Why Lomita Residents Choose Us for CertainTeed Service
CertainTeed’s Landmark, Presidential, and Carriage House lines are solid products, but they behave differently in Lomita’s marine layer than they do inland. Ruben Ibarra, our owner, has spent the better part of three decades watching roofs take a beating from South Bay air: fog-drip on the north slopes, salt corrosion on the flashings, and sun-bake on the west exposures. We also handle CertainTeed in Torrance and nearby communities with similar coastal conditions. We install genuine CertainTeed shingles and accessories where the system calls for them, and we use quality underlayment and flashing rather than cheap substitutes. Our crews know what a 1940s Lomita tract roof does to a CertainTeed valley after forty years. We inspect the deck, the felt, the flashings, and the slope-by-slope wear pattern before we quote anything. That’s the difference.

Common CertainTeed Roofing Problems We Solve in Lomita
- Algae streaking on north and shade-facing slopes. Lomita’s marine fog keeps the cool side of your roof damp long after the sun side dries, and CertainTeed three-tab and early Landmark shingles stain black there first. We treat it, replace affected tabs, or re-roof the plane if the mat is compromised.
- Lifted and curling shingle edges near the Palos Verdes foothills. The fog-dripped planes never fully re-bond their sealant strips after damp mornings, so tabs flap and lift. We re-secure what can be saved and replace the tabs that have lost their nail line.
- Granule loss on south and west slopes. Intense South Bay summer sun ages the sun-hit CertainTeed planes faster than the shaded side. You’ll see granules in the gutters while the north slope still looks years newer. We inspect both, not just the one that looks bad.
- Fastener and flashing corrosion from salty ocean air. Lomita sits close enough to the coast that original roof nails and galvanized flashings rust through. CertainTeed shingle warranties don’t cover corroded nails, so we re-nail and replace flashing boots with stainless or better-coated materials.
- Valley and vent-boot leaks on multi-plane post-war roofs. Homes from the 1940s to 1960s often have room additions that create multiple roof planes and awkward tie-ins. Original CertainTeed underlayment dries and tears at these junctions, and that’s where water gets in. We re-lay the valleys and flash the transitions properly.
CertainTeed Service in Lomita: What Local Conditions Mean for Your Roof
Lomita sits directly in the South Bay marine-layer belt at the foot of the Palos Verdes foothills, so the north- and shade-facing CertainTeed slopes here go green with algae and lift at the edges long before the sun-hit south slopes show wear. It’s the reverse of what inland roofers expect. Roofers who mostly work east of the 110 will climb up, see the south slope looking fine, and tell you the roof has years left. But on a 90717 house, the north side may already be shedding granules and wicking moisture into the deck. That’s the first thing we check. On a post-war tract home tucked onto a small lot near the Palos Verdes foothills in 90717, our crew found the north-facing CertainTeed Landmark plane streaked black with algae and lifting at the tabs while the south slope still looked solid. We’ve seen the same pattern on CertainTeed in Rolling Hills Estates homes with similar exposure. We replaced the failed plane, re-laid underlayment and valley flashing, and left the sound sun slope in place. The homeowner paid for one side of the roof, not the whole thing. That’s how a Lomita CertainTeed inspection should work: slope by slope, not a blanket guess.
CertainTeed Models & Products We Service in Lomita
We service the full CertainTeed residential lineup: Landmark architectural shingles, XT 25 and XT 30 three-tab shingles, Presidential Shake luxury shingles, and Carriage House and Grand Manor designer shingles. Where a repair calls for matching shingles, we source genuine CertainTeed from local supply houses to keep the color match tight. If a discontinued color on an old Carriage House roof can’t be matched, we’ll say so plainly and give you options rather than promise a seamless patch that doesn’t exist. We stock common underlayment, valley metal, and flashing profiles for fast Lomita turnaround, but special-order CertainTeed colors typically add a day or two. This page covers our broader CertainTeed sales & service capabilities across the South Bay.

AfterCertainTeed Service Pricing in Lomita
Repairs on CertainTeed shingle leaks in Lomita usually run $350 to $750 for isolated flashing or valley fixes. Replacing a single failed plane on a small post-war tract roof often lands between $1,800 and $3,500 depending on square footage and how much underlayment needs re-laying.

What drives cost here: multi-plane additions, the fog-side deck damage, and whether the original 1940s-1960s underlayment is salvageable.

FAQs – CertainTeed Roofing in Lomita
Why does the shady side of my CertainTeed roof in Lomita look worse than the sunny side?
Lomita’s marine layer keeps north- and shade-facing slopes damp for hours after the sun side dries, which promotes algae growth and prevents sealant strips from re-bonding. The sunny side gets baked, not colonized. In 90717, we check the fog-dripped planes first. Call (866) 217-3967 if you want us to look at yours.
Can you match my existing CertainTeed shingles on a Lomita re-roof, or do I have to redo the whole roof?
Yes, we match genuine CertainTeed shingles and can often replace just the failed plane or valley section. Color match depends on the model and age of the shingle. If your CertainTeed color is discontinued or sun-faded beyond a clean match, we’ll tell you up front. A free estimate tells you what’s possible.
My Lomita home has a later room addition with a separate roof plane – does that change a CertainTeed job?
Yes. Post-war Lomita homes often have room additions with different pitches, older framing, and tie-in points where original CertainTeed underlayment failed first. We inspect the transition between the original roof and the addition, re-flash the junction, and quote the repair or replacement separately for each plane. It changes the labor and the material count.
Is the algae on my CertainTeed shingles a sign the roof needs replacing?
Usually no. Algae streaking is a cosmetic and moisture issue, not a structural one. It means the shingle mat is staying damp, but if the granule layer is still intact and the deck isn’t rotted, a treatment or plane replacement may be all that’s needed. We’ll inspect the deck before recommending replacement. Call (866) 217-3967 to schedule a check.
Why is fastener corrosion a concern on my CertainTeed roof near the Palos Verdes foothills?
Salty ocean air blows through the South Bay and settles on roof fasteners and flashings, accelerating rust. When nails corrode, shingles lose their hold and tabs lift even if the CertainTeed shingle itself is fine. We replace corroded fasteners with coated or stainless nails and re-flash boots and valleys as needed. In Lomita, this is one of the most common causes of leaks on otherwise healthy roofs.
