Our shop is in Van Nuys, about 10 minutes from most Northridge neighborhoods, which means we’re already in your area most weeks.
Northridge roofs have a history most other San Fernando Valley cities don’t share. The 1994 earthquake didn’t just crack walls. It shifted thousands of tile roofs, and the repairs made back then are now hitting the 30-year mark. That’s the roof you’re probably living under. We know exactly what to look for, and we won’t sell you a new roof if a Roof Repair team can make yours watertight again.
Why Van Nuys Roofing Co Is Northridge’s Preferred Roof Repair Company
We work across seven major roofing material brands: GAF, CertainTeed, and Owens Corning among them. Most local crews push one brand because that’s what their supplier discounts. We don’t have that problem. If your Northridge home needs a Boral tile matched or a CertainTeed shingle replaced, we know the specs and the installation requirements for each. Your roof, your material choice. That matters here, where so many homes still carry original 1970s concrete tile that needs careful matching, not a generic patch.
Rick Dominguez runs our crew, and he’s been clear about how we operate from day one: we inspect first, recommend second. That’s not a slogan. It’s how we quote. When you call us about a leak near the Northridge Recreation Center or up on a hill off Reseda Boulevard, the first thing we do is get on the roof and look. If a repair makes sense, we say so. If replacement is the honest answer, we’ll tell you why with photos and numbers. We’d rather you trust us on a $400 fix than doubt us on a $12,000 job.
We pull up in Northridge regularly enough that our crews know the streets, the HOA territories, and the older tract layouts. We’ve repaired roofs near CSUN, in the neighborhoods off Nordhoff Street, and out on the larger lots toward the 118. That local familiarity means faster scoping and fewer surprises once the job starts.
Styles & brands we work with
Roof Leak Repair in Northridge
Roof Leak Repair in Northridge typically costs $350 to $900 for a single penetration or flashing point, and the job usually takes half a day. The leaky roof you’re dealing with is often not where you think it is. Water enters at a cracked vent boot or a corroded flashing seam near a valley, then travels along a rafter before dripping into the living room. We trace the path, not just the stain. On Northridge’s 1950s and 1960s ranch homes, we regularly find the real entry point 6 to 10 feet from the interior watermark.
Underlayment and Tile Re-Setting
In Northridge especially, we see concrete tile roofs that look fine from the curb but leak after the first real winter rain. The 1994 quake repairs often kept the original tiles and replaced only the underlayment beneath the broken sections. That underlayment is now 30 years old, brittle, and cracked. We lift the tiles, replace the underlayment, re-set the original tile, and the roof holds. This runs $2,400 to $4,800 for a typical section.
Flashing and Valley Work
If your leak shows up where two roof slopes meet or near a chimney, you’ve probably got flashing corrosion or a valley that’s lost its seal. On quake-patched roofs, drip edge corrosion is sneaky: water creeps behind the fascia and rots the soffit before you ever see a ceiling stain. Repairing flashing and valley seams in Northridge runs $250 to $750 depending on linear feet and access.
Emergency Roof Repair in Northridge
Emergency Roof Repair in Northridge is what we do when a branch goes through a section of shingles during a Santa Ana wind event or a tile roof finally lets go during a heavy downpour. The cost for emergency tarping and sealing runs $350 to $600, with the full repair following once conditions dry out. We don’t charge a separate “emergency fee.” You pay for the repair. The tarp is part of stopping the damage. Call (866) 321-6172 and we’ll dispatch from Van Nuys.
Storm and Wind Damage
Northridge sits in the path of the same Santa Ana winds that hit Porter Ranch and North Hills. Blow-offs at ridge vents and starter strips are common on aging asphalt shingles that have baked in the Valley sun for 20 years. We re-secure or replace those sections, but we’ll also tell you if the underlying shingle is past its useful life. No point patching a roof that’s going to blow off again in six months.
Hidden Rot and Structural Checks
Some emergency calls turn out to be slow leaks that finally soaked through. When we open those up, we check the decking, the fascia, and the rafter tails before we button anything back up. Hidden rot doesn’t get fixed by a $300 patch. We’ll show you what we found, give you a straight recommendation, and handle the repair or replacement under one roof.
Trusted Brands We Service in Northridge
GAF, CertainTeed, Owens Corning, and Boral are brands we stock parts for and install regularly. When your Northridge home has a concrete tile roof from the 1970s, matching the existing tile profile matters. We know Boral’s line. If you’ve got architectural asphalt shingles, we can match GAF or CertainTeed colors without guessing. Because we’re not tied to one manufacturer, we recommend the product that fits your roof and your budget, not the one our supplier pushed this quarter. That’s the whole point of our shop. Seven leading brands, one crew that knows them all.

AfterCommon Roof Repair Problems We See in Northridge Homes
- Failing underlayment beneath intact tile. The 1994 earthquake spawned a generation of tile re-roofs that reused original tiles over new underlayment. That underlayment is now brittle and cracked, and leaks only show up after winter rains. We’ve re-laid dozens of these in Northridge’s 91325 and 91324 ZIP codes.
- Baked and cracked asphalt shingles. The San Fernando Valley sun is relentless. Shingles on 1950s through 1970s tract homes dry out, curl, and blow off at ridge vents during Santa Ana winds. Sealing and replacing those sections before winter saves the decking underneath.
- Corroded drip edge and fascia rot. Quake-patched roofs often got sloppy drip edge work, and 30 years of winter moisture has done its work. Water intrudes behind fascia boards and rots the soffit. This shows up as peeling paint on the eaves, not a ceiling stain.
- Improperly sealed penetrations. Vent pipes, plumbing stacks, and chimney flashing from quake-era repairs were often sealed with whatever was on hand. Those seals failed years ago. We replace vent boots and re-flash chimneys to stop the slow leaks that turn into big decking problems.

FAQs About Roof Repair in Northridge
In Northridge, the most common cause is failing underlayment beneath intact concrete tile. After the 1994 earthquake, thousands of tile roofs were re-laid with reused tiles over new underlayment. That underlayment is now 30 years old and failing. The tiles protect it from sun, so it looks fine from above, but once winter rains come, water finds the cracked underlayment and gets through. We remove the tiles, replace the underlayment, and re-set the original tile. In ZIP codes 91325 and 91324, we see this pattern constantly. It’s far less common in Granada Hills or Reseda, which saw less intense shaking in ’94. Call (866) 321-6172 and we’ll do an inspection to confirm it.
We scope it the same way we’d scope any Northridge property: we walk the land first. Large lots in Northridge often come with detached garages, ADUs, horse facilities, or storage buildings that need roof repair too. We map every structure, check drainage flow across the open lot, and identify where county permitting may apply, especially if septic setback lines or well locations affect the repair scope. Then we quote each structure separately so you see exactly what you’re paying for. No lump-sum guesswork. For a detailed line-item estimate, call (866) 321-6172.
A “square” in roofing means 100 square feet of roof surface. Roofers price materials and labor per square. If we’re replacing a section of shingles or underlayment on your Northridge home, the quote will list squares, not “a section.” That keeps the math honest. When you compare quotes from other Northridge roofers, make sure they’re quoting the same square count, not a vague area. We give you exact square measurements on every written quote. Call (866) 321-6172 and we’ll measure your roof and price it line by line.
Yes. We handle storm and wind damage across Northridge, from Santa Ana blow-offs to rain-driven underlayment failures. We tarp first to stop the water, then assess the full damage once things dry out. We work directly with your insurance adjuster when you file a claim, and we document everything with photos so the adjuster sees what we see. If your roof has storm damage, call (866) 321-6172. We’ll get out to Northridge quickly and start the stop-loss work.
Yes, and we take those rules seriously. Northridge has HOA-governed neighborhoods where roof repairs must match existing materials and colors, and some pockets have stylistic requirements tied to the original 1950s and 1960s tract designs. We’ll review the HOA’s guidelines with you before we quote, and we’ll match tile profiles or shingle colors to the board’s standards. If the HOA needs documentation, we provide it. We’ve done enough Northridge work to know which HOAs are strict and which just want the repair done cleanly. Tell us your HOA situation when you call (866) 321-6172 and we’ll factor it into the quote from the start.
If your Northridge roof is leaking, lifting, or losing materials, the fix starts with an honest inspection. We’ll tell you whether repair or replacement actually makes sense for your roof, your lot, and your budget. Call Van Nuys Roofing Co today at (866) 321-6172 to schedule your free estimate.
