We’ve been climbing roofs in the San Fernando Valley since 1984, and North Hills presents a specific set of problems most coastal contractors miss. The neighborhood’s 1950s-1970s ranch tracts, many of them hastily re-roofed after the 1994 Northridge earthquake, are now showing simultaneous failures across three decades of patched-together materials. When we inspect a home near Sepulveda Boulevard or along Nordhoff Street, we know to check for what lies beneath - not just what shows from the street.

Our Roof Repair Services in North Hills
Shingle Replacement
North Hills asphalt shingles take a beating no manufacturer brochure fully accounts for. Summer highs of 105-110°F in the San Fernando Valley 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. We recently repaired a detached workshop on a 1960s ranch property near Woodley Avenue and Nordhoff Street. The heavy-duty garage door opener spring had snapped, and the 30-year-old post-quake overlay hid cracked decking. We tore off three layers, replaced 400 square feet of OSB, and installed a full CertainTeed Landmark system with oversized ridge vents - all in one trip to save our client repeated callbacks.

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. When we find decking saturated beneath an otherwise intact shingle field, we tell you exactly why a patch won’t hold and what a proper fix requires.

Flashing Repair
Flashing on North Hills homes was frequently installed fast and cheap under disaster conditions in 1994-1995. Step flashing, counter-flashing, and valley metal that should last 25 years were often bent by hand from stock coil, improperly integrated with underlayment, and left to fail at the worst possible seams. We remove compromised flashing, inspect the adjacent decking for delamination, and install new metalwork that integrates properly with your roofing system - whether that’s GAF WeatherWatch underlayment or a Tamko Heritage shingle field.

Flat Roof Patch
Many 1950s-1970s North Hills ranches include torch-down or modified bitumen sections over garages, additions, or detached workshops. These low-slope areas demand different materials and techniques than pitched shingle roofs. We patch with compatible membranes, verify proper drainage slope, and check the underlying wood deck for moisture damage that torch-down patches alone won’t solve. In North Hills, that deck was often part of the rushed post-quake overlay cycle and may need replacement before any surface repair will hold.

Common Roof Repair Problems We See in North Hills Homes
- Post-quake overlay hides delaminated decking. We regularly pull back 1994-1995 emergency overlays in North Hills to find cracked or water-damaged OSB that was never properly inspected. The shingles look merely old; the deck beneath is the real problem, and an overlay on top of it will fail within months.
- Extreme Valley heat accelerates asphalt granule loss. North Hills summer temperatures of 105-110°F grind asphalt shingles into premature brittlement. A shingle rated for 25 years in Santa Monica may show significant degradation in 15-18 years here.
- Santa Ana winds lift aging ridge caps and flashing. These seasonal events funnel through the San Fernando Valley with particular force, exploiting any loosened edge on low-slope ranch rooflines and creating recurring leak points that temporary patches won’t resolve.
- Inconsistent roof ages across single properties. Post-1994 emergency repairs mean one section of your roof may be 30 years old, another 15, with incompatible underlayment and decking standards between them. Repairs in one area often expose problems in adjacent sections.

FAQs - Roof Repair in North Hills
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 photos from your actual roof, not a generic presentation.
North Hills sits deeper in the San Fernando Valley heat pocket than Chatsworth, with summer highs regularly hitting 105-110°F compared to Chatsworth’s slightly moderated western exposure. That temperature difference granulates and brittles asphalt shingles 30-40% faster than coastal-LA ratings assume. Your neighbor’s identical shingle line may legitimately last years longer. We specify heat-rated materials for North Hills conditions and set realistic warranty expectations based on actual local performance, not manufacturer ideal conditions.
We focus on roofing systems, not garage door mechanical components - though we do encounter these structures frequently on North Hills acreage properties. For heavy-duty opener springs and door hardware, we refer you to a qualified garage door specialist. What we handle is the roof above that workshop: the post-quake overlay, the cracked decking beneath it, and the proper roofing system to protect your equipment long-term. If your detached structure needs both, call us for the roof and we’ll coordinate timing with your door contractor.
Replacing lifted ridge caps is straightforward, but in North Hills it’s rarely the full solution. Santa Ana winds exploit underlying weaknesses - loose nails, degraded underlayment, or decking flex from delaminated OSB. We replace the caps and inspect what’s beneath them. If the deck is sound, it’s a same-day repair. If we find the post-quake damage pattern common here, we’ll show you exactly why a larger fix is needed. Either way, you’ll know before we start. Call (877) 367-1429 - we answer live even during wind events.
Yes, we patch modified bitumen and torch-down sections common to North Hills 1950s-1970s ranch construction. We use compatible membranes, verify drainage slope, and inspect the underlying wood deck for moisture damage. On North Hills homes, that deck was often part of the rushed 1994-1995 overlay cycle and may need replacement before surface patching will hold. We won’t patch over a failing substrate - we’ll tell you what the roof actually needs and price it upfront. Free estimates: (877) 367-1429.
