CertainTeed Roofing in Lomita, CA | Huntington Beach Roofers
We provide independent CertainTeed roofing service across Lomita and nearby areas like CertainTeed in Torrance, from full re-roofs on 1940s bungalows to valley repairs on shallow-pitch additions. The thing that makes our CertainTeed work different here is the marine layer: fog sits on Lomita roofs until noon, and CertainTeed shingles on low slopes show it. We inspect first, recommend second, and handle repair or replacement start to finish. Call (833) 467-4901 for a free estimate.
Why Lomita Residents Choose Us for CertainTeed Service
We’ve been installing and repairing CertainTeed shingles and low-slope systems across the South Bay for years, so we know how their product lines age under Lomita’s fog and coastal air. We’re an independent CertainTeed service provider, not authorized by CertainTeed, and we base every repair or replacement call on what we see on the roof, not on a sales sheet. Neil Stratton leads our team, and he grew up in the Bolsa Chica neighborhood of Huntington Beach, where half the houses on his street seemed to be leaking at any given time. That turned out to be career guidance. He learned the trade through the construction technology program at Golden West College and has spent more than two decades putting that foundation to work on roofs all over the South Bay and OC coastline. Seven brands. One contractor. For Lomita homeowners, that means we match CertainTeed products to your roof’s actual condition, not to what we happen to stock. CertainTeed sales & service is part of a broader portfolio that includes GAF, Owens Corning, IKO, Atlas, Tamko, and Boral, so the recommendation follows the roof’s needs and your budget.

Common CertainTeed Roofing Problems We Solve in Lomita
The marine layer in Lomita does specific things to CertainTeed roofs, and we see the same patterns on bungalows and ranches throughout 90717. Here’s what shows up most:
- Granule loss and algae streaking on north-facing slopes. Landmark and XT 30 shingles on low-pitch Lomita bungalows often shed granules where fog moisture lingers longest. North-facing slopes stay damp into the afternoon, and that’s where black algae streaking starts. It’s cosmetic until it isn’t, because granule loss exposes the asphalt matrix to UV and shortens the shingle’s life.
- Flintlastic SA seam separation in shallow-pitch valleys. Valleys on older Lomita additions collect debris and hold fog moisture, and Flintlastic SA seams eventually lift and separate under those conditions. The leak is usually invisible until spring, when the first sustained rains after a dry stretch find the gap.
- Blistering on laminated shingles over old add-ons. Presidential Shake and other laminated CertainTeed shingles trap heat where the original attic venting was never upgraded for added roof area. On 1940s and 1950s add-ons, that heat blisters and cracks shingles long before their rated life.
- Fastener corrosion on older decking. Onshore winds and damp coastal air accelerate rust on nails and staples, especially on original decking that was never re-nailed. We find this every week in Lomita: the shingles look fine, but the fasteners have quietly failed and the roof lifts in a wind event.
- Valley flashing failures at patio enclosure tie-ins. Many Lomita homes added patio enclosures decades ago, and the flashing where the enclosure roof meets the main roof is often original. CertainTeed valley membrane or sheet metal at those transitions cracks and pulls away, and fog moisture creeps in through the gap.
CertainTeed Service in Lomita: What Local Conditions Mean for Your Equipment
Here’s what anyone doing CertainTeed work in Lomita has to understand: the 90717 grid is fully built out, and most of the homes date from the 1940s through the 1960s. That means tight lot lines, narrow setbacks, and driveways that won’t fit a full dumpster. When we re-roof a CertainTeed home near the Lomita Park area, staging shingles and tear-off debris often means working from the driveway or street with a conveyor rather than dropping a dumpster on the front lawn. It changes how we sequence the job: tear-off moves in sections, material goes up as needed, and debris comes down the conveyor in a controlled stream. The marine layer compounds it. Lomita sits in the South Bay fog belt, so roofs stay wet longer and the shingles that come off are heavier with absorbed moisture, a pattern we also see with CertainTeed in Rolling Hills Estates. On a 1950s ranch near Lomita Park, we found the original CertainTeed XT 30 on the low-slope rear addition had algae streaking and soft decking under a valley that held fog moisture all spring. We tore off the affected section, replaced the decking, and re-roofed with CertainTeed Landmark architectural shingles plus a new Flintlastic SA valley membrane, then re-flashed the patio enclosure tie-in. The homeowner said the leak that had stained the ceiling every March hadn’t come back the following spring. That’s the kind of fix that only comes from knowing how CertainTeed products and Lomita’s climate interact.
CertainTeed Models & Products We Service in Lomita
We work on the CertainTeed product lines most common on Lomita roofs: Landmark architectural shingles, Presidential Shake, XT 30, and Flintlastic SA self-adhered low-slope membrane. For repairs, we use CertainTeed OEM shingles, underlayments, and accessories when they’re available and a true match for the existing roof. For low-slope patches and flashing, we’ll use quality aftermarket membranes and metals when OEM isn’t practical or the right call. We stock common CertainTeed Landmark colors and Flintlastic SA membrane locally for faster Lomita turnaround, and we’ll tell you straight when a repair buys a few years versus when the decking or underlayment is too far gone to justify anything but replacement. Repair or replace, we’ll tell you which one actually makes sense.

FAQs – CertainTeed Roofing in Lomita
Yes, and it’s the marine layer doing it. North-facing slopes in Lomita stay damp from morning fog well into the afternoon, and that persistent moisture is exactly what algae needs to take hold on Landmark’s granule surface. The streaking is cosmetic at first, but prolonged algae growth breaks down the shingle’s UV resistance. Have it cleaned with the right approach, or plan for replacement if the shingles are past mid-life. Call (833) 467-4901 for an inspection.
Usually, yes. If the decking under the valley is sound, we can cut out the failed Flintlastic SA section, install a new membrane, and re-bed the valley with proper underlayment and flashing. If fog moisture has already rotted the decking, the repair becomes a partial re-roof. We’ll tell you which it is after we open it up. Estimates are free, call (833) 467-4901.
We use CertainTeed OEM shingles when they’re available and a true color and profile match for your existing roof. That matters on Lomita’s older bungalows, where a mismatched shingle line on a visible slope is obvious from the street. For low-slope patches and flashing, we’ll use quality aftermarket membranes and metals when OEM isn’t practical. The goal is a repair that holds and looks right, not a brand-box check.
On the built-out lots in 90717, there’s rarely room for a full dumpster on site. We stage materials on the driveway or street and run tear-off debris down a conveyor, which means the job moves in sections and the yard stays intact. It’s slower than a wide-open suburban tear-off, but it protects your landscaping and keeps the job site tight. Call (833) 467-4901 to talk through your roof’s specific access.
For most 1950s ranches, yes. Presidential Shake is a heavy laminated shingle designed to mimic wood shake, and on a low-pitch minimal-traditional roof it adds weight and cost without much payoff, especially if the original attic venting was never upgraded for the added roof area. Landmark architectural shingles typically make more sense on those homes. We’ll show you the trade-offs and let the roof’s needs drive the call. Match the material to the roof, not the other way around.
