Fast, Reliable Roof Replacement Across Lomita
If you’re searching for roof replacement in Lomita, the honest first answer is this: a full tear-off on a 1950s ranch here typically runs $14,000 to $24,000, depending on size, pitch, and what we find under the old shingles. That’s the real range for this city, not a teaser number. We’re Tilehurst Roofing, part of the Kingswell family of companies founded in 2000, and we’ve been on enough Lomita rooftops to know that the shingles are rarely the first thing to fail. The salt air drifting up from the Port of Los Angeles corrodes the metal components long before the field shingles wear out, and that changes how a replacement should be quoted here. Greg Holloway leads our team, and he’ll tell you the same thing over the phone: we write the price before any work starts, and it doesn’t move unless you approve a change in writing. Call us at (945) 303-9821 and we’ll walk you through what a Lomita replacement actually costs.

- Seven shingle manufacturers on tap: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral.
Why Tilehurst Roofing Is Lomita’s Preferred Roof Replacement Company
Lomita homeowners tend to come to us after someone else let them down. Maybe a crew no-showed. Maybe the price changed at the door. Maybe a repair failed within a month. That’s the exact homeowner we built Tilehurst for. We’re not headquartered in Lomita, and we won’t pretend otherwise. Dispatch and scheduling runs through our Los Angeles office, but the crews who work on your roof are local to the South Bay and know Lomita’s housing stock cold. They know that a home off Palos Verdes Drive North carries different wind exposure than one tucked near Lomita Park, and they quote accordingly.
The Kingswell Way isn’t a slogan. It’s five steps: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. Every Lomita job gets that treatment. A written price is in your hands before a single nail is driven. If a repair fails inside the guarantee period, we return at no charge under the 365-Day Done Right Promise. And when you call at 7:30 on a Tuesday evening because water is coming through, a live person answers. Not a voicemail tree. Not a callback queue. A person.
New Roof Installation in Lomita
New Roof Installation in Lomita means starting from the roof deck up, and for most of the single-family ranch homes here, that means working around a low-slope pitch of 2:12 to 3:12. These aren’t steep roofs that shed water fast. They hold moisture longer, especially during the South Bay’s May Gray and June Gloom stretch when morning marine layer sits on rooftops well past mid-morning. Salt-laden air from the Port of Los Angeles compound sits in that dampness and eats at metal components year-round. A new installation on a Lomita home has to account for that from day one, not just in the shingle choice but in the flashings, the drip edge, and the underlayment. Typical full new roof installation on a Lomita ranch runs $16,000 to $24,000, with tear-off of existing material included.
Complete Tear-Off and Re-Deck
We don’t install over old roofing here. The 1950s and 60s bungalows in Lomita were built during a building boom, and many have had two or even three layers of shingles added over the decades. Each overlay hid problems from the layer below. When we strip it all off, we commonly find deteriorating OSB or cupped 1×6 board sheathing that needs replacement before any new roof can go down. We photograph everything, show you what we found, and the decking replacement is priced as an allowance in the original written quote, not sprung on you after the fact.
Code-Compliant Underlayment and Ventilation
Opening up a Lomita roof triggers code requirements some homeowners don’t expect. Low-slope roofs under 4:12 often require specific underlayment systems, and if the roof is opened to the deck, building codes may require adding or repairing ventilation. We price these into the quote up front and pull the permit ourselves. You don’t chase paperwork. That’s our job.
Reroofing in Lomita
Reroofing in Lomita is what we recommend when the decking is sound but the roof system above it has failed. Here’s the part that surprises most homeowners: the trigger on a Lomita reroof is often not the shingles. It’s the flashings and drip edge. Salt air from the port complex travels inland and settles on the low-slope ranch roofs throughout the neighborhood, and those thin metal edges rust through and separate from the fascia years before the field shingles show wear. You’ll see rust streaks running down from the valleys, or drip edge pulling away at the eaves, while the shingles still look passable from the street. Reroofing a Lomita home typically runs $12,000 to $19,000 when the decking underneath is intact. We always price the worst case, then charge only for what the tear-off actually reveals.
Flashing and Drip Edge First
Our reroof estimates in Lomita start with a metal inspection. We check every valley, every pipe boot, every chimney flashing, and the drip edge along every eave. On a 2:12 pitch, water moves slowly and sits against these metal transitions longer than it would on a steeper roof. When the metal fails, water gets behind it and travels laterally under the shingles. No shingle warranty covers that. Our written quote reflects what the flashings actually need, not a guess.
Built for the Marine Layer
Lomita’s flat, low-elevation terrain traps morning fog longer than the hillside communities on the Palos Verdes Peninsula. North-facing low-pitch roof planes stay damp into the late morning for four to five months a year, which is exactly what algae and moss need. A reroof on those planes needs algae-resistant shingles and proper ventilation to keep the underside dry. We spec that from the start, and we’ll explain why when we walk the roof with you.
Trusted Brands We Service in Lomita
We install shingles from seven manufacturers, so the product matches your home, not whatever happens to be on our truck. GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral are all available for Lomita roof replacements. For the low-slope ranch roofs common here, we often recommend GAF Timberline architectural shingles because they carry a strong wind rating and handle the marine layer’s algae conditions well. Atlas and Tamko both make solid algae-resistant options too. Whichever brand fits your home and budget, we source it locally for fast turnaround on Lomita jobs. You get a genuine choice, and we’ll stand behind the installation with the same written guarantee on every replacement, no matter which manufacturer you select.
Common Roof Replacement Problems We See in Lomita Homes
- Rusted valley flashings and drip edge. Port-adjacent salt air corrodes exposed metal on low-slope ranch roofs years before the shingles fail. Homeowners often mistake the rust streaks as a shingle problem, when the real failure is at the metal transitions.
- Multiple overlay layers hiding bad decking. Decades of reroofs have left many Lomita homes with two or three layers of shingles nailed over deteriorating OSB or split board sheathing. The decking problems are invisible until the tear-off starts.
- Algae streaking and moss on north-facing planes. The South Bay’s May Gray and June Gloom marine layer keeps Lomita rooftops damp for months, and the flat terrain traps that moisture. Algae-fed granules break down faster, shortening shingle life even on properly installed roofs.
- Water intrusion driven by slow drainage on 2:12 pitches. Water moves slowly across the shallow slopes of 1950s Lomita ranches, giving it time to find every seam, nail hole, and flashing gap. Damage accumulates quietly inside the roof before it shows on the ceiling.
Pricing for Roof Replacement in Lomita, CA
Here are honest numbers for Lomita’s market. A full tear-off and replacement on a modest 1,200 to 1,800 square foot ranch runs $14,000 to $24,000. A reroof with sound decking underneath runs $12,000 to $19,000. Re-decking, when the tear-off exposes bad OSB or board sheathing, typically adds $350 to $500 per 100 square feet. These ranges reflect Lomita’s housing stock: 1950s and 60s ranch homes with low-slope pitches, salt-corroded flashings, and multiple old shingle layers. The single biggest variable is what we find when the old roof comes off, and that’s exactly why we inspect first and write allowances into every quote. You’ll see the numbers in writing before we start. Call (945) 303-9821 when you’re ready for that estimate, and we’ll schedule the inspection.

FAQs About Roof Replacement in Lomita
Lomita sits just inland from the Port of Los Angeles, and the persistent salt-laden marine air corrodes metal flashings, pipe boots, and drip edge far faster than shingles wear out, especially on low-slope 2:12 to 3:12 pitches where water lingers against metal transitions. The shingles often look fine from the street, but the metal underneath has rusted through and separated. That’s the most common replacement trigger we find on Lomita ranch homes. If your shingles look decent but you’re seeing interior water stains or rust streaks at the eaves, call (945) 303-9821 and we’ll inspect the metal first, which is what actually needs checking.
Yes, a full roof replacement in Lomita requires a city building permit, and we pull it ourselves as part of every job. Opening the roof often triggers code requirements homeowners don’t anticipate: low-slope roofs under 4:12 may need specific underlayment systems, damaged decking must be repaired before reroofing, and ventilation requirements may need updating. We inspect first, price those items into the written quote before work begins, and handle all permit paperwork and inspections. Call (945) 303-9821 to schedule a free estimate and we’ll walk you through exactly what your roof will require.
A roofing square is 100 square feet of roof area, and most Lomita roof replacement quotes are priced per square, with the average ranch here being 14 to 24 squares. The per-square price you’re quoted should include tear-off, underlayment, shingles, flashings, drip edge, ventilation, and haul-away of old material. In Lomita, a realistic per-square range for architectural shingles is $800 to $1,100, but the honest quote is the one that prices the hidden decking and metal work as allowances, not surprises. Get your quote in writing before work starts, just like ours. Call (945) 303-9821 and we’ll give you a line-item price you can compare accurately.
Yes, because the 2:12 to 3:12 pitch and the South Bay’s persistent marine layer mean water moves slowly and stays on the roof longer, creating ideal conditions for moss and algae on north-facing Lomita roof planes. We spec algae-resistant shingles, install proper underlayment rated for low-slope conditions, and address ventilation so the underside stays dry. A standard steep-slope spec won’t perform the same on your ranch. Call (945) 303-9821 and we’ll explain what your specific roof plane needs before you choose your shingle color.
We offer shingles from seven manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, because a Lomita ranch with a low slope and salt-air exposure shouldn’t be limited to one house brand. For most Lomita replacement jobs, we often recommend GAF Timberline architectural shingles for their wind rating and algae resistance, but Atlas and Tamko both offer strong algae-resistant options as well. Your written quote names the specific shingle we’ll install, so there’s no bait-and-switch on material. Call (945) 303-9821 to talk through which brand makes sense for your home.
