Why Florence-Graham Residents Choose Us for CertainTeed Service

Ruben Acosta grew up in Belvedere, patching flat roofs with his uncle on the stucco homes near Belvedere Park. That’s where he learned what failing membrane actually looks like, long before he ever picked up a CertainTeed product. Now he brings that same read-the-roof-first approach to every Florence-Graham job. We’re not a CertainTeed-authorized dealer and we don’t pretend to be. What we are is a crew that has installed and repaired their Landmark, XT 25, and Flintlastic lines across South LA for years, so we know how these materials hold up under direct sun and annual winter rain cycles. Seven brands, one contractor. We carry GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, which means the recommendation we give you is based on what your Florence-Graham roof actually needs, not what we’re locked into selling. We inspect first, recommend second. That’s not a slogan; that’s the only way we’ve ever worked. For more on how we approach the brand, see our CertainTeed sales & service page.

Common CertainTeed Roofing Problems We Solve in Florence-Graham

• Landmark granule loss and edge curl on shallow-pitch front roofs. Florence-Graham’s pre-1960 bungalows often have front slopes pitched just enough to shed water but shallow enough that sun hits the shingle face at a brutal angle for decades. We see Landmark shingles lose granules and curl at the eaves, especially where attic ventilation is poor. The fix is usually targeted shingle replacement and improved venting, not a full tear-off.
• XT 25 three-tab cracking at tab edges on original wood sheathing. The 1920s-1950s homes around here sit on original 1x sheathing that has swelled and shifted over 70-plus years. Popped nails push up through the deck and crack the XT 25 tabs above them. We remove the failed shingle, reset or replace the nail, and lay a new CertainTeed OEM tab for color match.
• Flintlastic lap-seam failures on converted garages and rear additions. Those deep narrow lots Florence-Graham is known for mean rear additions are often boxed in by walls on three sides. The Flintlastic membrane that got rolled on ten or fifteen years ago bakes all summer, and when the rare winter storm arrives, the seams and termination points leak. These failures concentrate exactly where the roof meets the stucco wall.
• Presidential Shake cracking on steep front gables with soft decking. A handful of Florence-Graham homes have steeper architectural fronts with Presidential Shake. When the underlying deck has soft spots, the shingle flexes underfoot and cracks. We replace the soft sheathing before reinstalling, because no luxury shingle survives a spongy deck.
• Flashing failures where rear additions meet the main structure. Every converted garage and bumped-out addition creates a transition point, and that transition is where water finds its way in. We rebuild these flashings with OEM-compatible metal and sealants, often without touching the rest of the roof.

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

Here’s the truth most contractors don’t say out loud: Florence-Graham’s deep narrow lots mean the rear converted-garage and addition roofs are often surrounded by walls on three sides with no driveway access whatsoever. There is nowhere to put a dumpster. Nowhere to stage a boom. In neighboring cities with wider side yards, a crew rolls up, parks a truck, and works from the driveway. Here, we hand-carry CertainTeed Flintlastic rolls and shingle bundles through the house or over the fence. It changes how we stage every job: smaller crews, careful sequencing, debris bagged out by hand. On a 1948 stucco bungalow near Holmes Avenue and 92nd Street, the rear converted-garage roof had been patched with tar over old Flintlastic and leaked into the garage every winter — a situation we’ve also handled with CertainTeed in Willowbrook. We hand-carried three rolls of CertainTeed Flintlastic through the house, tore off the failed patches, replaced soft sheathing, and installed a new self-adhered membrane with new termination bars. No dumpster in the driveway, all debris bagged out by hand. That’s the Florence-Graham way to roof.

CertainTeed Models & Products We Service in Florence-Graham

We work on the full CertainTeed residential lineup: Landmark architectural shingles, XT 25 three-tab shingles, Flintlastic self-adhered low-slope membrane, and Presidential Shake luxury shingles. That covers nearly every roof in Florence-Graham, from the 1950s rental bungalow with XT 25 tabs to the converted garage with aging Flintlastic. On visible slopes, we use CertainTeed OEM shingles for color match and warranty continuity. On flashing boots and sealants, we’ll switch to quality aftermarket materials where the OEM part adds cost without real performance gain, especially on tight-budget re-roofs for small landlords and owner-occupants. The right material for your roof, not the only brand we carry — whether that’s here or CertainTeed repair in Walnut Park.

FAQs – CertainTeed Roofing in Florence-Graham

My 1950s Florence-Graham bungalow has a low-slope rear addition with old CertainTeed Flintlastic that’s bubbling – can you patch it or do I need a full replacement? Bubbling Flintlastic means moisture has worked its way between the membrane and the substrate, and a patch over a bubble will fail within a season or two. If the membrane is less than ten years old and the bubbling is isolated, we can cut out the failed section, repair the underlying deck, and re-adhere new Flintlastic. If the membrane is over twenty years old, patch money is better spent on a new Flintlastic layer. Call (877) 752-3460 for an exact assessment, free.

Do you need a boom truck or dumpster in the driveway to replace CertainTeed shingles on my narrow Florence-Graham lot? No. Most Florence-Graham lots don’t have driveway access to the rear, so we stage from the street and hand-carry materials through the house or over the fence. Debris gets bagged out the same way. It’s slower than a boom-and-dumpster setup, but it’s the only way to reach the roofs most of these homes actually have.

My CertainTeed Landmark shingles on the front roof are curling at the edges after 12 years – is that normal in Florence-Graham? Yes, and here’s why: South LA’s dry, hot climate means UV is the main wear driver. Landmark shingles on shallow-pitch roofs take direct sun at a low angle for hours a day, and after a decade the edges curl. The underlying problem is usually poor attic ventilation, which superheats the deck and accelerates the breakdown. Replacing the curled shingles and adding proper venting extends the life of the rest of the roof significantly.

Can you repair flashing around a converted-garage roof where it meets the stucco wall without re-roofing the whole house? Almost always, yes. The flashing at a wall transition is a separate failure point from the field of the roof. We cut back the failed flashing, inspect the membrane underneath, rebuild the termination with new metal and sealant, and restore the water seal. If the Flintlastic beneath is still adhered and sound, there’s no reason to touch the rest of the roof. Call (877) 752-3460 and we’ll tell you what’s actually needed.

Do you use CertainTeed XT 25 three-tab shingles for budget re-roofs on Florence-Graham rentals, or only Landmark? We install both. XT 25 three-tabs are the right call for a small rental or a tight-budget re-roof where the deck is solid and the pitch is traditional. Landmark gets recommended when the homeowner wants a thicker architectural shingle with a longer expected lifespan. We’ll show you pricing for both and let you decide, because seven brands, one contractor means no single answer gets pushed on every roof.
