CertainTeed Roofing in Los Angeles, CA | Buena Park Roof Repair
We service and repair CertainTeed roofing systems across Los Angeles, from the 1920s bungalows of South LA to the hillside homes along the 90039 corridor, and we also offer Koreatown CertainTeed service. We’re an independent CertainTeed service provider, not manufacturer-authorized, and that independence is exactly why homeowners call us: we’ll tell you what your roof actually needs, whether that’s a localized repair or a full re-roof. The one thing that makes our CertainTeed work different here is that we know how these shingles fail on this city’s specific housing stock. Call (866) 282-5070 for a straight answer.
Why Los Angeles Residents Choose Us for CertainTeed Service
We cut our teeth on the CertainTeed systems already nailed to South LA and Eastside roofs, the ones installed during the 1990s and 2000s re-roofing wave that swept through the bungalow blocks. Rick Dunnigan, our owner, grew up in Buena Park and spent weekends as a kid helping his uncle patch ranch-style roofs along Orangethorpe Avenue. That hands-on start never left him. Today we bring the same repair-first mindset to Los Angeles: we source genuine CertainTeed shingles and accessories when the color lot is still in production, and match discontinued colors with salvaged or closely-lotted material rather than mixing unrelated brands on the same plane. Homeowners in Los Angeles choose us because we’re honest about scope. If the field is sound and the failure is localized to flashing, valleys, or vents, we repair it. If laminate granule loss or underlayment age means patching just buys a season, we’ll say so. No upsell, no padding.

Common CertainTeed Roofing Problems We Solve in Los Angeles
CertainTeed makes solid products. But every product has failure patterns, and Los Angeles’s climate accelerates them. Here’s what we see most often:
- Rapid granule loss on Landmark architectural shingles. South LA’s intense UV and long dry summers bake the granule coating off Landmark shingles faster than most homeowners expect. Once the fiberglass mat is exposed, the shingles start curling at the eaves and the roof loses its fire rating, which matters in hillside and wildland-interface zones.
- Presidential Shake lifting and cracking at hips and ridges. The high-profile lines, Presidential Shake and Presidential Shake TL especially, catch Santa Ana wind like a sail. Where installers hand-sealed instead of tab-locking, the shingles shear at the ridge line. We see this on hillside homes in the 90039 ZIP and throughout the older construction corridors.
- Telegraphed decking on 1920s plank-and-batten substrates. CertainTeed architectural shingles installed over old plank-and-batten decking will eventually telegraph the gaps between boards. The shingles crack along those lines, and nail pops follow. This is a South LA and Eastside classic, because the original decking was never replaced during re-roofs.
- Flintlastic ponding on flat rear additions. Those low-slope hot-mop tar roofs over 1920s rear additions were pitched flat to the original plans. When homeowners or contractors cap them with Flintlastic or another modified bitumen, water ponds, seams open, and blisters form in winter rain. We re-pitch or add positive drainage rather than just recoating.
- Discontinued color matching on partial repairs. CertainTeed discontinues color lots regularly. When a homeowner needs a repair on a Landmark roof installed ten years ago, finding that exact color takes legwork. We match salvaged or closely-lotted material instead of laying a mismatched patch across the visible slope.
CertainTeed Service in Los Angeles: What Local Conditions Mean for Your Equipment
Here’s what a generic CertainTeed page never tells you: in the 1910s-1940s bungalow blocks of 90003 and 90011, a large share of CertainTeed shingle re-roofs are actually tile-to-shingle conversions. The original clay barrel tile is discontinued or mismatched beyond repair, and stripping 80-plus-year-old tile down to the skip sheathing is a different job entirely from a straightforward overlay. That means we spend as much time re-decking as we do installing, because the old plank-and-batten substrate was never meant to carry modern architectural shingle loads. In the 90001 and 90003 corridors, the rear additions are a second story to the story: flat hot-mop caps laid to the original 1920s pitch pond water after every decent rain. We re-pitch, install scuppers with positive drainage, and cap with Flintlastic SA, which is designed for low-slope. Los Angeles roofing work is never just shingles. It’s decking, drainage, and discontinued tile archaeology. For a deeper look at what that means for CertainTeed sales & service, read on.
CertainTeed Models & Products We Service in Los Angeles
We work on every CertainTeed line you’re likely to find on a Los Angeles roof, from the Landmark architectural shingles that dominate 1990s and 2000s re-roofs to the heavier luxury profiles that showed up on hillside remodels:
- Landmark and Landmark Pro architectural shingles, including Xactimate-referenced replacement work after storm claims.
- Presidential Shake and Presidential Shake TL, the high-profile laminates that fail at hips and ridges under Santa Ana uplift.
- Grand Manor luxury shingles, where we handle cracked tabs and ridge repairs without forcing a full replacement.
- Flintlastic and Flintlastic SA modified bitumen for low-slope caps over rear additions and garages.
On parts, our approach is simple: genuine CertainTeed components when production still runs the color lot, and salvaged or closely-lotted matches when the line is discontinued. We don’t mix brands on the same plane. We also keep common accessory stock, including ridge cap, starter strips, and CertainTeed underlayment, so Los Angeles repairs don’t stall waiting on a distributor. If you’re in the neighboring Azusa area, that same parts discipline applies at our CertainTeed service in Azusa.

AfterCertainTeed Service Pricing in Los Angeles
CertainTeed roofing costs in Los Angeles run the same range as most quality architectural shingle work, but the specific numbers depend on what’s underneath. A straightforward repair, like a flashing replacement or a localized shingle patch, typically runs $350 to $900. A full re-roof with Landmark architectural shingles on a standard single-story bungalow falls between $9,000 and $16,000 depending on decking condition. Where Los Angeles costs climb is on the conversions: stripping old clay tile, re-decking over plank-and-batten, and re-pitching flat additions. That work adds $4,000 to $9,000 or more, because the original framing was never meant for modern loads. A free estimate from us includes a written line-item breakdown and an honest recommendation on repair versus replacement. We’ll tell you what it actually needs. Call (866) 282-5070 for a quote.

FAQs – CertainTeed Roofing in Los Angeles
No. The old clay barrel tile sits on skip sheathing, not a solid deck, and the tile profile creates an uneven surface that voids any manufacturer warranty on an overlay. We strip the tile, inspect the sheathing, and re-deck before installing Landmark. It costs more up front, but it’s the only way the roof doesn’t fail inside five years. Call (866) 282-5070 for a site assessment.
High-profile shingles catch wind like a sail, and if the original installer hand-sealed instead of tab-locking the ridge and hip, the wind works them loose every season. We repair the lifted sections and tab-lock the full ridge line, which is the only permanent fix for that failure mode. The repair usually runs $400 to $1,200 depending on ridge length and access.
Yes, but only if the substrate has positive drainage. Flintlastic SA is a true self-adhered modified bitumen designed for low-slope, but laying it over a ponding 1920s flat roof just moves the leak around. We re-pitch the addition with tapered insulation or a new scupper, then install Flintlastic SA. That’s the difference between a cap that lasts and a cap that blisters in two winters. Call (866) 282-5070 and we’ll assess the slope before quoting.
Partly. LA’s UV is brutal, and CertainTeed Landmark shingles installed in the 2000s are hitting the age where granule loss accelerates. But if you’re seeing bare fiberglass mat in patches rather than uniform wear, you may also be dealing with a manufacturing lot issue or installation problem. We also handle CertainTeed repair in Silver Lake. We inspect the pattern and tell you whether the roof has years left or needs replacement. Estimates are free.
Yes. On any tile-to-shingle conversion or full re-roof where we’re opening the deck, we install CertainTeed synthetic underlayment as the base layer. It’s part of keeping warranty integrity intact and giving the new shingles a clean substrate. We don’t cut corners on the layer nobody sees.
