CertainTeed Roofing in South El Monte, CA | Van Nuys Roofing Co
We provide independent CertainTeed sales & service across South El Monte, from Landmark architectural shingle tear-offs to Flintlastic low-slope repairs on garage additions. What makes our CertainTeed work here different is simple: we know how these roofs age under Whittier Narrows heat, Santa Ana wind, and the permit scrutiny that comes with older unpermitted flat add-ons. If you’re weighing repair against replacement, call (866) 321-6172 for a straight read on the roof.
Why South El Monte Residents Choose Us for CertainTeed Service
CertainTeed makes a wide product line, and it behaves differently depending on what it’s installed on. A Landmark architectural shingle on a proper steep-slope pitch is a different animal than Flintlastic cap sheet laid across a flat garage conversion. South El Monte, CA has both, often on the same lot. We’ve torn off sun-brittled organic three-tab on the main house and found failing membrane on the rear addition behind it, all under one roof. That’s where our multi-brand experience pays: we know the specs, the fastening requirements, and where each product line starts to fail in this specific climate.
Rick Dominguez, our owner, learned the trade through the construction technology program at Los Angeles Valley College and spent the better part of two decades on rooftops across the San Fernando Valley before starting Van Nuys Roofing Co. His dad was a finish carpenter, so the hands-on approach was baked in early. Rick’s rule on every CertainTeed job is the same as any other brand: inspect first, recommend second. “If it doesn’t need replacing, I’m not going to tell you it does.” That’s why South El Monte homeowners call us for a second opinion before signing a full replacement quote from a single-brand shop, and why neighbors ask about CertainTeed repair in Rosemead too.
We’re an independent roofing company. Not authorized, sponsored, or warranted by CertainTeed. That means when we tell you a repair will outlast the shingle or that the shingle is done, there’s no manufacturer incentive behind the answer. Just what we saw on the roof.

Common CertainTeed Roofing Problems We Solve in South El Monte
- Brittle organic-mat three-tab shingles on 1950s-70s tract homes. The original CertainTeed XT25 and XT30 three-tab roofs in South El Monte didn’t just age. Decades of intense afternoon sun bouncing off surrounding warehouse roofs and asphalt yards baked the organic mat until it crumbled. Tear-offs on these homes come up in fragments, not shingle sheets. We handle these removals carefully because the decking underneath is often as tired as the shingle.
- Santa Ana wind damage along west-facing rakes and eaves. Wind that funnels across the Whittier Narrows hits South El Monte hard. Shingle tabs along west-facing edges lift, crease, or tear where the original fastening was marginal or the drip edge has rusted through. We see this pattern repeat on nearly every older tract roof after a strong wind event. The fix usually starts with replacing deteriorated edge metal, not just gluing tabs down.
- Ponding on flat-roofed garage conversions and rear additions. Winter storm runoff and flood-control releases from the Rio Hondo and San Gabriel channels don’t drain fast enough on flat additions with failed scuppers. Flintlastic or rolled cap sheet seams split where water sits, and the leak shows up inside long before the membrane fails outright. South El Monte has a lot of these flat add-ons, many built out during densification decades ago and never permitted.
- Premature underlayment failure on shallow-pitch sections. Some South El Monte lots had low-slope sections shingled with steep-slope Landmark product when the pitch never met the shingle’s minimum. The shingle looks fine, but the underlayment below has been taking water and the nails have backed out. We catch this during inspections more often than homeowners expect.
- Failed valleys and pipe boots on otherwise sound roofs. Not every CertainTeed problem is a full failure. When the field is still solid but a valley or boot has given out, we fix that. The honest answer on these jobs is usually a targeted repair, not a full roof replacement. We’ll tell you which one makes sense.
CertainTeed Service in South El Monte: What Local Conditions Mean for Your Equipment
South El Monte is a small, densely built working-class industrial suburb in the Whittier Narrows flood-control basin. Most roofing work here happens on closely packed mid-century tract houses and low industrial buildings, and the city hall runs a tight permit process. Here’s the part that trips up a lot of homeowners: South El Monte’s roofing permits get flagged for the older unpermitted flat add-ons and garage conversions common on these lots. A CertainTeed shingle job on the main house often stalls until the low-slope addition is brought into the permit drawing and inspected as part of the same scope. You can’t just re-shingle the main pitch and leave the flat section off the permit. The city wants to see both roofs in the drawing, and the inspector will walk both. We’ve handled enough South El Monte permits to know how to sequence the work so you’re not waiting on plan corrections after approvals, and we bring the same expertise to CertainTeed in Temple City.er the tear-off is done.
CertainTeed Models & Products We Service in South El Monte
We work across the CertainTeed line for El Monte CertainTeed service: Landmark architectural shingles, Presidential Shake and Presidential TL, Flintlastic SA modified-bitumen cap sheet for low-slope, and the older XT25 and XT30 organic three-tab that still covers a lot of South El Monte tract roofs. On repairs we use CertainTeed-branded or equivalent spec-matched shingles, underlayment, and accessory flashings so the assembly stays consistent. We keep common Landmark colors and Flintlastic repair stock moving through our local supply runs, which shortens turnaround when a partial repair needs matching. For less common colors, we source direct and tell you the lead time before we start.

AfterCertainTeed Service Pricing in South El Monte
What you’ll pay depends on what we find. A targeted CertainTeed shingle repair or flat roof patch runs a few hundred dollars when the issue is isolated. A full Landmark architectural re-roof on a smaller South El Monte ranch typically lands between $9,000 and $14,000, and a Flintlastic low-slope replacement on a garage addition or flat section usually runs $4,500 to $8,500. The big variables are decking condition, how much edge metal needs replacement, and whether the permit scope pulls in an unpermitted flat addition. Our free estimate includes a walk on the roof, written line-item pricing, and a straight answer on repair versus replacement. Call (866) 321-6172 to schedule yours.

FAQs – CertainTeed Roofing in South El Monte
Yes, South El Monte requires a building permit for re-roofing, and a flat garage addition or rear unit that was never permitted will complicate the scope. The city typically wants the low-slope section brought into the permit drawing and inspected alongside the main roof. We handle the permit process as part of the job, including the flat section, so you’re not stuck with a partial approval. Call (866) 321-6172 and we’ll tell you what your specific lot will likely need.
Because the flat roof and the shingle roof are two different systems. On South El Monte lots, the rear flat addition usually has Flintlastic or rolled cap sheet that’s older than the main shingle roof, and ponding after winter storm runoff or flood-control releases finds failed seams and scupper details before the membrane itself fails. The shingle roof can be perfectly sound while the flat section leaks. We repair these independently or together. Call (866) 321-6172 for a free inspection.
Not always. CertainTeed Landmark architectural shingles are rated for a minimum slope, and a lot of South El Monte low-slope or shallow-pitch sections fall below that line. Shingling them anyway leads to premature underlayment failure and nail pops, even when the shingle looks fine from the ground. We’ll measure the pitch during the estimate and tell you if your roof needs a low-slope product like Flintlastic instead. Call (866) 321-6172 for an exact answer on your roof.
Both, but they fail differently. Summer heat from the Whittier Narrows basin bakes shingle mats until they’re brittle, especially on older organic three-tab. Santa Ana winds then funnel across the Narrows and lift or crease the weakened tabs along west-facing rakes and eaves. It’s usually a one-two punch: heat degrades the shingle, wind finishes the edge. If you’re seeing lifted or creased tabs after a wind event, call (866) 321-6172 before the next rain finds the gaps.
Usually. We keep common CertainTeed Landmark colors stocked locally and source less common ones direct, so a valley or boot repair blends with the surrounding field. On older organic three-tab roofs, a perfect match isn’t always possible because the shingle has faded over decades, but we’ll be upfront about how close the match will be before we start. Call (866) 321-6172 and we’ll check your color during the estimate.
