Fast, Reliable Roof Replacement Across Van Nuys
Most roof replacements in Van Nuys run between $9,500 and $22,000 depending on roof size, material, and what we find under the old roof once it’s opened up. A typical 1,200 – 1,600 square foot flat or low-slope replacement in the 91401 and 91405 zip codes lands in the $12,000 – $17,000 range for heat-welded modified bitumen with new edge metal and drainage hardware. The honest variable isn’t shingle color or brand sticker price. It’s what the decking, flashing, and drains look like after 60 or 70 years of Valley heat, oak leaf litter, and standing water. Call (866) 361-0798 for a free estimate and an inspection that tells you what your roof actually needs, not what sells fastest.
We work throughout Van Nuys, from the flat-roof tract homes around Hazeltine and Victory to the newer builds near the 405. Our Roof Replacement crews know this housing stock because we’ve torn into hundreds of these mid-century assemblies. When it’s a 1950s built-up roof shedding gravel into the gutters, or a torch-down that’s drying out along the seams, we’ve seen it. And we know what it costs to fix properly in Van Nuys, not in a coastal zip code with different weather and different building realities.
Why Ridge Cap Roof Repair Is Van Nuys’s Preferred Roof Replacement Company
Van Nuys homes punish roofs in ways that coastal LA never does. The summer heat above 100°F bakes membranes and sealants. The UV breaks down asphalt and coatings over years of cloudless July afternoons. Then the first real winter rain finds every seam that heat opened and every drain that oak leaves clogged. That pattern repeats every year. Understanding it is the difference between a roof that dies at year eight and one that runs past twenty.
We inspect before we recommend, and we repair when it makes sense. Replace when it doesn’t. That order matters to us. It’s built into how Noel Cardenas runs crews in the field. Some roofs in Van Nuys need a full tear-off. Others need re-flashing, drain replacement, and five more years. You won’t hear us pushing a $20,000 job on a roof that can be fixed for $4,000.
We also handle the entire job under one crew: inspection, tear-off, and installation. No hand-off to a subcontractor who never saw the original inspection notes. The same people who find the rot decide how to fix it.

Roof Replacement Contractor in Van Nuys
A Roof Replacement Contractor in Van Nuys deals with two dominant roof types: flat or low-slope torch-down and built-up systems on 1940s – 1960s tract homes, and composition shingle roofs on later construction and re-roofs. The job means removing the old membrane or shingles, opening the decking at the edges and low points, cutting out rot, replacing damaged wood, then installing new underlayment, membrane or shingles, edge metal, flashing, and drains. On Van Nuys flat roofs, we also look hard at how water leaves the roof. A beautiful new modified bitumen field with a clogged drain is just a pond waiting to happen.
Full roof replacement here runs $12,000 – $17,000 for a standard flat or low-slope roof. Pitched asphalt shingle replacement on a similar footprint starts closer to $9,500 and can push past $22,000 on larger homes with steep pitch, multiple valleys, or heavy decking replacement. We give written line-item quotes before you sign anything.
What we inspect before quoting
We walk the roof, check the decking from the attic where possible, and verify drain function and edge metal condition. On flat roofs, we probe seams and look for soft spots along the low points. On shingle roofs, we check granule loss, curling, and flashing seals at penetrations and walls. Every quote comes from that walk, not from satellite imagery.
Why decking condition drives the price
When an original 1950s roof comes off and we find rotten decking around the drains or edges, the repair bill changes. That’s the honest variable in Van Nuys. We show you the rot, tell you the square footage, and quote the repair as a separate line item. You decide. No surprise change orders.
Asphalt Shingle Roof Replacement in Van Nuys
Asphalt Shingle Roof Replacement in Van Nuys applies mostly to the pitched roofs on 1960s and later homes, and to homeowners who want to switch a low-slope roof to architectural shingles where the pitch allows. A full architectural shingle replacement on a 1,400-square-foot Van Nuys ranch typically runs $10,500 – $15,000 with new underlayment, leak barrier, drip edge, and flashing. Basic three-tab shingles come in a bit lower, but we rarely recommend them – the heat and UV here chew through three-tab faster than architectural laminate shingles.
Van Nuys heat cycling is the main reason we steer most shingle customers toward architectural shingles from Owens Corning or Atlas. They hold up better under expansion and contraction, and the heavier mat resists the thermal cracking we see on older three-tab roofs after a few 105°F summers.
When we recommend shingles
If the roof pitch is 3:12 or steeper and the decking is sound, composition shingles are a solid choice in Van Nuys. They handle heat better than a low-slope membrane when installed correctly on a pitched roof. We still specify stainless fasteners and sealed valleys, because the first rain after a long dry season finds every gap.
Heat and UV wear
Shingles in Van Nuys don’t fail from hail or wind the way they do in Texas or the Midwest. They fail from slow UV oxidation. Granules loosen, the asphalt dries, and cracks open at the corners. By the time you see granules in the gutters, the roof is usually in its last few years. Inspection timing matters more here than most homeowners realize.
Trusted Brands We Service in Van Nuys
We install and service products from seven manufacturers, including Owens Corning, IKO, Atlas, and Tamko. That matters because no single brand builds the right roof for every Van Nuys home. Some flat-roof jobs call for a specific torch-down system. Some shingle jobs need a heavier architectural mat. Some clients want a specific warranty tier that only one manufacturer offers. We match the material to the building and the budget, not to what we happen to stock. For flat roofs in Van Nuys, we typically specify modified bitumen systems that weld at the seams and hold up under ponding water longer than standard single-ply membranes. The material roster means we are not locked into one warranty structure or one product line.

AfterCommon Roof Replacement Problems We See in Van Nuys Homes
- Ponding water over clogged drains: Under the Valley oaks in 91401 and 91405, leaf litter builds up around roof drains and scuppers. Standing water soaks modified bitumen seams and softens decking along the low points. We find rot along drain edges on nearly half the older flat roofs we open.
- Heat-embrittled sealant at flashing: Summer temperatures above 100°F dry out pipe boot seals, parapet flashing, and edge metal sealant. The material looks fine until the winter rain, then leaks appear. This is one of the most common call-out findings on Van Nuys roofs.
- End-of-life tar-and-gravel roofs: The original built-up roofs from the 1940s and 1950s are decades past their design life. Gravel wears off, exposing the asphalt to UV, and the roof dries out. Failures usually start at parapets and edge metal, where rusted or under-fastened drip edge lets water under the assembly.
- Builder-grade fasteners and edge metal corroding: Original galvanized nails and thin drip edge on Van Nuys roofs are often rusted through at the eave and rake lines. Reusing them on a replacement dooms the new roof to the same early failure. We specify hot-dip galvanized edge metal and stainless fasteners on the replacements we install.

FAQs About Roof Replacement in Van Nuys
Seam failure happens because heat and standing water attack the weakest point first. In Van Nuys, summer UV dries out the modified bitumen seam laps, and winter rain finds its way into any seam that has separated. Add oak leaf litter clogging the drains in 91401 and 91405, and water sits on those seams for days after each storm. The field membrane still looks intact, but the seams open and leak. That’s why we inspect seams with a probe and re-weld or re-seal them on any replacement. If your roof is leaking at the seams, call (866) 361-0798 for an inspection first – replacement isn’t always the right answer.
Only if the roof pitch is steep enough. Most Van Nuys flat roofs sit at a true flat or very low pitch that shingles can’t handle. Architectural shingles need at least a 3:12 slope to drain properly. When a low-slope roof is pitched under that, shingles will leak, curb and all. The better move for a low-slope Van Nuys roof is a properly installed modified bitumen system with reflective coating to cut heat gain. We’ll tell you if a shingle conversion is possible on your roof, and we won’t try to sell one where it isn’t. Call (866) 361-0798 for a straight answer.
Stainless fasteners, hot-dip galvanized drip edge, and sealed pipe boots and penetration flashing. The original builder-grade galvanized nails and thin edge metal on 1950s and 1960s Van Nuys roofs rust through. We specify stainless or hot-dip galvanized hardware on every replacement we install. The cost difference is small – usually a few hundred dollars on an entire roof – but it adds a decade to the edge and flashing life. Cheap hardware is the number one preventable failure we see on Van Nuys re-roofs. Call (866) 361-0798 and we’ll show you the hardware we recommend and why.
On a typical Van Nuys flat roof, a replacement built with inland-spec materials and premium fasteners runs $12,000 – $17,000. A cheap-spec version using builder-grade nails, thin galvanized edge metal, and minimum underlayment might save $800 – $1,500 on the front end. But the cheap version rusts and fails at the edges and flashings within eight to ten years. The inland-spec version runs past twenty. The price gap is about $1,000 to $2,000 on most roofs, and the cheap spec ends up costing a full second replacement within a decade. That’s the real cost, not the quote number. We build the right spec into every Van Nuys quote and show you the hardware upgrade as a line item.
Line up the line items, not the bottom number. Compare decking repair allowances, fastener and edge metal specs, underlayment type, drainage work, and whether the contractor pulls permits. If one Van Nuys bid is $3,000 lower than the other, the difference is probably in the hardware and decking repair allowance, not in the roof itself. Look for builder-grade fasteners or thin galvanized edge metal, and ask the contractor to show you the decking before they cover it. We give written line-item quotes so you can compare apples to apples. Call (866) 361-0798 and we’ll walk you through the quote, spec for spec.
