Roof Replacement in Van Nuys — Written Price, Workmanship Warranty

Fast, Reliable Roof Replacement Across Van Nuys

Roof replacement in Van Nuys typically runs $12,000 to $24,000 for a full tear-off on an average single-family home, with flat roof systems on the post-war tract houses coming in lower and steep-slope architectural shingle work on the newer hillside homes running higher. We’re in Van Nuys every week, and we know the exact mix of heat, UV, and inland-reaching salt air that decides whether a roof here lasts 15 years or 30. Call (866) 974-2271 and Manny Cordero will walk you through what your specific roof actually needs, not what a call center script says it needs.

Here’s the thing most roofers won’t tell you about Van Nuys: the air here is doing two jobs at once. The same onshore flow that pushes valley heat over 100°F in summer also carries enough coastal moisture inland to corrode your roof’s fasteners while the shingles above them bake in the UV. That combination means a Van Nuys replacement has to be specified for both conditions simultaneously, and the cheap inland spec that ignores corrosion is the one that fails inside a decade. We build every quote around that reality because we see it on nearly every tear-off we do in 91401, 91405, 91411, and the surrounding Valley.

Why Koreatown Roofing Is Van Nuys’s Preferred Roof Replacement Company

We’re not a general contractor who subs out the roof to whoever’s available that week. Roof Replacement is one of exactly three things we do: inspection, repair, and replacement. That’s the whole list. Every crew we send to Van Nuys is a roofing crew, not a rotating cast of subcontractors, and the same team that tears off your old roof is the team that lays the new one. Property owners in Van Nuys call us because they want a roofing specialist who can explain the difference between a modified bitumen system and a built-up tar-and-gravel roof without making it sound like a sales pitch.

Manny Cordero built this company around neighborhood-level accountability, the kind where our reputation lives and dies within the communities we serve. That means when we quote a tear-off on a Van Nuys Boulevard flat roof, we’re quoting it to a neighbor, not a lead from a call center queue. We also carry real material choice, not a single-brand take-it-or-leave-it pitch. We work with GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so when we recommend a material for your Van Nuys roof, it’s because that material fits your deck, your pitch, and your budget, not because it’s the only thing we happen to stock.

Flat Roof Replacement in Van Nuys

Flat Roof Replacement in Van Nuys is a different job than it is almost anywhere else in Los Angeles, because much of the city’s housing stock was built between the 1940s and 1960s with low-pitch or true flat roofs that have been patched, layered, and re-patched for decades. A standard flat roof replacement here runs $9,000 to $16,000 depending on deck condition, square footage, and whether the old system gets stripped to the sheathing or overlaid, which we rarely recommend for reasons we’ll get into below.

Built-Up and Modified Bitumen Systems

Most original Van Nuys flat roofs are built-up tar-and-gravel, layers of hot-mopped asphalt and roofing felt that were state of the art in 1955 and are now cracking, alligatoring, and holding water in ways you can’t see from the curb. When we replace one, we typically specify a modern modified bitumen system with heat-welded seams and stainless or hot-dip galvanized fasteners, because the builder-grade galvanized hardware those old roofs were attached with corrodes in Van Nuys air. The membrane might last 25 years, but the fasteners often let go first.

What a Tear-Off Actually Reveals

In the older Van Nuys tracts around 91401 and 91405, we almost never find just one roof layer. We find two, three, sometimes four unpermitted layers of tar paper and gravel that were never stripped, just covered over. Each layer adds dead weight and traps moisture between itself and the layer below, and by the time we open it up, the decking underneath is often soft from years of hidden leakage. That’s why an honest flat roof quote in Van Nuys includes a contingency for decking replacement, and why a roofer who quotes a simple overlay without looking underneath is quoting you a problem, not a roof.

Roof Installation in Van Nuys

Roof Installation in Van Nuys means new construction, additions, and full re-roofs where the deck gets replaced down to the framing, and the numbers here run $14,000 to $28,000 depending on square footage, pitch, and whether you’re going with architectural asphalt shingles or a flat roof system. New construction in Van Nuys, especially ADUs and small multi-family buildings along corridors like Sepulveda and Van Nuys Boulevard, is subject to Title 24 cool-roof requirements for certain low-slope applications, which is where reflective coatings and lighter-colored membranes come in. We’ll handle the Title 24 side so you don’t have to decode it.

New Construction Roofing

If you’re building a new home or ADU in Van Nuys, the roof is actually one of the last places to cut corners. The decking, underlayment, and fasteners all have to work together from day one, and in this climate that means specifying corrosion-rated hardware and UV-stable materials from the start. We coordinate directly with your general contractor or we’re the contractor on roofing-only builds, and we pull permits and pass inspections on every new construction job we take on in Van Nuys.

Steep-Slope Shingle Roofs

Not everything in Van Nuys is flat. The neighborhoods up toward Valley Glen and the hillside pockets of Sherman Oaks have plenty of pitched roofs, and those benefit from architectural shingles from GAF, CertainTeed, Owens Corning, or similar. Architectural shingles handle Van Nuys heat better than basic three-tab because the extra dimensional layer gives them more structural rigidity against thermal expansion and contraction, plus they meet most fire and wind code requirements in the Valley without extra upgrades.

Trusted Brands We Service in Van Nuys

Your roof, your material choice. That’s not a slogan, it’s how we price work. We install and service roofs from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, which means the recommendation you get is based on your Van Nuys deck condition, your pitch, and your actual budget, not on which single brand we’re obligated to push this quarter. We work with the brands you already trust because we’d rather match the product to the local conditions than tell you why the only thing we stock is “just as good.” For Van Nuys specifically, that matters most with flat roof membranes and cool-roof products, where a UV-stable modified bitumen or reflective cap sheet makes a measurable difference in your summer cooling bill.

Common Roof Replacement Problems We See in Van Nuys Homes

• Corroded fasteners on otherwise intact roofs: The same onshore air that carries coastal moisture into Van Nuys pits galvanized nails and screws, so we open roofs where the shingle or membrane looks fine but the fasteners have rusted through. We specify stainless or hot-dip hardware on every replacement for exactly this reason.
• Hidden layers on 91401 and 91405 flat roofs: Older Van Nuys flat roofs often have two or more unpermitted layers of tar paper and gravel that were never stripped. That adds weight, hides leaks between layers, and means a “simple” tear-off frequently becomes a decking replacement once we get everything off.
• UV-brittled materials that fail after the first winter rain: Van Nuys summers bake shingles and modified bitumen until they crack, and those cracks sit there invisible all summer until the first real rain finds them. Pre-rain inspections in October and November catch these before they become interior damage.
• Pre-1980s materials requiring asbestos checks: Many original Van Nuys roofs predate the asbestos ban, so before disposal we check for asbestos in old felt, mastic, and underlayment. It’s a quick test and it keeps disposal legal and safe for everyone on the property.
