CertainTeed Roofing in Van Nuys, CA | Weathervane Roof Repair
We provide independent Roof Repair – Van Nuys and CertainTeed service across the area, from tear-offs on 1950s ranch tracts to flat-roof additions off Van Nuys Blvd. Most CertainTeed roofs here fail from UV-brittled shingles and Santa Ana wind lift, not rain rot, which shapes how we diagnose and repair them. If you’re seeing granule loss, curling tabs, or leaks at valleys, call us at (877) 755-4274 for a straight assessment. We’ll tell you whether the roof needs a patch, a partial replacement, or the full tear-off.

Why Van Nuys Residents Choose Us for CertainTeed Service
We’ve torn off and re-roofed hundreds of CertainTeed installations across the San Fernando Valley. We know how Landmark architectural shingles and XT 3-tabs behave after 15 or 20 summers of Valley heat, and we know what the decking underneath usually looks like on a 91405 ranch that’s been carrying three layers since Eisenhower was in office. Gil Tanner, our owner, grew up in the Montrose area and learned roofing the old way: working alongside experienced crews on everything from flat torch-down decks to clay tile on Spanish Revival homes in the foothills. Two decades of that work taught him to read a roof before recommending anything. We don’t carry manufacturer authorization, and we’ll say that plainly. What we carry is hands-on CertainTeed experience and the willingness to tell you a repair will hold when a salesperson would push a $15,000 replacement. Our CertainTeed sales & service work draws on that repair-first judgment, not a vendor badge.

Common CertainTeed Roofing Problems We Solve in Van Nuys
- UV-brittled asphalt on Landmark and XT shingles. Van Nuys summers routinely climb past 100°F, and that heat bakes the volatile oils out of CertainTeed asphalt faster than coastal LA ever sees. Granules wash off, the fiberglass mat dries and curls, and shingles crack when stepped on. We see this most on original first-over composition roofs from the 1990s that have hit the 20-year mark.
- Wind-lifted and creased tabs after Santa Ana events. CertainTeed 3-tab and architectural shingles that sealed lightly, or were installed on shallow-pitch decks, peel at the rake and ridge when the winds come down through the Valley. Once the seal strip breaks, tabs flap and tear. We find this after nearly every strong Santa Ana season, especially on the 1947 – 1965 ranch homes with low-slope gables.
- Adhesive seal-strip failure on older Landmark shingles. After 15 to 20 dry years, CertainTeed’s factory seal strip turns powdery. The roof looks fine from the ground, but a moderate gust lifts tabs that should be stuck. We check seal integrity during every Van Nuys inspection because this failure hides in plain sight.
- Underlayment degradation on low-slope assemblies. On shallow-gable homes and flat-roof additions common in Van Nuys, Flintlastic SA and felt underlayments dry out and wrinkle under sustained heat. Leaks show up at valleys and vent penetrations before the shingle surface looks worn, which is why we don’t diagnose from the curb.
- Layered tear-off complexity on original shake roofs. Many Van Nuys ranch homes still carry original wood shake under one or two composition layers. You can’t simply overlay that again. The weight, trapped heat, and fire vulnerability all argue for a full tear-off and re-deck before new CertainTeed shingles go on.
CertainTeed Service in Van Nuys: What Local Conditions Mean for Your Equipment
Here’s the thing about Van Nuys that gets missed on generic roofing pages: the 1950s ranch tracts across 91405 and 91406 were built fast and cheap during the postwar boom, which means shallow-pitch roofs originally covered in wood shake, not plywood-ready decks for modern shingles. Many of those homes now carry two or three layers, original shake at the bottom with first-over composition on top. A CertainTeed re-roof in this city usually means pulling all of it down to the skip sheathing, replacing rotted boards, and re-decking before the new Landmark or Presidential Shake goes on, unlike CertainTeed repair in Encino where conditions differ. That’s not how it works in newer Valley neighborhoods or up in the hills. Layering another roof over three existing layers traps heat against the deck, adds dead load the original framing wasn’t sized for, and in a brush-fire zone like the north Valley, it leaves the fire-vulnerable shake in place under a thin veneer. We spec Class A fire-rated CertainTeed assemblies to replace what was never fire-rated in the first place. That’s the Van Nuys reality: this city’s roofing work is tear-off work.
CertainTeed Models & Products We Service in Van Nuys
We work on the full CertainTeed shingle lineup you’re likely to find in Van Nuys: Landmark architectural shingles, XT 25 and XT 30 3-tabs, Presidential Shake luxury profiles, and Flintlastic SA self-adhered underlayment. When a repair or partial replacement needs to tie into existing courses, we match the profile rather than slapping on whatever’s on the truck. That means Landmark color and exposure matched to the existing field, or the correct Flintlastic underlayment for low-slope and flat sections. For isolated damage on an aging roof, we’ll tell you straight whether a patch will hold another season or whether the whole field is too brittle to touch. On 60-year-old shake or first-over composition decks, the honest answer is usually a full tear-off and re-deck. We stock common CertainTeed profiles for Van Nuys jobs, which keeps turnaround tight when you need a section replaced before the next wind event.

Sherman Oaks CertainTeed service and Van Nuys work are both driven by a few local factors: how many layers need to come off, whether the decking survived beneath them, and which profile you’re matching. A minor Landmark repair that doesn’t require a tear-off sits at the low end of the range. A full re-roof with tear-off, re-decking, Flintlastic SA underlayment, and Class A fire-rated Landmark shingles lands higher, and that’s before we get into fascia repair or cracked 1x deck boards that only show up once the old roof is gone. Your free estimate includes a roof inspection first so the number reflects what’s actually up there, not a worst-case guess. Call (877) 755-4274 and we’ll walk the roof with you before quoting.

FAQs – CertainTeed Roofing in Van Nuys
No, and any roofer who says yes is doing you a disservice. The original shake is fire-vulnerable, the framing wasn’t sized for another layer, and trapping that much heat under new shingles shortens their life. We recommend a full tear-off to the skip sheathing, re-deck where needed, then Class A fire-rated CertainTeed Landmark over Flintlastic SA. Call (877) 755-4274 for a free estimate on the full tear-off and re-roof.
That dry heat is exactly the problem. Van Nuys summers over 100°F bake the volatile oils out of asphalt shingles much faster than coastal moisture would. Landmark and XT shingles that hit 15 to 20 years in this climate often show curling, cracking, and bare fiberglass mat. It’s UV degradation, not a manufacturing flaw. Whether it warrants repair or replacement depends on how widespread the damage is. Call (877) 755-4274 and we’ll tell you what we see on the roof, not what a script says to say.
Usually a repair, but it depends on the roof’s age and condition. Lifted and creased tabs can often be re-sealed with the right adhesive, especially if the seal strip is still intact. But if the tabs are brittle from UV exposure, walking the roof to fix them can crack dozens more. We’ll check the seal strips and shingle flexibility before recommending anything. Get in touch at (877) 755-4274 for an honest read.
The underlayment usually fails before the shingles do. On low-slope and flat sections, Flintlastic SA or felt underlayment dries out and wrinkles under Valley heat, and water finds its way in at valleys and penetrations even when the shingle surface looks fine. We pull the valley flashing, replace the underlayment, and re-set the transition properly. Patching the shingles without fixing the underlayment is a one-season fix. Call (877) 755-4274 for a diagnosis.
Yes, Van Nuys requires permits for full re-roofs, and the fire rating matters more here than in most of LA. The north Valley’s brush-fire exposure means the city and your insurer both care whether the new roof is Class A fire-rated. We handle the permitting and spec Class A CertainTeed assemblies as standard on replacement work. Estimates are free: (877) 755-4274.
