CertainTeed Roofing in South San Gabriel, CA | Select Roof Repair
We provide independent CertainTeed roofing service across South San Gabriel and nearby areas like CertainTeed in Montebello, from diagnosis to repair to full replacement. What makes our CertainTeed work different here is simple: we know these 1950s – 1970s tract homes and their low-pitch addition roofs better than any manufacturer script could. Our techs see how CertainTeed shingle seals break down under this specific UV load every week, and we fix it accordingly. Call (855) 382-0485 for a straight answer and a free estimate.
Select Roof Repair works with seven major roofing manufacturers, so when you call us about CertainTeed, we’re recommending CertainTeed because it’s right for your South San Gabriel roof, not because it’s the only thing on the truck. That’s the difference between a product specialist and a roofer who actually knows what’s on top of your house. CertainTeed’s CertainTeed sales & service knowledge runs deep with us, from Landmark architectural lines down to the problematic low-slope underlayment details.
Why South San Gabriel Residents Choose Us for CertainTeed Service
Noel Carrasco grew up in the Midway City pocket just off Bolsa Avenue and has spent 25 years fixing roofs across this part of Southern California. He built Select Roof Repair on the idea that most leaks are misdiagnosed the first time. That matters in South San Gabriel specifically, because the failure here is rarely what a homeowner expects. It’s not the main shingle field. It’s the porch roof, the addition tie-in, the low-slope section that was never pitched right in the first place.
We’re roofers, full stop. No kitchens, no bathrooms, no general contracting on the side. When someone in South San Gabriel calls about curling CertainTeed tabs or a ceiling stain under the flat addition roof, we’re not sending a salesman who sees a replacement opportunity. We’re sending someone who knows which CertainTeed shingles are still structurally sound and which ones are done. Repair when it makes sense. Replace when it doesn’t.

Common CertainTeed Roofing Problems We Solve in South San Gabriel
Specific failures we see repeatedly on CertainTeed roofs in South San Gabriel, each tied to what these houses and this climate actually do:
- Lifted tabs on south- and west-facing Landmark slopes. South San Gabriel gets intense, relentless UV with almost no rain to interrupt it. CertainTeed Landmark shingle seals soften and release after years of that exposure, letting thermal cycling and Santa Ana winds lift corners on the sunny slopes. We reseal where the shingle body is still viable, and we’re honest when the field is too far gone.
- Granule loss and surface crazing on original XT-series three-tabs. Those 1950s – 1970s tract homes around 91755 often still carry their original CertainTeed XT 25 or XT 30 shingles. After 20-plus years of sun cook, the mat is past end of life. Patching buys weeks or months, not years. We say so plainly.
- Low-slope porch and addition roof ponding after rare winter storms. This is the South San Gabriel failure mode. Those flat sections were built with minimal pitch and inadequate drainage. When a real storm finally hits, they pond and leak before the shingle field even notices the rain. The fix usually starts at the tie-in.
- Flashing failures where newer two-story infill meets original CertainTeed fields. South San Gabriel has seen infill construction on tight lots. Where a newer second story ties into an older CertainTeed shingle field, the flashing detail is where water tracks under tabs during the first heavy storm. We rebuild those transitions properly.
- Wind-driven rain through worn ridge lines. The tight spacing between homes in South San Gabriel creates wind funnels between structures. Worn CertainTeed ridge caps and starter courses on older roofs give way there first.
CertainTeed Service in South San Gabriel: What Local Conditions Mean for Your Equipment
Here’s what nobody outside South San Gabriel tells you: the roof on a 1960s tract home here was never engineered for rain. The main shingle field gets sun-cooked, sure, but it sheds water fine. The problem is the porch roof, the addition roof, the flat section over the back door. These were built at minimal pitch because South San Gabriel gets maybe 15 rainy days a year. When an intense winter storm does arrive, those low-slope sections pond within hours, and water sits there long enough to find every seam, every nail hole, every seam in the old underlayment. Our CertainTeed call-outs in South San Gabriel rarely start at the shingles. They start at the low-slope tie-in. If it’s leaking, it’s telling you something. Let’s figure out exactly what.
On a 1960s stucco tract home near the 91755 core, our tech traced a ceiling stain to a low-pitch addition roof where original XT-series three-tabs had lost granules and the flat porch tie-in was ponding after a winter storm. We stripped the failing shingle section, replaced the underlayment with WinterGuard, rebuilt the flashing at the wall transition, and reset architectural shingles to blend with the intact field above. The owner got a dry ceiling and a low-slope section that finally drains instead of pooling.
CertainTeed Models & Products We Service in South San Gabriel
We work on the full CertainTeed residential range in South San Gabriel: Landmark architectural shingles, XT 25 and XT 30 three-tabs, Presidential Shake luxury architectural shingles, and WinterGuard waterproofing underlayment on low-slope and valley areas. For repairs we use CertainTeed accessory components where they make the repair last: matching shingles, WinterGuard, matching ridge and starter products. Where aftermarket flashing or vent boots outperform the OEM spec, we use those instead. That’s what independent service means. We stock common CertainTeed repair components locally so a South San Gabriel or CertainTeed repair in East Los Angeles doesn’t wait on a distribution center.

FAQs – CertainTeed Roofing in South San Gabriel
My CertainTeed Landmark shingles are lifting at the corners on the sunny side of my South San Gabriel roof – why? The sealant strips on Landmark shingles break down under years of intense UV and thermal cycling, and South San Gabriel’s south- and west-facing slopes get more of that exposure than almost anywhere else in the Los Angeles basin. The corners lift first because the seal is nearest the tab edge and heats fastest. If the shingle body is still flexible and the mat isn’t exposed, resealing can extend the field by years. If the tabs are brittle or granule-bare, the seal failure is secondary; the shingle is done. Call (855) 382-0485 for an assessment.
Why do my flat porch and addition roofs leak when my main CertainTeed shingle roof is fine? The flat or low-slope sections on South San Gabriel tract homes were built with minimal pitch because this climate rarely rains hard. When an intense storm finally hits, they pond instead of drain, and standing water finds the seams in old underlayment. The shingle field was never the problem. We rebuild those low-slope sections with WinterGuard and proper drainage so they actually shed water. Call (855) 382-0485 if your porch roof leaked this winter.
Can you match my existing CertainTeed shingles for a repair instead of replacing the whole roof? We can, when the field has life left in it. CertainTeed color lots are stable enough that we can match Landmark and XT-series shingles with reasonable accuracy, and we use matching CertainTeed ridge and starter products to keep the repair seamless. If your shingles are 20-plus years old and sun-cooked, we’ll say so and show you why a patch won’t hold. The honest answer, every time.
How does the dense, closely packed layout of South San Gabriel affect a CertainTeed reroof? Tight lots mean we’re staging materials carefully, protecting your neighbor’s fence and stucco, and scheduling work around the two-story home next door that looks right down onto your roof. We coordinate access before we start, and we keep the job site contained. It’s slower than a wide-lot reroof in a newer development, but it’s the only way to do it right here.
Should I use CertainTeed WinterGuard on my low-slope sections? Yes, and we’d argue it’s the single best preventive upgrade for a South San Gabriel tract home. WinterGuard is a waterproofing underlayment designed exactly for the low-pitch porch and addition roofs where your house is most vulnerable. On a roof built with minimal pitch and weak drainage, it’s the difference between a leak and a dry ceiling after a rare winter storm. Call (855) 382-0485 for a free assessment of your low-slope sections.
