Roof Replacement in Van Nuys — Written Price, Workmanship Warranty

Trusted Roof Replacement for Van Nuys Homeowners

A new roof in Van Nuys typically runs between $9,800 and $18,500 depending on the material you choose, the size of your home, and whether the old roof needs to come off first. Most replacements take three to five days once we’re on-site, and we handle the entire job in-house so you never have to coordinate multiple contractors. Van Nuys Roofing Co works across seven major roofing material brands, which means your product recommendation comes from what your roof actually needs, not what we happen to stock. Rick Dominguez leads a crew that has seen every failure mode this climate can produce, from sun-rotted underlayment on Sepulveda corridor homes to wind-lifted shingles near Lake Balboa.

Roof Installation

Roof Installation means laying down an entirely new roofing system on a structure, whether it’s a brand-new build or a house where the existing roof has been removed down to the decking. In Van Nuys, we see two main situations: new construction in pockets like Valley Glen where ADUs and garage conversions are common, and older homes in established neighborhoods south of Victory Boulevard where the original roof is too deteriorated to build over. Van Nuys Roofing Co handles both. A standard asphalt shingle roof installation on an average 1,600-square-foot Van Nuys home typically lands between $10,000 and $15,000 depending on pitch, access, and the brand you select.

Full Tear-Off vs. Overlay

California code limits how many shingle layers you can legally stack on a roof to two. When we install a new roof on a home that already has two layers, the old material gets stripped to the decking before anything new goes down. This adds labor but gives us a chance to inspect the sheathing and catch rot that would otherwise stay hidden for another decade.

Material Choice Up Front

Because we work with GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, you choose the roof you want. We’ll walk you through warranty differences, wind ratings, and what holds up best under Van Nuys sun exposure before you commit to anything.

Roof Replacement Contractor

A Roof Replacement Contractor is the company you hire to remove your old roof and install a new one, and picking one makes the difference between a roof that lasts 25 years and one that fails quietly five years in. In Van Nuys, the wrong contractor might push a single brand because that’s all they know or because their supplier gives them a kickback. Van Nuys Roofing Co is the opposite of that model. We quote across seven manufacturers and give you a straight recommendation based on your roof’s pitch, your budget, and how long you plan to stay in the home. Most residential replacements in Van Nuys run between $9,800 for a basic asphalt roof and $18,500 for higher-end dimensional shingles or flat roof systems, so it’s worth understanding how much roof replacement costs for your specific situation.

One Crew, No Subcontracting

Every roof replacement we handle is completed by our own crew. You won’t get a salesman who disappears after the contract is signed and a different crew that shows up a week later. The people who inspect your roof are the same people who tear it off and install the new one.

Warranty Eligibility Across Brands

Single-brand shops can only offer you that brand’s warranty program. Because we work with all seven major manufacturers, we can explain which warranty terms actually pay out when problems happen and which ones are marketing language. You deserve to know the difference before you sign.

Asphalt Shingle Roof Replacement

Asphalt Shingle Roof Replacement is the most common roofing project we complete in Van Nuys, and for good reason – architectural asphalt shingles handle the San Fernando Valley’s heat well, they install fast, and they cost less than tile or metal. Homes in neighborhoods like North Hills and Sherman Oaks typically pay between $9,800 and $14,500 for a full asphalt shingle replacement on an average-size home, while those needing roof replacement in Encino can expect similar pricing. The price depends on whether we’re doing a full tear-off, what brand you select, and whether the decking underneath needs repairs. We install GAF, CertainTeed, Owens Corning, IKO, Atlas, and Tamko asphalt shingles, and we’ll help you pick based on wind resistance and how the color holds up under direct valley sun.

Dimensional vs. Three-Tab Shingles

Dimensional shingles, also called architectural shingles, are about 50% thicker than three-tab and typically carry a longer manufacturer warranty. They also look better on the ranch-style and mid-century homes that dominate Van Nuys. Three-tab is cheaper up front, but what you save now you often give back in lifespan and curb appeal.

Underlayment Matters in Van Nuys

The shingles get the attention, but the underlayment is what actually keeps water out when the Santa Ana winds peel a shingle loose. We quote a high-quality synthetic underlayment on every shingle roof replacement because it resists UV breakdown and stands up to the valley’s summer heat better than basic felt.

New Roof Installation

New Roof Installation in Van Nuys means building a roofing system on a structure that doesn’t currently have a usable roof, or one that’s being completely rebuilt. We see this most often with new ADUs going up in backyards across Van Nuys and Valley Glen, garage conversions, and homes that have been stripped to the studs during a remodel. New installation is a different project from replacement because there’s no old roof to remove and no existing decking to evaluate – we’re starting from the framing up. New roof installation costs typically run from $12,000 to $18,500 depending on the structure size, roof pitch, and the material system you specify.

New Builds Need New Thinking

A new ADU or addition in Van Nuys has to meet current Title 24 energy requirements, which can affect your roofing material choice. Some roofing systems perform better under cool-roof requirements than others. We walk you through what makes sense for your specific structure and building permit status.

Decking From the Start

On a new roof installation, every layer matters because there’s nothing existing to hide behind. We start with properly spaced decking, add the right underlayment for the material going on top, and install flashing around every penetration before the first shingle or tile is set.

Reroofing

Reroofing in Van Nuys is the process of installing a new layer of roofing material over an existing single layer, which saves on labor and disposal costs compared to a full tear-off. It’s only legal in California when the roof currently has one shingle layer or less, and it only makes sense when the existing decking is in solid condition. A reroof in Van Nuys typically costs between $7,500 and $11,000 on a standard single-story home because you’re skipping the demolition, disposal, and deck inspection work. We’ll tell you honestly if your roof is a candidate for reroofing or if a full replacement is the smarter long-term move.

When Reroofing Makes Sense

If your roof is at the end of its life but the decking underneath is still sound, reroofing can save thousands. We inspect the underlayment and deck from the attic side to verify there’s no hidden rot or water damage before we recommend this path. In many Van Nuys homes built in the 1950s and 1960s, the decking is actually in better shape than the shingles on top of it.

When Reroofing Is the Wrong Call

If you already have two layers of shingles, reroofing isn’t an option – code won’t allow a third. And if the decking shows any sign of water damage, nail fatigue, or sagging, we’ll recommend a full tear-off instead. Rick Dominguez’s rule is simple: we don’t build over problems.

Flat Roof Replacement

Flat Roof Replacement in Van Nuys is a specialized job that requires different materials and installation techniques than a sloped shingle roof. We see flat roofs on mid-century homes throughout Sherman Oaks and Van Nuys, on commercial buildings along Van Nuys Boulevard, and on countless garages and additions. A flat roof replacement typically costs between $9,500 and $16,000 depending on the square footage and the system you choose – modified bitumen, single-ply, or coated foam. Flat roofs fail differently than pitched roofs because water doesn’t run off; it sits and finds any weak seam. We install flat roof systems that handle standing water and valley heat without the leaks that plague older flat roof installs.

Drainage Is Everything

On a flat roof, the slope that matters is the one built into the decking, not the roof surface itself. A flat roof that looks flat to the eye should still have a slight pitch toward its drains. We check drainage patterns before recommending any flat roof replacement because even the best membrane will fail if water pools in the same spot for years.

Coating vs. Membrane Systems

Van Nuys flat roofs respond well to reflective coatings, which reduce heat absorption and can lower cooling costs. We’ll explain the lifespan differences between a coated foam system, a single-ply membrane like TPO, and traditional modified bitumen so you can choose based on the actual conditions of your roof, not a brochure.

Brands We Service

Van Nuys Roofing Co works with seven of the leading roofing material manufacturers because no single brand is right for every roof. GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, Boral – if it goes on a roof, we know how to install it to spec, register it for warranty, and stand behind the installation.

We service and install GAF and CertainTeed shingles regularly on Van Nuys homes, and we know the installation requirements and warranty terms for each product line. Owens Corning and IKO give homeowners in the mid-price range solid options with strong wind ratings. Atlas and Tamko are brands we recommend when a specific color or profile matters to the homeowner. Boral tile is heavier and needs specific deck support, but it’s a great fit for certain architectural styles in the valley. Whether you have GAF on the roof today or you’re leaning toward Boral for the next one, we can help you make the right call.

Signs You Need a Pro Right Now

• Granules accumulating in the gutters. Asphalt shingles shed their ceramic granules as they near the end of their life, and those granules are what protect the underlying asphalt from UV breakdown. If you’re seeing a consistent buildup in your Van Nuys gutters, the shingles are degrading faster than they should.
• Daylight visible through the attic boards. If you can see sunlight coming through gaps in your roof decking from inside the attic, water can get through the same gaps. This is a structural issue that no amount of patching will fix. Call us to inspect before the next winter rain arrives.
• Shingles curling or lifting at the edges. Curled shingles in Van Nuys are usually the result of heat and moisture cycling, and once they curl, the seal strip breaks and wind can get underneath. After one good Santa Ana event, a small curl becomes a missing shingle.
• Water stains on ceilings after rain. A ceiling stain means water has already made it through the roofing system and the insulation below it. By the time you see the stain, the leak has likely been active for weeks or months. An inspection will locate the penetration point.
• Sagging areas you can see from the street. A visible dip or wave in your roofline is rarely a shingle problem; it’s usually a decking or framing problem. When the roof structure itself is compromised, delaying work makes the eventual replacement more expensive and more extensive.

Our Process, Step by Step

1. 1
   Inspection and documentation. We start with a full inspection of your roof from above and below, including the attic and decking. We document everything with photos so you see exactly what we see before any recommendation is made. Inspection is available as a standalone service, so there’s no pressure to buy anything.
2. 2
   Straight recommendation. We walk you through the findings and tell you whether repair or replacement actually makes sense. If replacement is warranted, we quote multiple material options across the brands we work with and let you decide based on price, lifespan, and look.
3. 3
   Written estimate and schedule. Our estimate is line-item, so you know exactly what the labor, materials, disposal, and permit costs are. We don’t book a job until the scope is clear and the price is locked. No change orders on straightforward replacement work.
4. 4
   Removal and deck inspection. On installation day, the crew tears off the old roof and inspects every square foot of decking. If we find rot or damage that wasn’t visible from the attic, we repair it before new material goes down. You’ll be told about any deck work before we proceed.
5. 5
   Installation and cleanup. The new underlayment, flashing, and roofing material are installed to manufacturer spec throughout. After installation we run a magnetic sweep to pick up every loose nail, and we walk the roof before we leave to confirm the work is done right. Your warranty registration is filed on your behalf.
