CertainTeed Roofing in West Covina, CA | Van Nuys Roofing Co
We provide independent CertainTeed roofing service across West Covina, handling full tear-offs, Roof Repair – West Covina, and inspections on the 1950s to 1970s tract homes that dominate this city. If your ranch has a failing CertainTeed roof, the odds are you’re due for a full tear-off down to sheathing, not another layover, and we’ll give you a straight answer on which one it is. Call (866) 321-6172 for a free estimate. We at Van Nuys Roofing Co are fluent in seven roofing brands, and CertainTeed is one of the ones we see most on West Covina rooftops.
We work with CertainTeed roofs daily, but we’re an independent contractor. That means no manufacturer steering, no “authorized dealer” pressure to push one product line. Just straight assessment of what your roof needs. We’re also serving the broader region through our CertainTeed sales & service division, and this page is specifically about what CertainTeed owners in West Covina face.
Why West Covina Residents Choose Us for CertainTeed Service
Rick Dominguez, our owner, learned roofing the old way, on tear-offs and re-roofs across the San Gabriel Valley, including CertainTeed repair in La Puente. He grew up off Sepulveda Boulevard in Van Nuys and spent two decades on rooftops before starting Van Nuys Roofing Co. His rule is simple: “If it doesn’t need replacing, I’m not going to tell you it does.” That’s the approach we bring to every CertainTeed roof in West Covina, whether it’s a 1964 ranch in 91790 or a hillside home off the 91791 foothills.
We inspect first, recommend second. A lot of roofers won’t offer a standalone inspection without angling for a replacement sale. We do. If your CertainTeed shingles have five years left, we’ll tell you that and give you a maintenance list. If they’re done, we’ll show you why before we ever talk price. And because our crew works with seven major roofing brands, we’re not married to CertainTeed when a different material would serve your house better. Your roof, your material choice.
Repair or replace, we’ll tell you which one actually makes sense. That’s the whole job. Call (866) 321-6172.

Common CertainTeed Roofing Problems We Solve in West Covina
Here’s what actually goes wrong on CertainTeed roofs in this city. Not the generic stuff, the West Covina-specific stuff:
- Brittle second- and third-layer three-tab shingles. In West Covina’s inland valley heat, organic-mat CertainTeed three-tab shingles from the 1960s and 70s lose their sealant strips and go brittle. The tabs lift in Santa Ana winds and tear field shingles off while the layer below stays intact. We see this constantly on 1958 to 1975 ranch tracts.
- Heat-baked west slopes with granule loss. The afternoon sun on west-facing slopes in West Covina pushes deck temperatures well above ambient. Decades of that cook CertainTeed granules loose and dry out the mat. The result: bald patches and exposed reinforcement long before the roof actually leaks.
- Fastener pull-through on cooked decking. Original CertainTeed installations over 1-inch or skip sheathing show sagging between rafters after 40-plus summers of heat. The nails lose grip, the deck sags, and leaks track to the roof deck itself, not to a missing shingle you can spot from the ground.
- Sealant failure at ridge caps and hips. Hot, dry cycles crack the sealant on ridge caps and open nail heads at hips and valleys. Then the first winter storm drives water into the fascia and eaves. It’s the only real rain load these roofs see all year, and it lands exactly where the sealant gave out.
- Flashing failures at attached-garage and low-slope transitions. Many West Covina ranches have attached garages with low-slope sections. CertainTeed Flintlastic modified-bitumen membrane handles these, but original torch-down details fail at the transition seams, and that’s where water gets in.
Every one of these failure modes has a fix. Some are local repairs. Most of the time on West Covina’s aging tracts, the honest answer is tear-off and replacement. We’ll walk you through the difference.
CertainTeed Service in West Covina: What Local Conditions Mean for Your Roof
Here’s the thing about West Covina that changes how we approach CertainTeed service in Irwindale and here. The city went up almost entirely in the 1950s through 1970s tract booms. Unlike coastal cities where fog keeps roofs cooler and wetter, West Covina sits in a hot inland valley at the foot of the San Gabriel Mountains. Roof deck temperatures run well above ambient for months on end. The signature West Covina job is a tear-off on a 1958 to 1975 ranch where the original CertainTeed shingles are already gone and a second layer, sometimes a third, is now failing. That’s not a roof you re-cover. That’s a roof you strip to the sheathing, inspect the deck, replace what’s soft, and rebuild.
And there’s a split within the city. The homes along the southern and hillside edges of 91791 back up to the wildland interface. Those roofs need Class A fire-rated assemblies with ember-resistant venting. The flat central tracts of 91790 and 91792 rarely do. Same CertainTeed brand, different installation spec, and it matters for code, insurance, and warranty eligibility. On a 1962 ranch off Cameron Avenue in 91790, we tore off two stacked layers of brittle CertainTeed three-tab down to the original 1-inch sheathing. The south-slope boards were delaminated and fasteners were pulling through from decades of heat. We replaced the soft decking, re-nailed the sound boards, and installed CertainTeed Landmark architectural shingles in a Title 24 cool-roof color over full synthetic underlayment, with new ridge venting to move the attic heat that had been cooking the old shingles for decades. That’s a West Covina roof job, start to finish.
We serve all of West Covina from West Covina service area coverage, so if you’re in 91790, 91791, 91792, or 91793, we’re already familiar with the housing stock and code landscape.
CertainTeed Models & Products We Service in West Covina
We service the full range of CertainTeed products this city actually has on its roofs:
- CertainTeed Landmark architectural shingles. The dominant replacement choice on West Covina tract ranches. We install these regularly and know the nailing pattern, exposure, and ventilation requirements.
- CertainTeed XT 25 and older organic-mat three-tab shingles. Still on second-layer 1950s to 70s roofs throughout 91790 and 91792. Brittle, fragile, and not something you patch carelessly.
- CertainTeed Presidential Shake and Presidential TL. Luxury shingles on upgraded homes and hillside properties in 91791.
- CertainTeed Flintlastic modified-bitumen membrane. Used on low-slope porch and attached-garage sections, a common feature on post-war West Covina ranches.
We install CertainTeed-branded shingles, underlayments, and accessory components to keep the system warranty-eligible. We don’t mix OEM CertainTeed with off-brand flashing and call it a CertainTeed roof. If your roof gets a CertainTeed shingle, it gets CertainTeed accessories. And we won’t shingle over soft or delaminated sheathing just to save a bundle. If the deck is bad, it gets replaced, because a second layer over rot is a leak we’ll be back for.

AfterCertainTeed Service Pricing in West Covina
Roofing prices in West Covina follow the scope of work, not the brand on the shingle. A full tear-off and CertainTeed Landmark replacement on a typical 1,200 to 1,800 square foot ranch runs somewhere in the $14,000 to $24,000 range, depending on deck repair, slope complexity, fire-rated underlayment needs in 91791, and whether you need Class A upgrades. Local repairs, flashing work, and ridge cap replacement run far lower, often $400 to $1,800 depending on what we find.
What drives the cost on West Covina homes specifically is the deck condition. Forty to sixty years of valley heat means we often replace sections of sheathing, re-nail others, and upgrade ventilation, all of which is real work that shows up in the estimate. We give you written line-item quotes, no change orders unless you change the scope. Call (866) 321-6172 to schedule a free estimate and we’ll walk the roof with you.

FAQs – CertainTeed Roofing in West Covina
My West Covina ranch already has two layers of CertainTeed shingles – can you just add a third?
No. California building code limits roof coverings to two layers, and a third layer on a 1960s West Covina tract home would trap heat, overload the framing, and void any warranty. What the roof needs is a full tear-off down to sheathing so we can inspect the deck and start fresh. Call (866) 321-6172 and we’ll confirm what’s up there, for free.
Do I need a Class A fire-rated CertainTeed roof in 91791 if I’m near the hills?
If you’re in the wildland interface zone along the southern and hillside edges of 91791, yes. West Covina enforces WUI (Wildland Urban Interface) codes in those areas, which means Class A assemblies and ember-resistant venting. We’ll check whether your specific parcel falls in that zone and build the appropriate CertainTeed system. Call (866) 321-6172 for a precise answer on your lot.
What’s the difference between the CertainTeed three-tab on my roof and Landmark architectural shingles?
The three-tab is a single-layer, flat shingle with a shorter lifespan and more vulnerability to heat and wind. CertainTeed Landmark is a laminated architectural shingle with better wind ratings, better granule adhesion, and a more dimensional look. On West Covina’s hot, wind-exposed roofs, Landmark holds up measurably better, and it’s what we recommend on most replacement jobs here.
My CertainTeed shingles look fine but the ceiling stains appeared after the first winter rain – what failed?
Most likely it’s the underlayment, flashing, or deck, not the shingle surface. On West Covina roofs we often find the original CertainTeed installation had failed sealant at ridge caps and hips, and the first meaningful rain of the year drove water in through those open nail heads. The shingles look fine because the shingles are fine, but the system failed. We’ll find it during an inspection.
Does a new CertainTeed roof have to meet Title 24 cool-roof rules in West Covina?
Yes. Title 24 cool-roof requirements apply to most residential re-roofs in West Covina, which means choosing a CertainTeed shingle color with the right solar reflectance and thermal emittance ratings. We can guide you through the approved color options and ensure your roof passes inspection. Estimates are free – call (866) 321-6172.
