CertainTeed Roofing in El Monte, CA | Van Nuys Roofing Co
We provide independent CertainTeed roofing service across El Monte, from full tear-offs to targeted repairs. The thing that separates us from a generic CertainTeed page: we know how Landmark and Flintlastic actually behave on the low-slope, 60-to-70-year-old ranch roofs that dominate this city. Call (866) 321-6172 for a free estimate on any CertainTeed roof issue.
Van Nuys Roofing Co carries seven major roofing brands, including CertainTeed sales & service, so we don’t steer you toward one manufacturer. We steer you toward what your roof actually needs. Rick Dominguez, our owner, spent years on rooftops across the San Gabriel Valley before starting this company, and he’s known for being straight about what needs fixing versus what can wait. That’s how we approach every CertainTeed job in El Monte.
Why El Monte Residents Choose Us for CertainTeed Service
CertainTeed makes good roofing materials, but a shingle is only as good as the deck under it and the crew installing it. Around here, that’s the whole ballgame. El Monte’s housing stock is dominated by 1940s-to-1960s single-story stucco ranches on small lots, many with shallow pitches and original wood sheathing. A certain percentage of them still have their original CertainTeed roof from a re-roof decades ago, and when we walk those roofs, we know what we’re looking at.
We’ve torn off and rebuilt CertainTeed systems across 91731, 91732, 91734, and 91735, plus CertainTeed in North El Monte and surrounding areas. We know how Landmark architectural shingles age on a west-facing slope in August, and we know when Flintlastic membrane is the right call instead. That’s not showroom knowledge. It’s the kind you get from standing on a 1954 ranch off Valley Boulevard and feeling the tabs crack under your boots. If it doesn’t need replacing, we’re not going to tell you it does.

Common CertainTeed Roofing Problems We Solve in El Monte
CertainTeed roofs fail in specific ways here. Not generic ways; specific to the San Gabriel Valley sun, the Santa Ana winds, and the vintage of the homes. These are the issues we walk into most often:
- Sun-baked tab loss on west- and south-facing Landmark slopes. The UV here doesn’t fade shingles; it cooks them. Thermal cycling cracks the tabs while the north slope on the same roof still looks serviceable. We see this constantly in El Monte’s post-war tracts, where wide ranch roofs sit exposed all afternoon.
- Wind-lift and creased shingles after Santa Ana events. Winds funneled through the San Gabriel Valley hit these low, wide roofs hard. Edge nailing and starter courses on 1950s construction were never built for it. Shingles lift, crease, and then the next wind event peels them back further.
- Brittle, curling CertainTeed field shingles that shatter on tear-off. Forty-plus years of heat on a shallow-pitch roof with poor attic ventilation does that. You can’t patch a shingle that turns to fragments when you touch it; you replace the field.
- Failed original underlayment and soft fascia at the eaves. Decades of sun plus occasional El Niño rain rots the deck under a shingle field that still looks intact from the ground. The homeowner sees a decent roof; we feel the flex at the eave.
- Low-slope sections where shingles were never the right product. A lot of El Monte ranch roofs fall at or below the minimum pitch CertainTeed rates architectural shingles for. Shingling them is a warranty problem waiting to happen. We fix it with Flintlastic.
CertainTeed Service in El Monte: What Local Conditions Mean for Your Equipment
Here’s the thing about El Monte that doesn’t show up in a CertainTeed brochure: the post-WWII ranch tracts in 91731 and 91732 were built low-slope and shallow-gable because materials were cheap and the era demanded speed. The pitch on many of these roofs falls at or below the minimum CertainTeed rates architectural shingles for. That’s not a minor detail; it’s a code and warranty problem. A roofer who bids a “re-shingle” on a 2:12 pitch with Landmark is either not looking at the roof or not telling you the truth. We’re the crew that tells you. On those sections, we install CertainTeed Flintlastic modified-bitumen membrane instead, which is actually rated for low-slope applications. On a 1954 ranch off Valley Boulevard in 91732, we walked a CertainTeed Landmark roof the homeowner wanted re-shingled and found the west-slope tabs shattered underfoot while the sheathing at the eave flexed. We’ve seen the same pattern on homes needing South El Monte CertainTeed service. Decades of valley sun had cooked the plywood and the original fascia. We tore off to the rafters, replaced the soft decking and fascia, corrected the low-slope section with Flintlastic rather than shingle, and re-shingled the steep planes in Landmark. That job started as a shingle swap and ended as a proper full replacement, because that’s what the roof actually needed.
CertainTeed Models & Products We Service in El Monte
We work on the full CertainTeed residential lineup you’re likely to find in El Monte:
- Landmark architectural shingles: the most common CertainTeed product on local ranches, and the one most affected by UV and pitch issues here.
- Presidential Shake and Presidential TL: a heavier, thicker shingle some El Monte homeowners upgraded to for looks and wind resistance.
- Flintlastic modified-bitumen membrane: the right product for low-slope sections where shingles don’t belong.
- XT25 and RoofRunner underlayment: original and replacement underlayments we deal with when the deck is exposed.
We install genuine CertainTeed materials when the product fits the roof. We don’t push aftermarket-equivalent parts to save a few dollars, and we don’t put shingles on a membrane slope to save time. If you have a mixed-pitch roof, we’ll spec the right product for each plane separately, which is what a real CertainTeed service provider should do. For fast turnaround in El Monte and CertainTeed in Temple City, we keep common CertainTeed colors and Flintlastic materials stocked.

AfterCertainTeed Service Pricing in El Monte
The cost of CertainTeed roofing work in El Monte depends on three things: whether it’s a repair or a full tear-off, the pitch and deck condition, and how much membrane versus shingle your roof requires. A simple flashing repair or a few replacement tabs runs on the low end. A full tear-off with re-decking on a 1950s ranch runs significantly higher, because you’re not just paying for shingles; you’re paying for the rotted sheathing, the fascia replacement, and the low-slope membrane correction that the original build never accounted for. We give you a written line-item quote after walking the roof, not a ballpark over the phone. Call (866) 321-6172 to schedule a free estimate. We’ll walk it with you if you want, and you’ll see what we see.

FAQs – CertainTeed Roofing in El Monte
No, not on the low-slope sections. Landmark architectural shingles are rated for steeper pitches, and many El Monte ranch roofs fall below that minimum. We install CertainTeed Flintlastic modified-bitumen membrane on those planes instead, which is the correct product for the pitch and keeps your warranty valid. Call (866) 321-6172 and we’ll measure the pitch before you spend a dollar.
Because they’ve been baking in San Gabriel Valley heat for decades on a shallow-pitch roof with inadequate attic ventilation. The asphalt loses its volatiles, the tabs get brittle, and they shatter under a tear-off crew’s boots. It’s not a CertainTeed defect; it’s 40 years of UV and thermal cycling on a roof built to 1950s standards. A shingle that shatters on tear-off confirms the removal was overdue.
Yes, and it comes down to housing stock. El Monte’s wide, low-slope ranch roofs catch wind on a much broader surface than a steep gable in the foothills. The Santa Anas funnel through the San Gabriel Valley and lift the shingle edges, especially where the original starter course has aged out. We see creased shingles and lifted flashings on these homes more than on the steeper-pitch construction nearby. Call (866) 321-6172 after a wind event and we’ll check the roof before water gets in.
What you’re seeing is the difference between a roof that sheds sun and a roof that sheds water. The deck under an intact-looking shingle field can be soft from years of UV exposure plus the occasional El Niño rain. Once the underlayment and sheathing at the eaves rot, the first real rain finds its way in. We inspect the deck from inside the attic, not just from the shingle side.
We install genuine CertainTeed shingles, Flintlastic membrane, and underlayment. We are not authorized or sponsored by CertainTeed; we’re an independent service provider. That’s actually an advantage, because we’ll tell you when a CertainTeed product is the wrong fit for your roof pitch or deck condition, without any manufacturer incentive to push it. Your roof, your material choice.
