CertainTeed Roofing in South Gate, CA | Select Roof Repair
We’re an independent roofing contractor that installs, repairs, and replaces CertainTeed shingle and flat-roof systems across South Gate and nearby communities including Huntington Park CertainTeed service areas. What makes our CertainTeed work different here is simple: we’ve torn off and rebuilt roofing on hundreds of South Gate’s 1940s and 1950s tract houses, so we know exactly how CertainTeed products behave on shallow-pitch decks and unpermitted additions. If you need a straight answer on whether your CertainTeed roof can be repaired or should come off, call (855) 382-0485 for a free inspection and estimate. Noel Carrasco, who runs our crew, will make sure the diagnosis comes from what we find on the roof, not from a sales script.
Why South Gate Residents Choose Us for CertainTeed Service
Most roofing companies in South Gate work with whatever shingle brand the supply house has on the shelf that week. We’re different because CertainTeed is one of the seven manufacturers we work with deliberately. CertainTeed Landmark shingles, XT 25s from older re-roofs, Flintlastic membranes on flat additions, and presidential-style shingles on steeper sections all age differently in this inland basin climate. Choosing us means you get someone who can tell you why your Landmark shingles are curling at the edges while your neighbor’s newer roof isn’t. And when we repair, we use CertainTeed OEM shingles and accessories whenever possible. That matters because a mismatched aftermarket shingle won’t seal correctly and typically fails within a couple of seasons.
We cover all of South Gate, 90280, from the dense blocks around Tweedy and Atlantic to the quieter residential streets further south. You can also see our broader CertainTeed sales & service page if you want more detail on which products we handle beyond the South Gate area.

Common CertainTeed Roofing Problems We Solve in South Gate
- Landmark granule loss and edge curling on low-slope roofs. South Gate’s hot, dry summers create intense UV stress, and when attic ventilation is poor, Landmark shingles on shallow-pitch decks bake from both sides. We see premature granule loss and raised edges within 12 to 15 years on roofs that should last 20-plus.
- XT 25 organic-mat cracking and blistering. Many 1980s re-roofs in South Gate used CertainTeed XT 25, which has an organic felt mat. That mat can’t handle the basin’s heat cycling as well as modern fiberglass mats. We regularly find dry cracks and blisters on XT 25 roofs that aren’t even at their warranty limit.
- Flintlastic membrane blisters and seam splits on flat additions. Converted garages and added rooms with low-slope Flintlastic roofs are everywhere near Atlantic. When those additions were never insulated or vented properly, heat builds underneath and the membrane blisters, then splits at the seams.
- Presidential shingle wind uplift at rake edges. During Santa Ana events, steep sections near Atlantic can lose shingles at the rake edges if the starter course wasn’t sealed or the original installer skipped edge cement. We repair these with OEM Presidential shingles and proper edge detailing.
- Layered reroofs hiding deck damage. On the dense blocks near Tweedy, we routinely find two or three layers of old shingles over dry-rotted sheathing. South Gate’s older tract houses often got reroofed over, never torn off, so we catch deck problems every time we open one up.
CertainTeed Service in South Gate: What Local Conditions Mean for Your Roof
On the dense blocks near Tweedy and Atlantic, and on similar streets where we do CertainTeed repair in Walnut Park, roofs are so close together that tear-off debris and hot-mop kettle smoke drift to neighbors almost immediately. That has a direct effect on how CertainTeed work plays out here. When we do a Landmark tear-off or a Flintlastic flat-roof repair in this part of South Gate, we tarp the perimeter, schedule debris runs daily instead of letting piles sit, and coordinate any hot-work with the neighbor’s windows. On larger-lot homes further south in South Gate, you don’t need that level of care. But on a 5,000-square-foot lot with a house eight feet from the property line, a windy tear-off day can send old shingle granules onto three neighbors’ cars. We learned that lesson years ago. It’s why we now plan tear-offs around the wind forecast and keep a crew member on sweep duty. It’s not something a roofer from outside South Gate would think about until it’s already a problem.
CertainTeed Models & Products We Service in South Gate
We install and repair the full CertainTeed shingle and membrane lineup common on South Gate housing: Landmark architectural shingles, XT 25 three-tabs from older re-roofs, Flintlastic SA and base sheets for flat and low-slope additions, and Presidential shake-style shingles on steeper gable sections. For repairs, we use CertainTeed OEM shingles, ridge caps, flashing, and vent boots because matching the original product ensures proper integration with existing layers. We keep common Landmark colors stocked locally so a same-week repair doesn’t get delayed waiting on a distributor order. If your roof has a discontinued color or product, we’ll source it through CertainTeed’s network and give you an honest lead time up front.

What drives cost in South Gate is usually deck condition and layer count. A roof that’s been reroofed twice hides more deck repair. A roof with an unpermitted flat addition over a converted garage adds membrane work.

FAQs – CertainTeed Roofing in South Gate
Most Landmark shingle problems on low-slope roofs start with ventilation, not the shingle itself. If we get to it before the deck is rotted, spot replacement of damaged shingles plus added intake and exhaust venting can buy a decade or more. If the deck is gone or the shingles are curling across the whole field, a tear-off is the only fix that holds. We’ll show you photos of what we find and give you both options with pricing. Call (855) 382-0485 for a free inspection.
XT 25 shingles have an organic felt mat, and South Gate’s hot, dry summers bake them in a way organic mats can’t endure as long as the fiberglass mats in modern shinglesYour neighbor’s newer CertainTeed roof almost certainly has a fiberglass mat. The cracking you see is the organic mat drying out and the asphalt losing flexibility. Repairing individual cracked tabs is possible, but once it’s widespread, replacement is the honest recommendation.
No attic access means we open a small section of the membrane from above to inspect the deck and insulation condition underneath. On South Gate garage conversions, we often find no insulation and no venting, which is exactly what caused the Flintlastic to blister in the first place. We patch the membrane, then add low-profile vents and insulation where the structure allows. It’s the only way to stop the same blister from returning.
OEM whenever the product is in production. CertainTeed’s flashing, ridge caps, and vent boots are engineered to seal with their shingles, and an aftermarket flashing that doesn’t match the profile will leak faster. If your CertainTeed line is discontinued, we’ll tell you and source the closest compatible OEM from CertainTeed’s current catalog rather than defaulting to generic.
The house-to-house spacing changes how we plan the whole job. On blocks near Tweedy and Atlantic, we tarp the yard and the neighbor’s side, schedule tear-off around the wind, and clean the street daily. We also coordinate hot-mop kettle work carefully because the smoke travels fast. Those are the details that keep a South Gate reroof from becoming a dispute with the next door neighbor. Call (855) 382-0485 and we’ll walk your specific block during the free estimate.
