We provide independent CertainTeed roofing service across Florence-Graham (ZIP 90001), from Roof Repair – Florence-Graham to full replacement.

We’re Chatham Roof Repair, and we’ve torn into enough CertainTeed installs on Florence-Graham’s post-war stucco bungalows to know how Landmark shingles age under inland South LA sun rather than coastal fog. We’re an independent roofer, not authorized, sponsored, or warranty-endorsed by CertainTeed. That independence means we call it straight: some CertainTeed roofs here are worth repairing. Some aren’t. We’ll show you which one you have.

Why Florence-Graham Residents Choose Us for CertainTeed Service

Most roofing companies in this part of Los Angeles County will either push a full replacement on sight or slap a mismatched patch over a problem and call it done, unlike our Huntington Park CertainTeed service approach. Neither approach fits Florence-Graham’s housing stock, which is mostly 1920s to 1960s wood-frame stucco bungalows and small cottages on narrow lots, many converted into multi-unit rentals. Those roofs carry original or overlaid composition shingles, minimal attic ventilation, and plenty of flat-roof additions and patched garage tie-ins. We’ve worked all of it.

Nelson Quarry, our owner, grew up in Morningside Park 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 wasn’t installed right the first time. He picked up the trade at Los Angeles Trade-Technical College and spent years doing field work across the South Bay before settling back in Inglewood, where his family still lives. 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. That diagnostic mindset is baked into how we handle every CertainTeed roof in Florence-Graham. We look for the repair before we recommend the replacement. Then we explain what failed and why before we ever pick up a tool.

Common CertainTeed Roofing Problems We Solve in Florence-Graham

• Granule loss and sun-brittling on Landmark slopes. The inland UV in 90001 bakes dark asphalt far harder than the coast does. South- and west-facing CertainTeed Landmark shingles here go chalky and thin years before the nominal warranty life. We inspect for granule wash-off in gutters and test for brittleness at the tab edges, then tell you honestly whether the field still has service life left.
• Valleys packed with jacaranda and ficus litter. This is the defining failure mode in Florence-Graham. Leaf debris traps moisture against CertainTeed shingle tabs and rots the valley before the field shingles show any wear at all. A roof can look fine from the street and be soft as cardboard at the valley.
• Failed sealant strips and lifted tabs on older XtraPly three-tab courses. Hot dry cycles loosen the adhesive bond, then the rare winter storm drives water under lapped courses. We see this most often on original and overlaid three-tab roofs from the 1950s and 1960s.
• Overlaid second-layer CertainTeed shingles hiding soft decking. Many Florence-Graham bungalows have a second layer over the original, with minimal attic ventilation. Trapped heat cooks both layers and softens the decking underneath. By the time water shows on a ceiling, the damage is already done.
• Flat-roof and low-slope tie-in leaks on converted garages and porches. These additions were flashed into the main shingle roof decades ago, often with materials that have long since failed. We trace the leak back to the actual source, which is rarely where the ceiling stain says it is.

CertainTeed Service in Florence-Graham: What Local Conditions Mean for Your Roof

Florence-Graham is an unincorporated Los Angeles County pocket, ZIP 90001, dominated by densely packed post-war stucco bungalows and small multi-unit rentals. Roofing work here is shaped less by severe weather than by landlords and families stretching aging roofs past their service life in a dense, tree-canopied neighborhood. That’s the key difference from coastal LA, and it shows up in a very specific way on CertainTeed roofs: the long, dry, hot season bakes the shingle field year after year, while the jacaranda and ficus canopy drops leaf litter that packs valleys and gutters and holds moisture against the tabs. The result is predictable. On most CertainTeed roofs in Florence-Graham, the valleys and gutter edges fail from trapped moisture and rot before the shingle field itself wears out. A roofer who only looks at the field shingles misses the actual problem. We start our inspections at the valleys, the gutter lines, and the flat-roof tie-ins, because that’s where Florence-Graham roofs actually die.

On a narrow-lot bungalow off a canopy-lined street in 90001, our crew found a CertainTeed Landmark roof whose shingles still looked decent from the ladder. The valley was packed solid with jacaranda litter and had rotted through to soft decking. We stripped the valley, replaced the rotted decking, re-laid new CertainTeed shingles into the slope, and cleared the gutters. The owner’s ceiling stain stopped without touching the rest of a still-serviceable field. That’s the repair-first approach: fix what’s failed, leave what’s sound, and don’t sell a roof the customer doesn’t need.

CertainTeed Models & Products We Service in Florence-Graham

We work on the full range of CertainTeed roofing you’re likely to find in Florence-Graham: Landmark architectural shingles, the high-end Xtreme WeatherGuard line (formerly Presidential Solaris), older XtraPly three-tab composition shingles on original and overlaid bungalow roofs, and CertainTeed flat-roof and low-slope membrane products on converted garage and porch tie-ins. Our CertainTeed sales & service work covers inspection, repair, and replacement across all of it.

For patch work, we match CertainTeed colors and profiles using genuine CertainTeed shingles where a patch has to blend. For underlayment, flashing, and vent boots, we use quality aftermarket materials where they outperform the original detail. That’s the honest approach: OEM where appearance and coverage matter, better materials where the factory spec was marginal to begin with. It means faster turnaround for Florence-Graham customers and those needing CertainTeed repair in Walnut Park because we’re not waiting on a single-brand supply chain for every component.
