We’ve worked Lomita’s streets since 1984. We know the post-war ranches along Narbonne Avenue, the bungalow courts off Lomita Boulevard, and the tucked-away neighborhoods near the Palos Verdes border where the marine layer sits heaviest. That local knowledge matters when you’re tearing off a roof and need to anticipate what’s underneath.

Our Roof Replacement & Installation Services in Lomita
Full Roof Replacement
Most Lomita homes were built between 1945 and 1965 with low-pitch gable or hip roofs, short overhangs, and wood rafter decking. Many have had one or two re-roofs layered over original construction. When we tear off, we regularly find deteriorated OSB or skip-sheathing beneath the surface materials. We do not cover that up. We replace it, photograph the condition, and move forward with a roof built to last. A typical full replacement on a 1,400-square-foot Lomita ranch runs $14,000-$22,000 for architectural shingles, $22,000-$35,000 for standing-seam metal.
New Construction Roofing
While Lomita is largely built out, we still handle additions, ADUs, and the occasional teardown-rebuild on the city’s scattered larger lots. We coordinate with Los Angeles County building officials, pull permits, and install to current Title 24 cool-roof requirements. For new construction in Lomita, we typically specify materials rated for high-salt marine exposure.
Asphalt Shingle Roofing
Asphalt shingles remain the practical choice for most Lomita homeowners, and we are authorized installers of GAF, CertainTeed, and Owens Corning systems. In this salt-air environment, we pay particular attention to starter strip placement and drip-edge corrosion resistance. Standard three-tab shingles in Lomita show edge wear faster than inland cities. We typically recommend architectural or designer shingles with enhanced sealant strips for Santa Ana wind resistance.
Metal Roofing
Metal roofing is gaining ground in Lomita for its longevity, but harbor-proximity salt air demands proper material selection. We install aluminum and zinc-coated steel systems, never bare galvanized products that will corrode within a decade. Standing-seam metal on a Lomita home runs $24,000-$38,000. The payoff is 40-60 years of service with minimal maintenance.
Flat Roofing
This is where Lomita’s housing stock gets interesting. Roofers working Lomita’s older tracts frequently encounter detached garages and 1950s-era room additions with near-flat built-up tar-and-gravel roofs behind parapet walls. Decades of thermal cycling crack the membrane and clog the single interior drain, creating chronic ponding that silently rots the wood blocking at the parapet base. On a 1956 ranch house near Narbonne Avenue, we replaced a failing original built-up roof with a GAF Liberty SBS-modified bitumen system. The homeowner noted their detached garage had a ponding flat roof behind a parapet; we recored the drain and installed new tapered insulation to eliminate standing water, all in one trip with our heavy-duty flatbed service truck. Flat roof replacement in Lomita typically runs $8,500-$16,000 depending on square footage and insulation needs.
Tile Roofing
Some Lomita homes, particularly those on the hillside fringes near Rolling Hills Estates, carry original clay or concrete tile. We handle tile replacement, underlayment renewal, and structural reinforcement where decades of marine-layer moisture have compromised the decking below.

Trusted Brands We Service in Lomita
We are authorized installers for seven manufacturer lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Lomita’s salt-air conditions, we typically specify GAF’s Timberline HDZ with StainGuard protection or CertainTeed’s Landmark PRO, both of which carry enhanced warranties when installed by certified contractors like Ridgeline. We stock common accessories locally, which means faster turnaround on Lomita jobs and no waiting on specialty drip edge or vent flashing. Every material is documented by batch number for warranty registration.
Common Roof Replacement & Installation Problems We See in Lomita Homes
- Salt-air corrosion of metal components. Lomita sits only 3-4 miles northeast of the Port of Los Angeles/Long Beach complex. Salt-laden marine air accelerates corrosion of metal flashing, fasteners, and drip edges far faster than in landlocked neighbors like eastern Torrance. We regularly find rust-compromised penetrations and failed step flashing during inspections, often before the shingles themselves show wear.
- Ponding on built-up flat roofs behind parapet walls. That 1950s garage addition or rear room extension with a near-flat roof and single interior drain? The drain clogs, water stands, and the wood blocking at the parapet base rots silently. By the time you see a stain inside, the damage is extensive.
- Warped plywood decking from chronic marine-layer moisture. Lomita’s post-war ranch homes often have low-slope roofs with plywood decking that warps under persistent dampness, worsened by salt-laden air from the harbor. This condition is invisible from the ground and frequently missed by inspectors who do not walk the roof.
- Improper fastener corrosion leading to blow-offs. Santa Ana winds put serious uplift stress on aging or improperly fastened shingles. When fasteners have corroded in salt air, entire courses can lift. We see this most often on low-slope decks where wind gets better purchase.

FAQs - Roof Replacement & Installation in Lomita
Salt-laden marine air from the Port of Los Angeles, just 3-4 miles southwest of Lomita, deposits chloride on metal surfaces at concentrations measurably higher than landlocked areas like eastern Torrance. This accelerates galvanic corrosion of steel fasteners, aluminum drip edges, and copper flashing, typically showing damage within 5-7 years instead of 15-plus inland. We specify marine-grade materials and heavier-gauge metals for Lomita installations. Call (877) 367-1429 for an inspection - estimates are free.
Yes, it is one of the most common failure points we see in Lomita. That construction detail - near-flat built-up roofing behind a parapet with a single interior drain - was standard for South Bay post-war additions. Decades of thermal cycling crack the membrane, the drain clogs with debris, and ponding water rots the wood blocking at the parapet base before you ever see an interior leak. We address this with recored drains, tapered insulation to eliminate standing water, and modern modified bitumen or TPO membranes. Call (877) 367-1429 - we can inspect and quote same week.
You cannot tell from the ground, and even attic inspection often misses it. Warped or delaminated plywood decking from chronic marine-layer moisture is only visible once the old roofing is removed. That is why we include decking assessment in every tear-off quote, photograph the condition, and replace compromised sheets before installing new materials. If you are planning a re-roof, call (877) 367-1429. We will walk your roof and give you an honest assessment of what we expect to find underneath.
We do not install garage door openers or springs. Ridgeline Roofing Co. handles roof replacement, repair, and related exterior systems only. For garage door service in Lomita, we can refer you to a trusted local specialist we have worked alongside for years. For your roof, flat roof, or gutter needs, call (877) 367-1429.
Not if the new roof is installed flat. Ponding is a drainage problem, not just a membrane problem. We fix chronic ponding by installing tapered insulation to create positive slope toward the drain, recoring or replacing the drain assembly, and ensuring the parapet wall allows proper overflow. Simply laying new material over the same flat surface guarantees the same standing water and the same eventual rot. A proper flat roof replacement in Lomita, done this way, runs $8,500-$16,000. Call (877) 367-1429 for a specific quote on your addition.
