CertainTeed Roofing in Florence-Graham, CA | Orange County Roofing Co
We provide independent CertainTeed roofing service across Florence-Graham’s 90001 zip code, from Landmark shingle fields to Flintlastic low-slope sections over garage conversions. The thing that sets our CertainTeed work apart here: we understand unincorporated LA County permitting and we understand party-wall drainage on tight lots, because that’s what Florence-Graham roofs actually deal with. We are not authorized, sponsored, or warranty-endorsed by CertainTeed. We’re a local crew that carries seven major brands so the recommendation you get is the one your roof needs. Call (866) 942-4187 to schedule a free estimate.
Why Florence-Graham Residents Choose Us for CertainTeed Service
Most roofing companies in South LA either sell one brand or sell whatever they can get cheapest that week. We stock CertainTeed sales & service materials alongside GAF, Owens Corning, IKO, Atlas, Tamko, and Boral, so when we tell you a CertainTeed Landmark is the right shingle for your bungalow, it’s because the roof said so, not because our supplier ran a promo. That’s the way Kurt Hensley has run this company from the start. He grew up in the Serrano Heights area of Orange watching crews work tile roofs on hillside homes, and the lesson stuck: the right material, installed clean, beats a brand pitch every time. For Florence-Graham homeowners, that means we’ll match CertainTeed-spec underlayment and flashing to your existing assembly rather than forcing a brand swap mid-roof. If you’ve got a failing rolled roof over a converted garage, we’ll talk straight about whether a patch buys you years or just buys you another leak. No pressure. Just an honest read on what you’re standing under.

Common CertainTeed Roofing Problems We Solve in Florence-Graham
- Curled and granule-bald shingles on south and west slopes. Florence-Graham’s sun is unrelenting. On pre-1960 stucco bungalows, the south-facing CertainTeed three-tab or early architectural shingles bake years ahead of the north slope. We see tabs that never sealed, granules in the gutters, and shingles brittle enough that a Santa Ana gust lifts them clean off. The fix is usually a slope-specific replacement, not a full roof, unless the deck underneath tells a different story.
- Ponding water at the shared property-line parapet. Flat CertainTeed sections over rear units and garage conversions drain toward the lot line, where water sits against the party-wall flashing and wicks into the neighbor’s stucco. This is the most common call we get in Florence-Graham. It’s a drainage failure, not a product failure, and it needs flashing rebuilt with an actual drainage path, not another coat of mastic.
- Leaks after rare but heavy winter rain. When a real storm hits, every low spot on a flat CertainTeed roof announces itself. Dried-out flashing at parapets and plumbing penetrations backs water up under the field instead of shedding it. We trace the low spots with a hose and fix the flashing, not just the visible leak.
- Fastener back-out and ridge cracking over skip sheathing. Original CertainTeed 3-tab fields on 1920s – 1950s wood-frame homes were often laid over skip sheathing. The deck boards move with heat and age, and the fasteners walk out with them. You’ll see cracked ridge caps and tabs that look stapled on. Repair only makes sense when the deck is still sound. If it’s not, we’ll tell you.
- Flintlastic SA low-slope failures at parapet transitions. CertainTeed’s self-adhered modified bitumen is a good system for low-slope work, but on Florence-Graham’s narrow lots the transition where the flat section ties into the stucco parapet is where water gets in. We strip and re-flash those transitions properly, then tie the new CertainTeed assembly back into the existing stucco cleanly.
CertainTeed Service in Florence-Graham: What Local Conditions Mean for Your Equipment
Florence-Graham is unincorporated LA County, and that one fact reorganizes every CertainTeed re-roof here. Permits and inspections run through LA County Public Works/Building & Safety, not a city counter. That changes how we phase a tear-off: the county inspector has to see the deck after the old material comes off and before new underlayment goes down. If your tear-off schedule misses that inspection window, you’re looking at delays, and on a 5,000-square-foot lot with a rear unit and a converted garage, a stalled roof is a roof that gets rained on at the worst possible time. We schedule county inspections into the job from day one, not as an afterthought. It also means the county’s minimum deck and fastening standards apply, not whatever the last contractor decided was fine. For a 1940s bungalow with skip sheathing and original CertainTeed 3-tab, that often means re-decking sections before new material goes down. We’d rather tell you that upfront than discover it mid-job and hand you a change order. Florence-Graham service area work is what we do, and we know how the county wants it done.
CertainTeed Models & Products We Service in Florence-Graham
We work on the full CertainTeed residential lineup you’re likely to find on Florence-Graham roofs, and we also offer Roof Repair – Florence-Graham for all these systems. Landmark architectural shingles, the most common CertainTeed field we see on pitched bungalow roofs. XT 25 and XT 30 three-tab shingles, still hanging on from roofs put down in the 1990s and early 2000s. Flintlastic SA self-adhered modified bitumen for low-slope sections over garages and rear additions. RoofRunner and other CertainTeed underlayment systems. When a repair needs OEM-spec materials, we carry certainteed-matching shingles, underlayment, and flashing in our local supply rotation so we’re not waiting on a distributor in another county to ship before we can start. That keeps turnaround tight for Florence-Graham customers, even on flat-roof patches that need to happen before the next rain.

AfterCertainTeed Service Pricing in Florence-Graham
What you’ll pay depends on what we find. A targeted patch on a flat CertainTeed section, re-flashing a parapet, or replacing a handful of granule-bald shingles on a sun-baked slope sits on the lower end. A full tear-off and re-roof with new CertainTeed material, re-decking over skip sheathing, and county inspections runs significantly more. Here’s a rough sense of how costs break down locally:
- Shingle patch or small repair: $350 – $900, depending on access and how much flashing needs rebuilding.
- Flat-roof patch with parapet re-flashing: $800 – $2,200, with the party-wall condition as the biggest variable.
- Full bungalow re-roof with CertainTeed Landmark: $9,000 – $16,000, before any re-decking that county inspection requires.
- Flintlastic SA low-slope section replacement: $2,800 – $6,500 based on square footage and parapet detail.
Every estimate is free, written out line by line, and the price we quote is the price you sign for. No swap-outs on materials. Call (866) 942-4187 for an exact quote on your CertainTeed roof.

FAQs – CertainTeed Roofing in Florence-Graham
Because the drainage path terminates at the shared property-line parapet, and that flashing was almost certainly never rebuilt to actually move water away from the wall. On tight Florence-Graham lots, water ponds against the party wall, sits there, and wicks under the flashing into the neighbor’s stucco. Patching the low spot buys a few months. Rebuilding the party-wall flashing with a proper drainage path fixes it for years. Call (866) 942-4187 and we’ll trace the water and show you exactly what’s happening.
Yes. Florence-Graham is unincorporated LA County, so every re-roof is permitted and inspected through LA County Public Works/Building & Safety, not a city counter. The inspector has to see the deck after tear-off and before new material goes down. We handle the permit, schedule the inspection into the job phase, and make sure the county signs off before the final shingle goes on.
Usually not. On Florence-Graham bungalows, the south and west slopes take years of UV abuse that the north slope never sees, so it’s common to replace one slope while the other has real life left — the same pattern we see when providing South Gate CertainTeed service. We’ll get on the roof, check the deck and flashing, and tell you whether a slope-specific replacement makes sense or whether the rest of the roof is close enough to end-of-life that a full replacement is the cheaper long-run call.
You can’t shingle over a flat or very low-slope roof, and trying it creates a bigger problem than the one you have. Shingles need slope to shed water. On the flat sections over Florence-Graham rear units and garage conversions, the right answer is a modified bitumen system like CertainTeed Flintlastic SA, tied properly into the parapets and party walls — an approach we also use for CertainTeed repair in Walnut Park. We’ll tell you if the existing rolled roof has to come off or if it can be overlaid, based on what the deck and county inspector say.
For flat and low-slope work on Florence-Graham garages, rear units, and additions, we install CertainTeed Flintlastic SA self-adhered modified bitumen, with CertainTeed-spec flashing and underlayment to match. On pitched bungalow roofs, we install CertainTeed Landmark architectural shingles. We’re an independent CertainTeed service provider, not authorized or warranty-endorsed by CertainTeed, so we pair the right CertainTeed product with the right deck and drainage conditions, not the other way around.
