Why Glen Avon Residents Choose Us for CertainTeed Service

We’ve torn off enough original wood-shake roofs in Glen Avon to know what’s underneath before we even set the ladder. Most of these 1950s and 1960s tract homes were built with lightweight skip sheathing, and after 50-plus years of drying heat, that decking is often too far gone to carry new shingles. We inspect first and tell you what’s actually under the old roof, because nobody wants a fresh CertainTeed Landmark roof nailed to rotten wood.

Rick Dominguez runs our crew, and he grew up off Sepulveda Boulevard near the old Van Nuys Municipal Airport. He learned roofing through the construction technology program at Los Angeles Valley College and has spent two decades on rooftops across the inland valleys, including plenty of Glen Avon homes. His approach is simple: if it doesn’t need replacing, he’s not going to tell you it does. That’s why we’re comfortable handing you a standalone inspection before any work gets quoted.

Common CertainTeed Roofing Problems We Solve in Glen Avon

• Original wood-shake roofs that have gone brittle. These shakes dry out under Glen Avon’s intense summer heat and low humidity until they crumble in your hand or split right at the nail line. By the time homeowners call us, the roof is often closer to kindling than structure. Re-roofing with a CertainTeed Landmark system in a Class A assembly is the most common fix we perform in the older tracts.
• Granule loss on south and west-facing slopes. Asphalt shingles on these exposures take the full brunt of the afternoon sun and go through brutal thermal cycling every single day. This thermal cycling causes shingles to become brittle and shed granules years before the north slope shows any wear. If one slope looks thin and the other looks new, the issue is usually thermal breakdown, not a bad shingle batch.
• Skip sheathing that can’t hold a new roof. Homes off Mission Blvd and Limonite Ave were often built with spaced boards instead of solid plywood or OSB. When we tear off old shake, we frequently find decking that’s cracked, warped, or too gapped to support CertainTeed shingles. We replace it with solid decking before any underlayment goes down.
• Flashing and vent boot failures ahead of the shingle field. Many Glen Avon homes have low-pitch mid-century rooflines, and water loves to track back under the courses at penetrations. The first winter rain after years of dry weather often reveals the flashing was the weak point all along, not the shingles. We fix the penetration properly and then address the surrounding CertainTeed field only if it actually needs it.
• Underlayment breakdown on low-slope sections. CertainTeed Flintlastic modified bitumen performs well on low-slope roof areas, but if the original felt or underlayment underneath has degraded from decades of heat, the system fails from below. We replace the full substrate and install fresh Flintlastic so the repair actually holds through the next Santa Ana season.

CertainTeed Service in Glen Avon: What Local Conditions Mean for Your Equipment

Here’s the detail that changes almost every CertainTeed re-roof in Glen Avon and that you won’t hear from a generic roofer: the older tracts off Mission Blvd and Limonite Ave were built with lightweight skip sheathing under original wood shake, which means a re-roof here is rarely just a shingle swap. The fire-rated assembly, meaning solid decking plus Class A underlayment plus the shingle itself, is what your insurer and the ember exposure from Santa Ana wind events actually care about.

When we pull up a 1960s original shake roof in Glen Avon, we almost always find the skip sheathing has gaps wide enough that wind-driven embers could reach the attic. That’s a fire-risk problem no shingle alone can solve. CertainTeed Landmark architectural shingles carry a Class A fire rating when installed on solid decking with the right underlayment, but that rating only matters if the whole assembly is done correctly. We add CertainTeed WinterGuard underlayment and solid decking before the first shingle goes down. That’s the difference between a roof that looks new and a roof that actually protects the house during a wind event.

CertainTeed Models & Products We Service in Glen Avon

We work on the CertainTeed product lines that show up most often in Glen Avon: Landmark architectural shingles, Presidential Shake and Presidential TL, Flintlastic modified bitumen for low-slope sections, and WinterGuard water-resistant underlayment. We install genuine CertainTeed materials because the fire rating and the manufacturer warranty depend on a complete, matched system, not a mix-and-match patch job. Where the decking or flashing is the real problem, we say so plainly. Patching a sound CertainTeed field over rotten sheathing just moves the failure down a layer and costs you more down the road.

For Glen Avon homes, we stock CertainTeed Landmark shingles and matching accessories for fast turnaround on replacements, and we order specific colors or Presidential lines ahead of your scheduled tear-off so there’s no delay once we’re on the roof. Our crew works across seven major roofing brands – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – so when we recommend CertainTeed for your Glen Avon home, it’s because the material fits your roof and budget, not because we’re locked into one manufacturer. That’s the point of doing CertainTeed sales & service the way we do.

FAQs – CertainTeed Roofing in Glen Avon

My Glen Avon house still has its original wood-shake roof – can you just put CertainTeed shingles over it?

No. We don’t install new shingles over original wood shake, especially in Glen Avon where 50-plus years of heat have left the shakes brittle and the skip sheathing beneath them unreliable. The old roof has to come off, the decking gets inspected and usually replaced, and then we set the CertainTeed system on a solid, fire-rated base. Anything less won’t pass inspection and won’t protect your house. Call (866) 321-6172 for a free assessment of what your roof actually needs.

Will a Class A CertainTeed roof actually help with insurance in 92509?

Yes. A properly installed Class A fire-rated assembly using CertainTeed Landmark shingles on solid decking with WinterGuard underlayment meets the standard insurers look for in wildfire-conscious areas like Glen Avon. The key word is assembly, because a shingle alone doesn’t earn the rating. We bring the decking and underlayment up to spec as part of the re-roof. Call (866) 321-6172 and we’ll walk you through what your specific roof needs for compliance.

Why do my CertainTeed shingles look worn on one side of the roof and fine on the other?

In Glen Avon, that’s almost always thermal cycling. South and west-facing slopes bake under 100°F summer sun and cool rapidly at night, which brittles shingles and strips granules years before the shaded north slope shows any age. It’s not a defect in the shingle; it’s the exposure doing what exposure does. If one slope is shot and the other is sound, we can often replace just the affected plane rather than the whole roof. Call (866) 321-6172 for a free inspection and an honest read on what needs replacing.

How does the dry Glen Avon heat affect a CertainTeed Landmark roof over time?

The heat accelerates two things: thermal expansion and contraction cycles on the shingle surface, and drying of any wood components underneath. Landmark shingles hold up well, but the substrate matters just as much. That’s why we focus on what’s under the shingles when we inspect a Glen Avon roof. A Landmark roof on solid decking with proper underlayment will outlast one nailed over tired wood. Call (866) 321-6172 for an exact quote on your CertainTeed replacement, and estimates are free.

Can my old wood-shake roof really be a fire risk during Santa Ana winds?

Yes, and it’s not theoretical. After decades of inland heat and dry spells, old wood shake in Glen Avon dries out until it’s essentially kindling. During Santa Ana wind events, wind-driven embers can land on that dried shake and ignite it, endangering the whole house. Replacing it with a Class A CertainTeed assembly removes that risk. If your roof is still original shake, call (866) 321-6172 for a free estimate, and we’ll tell you exactly what a fire-rated replacement involves.
