Why North Hills Homes Are Different
North Hills sits immediately adjacent to the epicenter of the 1994 Northridge earthquake, and a large share of its post-WWII tract homes received rushed FEMA- or insurance-funded emergency re-roofs in 1994-1995. Those roofs are now hitting 30 years old simultaneously, often with compromised or unrepaired decking underneath. The San Fernando Valley traps heat, and North Hills regularly sees summer highs of 105-110°F - that heat granulates and brittles asphalt shingles 30-40% faster than the same product would age in coastal Los Angeles. When our crews pull back shingles on a home near Plummer Street or Woodley Avenue, we regularly find cracked or delaminated OSB decking that was never properly inspected.
Roof Repair in North Hills
Roof repair in North Hills typically runs $350-$1,800 depending on scope, with most standard repairs completed in a single visit. Our crew reaches North Hills properties within 45 minutes to an hour, and we carry the materials to finish the job that same day. The 1994-era overlays common here mean we never assume the visible shingle is the whole problem - we inspect what’s beneath before we quote.
Shingle Replacement
North Hills asphalt shingles take a beating no manufacturer brochure fully accounts for. Summer highs of 105-110°F granulate and brittle three-tab and architectural shingles 30-40% faster than identical products age in coastal Los Angeles. We replace failed shingles with lines rated for inland heat, and we always inspect the decking beneath - because in North Hills, the shingle is rarely the whole story. A standard shingle replacement runs $650-$1,200 for one to two squares with standard access.
Leak Repair
Leaks in North Hills homes often trace to two sources: lifted ridge caps from Santa Ana wind events, and compromised flashing on low-slope ranch rooflines that pool water during rare but intense winter rains. Our leak repair starts with water-path tracing, not guesswork. We inspect valleys, vent penetrations, and the chimney-to-roof junctions that failed en masse after rushed 1994-1995 post-quake repairs. Minor leak repair - flashing seal, small shingle patch - typically costs $350-$650.
My North Hills home had a quick roof overlay after the Northridge quake - do I need a tear-off now?
Yes. If your home received a 1994-1995 emergency overlay, the decking beneath was likely never properly inspected and is now reaching critical failure age. We regularly find cracked or delaminated OSB under those overlays that makes any surface repair temporary at best. A full tear-off lets us assess and replace compromised decking, then install a proper roofing system with manufacturer-warrantied materials. Call (877) 367-1429 for a free inspection - we’ll show you exactly what you’re working with. Learn more about our Roof Repair services.
Roof Replacement & Installation in North Hills
A full roof replacement on a typical North Hills ranch home runs $12,500-$22,000 depending on square footage, decking condition, and material choice. Most of our crews complete residential tear-offs in North Hills in two to three days, with asphalt shingle jobs often finished in a single visit when the deck is sound. We plan for full deck replacement on roughly half the North Hills tear-offs we bid, because the 1994-era OSB beneath those overlays was rarely inspected for delamination.
Full Roof Replacement
Full roof replacement is what North Hills needs most right now. After the 1994 Northridge earthquake, FEMA and insurance funds paid for thousands of emergency re-roofs across North Hills, and those roofs are now hitting 30 years old simultaneously. On a ranch-style home near Plummer Street and Cranford Avenue, we found delaminated OSB decking under a 1995 emergency overlay of GAF three-tab shingles. We replaced the entire deck, installed new underlayment, and finished with architectural shingles rated for San Fernando Valley heat - the job ran toward the middle of our $12,500-$22,000 range due to the full deck replacement.
Asphalt Shingle Installation
Asphalt shingles remain the practical choice for most North Hills ranches, but material selection matters more here than in cooler climates. We steer homeowners toward heavier-duty architectural shingles with higher wind ratings and enhanced UV stabilizers. The Santa Ana winds that funnel through the San Fernando Valley lift aging ridge caps and exposed flashing on low-slope rooflines with particular force. A standard three-tab shingle installed to minimum code will not last as long in North Hills as it would in Santa Monica. Our asphalt shingle installations typically fall between $4-$7 per square foot for materials and labor on sound decking.
My North Hills home had a re-roof after the 1994 earthquake. Can I just overlay new shingles?
No - we do not recommend overlays for North Hills homes with post-’94 emergency re-roofs. The OSB decking installed under disaster conditions was rarely inspected for delamination or proper fastening, and covering it again traps moisture and hides structural problems that worsen with each heat cycle. We tear off to the rafters, inspect every sheet, and replace compromised decking before new underlayment goes down. Call (877) 367-1429 and we will show you what your roof is actually built on. See our full Roof Replacement & Installation capabilities.
Specialty Roofing in North Hills
Specialty roofing in North Hills typically costs $8,500-$18,000 for a full TPO or modified bitumen system on a standard ranch home, with most inspections scheduled same-day and repairs started within 48 hours. If you live in the 91343 or 91393 ZIP codes, you know the San Fernando Valley heat doesn’t negotiate. We’ve replaced specialty roofing systems on homes along Nordhoff Street and rebuilt low-slope sections near Sepulveda Basin.
TPO Roofing for Flat and Low-Slope Sections
TPO single-ply membrane is what we install most often on North Hills’s low-pitch ranch roofs, especially on additions, patio covers, and the flat sections common in 1960s-1970s tract designs. A typical TPO installation in North Hills runs $9,500-$14,500 for a 1,500-square-foot area, including tear-off of the old system. We use heat-welded seams that hold against Santa Ana wind uplift, and we specify white or light-gray reflective membranes that drop surface temperatures 30-50 degrees compared to black modified bitumen - which matters enormously when your roof deck is already cooking at 110°F.
Modified Bitumen for Durable Protection
Modified bitumen remains a solid choice for North Hills homeowners who want a torched or self-adhered system with proven track records in high-heat climates. Typical modified bitumen installation in North Hills runs $8,500-$13,000 for standard residential flat areas. We install both APP and SBS formulations, selecting based on your roof’s pitch, drainage pattern, and exposure to wind. The key detail we never skip: proper fastening at the perimeter and curbs, because Santa Ana winds that funnel through the Sepulveda Pass will test every edge seal you’ve got.
Why do many North Hills roofs need full tear-offs instead of overlays?
Because the 1994 Northridge earthquake triggered a wave of rushed emergency re-roofs across North Hills, and the decking beneath those overlays was often damaged, delaminated, or installed wet, never properly inspected. An overlay traps existing moisture and adds weight to compromised OSB. We find this on roughly half the North Hills homes we inspect that have 1994-era work in their history. Call (877) 367-1429 and we’ll check your roof’s specific condition. Explore Specialty Roofing options for your property.
Gutters & Accessories in North Hills
Gutter installation and repair in North Hills typically runs $850-$2,400 for full replacement, with most repairs completed in a single visit and same-day service available for urgent leaks or separations. If your gutters are sagging, overflowing, or pulling away from the fascia, call (877) 367-1429 - a live person answers, day or night. The same post-1994 emergency work that compromised roofs here often skipped fascia inspection and proper hanger spacing, so we always look behind the gutter before we quote.
Gutter Installation
Full gutter replacement in North Hills runs $1,400-$2,400 for a typical ranch-style home, including removal of the old system, fascia inspection, and installation of seamless aluminum gutters with stainless steel hangers. We install GAF and CertainTeed gutter systems sized correctly for your roof’s square footage and pitch - critical on the low-slope ranch roofs that dominate North Hills, where water moves slower and oversizing prevents overflow during sudden Santa Ana downpours. Every installation includes proper slope calculation and hidden hanger spacing engineered for valley wind loads.
Gutter Repair
Most gutter repairs in North Hills fall between $180-$450. We resecure separated gutters, seal leaks at corners and end caps, and replace damaged sections without tearing off the entire system. The most common repair we see: gutters that have sagged because original galvanized hangers have corroded through from thirty years of 105°F summer heat. We replace them with stainless steel or copper-coated hangers that won’t fail the same way. If your gutters were part of a 1994 emergency re-roof, we’ll inspect the fascia behind them - often the real problem was painted over and forgotten.
How does the Northridge earthquake legacy affect my gutters in North Hills?
Many North Hills homes received rushed gutter replacements during 1994-95 emergency repairs, with mismatched materials, loose attachment, and skipped fascia inspection now causing failures thirty years later. The brackets and hangers installed under disaster conditions weren’t spec’d for long-term valley heat exposure, and fascia moisture damage was often painted over rather than repaired. We routinely find that the gutter you see is only part of the problem. Call (877) 367-1429 for a full inspection. View our Gutters & Accessories services.
Emergency & Storm Damage in North Hills
When a Santa Ana wind event tears through the San Fernando Valley and your roof starts leaking at 2 a.m., you need a crew that knows North Hills - not a dispatcher in another state reading from a script. Our trucks reach homes from the 91343 core to the 91393 pocket within 45 minutes during daylight hours, often faster. A live person answers our phones around the clock, and we carry emergency materials to secure your home before the next rain hits.
Emergency Tarp
When wind-driven rain is entering your home, speed matters more than permanence. Our emergency tarp service secures the breach within hours, using methods that protect your interior without causing additional damage to already-compromised decking. In North Hills, we tarp differently than we would in a newer neighborhood. The 1994-era overlays common here cannot always support standard tarp anchoring without pulling free, so we use specialized fastening that distributes load across structural members. A typical emergency tarp in North Hills runs $350-$650 depending on roof pitch, accessibility, and whether the decking beneath can support secure anchoring.
Storm Damage Repair
Storm damage in North Hills rarely presents itself honestly. The low-pitch ranch roofs that dominate this neighborhood often show only minor granule loss or lifted ridge caps while concealing structural deck failure underneath. Our repair process starts with a full photo-documented inspection. We pull back suspect sections to check for the cracked or delaminated OSB that we find in roughly one of every three post-1994 emergency roofs we examine. Targeted storm damage repair - replacing compromised decking sections, matching shingles, and resealing flashing - generally falls between $1,800 and $4,500.
Should I expect higher repair costs for storm damage due to old earthquake-era decking?
Yes, often by $2,000-$5,000 compared to a straightforward shingle replacement on sound decking. When we pull back a 1994-era overlay and find compromised OSB, the job becomes a full tear-off rather than a repair or overlay. This is not upselling; it is the difference between a fix that lasts and one that leaks again in six months. We quote both scenarios when possible, but we will not install new material over a failing substrate. Call (877) 367-1429 for emergency response. Learn about Emergency & Storm Damage protocols.

What North Hills Customers Say
"Added a ridge vent and cleared the blocked soffit vents. The attic temperature dropped noticeably and the upstairs is livable in summer now."
- Simone Grant"Three cracked tiles and one that had slipped. Matched the tile, no color mismatch, half a day of work."
- Darius Prince"The flashing where the roof meets the chimney had never been done right by the original builder. He rebuilt it with proper step flashing instead of running a bead of caulk over it like the last two people did."
- Maurice Boyd
