CertainTeed Roofing in Covina, CA | Huntington Beach Roofers
We provide independent CertainTeed roofing service throughout Covina, including the 91722, 91723, and 91724 ZIP codes. The thing that sets our CertainTeed work apart here is simple: we know exactly how these shingles fail on Covina’s specific mix of 1950s – 70s tract homes and citrus-era bungalows before we ever set foot on the ladder — the same expertise we bring to our Citrus CertainTeed service. That means faster diagnosis, fewer surprise change orders, and a repair-or-replace call you can actually trust. Call (833) 467-4901 for a free estimate.
Why Covina Residents Choose Us for CertainTeed Service
Neil Stratton runs our crew, and he grew up around roofs that leaked. Half the houses on his street in Bolsa Chica seemed to have a tarp on them at any given time, and that turned into two-plus decades of tearing off, re-decking, and reinstalling shingle systems from seven manufacturers. CertainTeed is one of the brands we know deepest, because we’ve pulled apart enough failed Landmark and XtraDefense installations across the San Gabriel Valley to understand exactly how they behave under Covina’s specific conditions. We’re an independent CertainTeed service provider. Not authorized, sponsored, or endorsed by CertainTeed. And that independence matters in Covina, where you have tract homes from the 1960s next to bungalows from the 1920s and each one needs a different answer. We inspect first and recommend second. That’s how Neil runs every job, and it’s why homeowners here call us back when the next issue shows up.
Our CertainTeed sales & service work covers everything from targeted flashing repair to full tear-offs, always using OEM components or aftermarket materials that meet or beat CertainTeed’s published requirements.

Common CertainTeed Roofing Problems We Solve in Covina
CertainTeed makes solid materials, but Covina’s climate and housing stock create some repeat failure patterns we see again and again. Here’s what’s actually happening on roofs across the 91722, 91723, and 91724 ZIPs:
- Granule loss and edge curling on Landmark shingles. South- and west-facing slopes in Covina bake under San Gabriel Valley sun, and attic heat accelerates asphalt oxidation from below. After 12 to 15 years, Landmark architectural shingles on that exposure start shedding granules into the gutters and curling at the edges. That’s not a defect, it’s UV load and poor attic ventilation working together.
- XtraDefense blistering over skipped underlayment. Many 1970s Covina tract homes were originally reroofed with thin or skipped underlayment because the code wasn’t what it is now. XtraDefense shingles installed over that weak base blister and crack at the shadow line, and the first Santa Ana wind peels a corner straight back. We find this constantly in the 91723 ZIP.
- Presidential SolarReflective seal-strip failure on low slopes. Covina’s citrus-era bungalows near downtown often have shallow-pitch roof sections. Presidential SolarReflective shingles trap heat and debris on those slopes, and the seal strip eventually gives way. Wind uplift at the rake edge is the usual first sign.
- Tab shingle failure at valleys and vent boots. Older CertainTeed tab shingle roofs on bungalows frequently start leaking at valley transitions and plumbing vent boots. Winter storm water tracks underneath and hits original 1x sheathing that’s been drying out for seventy years.
- Corner peel after the first big rain. Covina’s rain comes in a few concentrated winter storms, so leak calls cluster right after the first big one. A corner that held through summer heat suddenly lets go when the decking swells and the old nails back out.
CertainTeed Service in Covina: What Local Conditions Mean for Your Equipment
Here’s the thing about Covina that doesn’t show up in a roofing manual: on the same block, you’ll find a 1968 tract home with a steep 6-in-12 pitch sitting two doors down from a 1920s bungalow with a nearly flat 3-in-12 section. That changes how a CertainTeed crew works. On the steep tract tear-off, it’s ladder work, tear-off, full synthetic underlayment, and Landmark architectural shingles. On the bungalow next door, we’re re-decking a shallow section and often recommending a different CertainTeed line entirely because SolarReflective shingles on that pitch collect debris and heat. Neighboring cities like West Covina or Glendora are mostly postwar tracts with fairly uniform pitches. Covina’s older downtown-adjacent core mixes the housing types in a way that demands a contractor who switches between approaches without switching crews. We do both jobs with the same team, and that means the bungalow gets the same attention as the tract home, not a subcontractor who only knows one roof shape. Our work across the Covina service area reflects that daily reality.
CertainTeed Models & Products We Service in Covina
We work on the full range of CertainTeed roofing products found on Covina homes. That includes Landmark architectural shingles, the go-to for most of the postwar tracts here. XtraDefense shingles, which came along later and are now aging into their failure window on houses reroofed in the early 2000s. Presidential SolarReflective shingles, which show up on bungalows and custom builds. And Cedar Impressions siding-style accents that sometimes need integration or replacement during a reroof. We keep standard Landmark colorways and CertainTeed accessory components readily available for Covina jobs, and when OEM parts aren’t the right call, we specify aftermarket underlayments and flashings that meet or exceed CertainTeed’s published requirements. Our service covers full roof replacement, roof decking replacement, and flashing repair specifically.

AfterCertainTeed Service Pricing in Covina
We get asked about cost constantly, and the honest answer is that it depends on what we find when we get on the roof. A targeted flashing or valley repair is a smaller job. A full tear-off and re-deck on a 1970s Covina tract home that turns out to have skipped underlayment is a bigger one. What we can tell you is this: our estimates are free, they’re line-item, and they don’t change unless we open up the roof and find something nobody could have seen from the ground. Factors that drive cost include roof pitch, decking condition, the CertainTeed line you choose, and whether we’re replacing one slope or the whole system. We don’t push full replacements when a repair makes sense, and we don’t patch over decking that’s already failing. Call (833) 467-4901 and we’ll walk the roof with you before quoting anything.

FAQs – CertainTeed Roofing in Covina
It depends entirely on what’s underneath. We’ve answered this exact call on a 1968 tract home in the 91722 ZIP — and similar calls through our West Covina CertainTeed service — after the first big winter rain, and what looked like a simple corner repair turned into a full tear-off of the affected slopes once we found the shingle nailed over skipped underlayment with cracked sheathing underneath. If the decking is solid and the underlayment is intact, a targeted repair is fine. If we find thin or skipped underlayment, a re-deck is the only fix that won’t fail again in the next Santa Ana. Call (833) 467-4901 and we’ll tell you which one you’ve got before we recommend spending anything.
Your west slope takes the full afternoon sun in the San Gabriel Valley, and attic heat rises to that side of the roof deck. That heat bakes the shingles from below while UV hits them from above, which doubles the oxidation rate on the asphalt. Granule loss, cracking, and curling show up on that exposure years before the north or east slopes. Improving attic ventilation helps, but if the shingles are already past 15 years, replacement of that slope with matching CertainTeed Landmark is usually the practical answer. Call us for an exact assessment.
We don’t install shingles over existing tile, ever. Concrete tile is heavy, and the decking on older Covina bungalows often wasn’t framed for the added load of a tile-over. We remove the tile, inspect the sheathing, repair or replace what’s failed, and then install the CertainTeed system over a proper underlayment. Putting shingles over tile hides deck problems you can’t see and almost always shortens the life of the new roof. We’ll give you an honest look at what’s underneath before we recommend the approach.
More often than not, it’s flashing. Valleys are where two roof planes meet and they concentrate water flow during Covina’s heavy winter storms. The shingles at the valley aren’t usually the first thing to fail; it’s the metal flashing underneath, the sealant at the valley edges, or the underlayment detail that was done wrong decades ago. We’ve seen plenty of otherwise-sound CertainTeed roofs leaking at valleys because a previous crew skimped on flashing. We diagnose the actual source before replacing anything, and if it’s confined to the valley, we repair the flashing rather than tearing off good shingles. Estimates are free, so call (833) 467-4901.
Yes, in most cases. CertainTeed Landmark and XtraDefense colorways are still available for most of the lines installed across Covina in the last 15 to 20 years. Older 1970s tab shingles are harder because those color lines were discontinued, but we carry and source close-match options when an exact match isn’t manufactured anymore. The bigger issue is sun fading: a west slope that’s been baking for a decade won’t match a brand-new bundle of the same color. We’ll show you samples against your existing roof before anyone climbs a ladder. Call us to schedule a color match and free estimate.
