GAF Construction in Van Nuys, CA

GAF Construction in Van Nuys, CA | Rowan Construction Group Sherman Oaks

We provide independent GAF roofing service across Van Nuys, from single-family ranches near Kittridge Street to soft-story apartment buildings along Van Nuys Boulevard. What sets our GAF work apart here is the permit coordination we do with seismic retrofit crews - because Van Nuys’s mandatory soft-story ordinance means roof flashing and structural shear walls often get inspected in the same cycle, and we’ve learned to build for that.

Why Van Nuys Residents Choose Us for GAF Service

We’ve installed and repaired GAF systems on hundreds of San Fernando Valley homes since 2007, and Van Nuys keeps us busy for specific reasons. The 1960s tuck-under apartments and post-WWII stucco ranches here carry Northridge-era patch jobs, original galvanized plumbing, and flat or low-slope roofs that fail on predictable patterns we’ve documented across 4,000-plus projects.

Grant Rowan, our owner, studied construction technology at Los Angeles Valley College in Valley Glen before he ever swung a framing hammer on a paid job. He’s spent the better part of three decades doing construction work across the Valley, and he stays hands-on enough to feel when a subfloor isn’t sitting right just by walking across it. That same attention shows up in our GAF estimates: we name the shingle line, state the price range, and explain why one underlayment spec makes sense for your roof deck and another doesn’t.

We stock genuine GAF shingles, underlayments, and accessories through authorized distributors. We won’t substitute generic brands on a GAF system because it voids the manufacturer’s material warranty. Our crews are background-checked and uniformed; a live person answers calls 24/7; and every visit includes a documented photo record as standard, not an upgrade. Under Clause 1 of the Haven Standard, the price is written before anyone starts.

Common GAF Construction Problems We Solve in Van Nuys

• Hypersun UV degradation on Timberline HDZ. Van Nuys summers regularly exceed 100°F, baking asphalt shingles from the top down. We see granule loss and edge curling far earlier than the coastal LA average, often at year 12 instead of year 18. The valley’s extreme thermal cycling accelerates the breakdown of the protective granule layer that GAF embeds in the HDZ mat.
• Thermal cycling racking at roof-to-wall flashings. The San Fernando Valley’s 40-degree day-night swings expand and contract wood framing under stucco, opening seams at GAF flashings and causing chronic leaks in 1960s tuck-under apartments near Sepulveda. The movement is invisible from the ground until water stains the ceiling below.
• Northridge-era deferred repair failure. Many post-1994 patch jobs on Van Nuys roofs used mismatched GAF underlayments and sealants that have now dried out. We find blistering and nail pops under Grand Sequoia installations where the original roofer layered new shingles over compromised base layers without stripping to deck.
• Soft-story retrofit collateral damage. When seismic crews open walls for retrofit work on Van Nuys Boulevard apartment buildings, they routinely expose GAF roof-to-wall flashing that was never tied into the original stucco. The opening creates immediate water intrusion paths that weren’t there before the retrofit began.
• Low-slope membrane failure on 1960s flat roofs. Van Nuys’s apartment stock includes extensive low-slope construction where GAF modified bitumen or TPO systems were retrofitted over original tar-and-gravel. The 100°F-plus heat softens the adhesive, and foot traffic from HVAC maintenance completes the separation.

GAF Service in Van Nuys: What Local Conditions Mean for Your Equipment

Van Nuys sits in the direct damage corridor of the 1994 Northridge earthquake and holds one of the San Fernando Valley’s densest concentrations of 1960s-70s soft-story tuck-under apartment buildings - the exact structural type that pancaked in that quake. Los Angeles’s mandatory soft-story retrofit ordinance (Ordinance 183893) has put thousands of these buildings on a compliance timeline, and that changes how GAF roofing work happens here in a way it simply doesn’t in Burbank or Glendale.

Because Van Nuys has this uniquely dense retrofit pipeline, our GAF roofing crews routinely coordinate roof flashings and vents with structural retrofit work in the same permit cycle. A seismic contractor opens the rear wall to install a shear panel, and suddenly a 30-year-old GAF flashing detail is exposed and failing. We replace the flashing with GAF WeatherGuard HP, tie the roof edge into the new shear wall, and schedule the LADBS inspection so the roofing and structural sign-offs happen together. The owner saves a second permit fee and avoids the delay of a failed recheck.

On a 1962 tuck-under apartment building off Van Nuys Boulevard near Kittridge Street, our crew was called after a soft-story retrofit opened the rear wall and exposed decades of failed GAF roof-to-wall flashing. We removed the blistered Timberline HDZ field, replaced the rusted flashing with GAF WeatherGuard HP and new underlayment, and tied the roof edge into the retrofit shear wall so the inspection passed without a second water intrusion. The owner avoided a full replacement and the building cleared its retrofit inspection on the first recheck.

GAF Models & Products We Service in Van Nuys

We work with the full GAF residential line and keep the most common Van Nuys repair stock on hand: Timberline HDZ for standard pitched roofs on post-WWII ranches; Timberline UHDZ where the thicker shingle profile helps with the valley’s wind exposure; Grand Sequoia for the dimensional look on owner-occupied buildings where curb appeal affects resale; and WeatherGuard HP for low-slope sections and critical flashings on apartment retrofits.

Our GAF sales & service approach is independent - we’re not a manufacturer-authorized contractor, and we don’t claim to be. We follow GAF’s published installation standards and source genuine GAF materials through authorized distributors. For Van Nuys customers, that means we can typically turn a repair around in 48-72 hours without waiting on a factory parts shipment, because we stock what fails here most often.
