North Hills sits in a pocket of the Valley where the 1994 Northridge earthquake did its heaviest damage. Thousands of homes here received rushed emergency re-roofing in 1994-1996, and those systems are now hitting their 30-year failure threshold. When we drive to a job near Parthenia Street or along the 405 corridor, we’re not guessing at what we’ll find. We know the housing stock: 1950s-1970s single-story stucco tract homes, low-pitched gable and hip roofs, many carrying double-layered systems that L.A. City code now requires to be fully removed. That history changes how we quote, how we scope, and what we recommend.

Our Specialty Roofing Services in North Hills
Modified Bitumen Roofing
Modified bitumen is our most-recommended system for North Hills’s low-slope roofs, especially on the neighborhood’s 1960s-1970s ranch-style homes where the original tar-and-gravel built-up roofing has aged past recovery. The San Fernando Valley’s heat-island effect pushes summer highs to 103-108°F, far more destructive than coastal L.A. We install GAF Liberty SBS-modified systems with enhanced UV resistance, designed to withstand those repeated thermal cycles without the seam delamination we see on cheaper membranes. A typical modified bitumen installation in North Hills runs $12,000-$18,500 for a 1,800-square-foot home, including full tear-off of any double-layer system.

Built-Up Roofing (BUR)
Built-up roofing was the original standard on North Hills’s post-war tract homes, and we still install and repair these multi-ply systems where the structure can support the weight. Many homes near Nordhoff Street and the 91343 ZIP code retain their original BUR under one or more overlays. When we encounter these, we assess whether the decking can handle a modern equivalent or whether a lighter modified bitumen conversion makes more sense. BUR replacement in North Hills typically ranges $10,500-$16,000, though homes with double-layer removal and decking repair can run higher.

TPO Roofing
TPO has its place on North Hills’s commercial and multi-family low-slope structures, but we’ve learned to be selective. On a 1960s tract home near Parthenia Street and the 405 freeway, we found that a south-facing TPO roof had delaminated at the seams from repeated 105°F afternoons. The homeowners had already gone through two patch repairs, so we recommended a full tear-off of the double-layer system (required by L.A. City code) and installed a new GAF Liberty SBS-modified bitumen roof with enhanced UV resistance. We also replaced the corroded chimney flashing that had been leaking into drywall for years. TPO installation in North Hills generally runs $11,000-$17,500.

EPDM Roofing
EPDM rubber membrane serves North Hills’s flat-roof additions, garage structures, and some mid-century modern homes in the 91393 area. The material handles thermal expansion well, but Santa Ana wind events funneling through valley gaps routinely produce gusts above 50 mph that test every edge flashing and seam. We install EPDM with fully adhered or mechanically fastened systems depending on wind exposure, and we never skip the walkable protection pads that prevent foot-traffic damage during future HVAC or solar service. EPDM projects in North Hills typically cost $9,500-$15,000.

Solar Ready Roofing
North Hills homeowners adding solar need a roof that will outlast the panels. Given the neighborhood’s double-layer code complications and the prevalence of post-1994 lightweight concrete tile that may not support rack loads, we evaluate structural capacity before any solar attachment. Our Specialty Roofing team coordinates with solar installers to ensure flashing integrity at every penetration. Solar-ready re-roofing in North Hills runs $14,000-$24,000 depending on system type and structural upgrades needed.

Green Roofing
Green roofs remain uncommon in North Hills’s single-family stock, but we’ve installed modular systems on a handful of custom homes and accessory dwelling units near the Sepulveda Basin. The primary constraint is structural: those 1950s-1970s tract frames were never engineered for saturated growing media. Where feasible, we specify lightweight extensive systems with drought-tolerant plantings suited to the Valley’s dry summers. Green roof installations start around $22,000 in North Hills and require engineering review.

We stock common membrane rolls, modified bitumen cap sheets, and flashing components locally, so most repairs don’t wait on delivery.

Common Specialty Roofing Problems We See in North Hills Homes
- Corroded post-earthquake galvanized flashings. Roofers working North Hills consistently find that chimney and parapet flashings repaired hastily after the ’94 quake used galvanized metal that has since corroded through. The leaks were hidden for years under successive interior paint layers, so what looks like a minor flashing job frequently reveals rotted sheathing and damaged rafters at the chimney saddle.
- Double-layered asphalt shingle roofs requiring full tear-off. A significant share of North Hills stock received a second roof layer after the ’94 quake. L.A. City code now requires complete removal before any new installation, adding labor and disposal cost that out-of-area contractors sometimes underestimate.
- Santa Ana wind damage to low-slope edge flashings. Fall wind events funneling through the valley gaps produce gusts above 50 mph that lift aging ridge caps and flashings on the neighborhood’s low-slope roofs, especially where original 3-tab shingles have grown brittle from years of 108°F heat.
- Thermal splitting on south- and west-facing slopes. The Valley’s heat-island effect causes accelerated granule loss and thermal splitting that coastal Los Angeles rarely sees. We’ve replaced shingles on North Hills homes that were technically within warranty age but had failed prematurely from pure thermal stress.

FAQs - Specialty Roofing in North Hills
Many North Hills homes received a second roof layer during the rushed post-1994 earthquake repairs, when speed mattered more than long-term planning. L.A. City code now requires full tear-off of any double-layered system before new installation, which adds cost but prevents the structural and ventilation problems that overlays create. If you’re unsure whether your home has one layer or two, we’ll determine that during our free inspection. Call (844) 563-1816 to schedule.
Yes, and this is the most common hidden leak source we find in North Hills. The post-quake repairs often used galvanized metal that corrodes through in 20-30 years, and the slow leaks stay hidden behind interior paint until the drywall softens or mold appears. We recommend a chimney flashing inspection for any North Hills home with original post-1994 repairs. The repair typically runs $850-$2,400 depending on whether sheathing or rafter repair is needed underneath. Call for a free evaluation.
Repair makes sense for isolated cracked tiles or slipped underlayment; replacement is warranted when the lightweight concrete tile installed under insurance pressure is failing systematically, or when the underlying wood structure has shifted from earthquake damage. We evaluate the fastening system, underlayment condition, and structural integrity before recommending either path. Most full replacements on these systems in North Hills run $18,000-$28,000. We’ll give you an honest assessment - call (844) 563-1816.
The San Fernando Valley’s heat-island effect pushes North Hills summer highs to 103-108°F, which accelerates granule loss on asphalt shingles, causes thermal splitting on south- and west-facing slopes, and degrades membrane adhesives on low-slope systems faster than coastal climates. We specify materials with enhanced UV resistance for North Hills installations, and we orient our recommendations around your home’s specific exposure. A seasonal inspection every fall catches heat damage before winter rains exploit it. Call to book our $89 Seasonal Tune-Up.
Yes. The valley gap geometry funnels Santa Ana winds through North Hills at higher velocity than surrounding areas, producing gusts above 50 mph that lift edge flashings and ridge caps on low-slope roofs. Homes with brittle original 3-tab shingles or corroded post-quake flashings are especially vulnerable. We install wind-resistant edge details and inspect attachment points as standard practice on every North Hills job. If you’ve noticed lifted caps or debris accumulation after a wind event, call (844) 563-1816 for a same-day inspection.
