CertainTeed Roofing in Commerce, CA | Huntington Beach Roofers
We provide independent CertainTeed roofing service across Commerce, CA, from flat commercial work near the I-5 and I-710 interchange to residential shingle repairs on the city’s tract homes. The one thing that makes our CertainTeed work here different is simple: Commerce’s roofs are overwhelmingly flat and low-slope, which means we spend far more time on Flintlastic membranes and modified bitumen than most contractors who mostly see steep shingle roofs. Call (833) 467-4901 for a free estimate. Our team handles inspection, repair, and replacement under one roof, and Neil Stratton, our owner, has spent over two decades working on Southern California roofs in exactly these conditions.
Why Commerce Residents Choose Us for CertainTeed Service
Seven brands. One contractor. We carry GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so when you call us about a CertainTeed roof—or need CertainTeed in Bell—you’re getting someone who knows exactly where that product sits in the wider market and can tell you honestly whether a repair makes sense or whether another material would serve you better. Neil grew up in Bolsa Chica in Huntington Beach, where half the houses on his street seemed to be leaking at any given time, which turned out to be career guidance. He’s been straight with homeowners ever since about what a roof actually needs. We’re an independent CertainTeed service provider, not a manufacturer-authorized contractor, so our recommendations are based on what we see on your roof, not on what a brand wants us to push. For Commerce specifically, that means we understand the flat-roof reality of this city better than most.
We inspect first, recommend second. That’s how we’ve always worked, and it’s why property managers and homeowners around Commerce call us before they commit to a full replacement. You’ll find more about our broader CertainTeed sales & service work here.

Common CertainTeed Roofing Problems We Solve in Commerce
- Flintlastic seam cracking from UV and smog exposure. Commerce sits in one of the sunniest, smoggiest pockets of the LA Basin. Intense ultraviolet light and airborne pollutants bake modified bitumen membranes, causing surface crazing and seam separation. We regularly see Flintlastic roofs with open seams that let winter rain straight through to the deck.
- Standing water at clogged scuppers and drains. On Commerce’s flat commercial roofs, the failure mode we watch for most is ponding. Debris collects at scuppers, water pools after a storm, and the deck rots quietly long before anyone sees a leak inside. We clear the drainage path and repair the membrane at the source.
- Granule loss and thermal cracking on Landmark shingles. Older tract homes in Commerce with south-facing slopes get hammered by decades of sun. CertainTeed Landmark shingles lose granules and develop hairline cracks, especially on the hottest exposures. We can replace individual shingles or a full slope, depending on how far the aging has progressed.
- Flashing failures at wall intersections and valleys. Improperly installed CertainTeed flashing is one of the most common sources of leaks on Commerce’s mixed residential and commercial stock. When debris blocks low-slope scuppers at the same time, water backs up and finds every weak flashing joint. We repair the flashing and the drainage together, because fixing one without the other just moves the leak.
- Attic ventilation deficiencies on steep-slope roofs. On the shingle roofs we do see in Commerce, poor attic ventilation accelerates curling and brittleness. We’ll check ventilation when we diagnose a CertainTeed shingle problem, because replacing shingles without fixing airflow means you’ll be replacing them again sooner than you should.
CertainTeed Service in Commerce: What Local Conditions Mean for Your Roof
Commerce’s building stock is dominated by post-World War II industrial and commercial structures, and many of those buildings still carry their original flat roofs, now decades old. That means CertainTeed Flintlastic SA and other low-slope systems are far more common here than steep-slope shingles. If you own or manage a warehouse or light-manufacturing building in Commerce, you need a roofer who thinks in modified bitumen, not someone who only does residential shingle work. Our crew recently repaired a CertainTeed Flintlastic SA roof on a 1960s warehouse near the I-5 and I-710 interchange. The membrane had cracked along the seams, and ponding water from a clogged scupper had rotted the deck edge. We removed the damaged section, replaced the decking, and installed new Flintlastic SA membrane with proper drainage, restoring the roof without a full replacement. That’s the kind of targeted work Commerce buildings need most. Tell me what the roof is doing, and I’ll tell you what it actually needs.
CertainTeed Models & Products We Service in Commerce
We work on the CertainTeed product lines that actually show up on Commerce roofs. That includes Landmark architectural shingles on the city’s tract homes, Presidential Shake where homeowners want a heavier wood-shake look, Independence Shingles on budget-conscious replacements, and Flintlastic SA, the self-adhered modified bitumen membrane we see on flat commercial and industrial buildings throughout Commerce. When we repair a CertainTeed roof, we use OEM shingles, underlayments, and accessories wherever warranty compliance matters. Where OEM isn’t required, we source quality aftermarket components that fit the existing roof correctly. This keeps repair costs down without cutting corners. For flat roof patch work in Commerce, we keep common Flintlastic materials in our inventory so we can move faster on commercial jobs.

FAQs – CertainTeed Roofing in Commerce
Commerce’s intense UV and smog load bake Flintlastic membranes, causing the modified bitumen surface to crack and seams to separate over time. Winter rain then finds those open seams and gets into the deck. The fix is usually a targeted repair, not a full replacement. Call (833) 467-4901 and we’ll assess the damage honestly.
Yes, in many cases. Ponding at clogged scuppers or drains often means clearing the drainage path, repairing the damaged membrane section, and sometimes replacing a rotted deck edge. We did exactly this on a 1960s Commerce warehouse recently and saved the owner from a full re-roof. Call (833) 467-4901 for an inspection and quote.
Yes. Landmark architectural shingles are a solid choice for Commerce’s tract homes, and we install them regularly. We’ll also tell you honestly if another shingle in our seven-brand portfolio would hold up better on your particular roof’s sun exposure. Repair or replace, we’ll tell you which one actually makes sense.
Don’t wait. Granule loss means the shingle’s protective layer is gone, and a leak means water is already getting through. We can replace individual shingles if the damage is localized, or a full slope if it’s widespread. Book a standalone roof inspection first, so you know exactly what you’re dealing with. Call (833) 467-4901.
No. We are an independent CertainTeed service provider, not a manufacturer-authorized contractor, and we also handle CertainTeed repair in Bell Gardens.

We use CertainTeed OEM materials when warranty compliance matters, but we’ll also tell you when a repair is the better financial move than a replacement. Call (833) 467-4901 for a straight answer.
