CertainTeed Roofing in Willowbrook, CA | Chatham Roof Repair
We install and repair CertainTeed roofing systems throughout Willowbrook, and we’re an independent contractor, not a manufacturer-authorized dealer. The thing that makes our CertainTeed work here different is simple: we know how these products behave on the flat and low-slope roofs that dominate this unincorporated pocket of South LA. From Landmark shingles on pitched sections to Flintlastic and Rubbergard membranes on 1940s-era flat roofs, we diagnose first and recommend the smallest fix that holds. Call (866) 361-1724 to schedule a free estimate.
Why Willowbrook Residents Choose Us for CertainTeed Service
Our crews read CertainTeed’s published installation requirements closely, because inland South LA heat and drainage failures punish shortcuts. Homeowners looking for West Athens CertainTeed service face the same challenges. We also carry the accessory components that matter: SwiftLock, Flintlastic SA, Xtreme WeatherGuard, and matching ridge and starter. That’s the difference between a patch that looks right and a patch that’s actually tied into the roof as a system.
Nelson Quarry, our owner, grew up in Morningside Park in Inglewood and has spent nearly three decades watching what the Southern California sun, Santa Ana winds, and the occasional El Niño winter do to a roof that was installed wrong the first time. He’s known locally for flat-roof diagnostics, the kind of slow hidden leaks that show up on a ceiling six feet from where the actual problem is. The same expertise applies to CertainTeed repair in Lynwood. He explains exactly what failed and why before any work starts. It’s how we earn trust in Willowbrook without leaning on slogans.
For homeowners deciding between repair and replacement, we offer CertainTeed sales & service across the full product range, and we’re honest about which option makes sense. A lot of the roofs in this community have years of life left in them if the flashing and drainage get corrected early.

Common CertainTeed Roofing Problems We Solve in Willowbrook
- Landmark shingle cracking and granule loss on west- and south-facing slopes. The inland heat here bakes those exposures year after year. The sealant strips on Landmark shingles melt and re-seal inconsistently during heat cycling, which loosens the shingle’s bond and accelerates granule shedding. We see it most on the stucco homes along the younger side streets off Central Avenue.
- Flintlastic and Rubbergard low-slope membrane seam failures at ponding points. Flat roofs in Willowbrook collect water anywhere drainage wasn’t corrected, and the first winter rain pushes water back under laps that looked fine in July. The entire 90059 area deals with this every season.
- Xtreme WeatherGuard underlayment wrinkling and telegraphing on original 1940s – 60s roof decks. Older decking with soft spots or uneven sheathing causes the underlayment to wrinkle, which then telegraphs through the shingles above as ridges. On a hot day, that ridging gets worse.
- Fastener and flashing failures at stucco wall and parapet terminations. Tight lots mean mature trees, and tree debris keeps valleys and scuppers clogged. Water backs up at the terminations, eats away at the flashing, and eventually gets into the wall. Flat-roof leak repair in Willowbrook almost always involves a clogged scupper somewhere.
- Isolated flat-roof patch failures that spread if ignored. A small split in a Flintlastic seam becomes a bigger split after a few heat cycles. We push honest patch-and-repair for these isolated failures on older homes, because full replacement often isn’t warranted yet.
CertainTeed Service in Willowbrook: What Local Conditions Mean for Your Equipment
Willowbrook is an unincorporated community wedged between Compton, Watts, and the 105 freeway, just north of South Gate CertainTeed service areas. That matters for your roof in a way it doesn’t in a city like Inglewood or Hawthorne: roof permits here go through LA County rather than a city building department. Every CertainTeed re-roof and flat-roof replacement we pull in the 90059 ZIP is scoped and inspected to County standards. That matters most on the low-slope drainage corrections this neighborhood needs, because the County looks hard at ponding and positive drainage on flat roofs. If your Flintlastic or Rubbergard roof is failing at the same drain or scupper every winter, the fix isn’t just another patch. It’s correcting the slope so water can’t sit there in the first place.
We worked on a 1950s stucco home near the 105 where the first hard rain of the season sent water through a Flintlastic low-slope section. A scupper had stayed clogged under tree debris all summer, and the membrane seam at the ponding point had failed. We cleared the drain, cut out and re-lapped the failed seam, reset the wall flashing where it met the stucco parapet, and patched rather than replaced the Landmark field shingles on the pitched section, which were still sound. The owner had a dry roof through the next storm for a fraction of a full tear-off. We bring the same repair-first approach to CertainTeed in Florence-Graham. That’s the kind of repair-first call we make all over Willowbrook.
CertainTeed Models & Products We Service in Willowbrook
We install and repair the full CertainTeed lineup that shows up on Willowbrook roofs: Landmark, Landmark 30, and Landmark Pro architectural shingles on pitched sections; Presidential and Presidential Shake luxury architectural shingles; and Flintlastic SA self-adhered and Rubbergard low-slope membrane systems on the flat and near-flat roofs that dominate this neighborhood. We also work with Xtreme WeatherGuard and SwiftLock underlayments.
Where the system warranty logic depends on genuine CertainTeed components, we use them: SwiftLock, Flintlastic SA, Xtreme WeatherGuard, and matching ridge and starter. For flashing and fasteners, we use quality aftermarket parts where they perform equal or better. We stock common CertainTeed accessories locally so most Willowbrook service calls don’t wait on a distributor order.

AfterCertainTeed Service Pricing in Willowbrook
CertainTeed service costs in Willowbrook usually fall into a few predictable buckets. A flat-roof patch with seam re-lap and drain clearing runs roughly $350 to $800. Flashing repair at stucco wall or parapet terminations typically lands between $450 and $1,200. A partial Landmark shingle patch on a pitched section is $500 to $1,500. A full flat-roof replacement with Flintlastic or Rubbergard on a typical Willowbrook low-slope roof runs $8,000 to $18,000, and a full CertainTeed shingle re-roof runs $12,000 to $30,000. What moves the number is decking condition, access, drainage correction, and how much of the old membrane has to come off.

FAQs – CertainTeed Roofing in Willowbrook
Yes, in most cases we can repair a Flintlastic flat roof without a full replacement. If the membrane is failing at a specific seam, scupper, or ponding point and the surrounding material still has integrity, we cut out the failed section, re-lap new Flintlastic SA, and correct the drainage so water can’t sit there again. Full replacement only makes sense when the membrane is brittle across large areas or the decking underneath is soft. Call (866) 361-1724 and we’ll tell you which one you’re looking at.
The inland South LA heat is the culprit. West- and south-facing slopes in Willowbrook take direct sun for the hottest part of the day, and the thermal cycling from hot afternoons to cool nights causes the shingle mat to expand and contract. The sealant strips melt and re-seal inconsistently, which weakens the bond and lets granules shed. A roof that’s twenty years old in a cooler climate can look fifteen years older here.
Yes. Because Willowbrook is unincorporated, roof permits go through LA County rather than a city building department. That changes the inspection standards, especially on flat and low-slope roofs where the County looks carefully at drainage and positive slope. Every CertainTeed re-roof we pull in the 90059 area is scoped and inspected to those County standards.
Yes, we match Landmark shingles by profile, color, and warranty class when patching a section. Multi-brand inventory means we’re not trying to force a different manufacturer’s shingle onto a CertainTeed roof. Matching the existing shingle keeps the repair from being visually obvious and avoids creating a manufacturer coverage gap on the surrounding field.
Clogged drains and scuppers are almost always the trigger. The dry summer months drop debris from mature trees into the valleys and drains, and when the first hard rain arrives, water has nowhere to go. It ponds at the seams and terminations, and the pressure pushes it back under laps that were sealed all summer. The drainage correction matters as much as the membrane repair. Call (866) 361-1724 for an exact quote before the next storm.
