Fast, Reliable Roof Replacement Across Lomita
If you own a home in Lomita, chances are your roof is the original one from the 1940s, 50s, or 60s, and it’s telling you something. Roof replacement in Lomita usually costs between $9,500 and $18,000 for a typical single-story bungalow, depending on what we find once the old shingles come off. We work throughout the 90717 grid regularly, so we know exactly what those older low-slope roofs hide under the surface. Call us at (833) 467-4901 and we’ll walk the roof with you before you spend a dime.
Our Roof Replacement team has one job here: get your Lomita home weather-tight for the marine layer and the next three decades. We don’t sell you a roof. We inspect first, tell you what’s actually failing, and then match the material to the roof’s needs and your budget, not the other way around.
Why Huntington Beach Roofers Is Lomita’s Preferred Roof Replacement Company
Lomita is a specific kind of market. The homes are older, the lots are tight, and the fog rolls in every morning from the coast. A roofing crew that only does new construction in master-planned communities will struggle on a 1950s minimal-traditional ranch with a shallow-pitch roof, a patio enclosure, and a furnace penetration that’s been leaking since Reagan was in office. We spend our time on those roofs.
Neil Stratton leads our installation crews, and he’s the person who walks every Lomita job before pricing goes out. That single point of contact from inspection to final shingle means no hand-offs, no “the estimator said one thing and the crew did another.” You get one name, one phone call, one accountable contractor.
We carry materials from seven manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That’s not a marketing bullet. It means when a Lomita homeowner needs a specific shingle to match an insurance claim or a historic overlay requirement, we’re not limited to whatever one brand’s distributor had in stock that week. Seven brands. One contractor.

Roof Installation in Lomita
Roof Installation in Lomita often means something different than it does in new-construction markets. Here, we’re not sheathing a fresh truss package. We’re tearing off a roof that’s been on the house since Eisenhower, then rebuilding the decking, flashing, and ventilation so it actually works. A full tear-off and re-roof on a 1,200 to 1,600 square foot Lomita bungalow typically runs $9,500 to $14,500, with the final number driven by decking condition and the shingle line you choose.
Decking and Framing First
Because Lomita’s 1940s through 1960s bungalows were often built with 2×4 rafters at 24-inch centers and skip-sheathing under low-slope roofs, a roof replacement here frequently requires adding solid decking and upgrading framing before any underlayment goes down. That step is rare in neighboring newer cities like Torrance’s westside subdivisions or Manhattan Beach’s remodels. We price it honestly in the initial quote when we can see it, and we walk you through any change the minute we uncover it.
Ventilation and Drip Edge Details
The marine layer keeps Lomita roofs damp longer than inland roofs, so we pay close attention to attic ventilation. We’ll cut ridge vents, add intake baffles, or install new box vents depending on how your original roofline was built. Drip edge goes on every eave and rake, because without it the onshore winds drive water behind the fascia board and into the soffit.
Roof Replacement Contractor in Lomita
A Roof Replacement Contractor in Lomita has to think about what’s under the shingles, not just what’s on top. We provide written line-item quotes that call out decking, underlayment, flashing, and ventilation separately, so you’re not staring at a single lump-sum number with no idea what’s inside it. Architectural shingle replacements on Lomita homes typically land between $10,500 and $16,000 depending on roof complexity and the brand you select.
Full Tear-Off and Replacement
We don’t do over-lays. Lomita codes and common sense both say a second layer of shingles on a roof that’s already sagging between rafters is a losing bet. Full tear-off lets us see the deck boards, fix the valleys that trap fog moisture, and lay down a clean system with proper underlayment and fasteners.
New Construction and Add-On Roofs
When a Lomita homeowner adds a bedroom or encloses a patio, the new roof section has to tie into the old one correctly. We flash the intersection with step flashing and ice and water shield so the onshore winds that hit the back of your house after 3 p.m. can’t drive rain into the wall cavity. These intersection points are where most roof leaks on older Lomita homes actually start.
Trusted Brands We Service in Lomita
We install and service roofing systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. In Lomita specifically, we keep a local stock of common GAF Timberline colors, Atlas Pinnacle shingles, and CertainTeed Landmark components so a repair or replacement doesn’t stall waiting on a distributor run. If you’re filing an insurance claim and your carrier requires brand-specific documentation, we can provide the manufacturer spec sheets and installation records the adjuster asks for. Roof Replacement in Lomita customers get the full portfolio, not a take-it-or-leave-it single-brand pitch.

AfterCommon Roof Replacement Problems We See in Lomita Homes
- Low-slope valleys that rot from the underside. The original 1950s bungalows collect debris and marine-layer moisture in the valleys, so shingles and underlayment fail from the bottom up long before the surface looks worn. We line every valley with ice and water shield and usually upgrade the decking beneath.
- Skip sheathing that sags between rafters. Old 1×6 boards spaced apart flex under foot traffic, cracking shingle mats and opening nail pops that leak during the spring fog season. The fix is solid OSB sheathing over the entire field before underlayment goes down.
- Improper flashing at additions and patio enclosures. A 1960s patio enclosure tacked onto the original footprint often meets the main roof with nothing but caulk and hope. Onshore winds push rain under those joints and into the wall cavity. We tear off the bad flashing and rebuild it with step flashing and peel-and-stick membrane.
- Furnace penetrations leaking fog moisture. Older Lomita homes vent furnaces straight up through the roof with a simple collar. Over decades, the collar rusts, the boot cracks, and the morning fog drips into the hallway ceiling. We flash every penetration with a lead boot and seal it down properly.

FAQs About Roof Replacement in Lomita
We tear it out and replace it with solid 7/16-inch OSB decking across the entire roof field before any underlayment goes down. The old 1×6 skip boards don’t provide a solid nailing surface for modern architectural shingles, and they sag between rafters on the wide spacing common in Lomita’s 1950s framing. The cost for full re-decking runs $75 to $110 per 4×8 sheet, including material, labor, and disposal, and we price it as a line item in the quote. Call (833) 467-4901 for an exact number on your home.
If we open the roof and find damaged rafters or joists, the permit will require us to repair or reinforce them to current code before we close the roof back up. In practice, Lomita’s older bungalows with 2×4 rafters at 24-inch centers often need some sistering or blocking added, especially under valleys and around penetrations. We document everything for the inspector, and any required framing work is priced and approved in writing before we touch it. The permit process adds a few days to the timeline, but skipping it means you own the risk on resale and insurance.
Architectural shingles with a strong algae-resistance rating, like GAF Timberline HDZ with StainGuard or CertainTeed Landmark with StreakFighter, hold up best in Lomita’s damp coastal air and heavy morning fog. We don’t install 3-tab shingles on Lomita roofs because the shallow pitch and moisture load crack them faster than inland. The specific brand we recommend depends on your roof’s pitch, your budget, and whether an insurance claim specifies a product. Call (833) 467-4901 for the honest answer after we look at your roof.
On Lomita’s built-out 90717 grid, many homes sit eight feet or less from the neighbor’s property line. We stage materials on the driveway and street parking with the city’s permission, use tarps and plywood to protect your landscaping and your neighbor’s fence, and run a magnet sweep daily around the entire perimeter. Our crews have done enough Lomita jobs that we know which streets allow dumpster placement and which require a shorter container. No debris ends up in your neighbor’s yard.
It starts with a free inspection where we walk the roof, check the valleys, and look in the attic to see the decking and framing from underneath. Then you get a written quote with line items. If we suspect decking or framing problems, the quote includes allowances for what we expect to find. Once work starts, we tear off the old roof, replace or repair the decking, install underlayment and flashing, shingle it, and finish with ventilation and drip edge. Most Lomita bungalows take 3 to 5 working days from tear-off to final cleanup. Call (833) 467-4901 to schedule the free inspection.
