CertainTeed Roofing in Covina, CA | Windmill Roof Repair
We provide independent CertainTeed roofing service across Covina, and the thing that sets our work here apart is simple: we know this city’s two distinct roof generations because we’ve torn off and repaired both for years. Landmark shingles on a 1960s Charter Oak tract home fail differently than Presidential shake on a 1920s downtown bungalow, and we plan every job around that reality. Call (866) 850-2496 for a free estimate from a crew that actually knows which Covina ZIP code you live in.
Why Covina Residents Choose Us for CertainTeed Service
Most roofing companies work with one or two shingle brands. We work with seven including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That matters for a CertainTeed service in Irwindale or anywhere else because we’re not here to sell you a switch to whatever’s on our truck. We’ll match your existing Landmark or Presidential profile, use genuine CertainTeed materials, and give you an honest read on whether a repair makes sense or a replacement is the only real option.
Ruben Ochoa, our owner, grew up in Pico Rivera and learned roofing through the construction technology program at East Los Angeles College. He’s spent two-plus decades on San Gabriel Valley roofs, and he’s the guy neighbors call for a second opinion when another company tries to sell them a full tear-off they don’t need. “A roof doesn’t have to be complicated – it just has to keep the water out.” That’s how we approach every CertainTeed in Azusa, Covina, and nearby communities.

Common CertainTeed Roofing Problems We Solve in Covina
- Granule loss and thermal cracking on Landmark shingles. The 91722 ZIP toward Charter Oak is thick with 1950s and 60s ranch homes now on their second or third composition roof. Decades of intense inland sun bake the asphalt until granules shed and shingles crack along the mat. We see this constantly on Landmark roofs that have outlived their expected lifespan here.
- Wind-lifted tabs and nail pops on Presidential shake. Covina’s older downtown core has plenty of high-end homes with Presidential roofs, but the original skip sheathing underneath has warped after 70 or 80 years. Santa Ana winds catch the thick Presidential tabs, and the uneven decking breaks the sealant bond. The shingle lifts, then the winter rain finds the nail hole.
- Edge curling and sealant failure after Santa Ana events. Xact and Symphony shingles are thinner-profile products, and Covina’s seasonal winds flex them repeatedly. We get calls every January from homeowners who found leaks after wind gusts lifted aged shingles that had already started curling at the eaves.
- Algae staining and blistering from poor attic ventilation. Post-war Covina homes, especially the low-slope ranch designs in 91722, often have inadequate soffit and ridge venting. Heat builds up in the attic, the shingle backs blister, and moisture trapped under the decking feeds algae growth on north-facing slopes.
- Failed flashing at transition points. Covina’s split housing stock means lots of additions. A 1940s bungalow gets a 1980s rear addition, the roofline changes, and the flashing where old meets new becomes the first failure point when concentrated winter rain arrives.
CertainTeed Service in Covina: What Local Conditions Mean for Your Equipment
On Covina’s older downtown blocks in the 91723 and 91724 ZIPs, hundreds of original clay tile roofs still sit over skip sheathing and felt that was installed before World War II. That’s a uniquely Covina problem. We regularly lift brittle, sun-baked clay tiles to reach a damaged CertainTeed shingle on an addition or a failing section of underlayment beneath, and each tile we touch risks cracking. The clay pieces on many of these 1920s and 30s homes are no longer manufactured, so a perfect match often doesn’t exist anywhere in Southern California. We stock salvaged tiles from tear-offs across the San Gabriel Valley and lift only what’s absolutely necessary, because a careless tile pull can turn a $400 leak repair into a tile-match hunt that takes weeks. Not every roofing crew in Covina carries salvaged clay on their truck. We do, because around here it’s the difference between fixing a roof and replacing one unnecessarily.
CertainTeed Models & Products We Service in Covina
We service the full residential Citrus CertainTeed service area and across Covina: Landmark architectural shingles, Presidential Shake luxury shingles, Xact shingles, and Symphony slate-look shingles. For repairs, we use genuine CertainTeed shingles and accessories to keep the color and profile matched. We keep common Landmark colors on hand for fast Covina turnaround, and we can source Presidential Shake and specialty profiles within a couple of days. We also do shingle replacement, leak repair, and roof decking replacement when the wood underneath has rotted past the point of patching. If your decking is compromised, we’ll say so plainly rather than shingle over a problem that’ll come back next winter.

AfterCertainTeed Service Pricing in Covina
CertainTeed service pricing in Covina runs roughly $350 – $900 for a typical leak diagnosis and shingle replacement, $1,100 – $2,400 for a larger localized repair with flashing or decking work, and $28,000 – $48,000+ for a full tear-off and replacement with CertainTeed Landmark or Presidential depending on square footage, decking condition, and access. At any age, two figures matter more than the shingle brand: $180 – $340 for a regular inspection, and $1,450 – $3,000 for the underlayment-to-shingle changes that keep a roof watertight.
What drives the cost here is the same thing that drives every Covina job: whether the roof sits over skip sheathing from the 1930s or plywood from 1975, and whether the last contractor flashed it right. Your free estimate includes a written line-item quote with no change orders. Call (866) 850-2496 to schedule one.

FAQs – CertainTeed Roofing in Covina
Yes, in most cases we can repair CertainTeed shingle roofs without a full replacement, especially when the failure is localized to a few shingles, a flashing point, or a section of underlayment. We use genuine CertainTeed shingles to match color and profile. But if the decking underneath is rotted or the shingles across the whole slope are granule-bare and cracking, a repair just buys you a season or two. Call (866) 850-2496 and we’ll tell you which situation you’re in after a free inspection.
On a 1950s ranch in the 91722 ZIP, cracking shingles usually mean the roof has reached the end of its service life under Covina’s inland sun and heat, so your realistic options are a targeted repair if the damage is contained to one plane, or a full re-roof with proper ventilation upgrades. Low-slope roofs trap heat faster, and we’d want to check that your attic venting is actually working before putting new shingles on a deck that’ll bake them again. Call (866) 850-2496 for an exact quote – estimates are free.
Yes, we stock salvaged clay tiles specifically because so many Covina bungalows have original clay that’s no longer made. When we lift tiles to reach a CertainTeed shingle or underlayment section underneath, we use matching salvaged pieces from our inventory rather than leaving a mismatched patch or pressuring you into a full tile replacement. It’s one of the reasons callbacks on these old roofs are rare for us.
Landmark shingles hold up well to wind events when they’re installed over sound decking with proper nailing, but on Covina homes where Santa Ana winds hit the north and east exposures hard, the failure almost always traces back to warped decking or nails that missed the nailing strip. The shingle itself is rated for high winds; the installation underneath is what fails. We’ll inspect the decking, not just the shingles, before we tell you what’s wrong.
For most 1960s ranch homes in Covina’s 91722 ZIP, Landmark architectural shingles are the best balance of cost, durability, and wind performance, but the right answer depends on your roof’s pitch, decking condition, and attic ventilation. A roof with a pitch below 3:12 may need different underlayment specs than a steeper roof, and in this part of Covina the ventilation upgrades matter more than the shingle line you pick. Call (866) 850-2496 and we’ll help you choose with the facts on the table.
