repair scope, and material choice. On a 1,200-square-foot ranch with a single layer of composition shingle, you’re looking at roughly $10,500 to $15,500 using architectural shingles from Owens Corning or CertainTeed. Add a flat garage roof with built-up layers and failing seams, and the number shifts upward because that substrate takes more labor and new membrane.
We pull permits for every replacement in Lomita. The county requires re-roof inspections on tear-off jobs, and our crews sequence the work so the decking inspection happens before any new underlayment goes down. That’s how you avoid paying for a roof that looks new but hides the same problems underneath.
Full Tear-Off and Decking Replacement
On Lomita’s 1940s and 1960s homes, we almost always find multiple layers. Two layers is common. Three layers is not unusual on garage additions and flat roof sections. We tear off to the decking every time, because skipping that step buries rotted sheathing and corroded fasteners under new shingles. When we find soft or delaminated decking, we replace it before installing new underlayment, ice and water shield, and the top covering.
Flat Roof Sections and Attached Garages
Many Lomita homes have flat or low-pitch sections over attached garages, additions, or patio covers. Those sections often use built-up roofing or rolled composition that’s decades old. The marine layer attacks the seams and flashing first. We’re one of the few crews in Lomita that handles both steep-slope shingle work and flat membrane sections on the same job, so you don’t end up coordinating two contractors for one roof.
Asphalt Shingle Roof Replacement in Lomita
An Asphalt Shingle Roof Replacement in Lomita typically means architectural shingles on a low-pitch ranch or Spanish-style home, with a tear-off to the decking first. For a standard single-story home of about 1,200 to 1,600 square feet, the cost in Lomita runs about $11,000 to $18,000 when you’re using architectural shingles from a manufacturer like Owens Corning, CertainTeed, or IKO. Three-tab shingles run slightly less, but most Lomita homeowners choose architectural for the thicker profile and better wind rating, which matters when winter storms push wind-driven rain at the valleys and ridges.
The quote changes based on how many layers we’re tearing off and how much decking needs replacing. On homes where the original sheathing is still solid, the job is straightforward. On homes where decades of fog-dampened moss has softened the north-facing slopes, the decking repair adds $1,500 to $4,000 depending on the square footage involved.
Architectural Shingle Upgrades
Architectural shingles hold up better under Lomita’s damp conditions than older three-tab profiles. The laminated construction resists the warping and lifting we see on older three-tab roofs when the morning fog sits on the surface. We stock a broad range of colors locally, and we match existing profiles when a partial replacement doesn’t make sense as a full tear-off.
Decking and Substrate Repairs
The decking under your shingles is the foundation of the whole system. If it’s rotted, soft, or delaminated, new shingles can’t perform. On Lomita tear-offs, we always inspect the decking before new underlayment goes down. When we find rot, we replace it. You see the cost in the quote before we start, not as a change order later.
Trusted Brands We Service in Lomita
We’re brand-agnostic, which means we recommend the material that fits your home’s pitch, your decking condition, and your budget. We work with Owens Corning, CertainTeed, IKO, and Atlas, among others. If you want a premium architectural shingle with a strong wind warranty, we’ll quote CertainTeed or Owens Corning. If your budget is tighter, we’ll show you IKO or Atlas value lines that still carry manufacturer warranties. We stock common materials and components locally for Lomita jobs, so tear-off and replacement work doesn’t stall waiting on parts. Your choice of materials, backed by real brand warranties, not whatever a supplier is pushing this month.

AfterCommon Roof Replacement Problems We See in Lomita Homes
- Third-layer tear-offs exposing rotted original decking. On a low-slung ranch off Lomita’s tight residential blocks, our crew pulled three layers of aged composition shingle off the attached-garage addition and found the original decking soft where marine-layer fog had fed years of moss on the north slope. We replaced the compromised sheathing, laid new underlayment and ice and water shield through the valleys, and set GAF architectural shingles with a fresh drip edge and ridge vent so the fog could shed instead of sitting. The homeowner finally had a flat-roof-to-pitch transition that stopped the winter wind-driven rain intrusion at the flashing.
- Corroded fasteners and flashing from salt-laden fog. Lomita’s morning fog carries salt from the harbor and coastline, and it settles on every roof surface. Nails corrode, flashing at penetrations and valleys rusts, and failures start even when the shingle surface looks fine. A re-roof that doesn’t replace these fasteners just wraps the same corrosion in new shingles.
- Moss on north-facing slopes trapping moisture. The north side of a Lomita roof may never fully dry between fog cycles. Moss grows into the shingle granules and holds moisture against the underlayment. If you skip decking inspection, you’re burying that moisture under new architectural shingles, and the problem comes back faster than a roof should fail.
- Failing flat-roof seams on garage additions. Built-up and rolled roofing on attached garages looks sound from the street. Up close, the seams are where marine-layer moisture does its slow damage. We routinely find split seams, cracked flashing, and saturated substrate that only a tear-off exposes.

FAQs About Roof Replacement in Lomita
Every replacement we do in Lomita includes a full tear-off to the original decking. We don’t roof over existing layers, because that hides rotted sheathing and corroded fasteners from the last re-roof. On homes with three layers, which we see regularly on garage additions and flat sections, the tear-off takes more labor and disposal, and we account for that in the quote before we start.
The marine layer keeps Lomita roofs damp for hours every morning, and that moisture drives our material recommendations. We specify architectural shingles that resist warping and lifting better than three-tab, and we install high-quality synthetic underlayment and ice and water shield through valleys and around penetrations. That combination gives the roof a fighting chance against the fog-driven corrosion and wind-driven rain we see during winter storms. Call (833) 589-5180 for a recommendation specific to your home.
Yes. Lomita lots are narrow, and many homes have only a few feet between the house and the property line. We’ve staged tear-offs on tight side yards throughout the city, including homes off Narbonne Avenue and the blocks north of Lomita Park. We sequence the tear-off so debris comes off the roof in sections, and we use smaller dumpsters positioned carefully to avoid blocking driveways and walkways.
We can match most architectural shingle profiles and colors from the major manufacturers we work with, including CertainTeed, Owens Corning, IKO, and Atlas. That said, on Lomita homes with two or three layers already in place, a partial replacement often doesn’t make sense because the underlying layers are compromised. We’ll inspect and give you an honest answer about whether partial makes sense or a full tear-off is the better use of your money.
Look at the scope, not just the number. Does each bid include a full tear-off to the decking? Does it specify the underlayment brand and grade, the shingle manufacturer and product line, and the decking repair allowance? Does it cover the flat roof sections separately, or are they glossed over? We provide line-item written estimates that spell all of that out, so when you compare our quote against another Lomita roofer’s, you’re comparing apples to apples. Call (833) 589-5180 and we’ll walk you through the numbers.
