CertainTeed Roofing in Commerce, CA | True North Roof Repair
We provide independent CertainTeed roofing service across Commerce, CA, covering everything from Landmark shingle repairs on mid-century homes to Flintlastic SA membrane patches on the city’s flat-roofed warehouses. What makes our CertainTeed work here different is simple: we know this city’s two-market roofscape, and we match the repair to the actual roof, not to a sales quota. Call (866) 617-1004 for a free estimate on any CertainTeed roof in Commerce.
Why Commerce Residents Choose Us for CertainTeed Service
Most roofing crews in southeast LA County either chase residential shingle work or focus on commercial flat roofs. Here in Commerce, you can’t split it that cleanly. The same street off the rail corridor might hold a 1950s stucco house with Landmark architectural shingles next to a concrete-tilt-up warehouse with a built-up roof. We’ve worked CertainTeed sales & service long enough to know both worlds, and that’s the real reason Commerce homeowners and building owners call us.
We’re an independent CertainTeed service provider, which means we’re not locked into pushing a single product line. Noel Ibarra, our owner, grew up in Norwalk and learned roofing systems through the construction technology program at Cerritos College before spending two decades on roofs across the San Gabriel Valley and southeast LA County. He built True North around one idea: diagnose first, spend second. That matters when you’re deciding between a $400 patch and a $14,000 replacement. We lay out the options. You choose the path.

Common CertainTeed Roofing Problems We Solve in Commerce
- Sun-baked granule loss on Landmark and XT shingles. Commerce sits in the hot, dry inland LA basin, and south- and west-facing slopes take brutal UV exposure year after year. We regularly see CertainTeed architectural shingles losing their weathering layer years earlier than manufacturers expect in milder climates. The granules collect in gutters and at downspout elbows. That’s not just cosmetic, it’s the mat underneath starting to cook.
- Wind-scoured and lifted shingle edges after Santa Ana events. When Santa Ana winds rake through Commerce, the exposed roof planes on low-slung mid-century homes catch the worst of it. We find ridge caps and field shingles lifted along the windward edges, with the nail line exposed. Hand-sealing and replacing those before winter rain matters more than most homeowners realize.
- Flintlastic SA membrane seam failures on flat and low-pitch roofs. Commerce has an unusually high concentration of flat-roofed warehouses, trucking terminals, and older homes with low-slope sections. Flintlastic SA is a workhorse membrane, but ponding at scuppers after even modest rain keeps water sitting on the seams, and the coating breaks down under inland sun. We patch seams and re-coat rather than pushing full tear-off when the field is still sound.
- Cracked sealant at penetrations and vent boots after dry heat cycling. Years of Commerce heat expansions and contractions crack the sealant around pipes, vents, and chimneys long before the shingles themselves fail. Wind-driven rain then tracks under the shingle courses. We replace vent boots with quality aftermarket components where OEM adds no real service life, and re-flash penetrations properly.
- Nail-line and fastener corrosion on older CertainTeed systems. The dry climate doesn’t stop the slow corrosion that happens where fasteners meet moisture trapped under shingle courses. We see this on 20-plus-year-old CertainTeed roofs across Commerce, especially near the ridge where thermal cycling is most aggressive. It’s one of the first things we check during a roof inspection.
CertainTeed Service in Commerce: What Local Conditions Mean for Your Equipment
Commerce is one of the few southeast LA County cities where the same street mixes mid-century residential roofs with flat-roofed warehouses and trucking terminals. That’s not true in Downey, Bell, or Cerritos. Here, a CertainTeed crew routinely handles a low-slope Flintlastic patch and a shingle wind-lift repair on the same block, sometimes the same building. On the residential blocks near the rail corridor, we find Landmark architectural shingles scoured and lifting along west-facing slopes after Santa Ana wind events, granule loss exposing the mat near the ridge. Walk two blocks east and we’re on a flat roof where the failure is ponding water eating the membrane seams around scuppers. Knowing which failure mode you’re dealing with before touching the roof is the whole game. That’s why every job starts with an inspection, not a proposal.
CertainTeed Models & Products We Service in Commerce
We service the full range of CertainTeed residential and low-slope products you’ll find across Commerce: Landmark architectural shingles, Presidential Shake luxury shingles, XT 25 and XT 30 three-tab shingles, and Flintlastic SA self-adhered membrane. When a repair calls for matching material, we use CertainTeed OEM shingles, ridge caps, and Flintlastic membrane where the product is still in production. For underlayment, flashing, and vent boots, we often recommend quality aftermarket components that perform as well or better without the OEM markup. We keep common CertainTeed colors and accessories stocked for fast Commerce turnaround because nobody wants to wait three weeks for a ridge cap match.

CertainTeed roof repair in Commerce typically runs $350 to $900 for targeted leak and flashing repairs, while full replacement of a Landmark shingle roof on an average Commerce home falls between $12,000 and $18,000 depending on square footage, pitch, and decking condition. Flintlastic SA membrane patches on flat sections usually land between $800 and $2,500. What drives the cost is access, the extent of sun or wind damage, and whether the decking is still sound.

FAQs – CertainTeed Roofing in Commerce
Commerce’s inland-basin sun is intense, and south- and west-facing slopes get years of UV exposure compressed into a shorter window than shingles in coastal or cooler climates would see. The granule loss you’re seeing is the weathering layer being stripped away, which exposes the asphalt mat underneath to further damage. The fix depends on how far it’s gone. If the field is mostly sound, we can hand-seal and replace the worst sections. If granule loss is widespread and the mat is exposed in multiple areas, a full replacement is often the only honest answer. Call (866) 617-1004 and tell me what you’re seeing and we’ll figure out what’s actually going on.
In most cases, yes. Flintlastic SA is designed to be repairable, and we patch seams, scupper areas, and isolated membrane damage regularly across Commerce’s flat-roofed industrial buildings. The catch is the condition of the existing membrane. If the coating has broken down across large areas or the membrane is brittle and cracking everywhere, patching just moves the leak to the next seam. We’ll inspect and tell you straight which situation you have. Call (866) 617-1004 for a free flat roof assessment.
In Commerce, it’s usually both. Santa Ana wind events lift shingle edges and ridge caps, then the winter rain that follows drives water under those lifted courses and into the house. We trace the leak path to determine whether the primary cause was wind damage, failed sealant at penetrations, or membrane breakdown on a low-slope section. The repair approach changes depending on the answer. That diagnostic is the first thing we do on any leak call. Call (866) 617-1004 and we’ll start there.
Yes. Commerce’s mixed roofscape means many homes and buildings here have a shingle roof on the main structure and a flat or low-slope section over an addition, carport, or commercial bay, similar to what we see with CertainTeed repair in Bell Gardens. We handle both under one crew, which saves you from coordinating two contractors. The same team that patches Flintlastic SA membrane on a flat section can repair wind-scoured Landmark shingles on the gable roof in the same visit. Call (866) 617-1004 to schedule an inspection of the whole roof system.
CertainTeed’s warranty covers manufacturing defects, not storm or sun damage, so a repair done correctly with matching materials shouldn’t void your coverage. What can void it is improper installation or using incompatible materials. That’s why we match CertainTeed OEM shingles and ridge accessories where the product is still in production, and why our documentation is thorough. If you’re concerned about warranty implications, we’ll walk you through exactly what we’re doing and why before the work starts. Call (866) 617-1004 with your questions.
