Fast, Reliable Roof Replacement Across Lomita
Roof replacement in Lomita means working on homes built between the 1940s and 1960s, where shallow-pitch bungalows and original low-slope patio sections need a contractor who understands mid-century South Bay construction before the first shingle comes off. We’re Seacrest Roofing, and we’ve spent years opening up these older Lomita roofs to find what’s actually failing underneath, usually long before the shingles tell you there’s a problem. If you’re a homeowner in the 90717 zip code wondering whether to repair or replace, call us at (855) 597-2817. We’ll tell you exactly what your roof needs and show you every material option that fits, from budget-tier shingles to high-wind architectural lines.
Why Seacrest Roofing Is Lomita’s Preferred Roof Replacement Company
Lomita homeowners tend to ask sharper questions than most. They know their homes are older, they know the marine layer sits on their roofs every morning, and they want a contractor who can explain what that means for the decking, the fascia, and the ventilation, not just hand over a per-square price. That’s the kind of conversation our team led by Noel Chambers has with Lomita customers every week. We’re not pushing one shingle brand or steering you toward replacement when repair makes more sense. Our material-neutral inspection process diagnoses the actual problem first, then matches the product to the roof, not the other way around.
Seacrest Roofing is an authorized installer for seven shingle manufacturers, including GAF, CertainTeed, and Owens Corning. That matters in Lomita because HOA requirements, shallow-pitch conditions, and your own budget all pull in different directions. We carry the full lineup, so you choose based on what’s right for your bungalow, not what happens to be in stock. And because inspection, repair, and full replacement are handled by the same team, there’s no gap between who finds the problem and who fixes it. One contractor from first look to final nail.
Our crews are in Lomita regularly, not passing through from a distant depot. We know the streets off Narbonne, the neighborhoods near Lomita Park, and the tight access conditions on compact postwar lots. That local familiarity shows up in how we sequence tear-off, where we stage materials, and how we protect your neighbor’s property line when the roof is only a few feet away.

New Roof Installation in Lomita
New roof installation in Lomita means tearing off the old roof down to the decking, then rebuilding the whole system: decking repair where needed, new underlayment, flashing, shingles, and ventilation. It’s not a re-cover, not a patch job. It’s the full replacement that most mid-century bungalows in Lomita are due for, because the original roof from the 1950s or 1960s has outlived its design life by ten or fifteen years. A typical new roof installation on a Lomita postwar home runs from $9,000 to $15,000 depending on square footage, shingle grade, and what our inspection turns up when we open the decking. Architectural shingles from brands like CertainTeed or Owens Corning sit near the higher end because they last longer and resist wind uplift during Santa Ana events, but we have options at every budget tier.
When Full Replacement Beats Another Repair
If your Lomita roof has had two or more leak repairs in the last five years, or the shingles are curling and losing granules across the entire square, a new roof installation is usually the cheaper path over the next decade. The marine layer rots north-facing eaves and fascia slowly, and once that rot spreads under the shingles, patching becomes a losing game. We’ll show you the condition of the decking in writing, with photos, so you’re making the call with your own eyes, not just our word.
Ventilation Upgrades That Protect the New Roof
Original mid-century attic ventilation in Lomita is minimal. Many homes we open up have no ridge vent and barely any soffit intake, which means heat builds up under the shingles and shortens their life. We include ridge vent and soffit intake upgrades in our new roof installation quotes as standard, because a new roof without better airflow is just a new roof that ages too fast.
Reroofing in Lomita
Reroofing in Lomita is a full tear-off and replacement using the existing roof structure and, in many cases, keeping the original shallow-pitch and flat patio sections that are so common on these mid-century homes. A reroof is what most Lomita homeowners actually need, because the framing is still sound but the shingles, underlayment, and flashing have reached the end of their useful life. For a typical 1,200 to 1,600 square foot postwar bungalow, a reroof in Lomita typically runs $8,000 to $14,000 before decking repairs are factored in. The wildcard is always what’s hidden at the eaves and around penetrations, which is why our quote includes written allowances for decking replacement and drip edge upgrades rather than a vague promise that the price won’t move.
Hidden Rot, Written Allowances
Because Lomita’s compact postwar lots often have shallow-pitch and flat patio sections that stay in place during a re-roof, the real scope surprise is usually not the shingles but the hidden dry-rot at eaves and north-facing fascia caused by marine-layer damp, damage that never shows up in Torrance’s drier inland tracts. We inspect before we quote, and we write per-sheet pricing for decking and per-foot pricing for fascia into the contract. If we open the roof and find rot, the price for that repair is already agreed. No surprises, no renegotiation at the tear-off stage.
Keeping the Flat Patio Section
Many Lomita homes have a flat or nearly-flat patio cover section that was originally done in roll roofing or built-up asphalt. During a reroof, we can often keep that section functional by re-coating and re-flashing it rather than replacing it, which saves thousands. What we won’t do is cover it with the same steep-slope shingles as the main roof, because that’s a guaranteed leak at the transitions. Low-slope sections need their own materials and their own flashing details.
Trusted Brands We Service in Lomita
Seacrest Roofing stocks and installs across seven major shingle brands, and for Lomita customers that means real choice on warranty tier, aesthetic, and price. Whether you want the wind-rated performance of GAF architectural shingles for Santa Ana season, the color selection of CertainTeed to match your bungalow’s original character, or the value-driven Owens Corning lines, we can put a sample on your driveway before you commit. We’re not a single-line dealer, so the recommendation you get is based on your roof, your HOA rules, and your budget, not our inventory. Manufacturer warranty programs are available across the brands we install, including enhanced labor-and-material coverage at multiple price points. Call us at (855) 597-2817 and we’ll bring the samples to you.

AfterCommon Roof Replacement Problems We See in Lomita Homes
- Marine-layer rot at north-facing eaves. Morning damp lingers longest on the north slope, and on Lomita bungalows that’s where we find rotted fascia and soft decking years before the shingles themselves give out. The damage sits outside the original bid, which is why our contracts include written allowances for decking and drip edge replacement.
- Skip-sheathing under three-tab shingles. Homes built in the 1940s and 1950s often have spaced board decking rather than solid plywood, and modern shingle nailing patterns don’t always land on the gaps. Our roof replacement in Lomita includes re-nailing or overlay sheathing where skip-sheathing makes the new roof vulnerable.
- Shallow-pitch sections done wrong. Flat patio sections and low-slope transitions get covered with the same steep-slope shingles as the main roof, leaving no proper low-slope membrane or flashing, and the leaks start at the transition line. We re-flash and re-coat these sections rather than shingle over them.
- Minimal attic ventilation from the original build. The mid-century Lomita homes we replace roofs on rarely have ridge vent or adequate soffit intake, so the new shingles cook from underneath on hot afternoons. Adding ridge vent and intake is a standard part of our replacement scope, not an upsell.
Pricing for Roof Replacement in Lomita, CA
A full roof replacement in Lomita typically runs $9,000 to $15,000 for a standard postwar bungalow between 1,000 and 1,600 square feet, using architectural shingles.

FAQs About Roof Replacement in Lomita
Because the marine-layer damp that settles on Lomita roofs every morning rots north-facing fascia and eave decking years before the shingles fail, and that damage sits hidden until tear-off. A contractor who doesn’t inspect for it, or who writes a quote without allowances, will hit you with a change order mid-project. We handle it differently: inspection first, per-sheet and per-foot prices written into the contract, and any rot found is approved in writing before we touch it. Call (855) 597-2817 for a quote built on what’s actually under your shingles.
Most postwar bungalows in Lomita are 1,000 to 1,600 square feet of living space, which means 12 to 18 roofing squares depending on the pitch and overhangs. Some homes with large flat patio sections add another 3 to 6 squares of low-slope membrane to the scope. Our quotes break out the steep-slope shingle squares from the flat section work so you can see exactly what you’re paying for. Call (855) 597-2817 and we’ll measure your roof precisely.
Yes, Lomita requires a permit for full roof replacement, and the city enforces current building code on the work. For older mid-century homes, the permit often triggers requirements like sheathing fastening upgrades, drip edge installation, and in some cases the addition of positive attic ventilation. That’s not a penalty, it’s an upgrade that extends the life of your new roof, and our estimates include the cost of code compliance so you’re not surprised when the inspector signs off. We pull the permits and schedule the inspections for you.
Yes, architectural shingles from GAF, CertainTeed, Owens Corning, and the other lines we install carry wind ratings up to 110 or 130 mph when properly nailed to a solid deck. The key for Lomita homes is the decking and fastener upgrade, because skip-sheathing from the 1950s was never designed for modern wind-load nailing patterns. Our replacement scope addresses the decking first, so the wind rating on the shingle label actually means something on your roof. Call (855) 597-2817 for a quote that includes the fastener and decking work, not just the shingles.
Yes, in most cases we can keep the flat patio section and re-coat it with an appropriate low-slope membrane rather than replacing it, which typically saves $2,000 to $4,000 depending on the size. We inspect the decking and edge flashings on that section first, because if marine-layer rot has worked its way in, patching won’t hold. On a 1952 bungalow near the corner of 255th Street and Narbonne Avenue, our crew stripped three-tab shingles over skip-sheathing and found rotted fascia along the north slope plus two soft decking panels around a plumbing penetration. We documented the rot, wrote a change order with a per-sheet price for decking replacement and a drip edge upgrade, got the homeowner’s written approval, then installed new underlayment, ice and water shield in the valleys, and GAF architectural shingles with a ridge vent, finishing with the original flat patio section re-coated rather than replaced. Call (855) 597-2817 and we’ll tell you whether your patio section can stay.
