CertainTeed Roofing in Van Nuys, CA | Tilecraft Roofing
We service CertainTeed roofs throughout Van Nuys as an independent contractor, not a manufacturer affiliate. The thing that sets our CertainTeed work here apart is simple: Van Nuys is a flat-roof town, and most of the CertainTeed failures we see aren’t shingle failures. They’re Flintlastic membranes, underlayments, and flashing that have baked through years of 100-degree Valley heat. Call (833) 467-4846 and we’ll tell you honestly whether your CertainTeed roof needs repair or replacement.
Why Van Nuys Residents Choose Us for CertainTeed Service
We know CertainTeed’s product lines the way a mechanic knows a specific engine. Landmark shingles, Flintlastic membrane, Xtreme WeatherGuard underlayment, Presidential Shake: we’ve installed, repaired, and torn off all of them across Van Nuys, and we know where each one fails under Valley conditions. When we quote a repair, we’re not guessing at the assembly beneath the surface. We know what’s under the tile on a 1950s ranch home here because we’ve opened those roofs before.
Ruben Castellano grew up a few blocks from Hollydale Regional Park and learned construction technology at East Los Angeles College before spending years on residential and commercial roofs across the Southeast LA corridor. That background means we approach every Van Nuys roof the same way: look carefully, diagnose honestly, and recommend the repair or replacement that actually fits the roof’s condition. We’re an independent Sherman Oaks CertainTeed service provider, which means we’re not obligated to push a new roof when a targeted fix will hold. The roof either does its job or it doesn’t. Let’s make sure it does.

Common CertainTeed Roofing Problems We Solve in Van Nuys
- Blistered and alligatored Flintlastic membrane – Van Nuys summers push temperatures above 100°F, and the modified bitumen on flat and low-slope roofs here expands and contracts through brutal thermal cycles. After enough heat, the membrane blisters and the surface cracks into what looks like alligator skin. The first winter rain then finds every seam and penetration that looked fine in October. We strip the failed membrane and rebuild the Flintlastic assembly properly.
- Brittle underlayment beneath tile roofs – Xtreme WeatherGuard and similar CertainTeed underlayments bake under years of Valley UV and dry out to the point of cracking. The concrete tile above can look perfectly fine while the felt layer beneath has lost its waterproofing. We see this constantly on older Van Nuys homes where tile was installed decades ago and never touched since.
- Landmark shingle granule loss on hot exposures – On west- and south-facing roof planes in Van Nuys, Landmark shingle tabs take the full force of the afternoon sun and lose sealant adhesion faster than shaded slopes. Granules wash off first, then tabs start to lift. It shows up on the sunny side long before the rest of the roof shows wear, and it’s a sign the shingles are nearing the end of their service life on those exposures.
- Failed decking under old membrane roofs – The original 1940s and 1960s low-slope roofs in Van Nuys often have wood decking that’s dried, checked, and loosened after seventy years of heat cycles. We open these roofs and find the CertainTeed membrane itself wasn’t the first failure point, the deck beneath it was. Loose decking pulls laps apart and turns a simple seam patch into a deck repair.
- Leaks at vent and duct penetrations – On flat roofs along Van Nuys Boulevard and the surrounding streets, the flashing collars around vents, ducts, and pipe penetrations fail from UV embrittlement. The membrane field can be sound while every penetration leaks. We rebuild these collars with new flashing and seal them to the membrane system so they hold through the next rain season.
CertainTeed Service in Van Nuys: What Local Conditions Mean for Your Roof
Here’s a fact that shapes our CertainTeed work in Van Nuys every week: this city sits in the San Fernando Valley, where summer highs routinely exceed 100°F and the sun beats down year-round. Roofs here bake, dry out, and fail from heat and UV far faster than roofs just over the hill on the cooler, foggier LA basin side. After a heat wave, the flat and low-slope roofs on older apartment buildings along Van Nuys Boulevard and the side streets develop blisters and alligatoring on modified bitumen. The first rain of the season is when leaks suddenly appear at seams and penetrations that looked fine in dry weather. That’s not a generic roofing problem. That’s a Van Nuys roofing problem, and it’s the reason we recommend CertainTeed Flintlastic assemblies with proper UV-stable surfacing and penetration detailing rather than the light-spec membrane work that fails after two or three Valley summers — experience we’ve also applied to our CertainTeed service in North Hills.rs.

AfterCertainTeed Service Pricing in Van Nuys
What drives cost on a CertainTeed roof in Van Nuys is the condition of what’s beneath the surface. A simple membrane patch on a sound Flintlastic roof can run $500 – $900. Replacing a fully alligatored membrane on a typical flat roof starts around $8 – $12 per square foot, and if the original wood deck underneath has checked and loosened, that adds deck repair to the scope. Tile underlayment replacement under existing tile runs $4 – $7 per square foot depending on access and deck condition. Our free estimate includes the full inspection: we look at the membrane or shingle field, the flashing, and the deck underside before we quote. Call (833) 467-4846 for an exact number on your roof.

FAQs – CertainTeed Roofing in Van Nuys
CertainTeed makes a full line of flat-roof products, and Flintlastic modified bitumen membrane is one of the most common roofing systems on Van Nuys apartment buildings and low-slope ranch homes. The brand is better known for Landmark shingles, but their flat-roof products are widely used throughout the Valley. Our CertainTeed work in Van Nuys is split fairly evenly between pitched shingle roofs and flat membrane roofs, because the city’s housing stock includes both. Call (833) 467-4846 and we’ll tell you what system your roof is carrying.
The short answer is thermal movement. Van Nuys heat cycles cause the membrane to expand and contract, and after a summer of temperatures above 100°F, seams and penetration flashings that looked intact in August can open up enough to admit water in January. Blisters and alligatoring also create entry points that only reveal themselves under actual rain load. If you’re seeing leaks only in winter, the membrane likely needs repair or replacement before the next heat wave accelerates the damage. Call (833) 467-4846 for a free inspection and we’ll pinpoint the entry points.
Yes, and this is a common job for us in Van Nuys. The original underlayment on homes built in the 1940s through 1960s has typically outlived its service life, even though the concrete tile above still has decades left. We lift the tile, remove the old felt or Xtreme WeatherGuard, inspect and repair the decking, install new underlayment, and reset the tile. The tile itself usually goes back on unchanged. Call (833) 467-4846 and we’ll assess whether your tile is a candidate for re-use.
Granule loss on the hot exposures, the south- and west-facing slopes in Van Nuys, is a predictable aging pattern for Landmark shingles in Valley heat. The sealant that holds the tabs down dries out under sustained UV, and once tabs lift, granules wash off at an accelerated rate. It’s not a defect; it’s heat-driven wear. The question is how far it has progressed. If granule loss is light and tabs are still sealed, the shingles may have years left. If you can see the fiberglass mat showing through, or if tabs are curling, you’re looking at replacement on those slopes. Call (833) 467-4846 for a straight assessment.
Yes, and we do it frequently in Van Nuys, where ranch additions often combine a low-slope section with a pitched main roof. We’d put Flintlastic membrane on the flat section and Landmark or Presidential shingles on the pitched section, with the transition flashed so both systems tie together cleanly. The flat section gets the heat-resistant membrane it needs; the pitched section gets the shingle it needs. One roof, two assemblies, both CertainTeed. Call (833) 467-4846 for a quote on the whole assembly.
