Fast, Reliable Roof Replacement Across Van Nuys
Roof replacement in Van Nuys usually runs between $9,800 and $18,500 for a full tear-off and re-roof on a typical 1,200-square-foot 1950s bungalow, depending on whether you’re doing a standard asphalt shingle or upgrading to an architectural profile. If you’re in Van Nuys and your roof is on its second shingle layer, we’ll likely recommend a full tear-off rather than an overlay, because the spaced sheathing underneath those postwar roofs hides deck damage you can’t see from above. Call (866) 942-4187 and we’ll come out, get on the roof, and tell you exactly what you’re working with before any money changes hands.
We know Van Nuys roofs because we’ve pulled enough of them apart. The tract homes off Van Nuys Boulevard, the dingbat apartments near Victory, the bungalows between Sherman Way and Oxnard – they all share a DNA that a generic roofer from outside the Valley doesn’t recognize. Our Roof Replacement team spends its days diagnosing the specific failure patterns of 1940s and 50s construction, not guessing at them.
Why Orange County Roofing Co Is Van Nuys’s Preferred Roof Replacement Company
We’re not the cheapest bid in Van Nuys and we won’t pretend to be. What we are is the company that tells you the truth about what’s under your shingles. Van Nuys homeowners call us after another contractor quoted an overlay without ever checking whether the decking below could hold another layer. We show up, we look, and we explain what we find in plain English.
Kurt Hensley runs our roofing operation and sets the standard for how we handle every Van Nuys job: document what’s there, explain what needs to happen, and quote a fixed price that doesn’t shift once the tear-off starts. That approach matters more on Valley tract homes than anywhere else, because surprises hide under those original roofs. We’ve been on enough Van Nuys tear-offs to know what we’re likely to find before the first shingle comes off, and that’s exactly the kind of local knowledge you want when you’re pricing a five-figure replacement.
We install products from seven major manufacturers – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – because no single brand fits every Van Nuys roof. A shallow-pitch bungalow with afternoon sun exposure needs a different shingle than a flat-roof dingbat, and we’d rather show you the trade-offs than steer you toward whatever’s easiest for us to stock. Our inspection tells you exactly what your roof needs, nothing more.

New Roof Installation in Van Nuys
New roof installation in Van Nuys means starting from the deck up, and that’s the most common scenario we see on any original 1940s or 50s roof that’s never been re-covered. You’re not just swapping shingles – you’re replacing decking where the spaced sheathing has warped or cracked, installing new underlayment, re-flashing every penetration, and sizing ridge ventilation to your home’s square footage. A new roof on a standard Van Nuys bungalow typically runs $12,000 to $18,500 with architectural shingles, and the job takes three to five days depending on decking condition.
What makes Van Nuys new roof work different from other parts of Los Angeles is the thermal cycling. Summer highs over 100°F bake the original mastic at every pipe boot and chimney flashing until it’s brittle. When we do a new installation here, we use sealants and flashing materials specified for that heat load, not whatever’s standard on a coastal job.
Full Tear-Off and Re-Deck
Most Van Nuys homes with original roofs need this. The 1950s spaced sheathing – boards with gaps between them – doesn’t meet modern code for shingle fastening, and it hides rot you can’t detect from the attic. We remove everything down to the rafters, replace damaged decking, and install solid sheathing before the new roof goes on. Expect this to add $1,800 to $3,000 to the total, but it’s the difference between a roof that lasts twenty years and one that starts sagging in five.
Architectural Shingle Upgrades
If you’re replacing a roof on a Van Nuys bungalow and plan to stay, architectural shingles are worth the premium. They carry longer manufacturer-backed warranties and hold up better under Valley UV exposure, which degrades three-tab shingles fast. An architectural upgrade adds $1,200 to $2,600 to a standard re-roof, and you’ll see the difference in both curb appeal and how the roof handles summer heat.
Reroofing in Van Nuys
Reroofing in Van Nuys is the single most common job we do, because thousands of these tract homes were already re-covered once in the 1980s or 90s and the second layer is now failing. A reroof with a full tear-off of both existing layers runs $11,500 to $16,800 on a typical bungalow, and that includes dump fees, new underlayment, drip edge, and ridge vent. We don’t recommend overlays on Van Nuys homes with spaced sheathing, because a third layer over a deck that’s already compromised is a future lawsuit, not a roof.
Reroofing also includes the flat and low-slope work that dominates the apartment stock. Van Nuys dingbats with tar-and-gravel roofs need membrane work and seam reinforcement far more often than sloped shingle homes, and the skills are different. We handle both on the same project when a property has mixed roof types.
Flat Roof Membrane Replacement
On Van Nuys flat roofs, the failure point is almost always the seams and penetrations, not the membrane itself. Ponding water after winter storms finds every weak joint, and the hot-day cold-night cycle works those seams loose over time. We strip the old membrane, reinforce the seams, install new flashing at every penetration, and use sealants rated for Valley heat rather than coastal conditions.
Decking Repair During Reroof
Here’s what we actually see on Van Nuys reroofs: the original decking is fine under the field, but cracked and rotted around the chimney, the plumbing vents, and wherever an old satellite dish was mounted. We replace only what’s failing. That keeps your reroof cost honest – you pay for the decking you need, not a full re-deck someone tacked on to inflate the bid. A typical reroof includes $800 to $2,200 in targeted decking replacement.
Trusted Brands We Service in Van Nuys
We carry Owens Corning, IKO, and Atlas among our seven-brand lineup, and we stock enough local inventory for Van Nuys jobs to avoid the two-week supply delays that hit some contractors during fire season. That matters when your roof is already open and the weather window is tight. Because we install products from competing manufacturers, we can recommend honestly – the right material for your Van Nuys roof, backed by the manufacturer’s own warranty, not the brand that gives us the best margin. GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, Boral – we install them all, so the recommendation is about your roof, not our supplier.

AfterCommon Roof Replacement Problems We See in Van Nuys Homes
- Two shingle layers over spaced sheathing. The original 1940s or 50s roof was re-covered once, and now a second layer is failing. We pulled two layers off a 1952 bungalow off Van Nuys Boulevard near the 91405 line and found spaced sheathing with sun-cracked mastic at every penetration – so we went full tear-off and re-deck rather than an overlay, because a third layer would have trapped heat and hidden the cracked decking until it failed underfoot.
- Flat-roof dingbat seam failure. On the flat-roof apartment a block over, ponding after the last winter storm had found every seam. We replaced the flashing with hot-dip galvanized and set marine-grade sealant at the joints. The freeze-thaw of a hot Valley day and cold night works every seam and flashing mastic loose, and the only real fix is full seam reinforcement, not spot patching.
- UV-baked sealant at penetrations. Van Nuys summer heat over 100°F dries out the sealant around pipe boots, chimneys, and vents years before the shingles themselves wear out. By the time a homeowner notices a leak, water has already been getting in for months, and the decking below is usually the first casualty.
- Asphalt shingle fracturing from thermal swings. Day-night swings of 30 degrees or more crack aging asphalt shingles on Valley roofs faster than coastal roofs ever see. What looks like normal wear is actually the shingle granule surface failing from expansion and contraction, and it means your roof is aging in dog years compared to a Santa Monica roof of the same age.

FAQs About Roof Replacement in Van Nuys
A third layer is almost never the right call on a Van Nuys bungalow, because the spaced sheathing underneath was never designed for that weight, and the heat trapped between layers accelerates deck failure. The honest answer is that most of these homes need a full tear-off and re-deck. We’ll confirm what’s under your roof for free before you commit to anything – call (866) 942-4187 and we’ll get on the roof and tell you the truth.
No. Van Nuys is a San Fernando Valley heat island, not a coastal zone, so salt-air marination is minimal; the real material killer is 100°F-plus summer thermal cycling combined with the 1940s-50s tract assembly of spaced sheathing under two shingle layers. That’s why our fasteners and finishes get specified for UV and heat-aging rather than chloride attack, and why the exact same upgrade that’s mandatory in Redondo Beach is optional but still smart on a Van Nuys bungalow. You’re paying for heat resistance, not salt resistance, and any roofer who tells you differently is selling you the wrong spec. Call us at (866) 942-4187 for a straight answer.
Coastal-spec work uses stainless or hot-dip galvanized fasteners and marine-grade finishes to resist chloride corrosion from salt air, and it adds $2,000 to $4,000 to a typical roof replacement in beach cities. Inland-spec work, which is what Van Nuys roofs actually need, prioritizes UV-resistant sealants, heat-rated underlayment, and ventilation sized for 100°F summer days. The cheap spec costs more within a decade in Van Nuys, because heat destroys ordinary sealant fast. Call (866) 942-4187 and we’ll explain which upgrades make sense on your specific roof.
Look at three things: whether the bid includes a full tear-off or an overlay, what decking replacement is actually specified, and what sealant and flashing materials are listed. A bid that’s $3,000 lower usually means an overlay over compromised decking, skip-on re-decking, or coastal-spec materials that don’t belong on a Valley roof. We give every Van Nuys homeowner a written line-item quote so you can put our bid next to any other and see exactly where the differences are. Estimates are free.
Flat-roof dingbats fail at the seams because ponding water after winter storms sits on the membrane, and the hot-day cold-night cycle of the Valley works every seam and flashing mastic loose. Spot patching doesn’t fix it – the only durable repair is full seam reinforcement with hot-dip galvanized flashing and marine-grade sealant at every joint. We do this work on Van Nuys apartment buildings regularly, and we’ll give you an honest assessment of your building’s flat roof. Call (866) 942-4187 to set up an inspection.
