CertainTeed Roofing in North Hollywood, CA

CertainTeed Roofing in North Hollywood, CA | Marquis Roof Repair

We provide independent CertainTeed roofing service across North Hollywood, from tile underlayment replacement on 1920s Spanish bungalows to architectural shingle work on post-war tract homes. What makes our CertainTeed work different here is simple: we see the exact failure mode that defines this city, the underlayment that dies under intact tile on south-facing slopes, almost weekly. If you need a straight diagnosis and a repair that holds, call us at (866) 705-2978. We’ll tell you whether your roof needs a patch or a re-roof, and we won’t recommend the bigger job unless it’s actually warranted.

Why North Hollywood Residents Choose Us for CertainTeed Service

Most roofing companies in the Valley carry one or two manufacturer lines. We carry seven: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That matters in North Hollywood because the housing stock swings wildly from block to block. A 1930s clay-tile Spanish on one street and a 1960s flat-roof tract house on the next demand different materials and different approaches. Ron Thibodeau grew up in nearby Burbank and studied building construction at Los Angeles Valley College before spending two-plus decades roofing across the San Fernando Valley, so he’s seen what this specific climate does to CertainTeed products over time. He’s the kind of roofer who finds the actual source of a leak, not just the visible symptom. A roof done right the first time is the only version worth doing.

We’re an independent contractor, not a CertainTeed-authorized dealer or partner. That means we can recommend the right CertainTeed product for your roof without any pressure to move a specific line. It also means our repair advice is driven by what your house and this climate actually require.

Common CertainTeed Roofing Problems We Solve in North Hollywood

• Heat-fractured tile underlayment under intact clay tile. On North Hollywood’s 1920s to 1940s Spanish and Mediterranean homes, the south-facing slope gets hammered by San Fernando Valley summers that routinely top 100°F. The CertainTeed-style underlayment underneath the barrel tile dries out, cracks, and eventually turns brittle while the tile above still looks perfect. The leak shows up on your ceiling, not on your roof.
• Blistered and cracked architectural shingles on sun-exposed slopes. Landmark and Presidential architectural shingles on post-war tract houses in 91605 and 91606 lose oils from the mat after enough heat exposure. South and west-facing slopes show blistering and cracking years before the shingle face looks worn. By the time you see granule loss, the mat is often already compromised.
• Low-slope failures over enclosed porches and additions. Those original shallow-pitch roofs over enclosed porches on Valley Village bungalows were frequently shingled low-slope with architectural stock, and they fail at the eave and valley flashing first. The shingle itself may be fine; the transition details are what give out.
• Flat-roof membrane cracking at seams and penetrations. Flat-roofed garages and additions that used CertainTeed self-adhered underlayment as a low-slope membrane crack at the seams and around pipe penetrations when winter rain ponds on a dried-out sheet. A summer of heat followed by a heavy rain is when these roofs announce themselves.
• Flashing failures at tile-to-shingle transitions. North Hollywood’s mix of additions and remodels means many homes have tile on the main roof and shingles on the addition. The transition flashing between those two systems, where heat expansion cycles work the metal back and forth, is a classic leak point that gets missed on quick inspections.

CertainTeed Service in North Hollywood: What Local Conditions Mean for Your Roof

Here’s the thing about North Hollywood that doesn’t show up on a generic roofing website: the city’s older housing was built with shallow-pitch roofs over enclosed porches and additions, and those slopes are not the same pitch as the main roof. They’re flatter. Sometimes barely over code minimum. On a 1930s bungalow in the NoHo arts district or Valley Village, the main roof might be a respectable 4:12 with clay tile, but the porch addition off the back is a 2:12 with architectural shingles that have no business on that pitch in this climate. The San Fernando Valley sun cooks those low slopes relentlessly, and the CertainTeed underlayment beneath them fails years before the shingle face wears. We inspect those transitions specifically, because that’s where the first leak appears on nearly every older North Hollywood home we walk. It’s not glamorous work, but it’s the difference between a leak that stops and a stain that keeps coming back every winter. Ron learned this pattern the hard way after years of tracing ceiling stains back to porch additions, not main roofs.

CertainTeed Models & Products We Service in North Hollywood

We work with the full CertainTeed steep-slope lineup. Landmark architectural shingles, including Landmark Pro and Landmark IR, are what we install most on North Hollywood tract houses. Presidential Shake and Presidential TL cover the luxury end. CertainTeed clay and concrete tile accessory systems, including tile underlayment, battens, and flashings, are what we use when resetting tile on the older Spanish stock. And XT/AS and RoofRunner self-adhered underlayments go under tile and into valleys.

On the parts side, we use genuine CertainTeed components where the system’s warranty and profile depend on it: underlayments, starter, ridge, and matching accessory flashings. Elsewhere, quality aftermarket tile and metal flashings do the job without paying for a logo. We stock the standard CertainTeed underlayment rolls locally so North Hollywood tile resets don’t wait on a distributor’s truck.

FAQs – CertainTeed Roofing in North Hollywood

My clay tiles look fine but the ceiling stains after rain – what’s failing on my North Hollywood bungalow?

The underlayment beneath your tile has almost certainly dried out and fractured from valley heat exposure, especially on south-facing slopes. The tiles are still intact, but the waterproof layer beneath them is gone. We see this constantly on 1920s and 1930s Spanish homes across NoHo and Valley Village. The fix is tile underlayment replacement with the existing tiles reset, not a full tear-off. Call (866) 705-2978 for a free inspection and we’ll confirm it before you spend anything.

Is a CertainTeed architectural shingle right for a low-slope porch addition on a 1940s NoHo house?

Almost never at the original porch pitch. Most enclosed porch additions on 1940s North Hollywood homes sit at a 2:12 or 3:12 slope, and architectural shingles are not rated for that pitch. The correct fix is a self-adhered CertainTeed membrane designed for low-slope applications, often applied before a decorative top layer. We’ll check the actual pitch and tell you what will hold. Call (866) 705-2978 for a straight answer.

Do you replace tile underlayment without tearing off the tile on Valley Village Spanish homes?

Yes, that’s the standard approach when the tile is sound. We lift and reset the existing clay or concrete tile, replace the failed underlayment with CertainTeed self-adhered membrane, re-flash the transitions, and reset the tile. Most Valley Village Spanish homes from the 1930s and 1940s have tile that’s still perfectly good. The underlayment is what dies. A field vignette: one Valley Village homeowner on a 1930s Spanish bungalow had a ceiling stain that only appeared after winter rain. Our crew found the south-facing tile slope had cooked its original underlayment to a brittle sheet while the tiles themselves were sound. We lifted and reset the clay tile, replaced the failed underlayment, and re-flashed the porch addition. No tear-off, and the leak stopped without disturbing the original barrel tile.

My flat-roofed garage in 91605 ponds water every winter – can it just be patched?

Sometimes, but only if the ponding is shallow and the membrane hasn’t cracked at the seams. Flat-roofed garages in 91605 and 91606 often have CertainTeed self-adhered underlayment installed as the primary membrane, and once it dries out from valley heat, winter ponding splits it open. A patch can buy a few years if the membrane still has some flexibility. If it’s brittle throughout, patching is throwing money away. Call (866) 705-2978 and we’ll tell you which situation you have.

No. Marquis Roof Repair is an independent roofing contractor. We install and service CertainTeed products regularly, and we know their failure modes as well as anyone in North Hollywood, but we are not authorized, partnered, or endorsed by CertainTeed. What that means for you: our recommendations are driven by your roof, climate, and budget, not by a manufacturer relationship. We’ll tell you when CertainTeed is the right call and when another of our seven brands fits better.
