CertainTeed Construction in Van Nuys, CA

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

We provide independent CertainTeed roofing and siding service across Van Nuys, from post-war stucco ranches to soft-story apartment buildings along Van Nuys Boulevard. The one thing that makes our CertainTeed work here different: we’ve learned to price for what the roof actually needs after LADBS inspectors expose hidden unpermitted framing, not just what it looks like from the street. Call (213) 221-0788 for a written estimate before any work starts.

Why Van Nuys Residents Choose Us for CertainTeed Service

We’ve installed and repaired CertainTeed systems across the San Fernando Valley since 2007, and Van Nuys keeps us busy for specific reasons. The valley’s 10-15°F temperature premium over coastal Los Angeles means asphalt shingles here work harder than the same product in Santa Monica. We’ve tracked how CertainTeed sales & service products perform through those cycles, and we know which underlayment combinations hold up when the roof deck hits 140°F in August.

Grant Rowan, our owner, grew up in Los Angeles and 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’ll tell you that Van Nuys’s housing stock - the 1940s-60s stucco ranches and the 1960s-70s tuck-under apartments - presents a specific set of conditions that generic CertainTeed installers miss. That same expertise carries over to our Kitchen Remodeling in Van Nuys work. We don’t guess at ventilation; we calculate it based on the original framing, any unpermitted additions, and the actual attic geometry. Our crews are background-checked and uniformed, and every visit produces a documented photo record as standard, not an upgrade.

We use genuine CertainTeed shingles, underlayments, and WinterGuard membranes to protect system integrity. When aftermarket flashing or fasteners outperform OEM in Valley heat, we source those too. The price is written before anyone picks up a tool. That’s Clause 1 of The Haven Standard.

Common CertainTeed Construction Problems We Solve in Van Nuys

• Accelerated granule loss on Landmark shingles. Van Nuys regularly exceeds 100°F in summer, and low-slope or poorly ventilated roofs bake. The asphalt binder softens, granules wash into gutters, and the exposed matting deteriorates faster than the warranty predicts. We see this most on south- and west-facing planes of 1970s tuck-under buildings where original soffit vents were never installed.
• Nail-head popping and seal-strip failure. The valley’s extreme thermal cycling - 40°F swings between day and night - causes wood roof decks to expand and contract. On older CertainTeed installations, this movement works nails loose and breaks the adhesive seal between shingle tabs. Wind-driven rain gets underneath, and the damage spreads from a single entry point.
• Shingle tab cracking in original wood-frame homes. Post-WWII stucco ranches in Van Nuys neighborhoods like the area near Van Nuys Airport were framed with lumber that has dried and settled over 60-70 years. The resulting movement stress cracks CertainTeed shingle tabs, especially where roof planes change angle or where additions were tied into original eaves without proper valley flashing.
• Cedar Impressions siding warping on stucco retrofits. Homeowners sometimes install CertainTeed Cedar Impressions over original stucco without adequate expansion gaps. The 40°F day-night temperature swing in Van Nuys causes the vinyl to buckle against rigid substrate. We remove the stucco or fur out properly before siding, so the product can move as designed.
• WinterGuard membrane adhesion failures. When original roof decks weren’t cleaned of Northridge-era debris, old felt, or fragmented sheathing before new underlayment went down, the adhesive doesn’t bond. Moisture gets trapped, and the membrane peels. We see this on re-roofs where the previous contractor skipped the tear-off step to save a day in July heat.

CertainTeed 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. Los Angeles’s mandatory soft-story retrofit ordinance has put thousands of these structures on a compliance timeline, and that shapes CertainTeed roofing work here in a way it wouldn’t in Burbank or Glendale.

Here’s what happens: a property owner pulls a retrofit permit through the Van Nuys LADBS satellite office, and the inspector finds unpermitted rear additions or garage conversions from the 1980s-2000s. The owner now faces mandatory legalization or demolition orders before seismic work proceeds. If the roof over that unpermitted space was CertainTeed Landmark from the early 2000s, we often get called to re-scope what looked like a simple repair. The original roof deck geometry changes once the unpermitted framing comes out. Ventilation paths disappear. Square footage shifts. We’ve learned to write our Van Nuys estimates with contingency language and a clear change-order process, because the project that starts as a 20-square re-roof can become a 35-square full replacement with new intake vents and sheathing repairs once the hidden framing is exposed. The same rigor applies to our Bathroom Remodeling - Van Nuys projects. Measure twice, write it down, then build it.

CertainTeed Models & Products We Service in Van Nuys

We work with the full CertainTeed residential roofing and siding catalog. For asphalt shingle re-roofs, we install Landmark and Landmark Pro systems, matching the color blend to existing elevations when we’re doing partial repairs. Presidential Shake luxury shingles go on higher-end Van Nuys properties where the HOA or architectural review requires thicker shadow lines. Cedar Impressions siding covers the stucco-to-vinyl conversions we see in the older ranch neighborhoods.

Under the shingles, we specify CertainTeed underlayments and WinterGuard waterproofing membranes at valleys, eaves, and penetrations. We stock common Landmark colors and WinterGuard rolls locally for fast Van Nuys turnaround, though Presidential Shake and custom Cedar Impressions orders typically run 2-3 weeks. We keep aftermarket copper and painted steel flashing in inventory - the valley’s heat degrades standard aluminum faster than the manufacturer spec suggests, and we’d rather use the better material than replace it twice.
