Fast, Reliable Roof Replacement Across Northridge
Roof replacement in Northridge typically runs $9,000 – $18,000 for a standard asphalt shingle tear-off on a 1,600 – 2,200 sq ft ranch home, and $22,000 – $45,000 when concrete tile is involved. We get most Northridge jobs fully permitted and underway within two to three weeks of your signed estimate. Call (866) 321-6172 to get a straight answer on your roof, not a sales pitch.
We’re Van Nuys Roofing Co, and we work Northridge constantly. Our crews know the tract homes off Reseda Boulevard, the hillside lots above Rinaldi, the newer builds east of Balboa, and everything in between. More important, we know what’s up there before we even set a ladder. Northridge has a roofing story that no neighboring city shares, and it directly affects whether your next roof lasts 15 years or 40.
Why Van Nuys Roofing Co Is Northridge’s Preferred Roof Replacement Company
Rick Dominguez built Van Nuys Roofing Co around a simple operating rule: we inspect first, recommend second. That’s not a slogan. It’s the only way to give an honest answer on a Northridge roof where what’s visible from the street often has nothing to do with what’s actually failing underneath.
We’re fluent in seven major roofing material brands – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That matters in Northridge because so many homes here carry concrete tile that was re-laid after the 1994 earthquake. Single-brand shops will push you toward whatever they stock. We’ll tell you whether your existing tile goes back on, whether an asphalt shingle replacement makes more sense, and which manufacturer’s warranty actually fits the job.
Northridge homeowners call us because we return calls, show up with a full crew, and pull permits like it’s routine – because it is. Our inspections are standalone. You can hire us to tell you the truth about your roof without any expectation that you’ll buy a replacement. That’s the trust model that keeps our Northridge schedule full.
Styles & brands we work with
Roof Replacement Contractor in Northridge
A Roof Replacement contractor in Northridge handles full tear-offs, new decking where rot or seismic stress has compromised the sheathing, and complete re-roofs to current California building code. The 1994 earthquake left this city with a specific legacy: thousands of tile roofs were re-laid over new underlayment between 1994 and 1996, and that underlayment is now 30 years old and failing while the tile above still looks fine.
As a full-cycle roofing company, we handle inspection, repair, and replacement in-house. No subcontracted crews. No referral roulette. When a Northridge homeowner needs a roof replaced, we assess the decking, check the rafter connections and shear wall continuity where quake retrofits come into play, and write a contract that tells you exactly what gets done and what it costs.
Northridge decking and underlayment realities
On a 1968 ranch home off Reseda Boulevard in ZIP 91325, our crew pulled original concrete tile and found it perfectly sound, but the 1995-era underlayment beneath was brittle and cracking along every valley. We re-laid the same tiles over new ice and water shield and synthetic underlayment, replaced rotted decking at two penetrations, and installed new drip edge and ridge vent. The homeowner kept their original tile and got a fully upgraded roof.
When a full replacement beats a repair
In Northridge, if your underlayment is failing under sound tile, patching is a waste of your money. The water is already traveling. By the time you see a ceiling stain, the decking has been wet through multiple winter rain cycles. A full replacement costs more up front, but it stops the rot at the source and gives manufacturer warranty eligibility that a patch can’t touch.
Asphalt Shingle Roof Replacement in Northridge
Asphalt shingle roof replacement in Northridge runs $9,000 – $18,000 for a standard tear-off and re-shingle on a typical 1950s – 1970s ranch, and it’s the most common route when a homeowner wants to retire failing tile without paying tile prices. The San Fernando Valley sun bakes asphalt shingles hard. Northridge summers routinely push attic temperatures past 150°F, and shingles that would last 30 years in a coastal climate often fail here in 18-22.
That accelerated degradation is why we recommend architectural shingles for Northridge replacements. They carry higher wind ratings – most qualify for the 130 mph rating required across much of the Valley – and their heavier laminate construction handles thermal cycling better than 3-tab. Brand matters here too. We install GAF, CertainTeed, Owens Corning, IKO, Atlas, and Tamko architectural lines, and we’ll match the shingle to your roofline and budget rather than steering you to whatever’s on the truck.
What full replacement includes
Every asphalt shingle replacement we do in Northridge includes a full tear-off to bare decking, new synthetic underlayment, new drip edge, new flashing at all penetrations, and new pipe collars. We do not shingle over old shingles. That’s a shortcut that hides decking damage and voids manufacturer warranty coverage.
Roof decking replacement in Northridge
On older Northridge homes, we expect to replace some decking. Quake-era repairs, repeated thermal cycling, and 30 years of occasional winter rain take a toll on plywood and OSB. We write a decking allowance into every Northridge contract so the cost is on the table up front, not a surprise mid-job. If we open the roof and find more rot than the allowance covers, you see a written change order with pricing before we cut another board.
Trusted Brands We Service in Northridge
Your roof, your material choice. That’s the core difference with Van Nuys Roofing Co. Where most Valley roofers stock one or two brands, we’re fluent in seven: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Northridge homeowners, that means we can source materials locally and quickly – no waiting on a single distributor – and we can give you an honest comparison of warranty terms, wind ratings, and real-world lifespan in Valley heat. Seven leading brands, one crew that knows them all.
Common Roof Replacement Problems We See in Northridge Homes
- Quake-era re-lays hiding bad underlayment: Sound original concrete tile sitting on brittle 1995-era underlayment that’s cracking along valleys and letting winter rain reach the decking. This is the single most common Northridge failure we open up.
- UV-baked asphalt shingles: Hot, dry Valley summers cause granule loss and curling well before the shingle’s rated lifespan. Northridge gets some of the most intense sun exposure in the San Fernando Valley.
- Slipped or re-seated tile from 1994 repairs: Open laps and exposed fasteners where tiles were re-set after the earthquake now channel water into fascia and soffit, especially on homes in ZIP 91325 and 91324.
- Aged flashing and penetrations: The occasional winter rain Northridge gets isn’t heavy, but it’s enough to exploit any flashing that’s dried out, cracked, or lifted over 40-50 years of thermal cycling.

FAQs About Roof Replacement in Northridge
Because after the 1994 earthquake, thousands of Northridge homes had their original concrete tile pulled, new underlayment installed, and the same tile re-laid. That underlayment is now 30 years old and brittle, while the tile – never replaced – is still structurally sound. So we see good tile over failing underlayment far more often than roofers in Granada Hills or Reseda, where fewer roofs got quake-era re-lays. The fix is a full removal, new underlayment, and re-lay of the original tile. Call (866) 321-6172 for a free inspection and we’ll tell you if your underlayment is at end of life.
We call you from the roof, show you what we found, and give you a written change order with pricing before we do anything beyond stopping water intrusion. Every Northridge contract we write includes a decking allowance for expected rot, but if the quake or a long-hidden leak did structural damage, you’ll see the exact cost and approve it first. That’s non-negotiable on our jobs. We don’t like change orders any more than you do, but we’d rather be honest mid-job than cheap up front.
Yes, when you install the right shingle line and follow manufacturer’s installation specs. Most architectural shingles from GAF, CertainTeed, and Owens Corning carry 130 mph wind ratings, which satisfies the wind design requirements in effect across much of the Valley. We install to manufacturer spec every time – correct nail pattern, ring shank nails, and no shortcuts – because that’s what keeps your warranty valid and your shingles on the roof when Santa Ana winds hit Northridge in the fall.
Look for three things: identical material scope, identical underlayment and flashing work, and an explicit decking allowance. In Northridge, the biggest bid difference comes from what’s left out – a cheap bid often omits new underlayment, reuses old flashing, or doesn’t include decking replacement. Ask for line-item pricing. Ask what happens when they find rot. If they can’t answer those questions in writing, keep looking. Our estimates are free and detailed enough to compare line by line against anyone’s.
Because Northridge summer heat accelerates material failure in ways that coastal climates never see. Asphalt shingles lose granules and curl years earlier. Clay tile holds up, but the underlayment beneath it bakes and gets brittle. Sealants crack. Flashing lifts. When you’re choosing materials for a Northridge roof, thermal performance and UV resistance matter more than anything else – and we’ll factor that into our recommendation, whether that means architectural shingles with a high reflectivity rating or re-laying your existing tile over new high-temp underlayment.
