CertainTeed Roofing in Florence-Graham, CA | Sunridge Roof Repair
We service and repair CertainTeed roofs throughout Florence-Graham, ZIP 90001, as an independent roofing contractor offering our CertainTeed services. What makes our CertainTeed work different here comes down to the housing stock: patch-and-repair on dense lots, tie-ins to non-permitted additions, and County of LA inspections instead of City of LA. If your CertainTeed roof is leaking or showing its age, call Sunridge Roof Repair at (833) 589-5180 for an honest read on whether it needs a repair or a replacement.
Why Florence-Graham Residents Choose Us for CertainTeed Service
CertainTeed roofs are common across Florence-Graham, particularly Landmark architectural shingles on the post-war stucco bungalows and XT three-tab shingles on older starter homes. Our crews work on these systems every week, which means we can spot a failing Landmark before it becomes a ceiling stain and we know which XT failures are worth patching versus which ones signal the roof is done. We inspect before we recommend, period. Ruben Ochoa, who owns Sunridge, started in this trade because he grew up watching relatives patch roofs in nearby Lynwood and wanted to do the work properly. That background shows up in how we handle every Florence-Graham job: a straight answer about what your roof actually needs, not a sales pitch for a replacement you could put off for five more years.
We’re independent, not manufacturer-affiliated. That matters because our recommendation is driven by your roof’s condition and your budget, not by a quota from a brand rep. If CertainTeed is the right fit for your Florence-Graham roof, we’ll say so and we’ll use CertainTeed-compatible materials. If a patch with quality aftermarket flashing makes more sense than OEM parts, we’ll tell you that too. Your choice of materials, always.

Common CertainTeed Roofing Problems We Solve in Florence-Graham
- Landmark granule loss on south- and west-facing slopes. Florence-Graham’s intense summer UV beats down on these slopes year after year. We regularly see Landmark shingles showing severe granule loss and surface cracking after 12 to 15 years, well before the rated life. The granules end up in gutters and the shingle core gets brittle, which means the next heavy winter rain finds a way in.
- XT 25 tab curling and nail-head pops over unvented attics. The 1920s-through-1950s bungalows in Florence-Graham rarely have proper attic ventilation. Heat builds up under the deck, the XT 25 tabs curl, and nail heads pop through. The failure often starts above the back addition or converted garage, where airflow is worst.
- Flintlastic flat-roof seam splits on additions. Converted garages and backyard additions in Florence-Graham frequently have Flintlastic low-slope membranes. Southland thermal expansion and contraction works the seams open little by little. Summer heat creates the cracks; winter rain exploits them. The leak you see in December usually started forming in August.
- Dry-rot at tie-ins where CertainTeed shingles meet a neighbor’s wall or a flat-roof transition. On Florence-Graham’s tight lots, additions often tie directly into a shared wall or a stucco parapet. Shingles get cut tight without proper kick-out flashing, water wicks behind the stucco, and the framing rots. This is a CertainTeed-specific repair we do routinely.
- Failed step flashing at shingle-to-addition transitions. A large share of our Florence-Graham leak calls trace back to step flashing where the original house roof meets an addition. The addition might be permitted or not, but the flashing detail is almost always undersized or poorly lapped. We rebuild the kick-out and re-lay matching shingles.
CertainTeed Service in Florence-Graham: What Local Conditions Mean for Your Roof
Here’s the detail most contractors miss about Florence-Graham: this is unincorporated LA County, not the City of LA. Every CertainTeed re-roof, and even a large patch, has to be permitted and inspected through LA County Building & Safety. That’s a different department, different paperwork, and a different inspection sequence than what City of LA contractors are used to. We walked a homeowner near the 90001 core through this exact process earlier this year on a 1940s stucco bungalow where a Landmark roof tied into a converted-garage addition that had never been permitted with the County. We pulled the decayed flashing, rebuilt the kick-out, re-laid Landmark shingles to match the field, and then walked them through the County inspection paperwork so the repair was on record. If a contractor tells you a big CertainTeed patch in Florence-Graham doesn’t need a permit, they’re guessing. County rules apply here and they change how the whole job gets documented.
That unincorporated status also shapes the roofing culture in Florence-Graham. Dense lots, small homes, and additions passed down through families mean most roofs here are repaired, patched, and tied into rather than torn off and replaced. CertainTeed’s low-slope and architectural shingle lines fit that reality well, but they have to be installed and flashed correctly at those tie-ins. We’ve fixed enough of these to know exactly where they fail.
CertainTeed Models & Products We Service in Florence-Graham
We service every major CertainTeed roofing system you’re likely to find in Florence-Graham: Landmark architectural shingles, XT 25 and XT 30 three-tab shingles, Flintlastic low-slope modified bitumen membranes, and Solaris or Presidential shake-style shingles on the scattered upgraded homes. When an OEM match matters for appearance or performance, we use CertainTeed shingles, underlayments, and flashing components. When a quality aftermarket boot or sealant outperforms the original at a lower cost, we’ll recommend that instead and explain why. We keep common CertainTeed colors and accessory stock on hand for fast turnaround in ZIP 90001, so a straightforward patch doesn’t wait on a supplier order. For matching harder-to-find colors, we’ll order exact and tell you the lead time up front.

AfterCertainTeed Service Pricing in Florence-Graham
CertainTeed roofing work in Florence-Graham varies more by scope than by brand. A small flashing repair or flat-roof patch typically runs a few hundred dollars; a full Landmark re-roof on a small post-war bungalow is a multi-thousand-dollar job because it includes tear-off, dry-rot repair if present, underlayment, shingles, and County permit and inspection fees. On a 20-year-old CertainTeed roof with isolated damage, we’ll patch and re-flash rather than push a replacement. When granule loss or deck rot runs wall to wall, we’ll tell you straight that a full tear-off is the only honest fix. Every quote is free, written, and line-itemed so you can see what you’re paying for. Call (833) 589-5180 to schedule your free estimate in Florence-Graham or for South Gate CertainTeed service.

FAQs – CertainTeed Roofing in Florence-Graham
It depends on how widespread the granule loss and cracking are. If the damage is confined to one or two slopes, a patch with matching Landmark shingles and new flashing will usually buy you several more years. If granule loss runs across most of the roof and the shingles are brittle, a full replacement is the only honest fix. We’ll inspect and show you photos of what we’re seeing, then let you decide. Call (833) 589-5180 for a straight assessment.
An LA County permit is what applies in Florence-Graham. This is unincorporated County territory, so LA County Building & Safety governs permits and inspections, not the City of LA. A small leak repair or flashing patch usually doesn’t need a permit, but a large re-roof or structural repair does. We handle the paperwork and coordinate the inspection.
Nearly always, it’s heat buildup from an unvented attic or a poorly framed tie-in where the addition meets the main house. XT 25 three-tab shingles curl and pop nail heads when the deck overheats, and the back addition is usually the hottest, least-ventilated part of the roof. We’ll trace the failure to its source and tell you whether the fix is ventilation, flashing, or new shingles.
We match the color and profile as closely as the CertainTeed product line allows. A new Landmark bundle will not look identical to shingles that have weathered for 15 years, but we can get it close. On a highly visible slope, we’ll often harvest shingles from a less visible area and lay the new bundle there, so the patch blends better where it matters.
The seams on a Flintlastic membrane open up from thermal movement, and patching over them with a tube of sealant never lasts in Florence-Graham’s sun. The proper fix is to clean and re-adhere or torch the seam, then reinforce it with a compatible modified bitumen patch. We do these flat-roof patches routinely on the converted garages and additions common in ZIP 90001. Call (833) 589-5180 for an exact quote, estimates are free.
