CertainTeed Roofing in Commerce, CA | Select Roof Repair
We’re an independent CertainTeed service provider covering Commerce, CA. Most of our CertainTeed work here splits between flat and low-slope residential roofs on mid-century stucco homes and large flat commercial membranes on the city’s warehouse stock. That mix means we carry parts and materials for both, so a property manager with a leaking Flintlastic SA roof and a homeowner with granule loss on Landmark shingles get the same fast response. Call (855) 382-0485 for a free estimate.
Why Commerce Residents Choose Us for CertainTeed Service
CertainTeed builds a wide product range, and we’ve worked with most of it: Landmark architectural shingles, Presidential Shake, Flintlastic SA self-adhered modified bitumen, and Matterhorn metal roofing. Our crews know how each line behaves under Commerce’s inland heat, where south-facing slopes bake from June through October and flat membranes dry out faster than homeowners expect. Noel Carrasco, our owner, has spent 25 years fixing roofs across the LA basin, including CertainTeed service in Maywood, and built Select Roof Repair on a simple idea: most leaks are misdiagnosed the first time. We treat every CertainTeed inspection as a diagnosis, not a sales pitch. Start with an inspection, then decide.
Because we work exclusively on roofing and carry products from seven manufacturers, including CertainTeed, our recommendation is driven by what your roof actually needs. Not by what we happen to stock. That’s the whole point of being independent. We can repair a Flintlastic SA membrane on a Commerce flat roof without pushing you toward a full replacement if the membrane still has serviceable life. And when replacement is the honest call, we’ll tell you that too. Repair when it makes sense. Replace when it doesn’t. For broader coverage, see our CertainTeed sales & service page.

Common CertainTeed Roofing Problems We Solve in Commerce
- Granule loss and curling on Landmark shingles. Commerce’s summer heat bakes south-facing slopes. We regularly see Landmark shingles on homes near the Citadel outlet area with severe granule shedding and curling after 12 to 15 years. The fix is often localized shingle replacement with new underlayment and improved ventilation, which we did on a mid-century stucco home near the Citadel with exactly that failure.
- Ponding water on Flintlastic SA flat roofs. Low-slope residential roofs in Commerce’s older tracts collect water after winter rain. If drainage is poor, ponding accelerates membrane breakdown. We patch the membrane and address the drainage issue so the repair lasts.
- Dried-out elastomeric coatings on flat and low-slope roofs. The inland sun here is relentless. Coatings on both homes and commercial roofs chalk and crack, then water finds its way in. We recoat or repair based on what the substrate tells us.
- After-hours leaks on warehouse roofs. Commerce’s industrial buildings run freight operations around the clock. A leak over a loading dock can’t wait until Monday. We handle after-hours and weekend service calls for property managers, which is a big part of our CertainTeed flat-roof work here.
- Failed ridge vents and starter strips. We use genuine CertainTeed accessories for repairs: ridge vents, starter strips, and matching hip and ridge shingles. Mixing aftermarket parts where they matter creates weak points. We don’t do that.
If it’s leaking, it’s telling you something. Let’s figure out exactly what.
CertainTeed Service in Commerce: What Local Conditions Mean for Your Roof
Commerce is not a typical residential roofing market. This city is small, dense with warehouses and freight operations, and its housing stock is mostly older single-story stucco homes with low-slope or flat roofs. A roofer working Commerce is as likely to be on a TPO membrane over a freight facility as on a residential roof. That’s not the mix you’d get in a residential neighbor like CertainTeed in Bell. For CertainTeed owners, this shapes everything. The commercial side means many of our CertainTeed leak calls come from property managers who need after-hours or weekend service because their building runs on a schedule that doesn’t stop at 5 p.m. The residential side means mid-century homes with flat roofs that have been patched, recoated, and patched again, often with the wrong materials. We carry both residential shingle inventory and commercial membrane repair materials in our service vehicles, so we’re not running back and forth across the 5 and 710 freeways for parts. That’s what serving Commerce actually looks like.
CertainTeed Models & Products We Service in Commerce
We service the full range of CertainTeed roofing products common in Commerce:
- Landmark Architectural Shingles – the most common residential shingle we repair and replace on Commerce homes.
- Presidential Shake – heavier profile shingles that require careful handling; we stock matching accessories.
- Flintlastic SA – self-adhered modified bitumen, very common on Commerce’s flat and low-slope roofs. We patch, repair, and replace this membrane regularly.
- Matterhorn Metal Roofing – mostly on commercial and some residential buildings; we handle repairs and metal roof coating.
For parts, we use genuine CertainTeed accessories where system integrity matters: ridge vents, starter strips, and matching hip and ridge shingles. For repairs where OEM isn’t critical, we use quality aftermarket membranes and fasteners. The call is always based on what will perform best on a Commerce roof, not what’s cheapest on a shelf.

FAQs – CertainTeed Roofing in Commerce
Can you repair CertainTeed Flintlastic SA membrane on a flat roof in Commerce?
Yes, we patch and repair Flintlastic SA regularly. The repair involves cleaning the membrane, priming, and applying a compatible patch. We assess whether the surrounding membrane still has serviceable life before recommending a patch versus a larger replacement. Call (855) 382-0485 for an exact quote.
What causes CertainTeed shingles to fail early in Commerce?
Commerce’s intense inland sun and heat are the main culprits. South-facing slopes absorb direct sun for 10 to 12 hours a day in summer, which accelerates granule loss and causes the asphalt to dry and curl. Poor attic ventilation makes it worse. We address ventilation when we repair or replace shingles so the new roof doesn’t age the same way.
Do you offer metal roof coating for CertainTeed Matterhorn roofs on warehouses?
Yes. We apply metal roof coating systems to Matterhorn roofs on Commerce’s commercial buildings, which helps reflect heat, seal minor leaks, and extend service life. The coating system depends on the metal condition and existing finishes. A free inspection tells us what’s needed. Call (855) 382-0485 to schedule.
How do you handle after-hours leak calls for commercial CertainTeed flat roofs?
We take after-hours and weekend calls for commercial flat roof leaks in Commerce. Warehouse and freight operations in this city run on tight schedules, and a leak over inventory or a loading area can’t wait. Call us at (855) 382-0485 and we’ll get someone out as soon as possible.
Are CertainTeed organic-mat shingles still repairable, or should they be replaced?
CertainTeed discontinued organic-mat shingles years ago. If your Commerce home still has them, they’re well past their service life and we recommend replacement. Localized patching is possible but rarely cost-effective, because the surrounding shingles are equally brittle and will fail soon. Call (855) 382-0485 for a free inspection and replacement quote.
