We work across the 91343 and 91393 ZIP codes weekly, and our crews know the valley-floor heat cycle better than anyone from outside the area.

Call (866) 942-4187 and we’ll come out, open up the problem area, and tell you exactly what you’re dealing with before any money changes hands.
Why Orange County Roofing Co Is North Hills’s Preferred Roof Repair Company
We built our North Hills reputation the way roofers should: by opening up older tract homes, showing the homeowner exactly what we found, and pricing the repair honestly before the first shingle comes off. Our Roof Repair team has walked hundreds of mid-century stucco roofs between Sepulveda Boulevard, Nordhoff Street, and Woodley Avenue, and we know what hides under them. Kurt Hensley, who leads our company, insists on one rule: no surprise line items. If we find hidden decking rot or a code-required ventilation upgrade once the roof is open, we stop, document it, and get written approval before proceeding.
We carry seven major shingle brands so you choose the roof that fits your home and budget, not ours. That brand-neutral position keeps every recommendation honest, whether you’re patching a 1950s three-tab roof or repairing a flat tar-and-gravel apartment building off Rayen Street. Inspection is always a standalone option too, so if you’re buying or selling a North Hills home, you get a clear diagnostic report without any replacement pressure.
Styles & brands we work with






Commercial Roof Repair in North Hills
Commercial Roof Repair in North Hills means working on the dozens of 1960s and 1970s flat and low-slope apartment buildings, small office strips, and storefronts scattered between Van Nuys and the Sepulveda Basin. These buildings share a common problem: tar-and-gravel or foam coatings that bake under valley-floor summer heat until they blister, crack, and let water pond. A commercial patch job on a North Hills flat roof typically runs $800 – $2,400 depending on membrane type, penetration count, and how much UV damage the coating has absorbed.
Flat Roof Patch and Coating Repair
When a flat roof blisters, the coating lifts away from the underlayment, exposes the felt or foam below to direct sun, and that’s when leaks start after the first hot weeks of summer, not in winter. We cut out the blistered section, inspect the decking underneath, and apply a compatible patch with new coating that bonds to the existing membrane. If the roof has multiple old coatings layered on top of each other, we’ll tell you because adding another layer just traps moisture and repeats the failure cycle.
Penetration and Drain Repair on Flat Roofs
Flat-roof leaks in North Hills apartment buildings often start at penetrations: HVAC curbs, plumbing vents, and drain bowls where sealant has dried and cracked under sustained heat. We re-flash and reseal every penetration we find while we’re up there, not just the one you called about. A drain bowl reset on a flat tar roof here usually runs $400 – $900 including labor and new sealant.
Roof Leak Repair in North Hills
Roof Leak Repair in North Hills usually starts with a stain on the ceiling that shows up weeks or months after the actual damage happened. Valley-floor heat dries out flashing sealant slowly, then a February storm pushes water through the gap and the homeowner finally sees the problem. A targeted leak repair on a North Hills home runs $300 – $900 for most flashing, vent boot, and valley fixes. If the leak has been active long enough to rot decking, the price moves up accordingly, and we’ll document every step.
Flashing and Valley Repair
Old flashing on a 1950s tract home is usually metal that’s still sound but surrounded by dried-out mastic. We remove the old sealant, inspect the flashing for rust and pinhole corrosion, and install new flashing material when the old metal is compromised. Valley repairs run $450 – $1,200 in North Hills depending on valley length, existing underlayment condition, and whether we need to replace shingles on both adjoining planes.
Vent Boot and Pipe Jack Replacement
A failed vent boot is the cheapest leak to fix and the most commonly ignored one. The rubber collar cracks under North Hills sun exposure after 10-15 years, and water follows the pipe straight down into the attic. We replace boots with new units and re-seal the surrounding shingles, typically $250 – $450 per penetration.
Trusted Brands We Service in North Hills
We install and repair shingles from Owens Corning, IKO, Atlas, and Tamko, plus three more major manufacturers, so the roof we recommend is the one that fits your North Hills home and budget. For heat-heavy valley roofs, we often point homeowners toward Atlas StormMaster or Owens Corning Duration lines because their granule adhesion and wind ratings hold up under sustained UV and Santa Ana gusts. We stock common colors and profiles locally for faster repair turnaround, so you’re not waiting a week for a bundle of shingles that matches what’s already on your roof. The right material for your roof, backed by the manufacturer’s own warranty.
Common Roof Repair Problems We See in North Hills Homes
- Heat-driven granule loss on asphalt shingles. North Hills summer surface temperatures on a dark shingle roof regularly hit 150-160°F, which bakes away granules faster than coastal LA roofs ever see. Bare spots left by granule loss expose the asphalt mat to UV and start the clock on micro-cracking and leaks.
- Blistered flat and foam coatings. The tar-and-gravel and spray foam roofs on 1960s-70s apartments around Rayen Street and Sepulveda Boulevard blister under sustained valley heat. Once a blister pops, the underlayment is exposed and ponding water works into the structure.
- Dried and cracked flashing sealant. Old mastic around chimneys, skylights, and valley lines hardens and cracks after enough North Hills summers. Winter rain rides the wind through the Sepulveda Basin gap and forces water into those cracks, which is why February often becomes leak discovery month.
- Hidden multiple re-roof layers. The older stucco tract and apartment roofs across North Hills frequently hide two or three re-roof layers over original wood-shingle or felt underlayment. Those layers trap moisture, hide soft decking, and complicate any repair because we can’t know what’s underneath until we open it up.

FAQs About Roof Repair in North Hills
Because the damage did happen last summer. North Hills valley-floor heat dries out flashing sealant and accelerates granule loss all summer long, but it takes a winter storm to force water through those gaps and into your ceiling. The leak you see in February is the symptom; the cause is often months old. That’s why we always inspect for heat damage and dried sealant even when the current complaint is just one leak. Call (866) 942-4187 and we’ll trace the real source, not just patch the stain.
We inspect first, write allowances into the contract for the known risk areas, and price any surprise in writing before we touch it. Older North Hills tract homes often need attic ventilation brought up to current code once a roof is open, especially if you’re repairing decking or adding a re-roof layer. We document what we find, explain the code requirement in plain language, and get your written approval on the added cost before proceeding. No one starts demo on a 1950s roof and knows everything they’ll find. The honest contractor tells you that upfront and builds the process around it.
It depends on blister density, coating thickness, and how many previous repair layers are already on the roof. If blisters are isolated and the underlying membrane is sound, we can cut out the damaged sections and patch them at $500 – $1,800 per repair. If the roof has two or three failed coating layers and blisters cover more than 25-30% of the surface, you’re probably better off with a full tear-off and new membrane. We’ll show you what we see and explain the cost difference between patching and replacing, with no incentive to push you one way or the other. For an exact quote on your building, call (866) 942-4187.
Ask three questions: what happens if you find hidden decking rot or code issues after the work starts, how many re-roof layers you currently have, and whether the quote includes disposal of old material. If a roofer can’t answer those clearly, keep looking. A quote that doesn’t address hidden layers on a 1950s North Hills tract home is a quote that will change. We price allowances for known risks into our contracts, price surprises in writing, and include disposal in every repair estimate.
Both matter, but installation matters more. A poorly installed premium shingle fails faster than a properly installed mid-tier shingle, especially in North Hills heat. That said, some manufacturers do produce shingles with better granule adhesion and wind ratings that give you a measurable edge against valley UV and Santa Ana events. Owens Corning and Atlas both make lines we recommend often for North Hills roofs. Because we carry seven brands, we can recommend honestly based on your specific roof, not on whichever product gives us the highest margin.
