CertainTeed Roofing in Tujunga, CA | Moreno Valley Roof Repair
We provide independent CertainTeed roof repair and replacement across Tujunga, including both 91042 and 91043. What separates our CertainTeed work here from typical shingle service is straightforward: Tujunga sits in a Very High Fire Hazard Severity Zone, so most re-roofs require a full tear-off down to the decking, not just a shingle layover. Call (866) 217-3967 for a free estimate on your CertainTeed roof, whether it’s a Landmark tear-off or a tile underlayment job.
Why Tujunga Residents Choose Us for CertainTeed Service
Our crews work on CertainTeed roofs across the San Gabriel foothills every week, so we know how these products actually age under canyon sun and Santa Ana wind. We are an independent CertainTeed service provider, not authorized, sponsored, or endorsed by CertainTeed, and we say so plainly. That independence means we recommend what’s right for your home, not what a manufacturer program tells us to push.
Ruben Ibarra, our owner, grew up in the Sunnymead Ranch area of Moreno Valley and has spent decades watching Southern California roofs take a beating from foothill heat and wind. He picked up the trade through the construction technology program at Riverside City College, then spent years on residential and light commercial jobs before starting this company. His approach hasn’t changed since: I’ll tell you what the roof needs, not what sounds like a bigger job. For Tujunga homeowners, that means honest guidance on whether a CertainTeed repair will hold or whether the fire-zone rules require a full replacement. We also provide CertainTeed service in Sunland for nearby canyon communities.
We also carry CertainTeed sales & service expertise across our full brand roster, so you’re never locked into one product line. If CertainTeed Landmark is right for your roof, we’ll say so. If another brand fits better, we’ll tell you that too.

Common CertainTeed Roofing Problems We Solve in Tujunga
- Sun-cooked, granule-scoured field shingles. Tujunga’s south and west roof planes face direct San Gabriel foothill sun all afternoon. CertainTeed shingles on those exposures lose granules and start curling years before the shaded north plane shows wear. We see this pattern constantly. The fix is usually a plane-specific replacement rather than a full roof, and we’ll tell you which is actually warranted.
- Wind-lifted and torn tabs after Santa Ana gusts. When canyon winds rake through Tujunga, shingle tabs and ridge caps tear where the original install used four-nail fastening. CertainTeed’s own installation specs call for six nails in high-wind zones, and we re-secure or replace those sections with the proper fastener count.
- Old CertainTeed three-tab layovers on top of original wood shingles. Tujunga has plenty of 1940s and 1950s ranch homes where somebody shingled over wood shingles decades ago. The wood is still under there. Fire-zone code says it all has to come off. This is a tear-off job, not a patch job, and we’ll walk you through exactly why before we touch anything.
- Flashing and valley failures on low-pitch additions. Many Tujunga homes have flat or low-slope sections over back additions. When winter rain and debris flow off the mountains, dried-out sealant and rusted valley metal let water in at exactly those transitions. We replace the flashing and the affected CertainTeed underlayment rather than just smearing more sealant over the problem.
- Tile underlayment breakdown under clay and concrete tile. CertainTeed’s tile underlayment systems sit beneath a lot of Tujunga’s tile roofs. After enough UV exposure and thermal cycling, the underlayment degrades and the tile itself is fine. We lift, replace the underlayment, and reset the tile rather than selling you a new roof you don’t need.
CertainTeed Service in Tujunga: What Local Conditions Mean for Your Roof
Here’s the thing most contractors from outside the canyon don’t fully grasp: Tujunga sits in a Very High Fire Hazard Severity Zone, which means a re-roof here is a different job than it is a few miles away. That 1940s ranch off Mount Gleason Avenue in 91042 still has its original wood shingles nailed to skip sheathing under two later layers of CertainTeed three-tab. The wood looks fine when you peek in the attic. But it’s a fire hazard, and current WUI code requires full removal down to the deck, not another layover. On one of those homes, our crew pulled back two CertainTeed three-tab layovers and found exactly that: original wood shingles still nailed to skip sheathing. All of it had to come off. We redecked with solid sheathing, added ember-resistant venting, and installed CertainTeed Landmark architectural shingles in a Class A assembly, six-nailed for canyon wind. That’s the Tujunga-specific reality. Neighboring Sunland and Glendale addresses don’t face the same requirement with the same force, which is why Tujunga homeowners need a roofer who knows the fire-zone code before the tear-off starts.

CertainTeed Models & Products We Service in Tujunga
We work on the full CertainTeed lineup you’re likely to find on Tujunga roofs, and we bring that same expertise to CertainTeed in La Crescenta-Montrose. That includes Landmark and Landmark Pro architectural shingles, Presidential and Presidential TL luxury shingles on higher-end homes, and older XT 25 and Xact three-tab shingles on re-roofs from decades past. We also handle CertainTeed tile underlayment systems beneath clay and concrete tile.
Our parts approach depends on the roof. Where the existing assembly is sound, we match CertainTeed-brand shingles and accessories to what’s already on the roof so the repair blends in. Where the decking is soft or skipped, we don’t fasten new shingles to it. On Tujunga’s older homes, the honest answer is often a full tear-off and redeck rather than a patch-and-cover. We stock common CertainTeed materials locally for fast turnaround, and anything unusual we order direct. That local inventory also supports our CertainTeed service in Shadow Hills.

AfterCertainTeed Service Pricing in Tujunga
Most CertainTeed repairs in Tujunga run between $350 and $1,800 depending on what’s damaged and where it’s located on the roof. A full CertainTeed Landmark tear-off and replacement on a typical ranch home falls between $14,000 and $28,000. Add decking replacement where the old skip sheathing or soft boards need to come out, and that adds roughly $3 to $5 per square foot. The big driver in Tujunga is the fire-zone tear-off itself: if wood shingles are buried under your existing layers, they don’t just add cost, they change the entire scope of the job. A free estimate tells you exactly what your roof needs and what it will cost, with no obligation. Call (866) 217-3967 to schedule one.

FAQs – CertainTeed Roofing in Tujunga
The old wood shingles under my Tujunga roof look fine – can we just shingle over them with CertainTeed Landmark to save money?
No. Tujunga is in a Very High Fire Hazard Severity Zone, and current WUI code requires full removal of combustible wood shingles down to the deck before a new roof goes on. Layering over them isn’t just a code violation, it’s a fire risk. We’d do a full tear-off, redeck where needed, and install a Class A assembly. Call (866) 217-3967 for a free estimate.
Will CertainTeed Landmark shingles hold up to Santa Ana winds coming off the San Gabriel Mountains?
Yes, when installed correctly. CertainTeed Landmark shingles are rated for high-wind zones, but the rating only holds if they’re six-nailed and the starter course and ridge caps are secured properly. We see wind-related failures in Tujunga most often where the original install used four nails. We always install to the six-nail spec on canyon-facing planes.
My flat addition over the back of the house keeps staining the ceiling after winter rain. Is that a CertainTeed problem?
Probably not the shingles. On Tujunga homes with low-pitch or flat addition sections, water intrusion usually comes from failed flashing at the transition between the sloped roof and the flat section, or from dried-out sealant and rusted valley metal. We fix the flashing and underlayment, not replace the whole CertainTeed roof, unless the decking underneath tells us otherwise.
Can you match the CertainTeed shingle already on part of my roof instead of replacing the whole thing?
Often yes. If the existing CertainTeed shingles are still available and the assembly underneath is sound, we can match the color and profile for a plane-specific repair. On older three-tab lines that have been discontinued, we’ll show you the closest available match and be straight about how visible the difference will be.
Do you handle the decking when the tear-off exposes soft boards or skip sheathing?
Yes. In Tujunga, almost every tear-off on a 1940s to 1960s ranch exposes either skip sheathing, soft plywood, or both. We don’t fasten new CertainTeed shingles to that. We replace or overlay the decking to meet current code before the new roof goes on, and we’ll show you exactly what we found before we proceed. Call (866) 217-3967 for details on your specific roof.
