CertainTeed Roofing in Commerce, CA | Sunridge Roof Repair
Sunridge Roof Repair provides independent CertainTeed roofing service across Commerce, from compact residential streets to the flat-roof warehouses near the 5/710 interchange. What makes our CertainTeed work different here is that we understand how Landmark shingles and Flintlastic low-slope systems actually fail in Commerce’s intense inland heat and on its aging mid-century housing stock. We inspect first, then recommend the right fix. Call (833) 589-5180 for a free CertainTeed roof assessment in Commerce.
Why Commerce Residents Choose Us for CertainTeed Service
Ruben Ochoa, our owner, spent over a decade fixing roofs across Southeast LA before starting Sunridge, and he’ll be the first to tell you that CertainTeed roofs in Commerce don’t fail the way they do in Downey or Bell Gardens. The heat loading here, combined with the age of the housing stock, creates a specific set of problems. We’ve torn off and replaced hundreds of CertainTeed roofs across Commerce’s mix of mid-century stucco homes and flat industrial buildings, so we know how Landmark shingles and Flintlastic systems actually behave after years of inland UV exposure. Our crew reads CertainTeed’s installation instructions line by line and never claims manufacturer authorization. We’re an independent contractor that specializes in the brand, which means our recommendations are driven by what your roof needs, not by a supplier agreement. That’s a difference you’ll hear in every conversation we have about your roof. We also offer full CertainTeed sales & service across the region.

Common CertainTeed Roofing Problems We Solve in Commerce
- Heat-cycled seal strip failure on Landmark shingles. West-side 1950s-60s stucco homes in Commerce take direct afternoon sun with no coastal breeze to cool things down. After 15-plus years, the seal strips on Landmark architectural shingles lose their grip, and tabs lift in the first decent Santa Ana wind. We see this on nearly every older CertainTeed roof we inspect in Commerce.
- Wind-lifted tabs on aging shingles. When the seal strips go, the tabs become sails. Commerce sits in a wind corridor between the 5 and 710 freeways, and any storm system that pushes through finds those loose tabs quickly. Replacing a few shingles without addressing the underlying seal failure is a temporary patch at best.
- Flintlastic SA granule loss at scuppers and drains. On flat warehouse roofs near the rail spurs, summer heat cycling opens seams at scupper locations. The Flintlastic granules wear away first, exposing the asphalt, and seam delamination follows. Ponding water at clogged drains accelerates everything.
- Cracked flashing and underlayment at low-slope porch and garage tie-ins. The older stucco homes west of the industrial core have low-slope porches and detached garages where thermal movement cracks CertainTeed underlayment and flashing details. When winter storms roll through Commerce, those hairline cracks admit water straight into the garage or living space.
- Brittle organic-mat shingles on original roofs. Homes with original CertainTeed organic-mat shingles from before 1990 are common in Commerce. Those shingles become brittle in the heat, lose granules rapidly, and even light foot traffic during an inspection can create leaks. We tell homeowners straight: a targeted repair may buy a season, but full replacement is the only long-term fix.
CertainTeed Service in Commerce: What Local Conditions Mean for Your Equipment
Commerce isn’t one roofscape, it’s two. Around the industrial core and rail spurs near the 5/710 interchange, summer heat cycling opens flat-roof seams at scuppers on rail-served warehouses and trucking facilities. That’s a Flintlastic SA problem. The membrane expands and contracts daily, the granules grind away at drain locations, and ponding water sits against the exposed asphalt until a seam lets go. Meanwhile, the compact streets west of the industrial core tell a different story entirely. Those post-war stucco tract houses, many still carrying original or second-covering CertainTeed organic-mat shingles, fail from the top down. The shingles crumble underfoot, and the low-slope porch and garage tie-ins crack at the flashing from thermal movement. Two completely different failure patterns on one city’s roofscape. That dual character is what distinguishes Commerce roofing from neighboring Downey or Bell Gardens, and it’s why we approach CertainTeed service here with both residential and flat-roof crews who know which pattern they’re looking at. If you’re anywhere in the Commerce service area, we’ll send the right eyes for your roof type.
CertainTeed Models & Products We Service in Commerce
We work on the full CertainTeed residential and low-slope lineup in Commerce: Landmark architectural shingles, Landmark Pro, Presidential Shake luxury shingles, and Flintlastic SA self-adhered membrane for flat and low-slope applications. When it comes to parts, our approach is simple. We use genuine CertainTeed accessories such as shingle starters, hip and ridge components, and Flintlastic membrane where they affect warranty or performance. Where quality aftermarket underlayments and fasteners do the same job for less, we use them and tell you why. For flat roof patches, shingle replacement, and flashing repair in Commerce, that mix of OEM and aftermarket gets you a better result at a fairer number. We keep common CertainTeed accessories stocked locally so turnaround on residential repairs doesn’t stall waiting on a shipment.

FAQs – CertainTeed Roofing in Commerce
Does CertainTeed make a flat-roof product suitable for my Commerce warehouse?
Yes. Flintlastic SA is CertainTeed’s self-adhered low-slope membrane, and it’s the product we most often install and repair on flat warehouse roofs in Commerce. The key is proper seam work at scuppers and drains, because that’s where Commerce’s summer heat cycling opens failures first. Call (833) 589-5180 and we’ll assess your roof’s specific condition.
My 1960s Commerce home has original CertainTeed shingles – can they be repaired or do I need a full replacement?
If they’re original organic-mat shingles from the 1960s, they’re past their useful life. Brittle, granule-shedding shingles can’t be reliably repaired, and every repair attempt risks more damage from foot traffic. We’ll confirm with an inspection and give you an honest answer either way. Call (833) 589-5180 for that inspection.
Why do CertainTeed roofs near the 5/710 interchange fail at scuppers so often?
The rail-served warehouses near the 5/710 see intense daily heat cycling on their flat roofs. Flintlastic membrane expands and contracts, granules wear away at the scupper openings, and ponding water sits against the exposed asphalt. Seam delamination follows. It’s a recurring pattern we see on nearly every flat industrial roof we inspect in that part of Commerce. If your roof is showing scupper-area wear, call (833) 589-5180 before the next storm.
How can I tell if my CertainTeed architectural shingles are still under warranty?
Check your closing documents for the original warranty registration, or contact CertainTeed directly with your address and installation date if known. As an independent contractor, we can assess the roof’s physical condition, but warranty determination rests with CertainTeed. We’ll help you understand what you’re looking at. Call (833) 589-5180 for an inspection.
Do you install CertainTeed metal roofing or only shingles?
We focus on CertainTeed asphalt shingle and low-slope membrane products: Landmark, Landmark Pro, Presidential Shake, and Flintlastic SA. We don’t install metal roofing under the CertainTeed name, but if your Commerce home or building needs metal, we’ll tell you and point you to a specialist who does it properly.
