Fast, Reliable Roof Replacement Across Van Nuys
Roof replacement in Van Nuys typically runs $8,500 to $16,500 for a standard single-story ranch home, with the final number driven by square count, decking condition, and how many separate structures sit on your lot. Most Van Nuys replacements take two to four working days once materials are on site. The work we do here is different from coastal Los Angeles or the Westside, and it’s different from the high desert too. Van Nuys roofs die from sun, not storms.
Gable Roof Repair has torn off and rebuilt roofs across the 91405, 91406, 91401, and 91411 grids long enough to know what hides under the shingles on a 1950s tract home. If you’re seeing granule loss in your gutters, cracked shingle edges, or water staining at the eaves after a winter rain, call (866) 650-8319 for a roof inspection and an honest replacement estimate. We’ll tell you what actually needs doing, not what pads a quote.
Why Gable Roof Repair Is Van Nuys’s Preferred Roof Replacement Company
We work with seven major shingle manufacturers of the seven, GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and our crews are certified on each one’s installation requirements. That matters in Van Nuys because a lot of tract homes here were originally built with whatever the developer could get cheap in 1955, and the replacement you choose in 2026 shouldn’t be dictated by what one brand rep happens to push. We match the material to your roof’s pitch, your budget, and what the Valley sun will do to it over the next two decades.
Our inspection service is standalone. You get a written condition report and a straight answer before anybody quotes you a replacement. Neil Drummond built the company around that sequence: inspection first, recommendation second. If your roof has five more years in it, we’ll say so. If the decking is heat-cooked and the fascia is rotting under the eaves, we’ll show you photos and walk you through what that means. No pressure, no binder of glossy brochures. Just a local roofer who knows Van Nuys housing stock and can explain your roof in plain terms.
Styles & brands we work with
New Roof Installation in Van Nuys
New Roof Installation in Van Nuys means a full tear-off down to the decking, replacement of any damaged sheathing, new underlayment, new flashing at all penetrations, and the shingle system of your choice over the top. On the postwar ranch homes that dominate the 91405 and 91406 grids, this almost always includes work at the eaves, because the wide 1940s and 50s overhangs on these homes hide fascia boards that have been cooking in Valley heat for sixty or seventy years.
When the Decking Needs Replacement
Van Nuys sun does a specific thing to roof decking. The attic side of the plywood or plank sheathing bakes at temperatures that can exceed 140°F in July and August, and that repeated thermal cycling turns the wood brittle. When we tear off old shingles on a 1950s ranch and find decking that cracks under a boot heel, the smart move is re-deck before new shingles go on. Adding re-deck squares changes the bid, and we scope it during inspection whenever possible so you’re not surprised mid-job.
Detached Structures on the Lot
Van Nuys lots are bigger than what you’ll find in Sherman Oaks or Encino to the south, and many of them carry a detached garage, a workshop, and sometimes an unpermitted ADU from the 1980s or 90s. Each structure is its own roof with its own decking age, its own flashing details, and its own permit math. We quote per structure, not just per house, because a single address with three roof planes is three separate scopes of work that happen to share a driveway.
Reroofing in Van Nuys
Reroofing in Van Nuys means either a second layer over an existing shingle roof or a full tear-off and replacement with new materials. Building code allows a reroof over a single existing layer in some cases, but on low-pitch postwar tract roofs with heat-damaged decking underneath, we rarely recommend it. The shingles may look tired on the surface while the structure below is ready to be assessed. On a roof that’s already taken sixty years of Valley sun, putting new shingles over old decking is a gamble we won’t let you take without knowing the odds.
Second Layer vs. Tear-Off
Reroofing over one existing layer saves on tear-off labor and hauling, and on a straight gable roof with solid decking it can be a reasonable option. The cost runs $6,200 to $11,000 for a typical Van Nuys ranch. But if the existing shingles are already brittle enough to crack when walked, that’s a signal the decking underneath has been cooking too long to trust. We’ll tell you which path makes sense after the inspection.
Heat-Baked Decking Under Old Shingles
What we find under a second-generation reroof in Van Nuys is often worse than what’s visible from the ground. The original 1950s plank decking absorbs decades of attic heat, and the shingle layer above it acts like a blanket. By the time the roof is ready for replacement, the decking may be cracked, warped, or soft at the eaves where fascia rot let moisture in. A tear-off quote that includes re-deck is more expensive up front but far cheaper than a section of decking failing and taking new shingles with it two years later.
Trusted Brands We Service in Van Nuys
We’re certified to install GAF, CertainTeed, and Tamko systems, and we stock common accessories for all three locally so Van Nuys jobs don’t stall waiting on parts from a distributor in the Inland Empire. If your roof was built with Owens Corning, IKO, Atlas, or Boral products and you want to stay with the same manufacturer, we’ll order the materials and handle the warranty paperwork. We work with your roof’s brand, not ours. The standard of installation doesn’t change across the seven lines, because the crew on your roof understands each manufacturer’s fastening requirements, flashing details, and warranty conditions before the first bundle comes off the truck.

AfterCommon Roof Replacement Problems We See in Van Nuys Homes
- Sun-killed shingles on low-pitch ranch roofs: Van Nuys summer heat climbs past 100°F regularly, and shingles on a 3:12 or 4:12 pitch absorb that heat all day. Granule loss, curling edges, and shingles that crack when stepped on are the standard failure mode here, not wind or hail.
- Dry-rotted fascia hidden under wide eaves: The 1940s through 60s tract homes west of Van Nuys Blvd were built with generous overhangs, and the original fascia boards tucked under those eaves trap moisture from winter rain. By the time you see peeling paint or sagging gutters, the wood behind the shingle edge may already be gone.
- Heat-cooked attic decking: Plywood and plank decking in Van Nuys attics cycles between daytime heat and nighttime cooling every day from May through October. Over decades, that turns wood brittle, and a tear-off exposes cracks that weren’t visible from below.
- Multiple roof planes on one lot: Detached garages, workshops, and ADUs on Van Nuys parcels each carry their own roof with its own age, pitch, and flashing failures. A quote that only covers the main house misses half the stormwater and heat exposure on the property.

FAQs About Roof Replacement in Van Nuys
Van Nuys is within Los Angeles city limits, so roof replacement permits come from the Los Angeles Department of Building and Safety, not the county. Our team pulls the permit, schedules the inspection, and handles the paperwork from application to final sign-off. The permit covers the roof system itself; when we’re also re-decking, that scope is included in the same permit package. Call (866) 650-8319 and we’ll confirm what your specific address requires before we quote.
Because Van Nuys parcels often carry multiple roof planes. Your house might be 1,400 square feet, but a detached two-car garage adds 400 square feet, a workshop adds another 300, and the covered patio is its own 200-square-foot low-slope section. Each structure gets its own tear-off, decking assessment, underlayment, and flashing, and the hauling distance to the curb adds labor on long lots. We break the quote down per structure so the number isn’t a mystery.
Wide eaves and original wood fascia from the 1940s and 50s trap moisture at the shingle edge, and decades of winter rain wicking into unpainted or peeling fascia boards rot the wood from the inside out. The rot is almost always hidden behind the drip edge or under the shingle overhang, so it only shows up when we lift the shingle edge during tear-off. We inspect the fascia during the initial roof inspection and include replacement in the quote when we can see or suspect it.
Sometimes. If the existing roof is a single layer, the decking is sound, and the pitch is 3:12 or steeper, a reroof over the old shingles can save tear-off costs. But on low-pitch roofs with heat-baked decking or visible granule loss, adding a second layer traps more heat and hides decking failure. Most Van Nuys ranch roofs we inspect are better served by a full tear-off, and we’ll show you why with photos from the attic and the roof surface before you decide.
We stage materials on the driveway or a designated area of the lot, not on the street, and our tear-off crew hauls debris to a roll-off placed at the curb or in the driveway depending on access. Long lots with detached structures at the rear need wheelbarrow runs or a dump trailer, and that labor shows up in the hauling line of our quote. We scope access during the inspection so the final number reflects reality, not a generic square count.
If your Van Nuys roof is at the point where repairs no longer make sense, or if you want a straight answer about whether replacement is even necessary, call (866) 650-8319 to schedule a free, no-obligation roof inspection and written estimate. Gable Roof Repair serves all of Van Nuys, including the 91405, 91406, 91401, and 91411 zip codes, with the same inspection-first, repair-when-it-makes-sense approach on every job.
