We’ve been climbing roofs in the San Fernando Valley since 1984. North Hills is familiar territory - the low-pitched ranches along Plummer Street, the post-war tracts near Nordhoff, the workshop outbuildings behind homes on the neighborhood’s wider lots. We know the 91343 and 91393 ZIP codes well enough to tell you which block is likely to have original 1960s decking and which got the rushed ’94 emergency treatment without anyone looking underneath.
Why Ridgeline Roofing Co. of California Is North Hills’s Preferred Roof Replacement & Installation Company
Homeowners in North Hills call us because we show up when we say we will, and because our technicians are background-checked, uniformed, and trained to document every roof with photos taken from your actual shingles - not a sales pitch from the driveway. Our 90-Day Done Right Promise means if something is not right, we come back and make it right. No paperwork to file, no argument, no runaround.
We are not storm chasers. We are the company that hires local crews, trains apprentices into journeymen, and plans to be here in thirty years. That matters in North Hills, where too many homeowners learned the hard way that the lowest bid from a truck with out-of-state plates does not hold up when the Santa Ana winds return.
Our phones are staffed by a live person 24 hours a day, seven days a week - including the middle of a storm, including Sunday night. When you call (877) 367-1429, someone answers. No voicemail trees, no callback windows, no leaving you stranded while water finds its way through lifted ridge caps.
We have served this valley for over 42 years. Cole Drummond has led Ridgeline Roofing Co. through drought cycles, El Niño winters, and enough re-roofs to know that North Hills presents a specific problem set roofers from outside the valley rarely anticipate.
Our Roof Replacement & Installation Services in North Hills
Full Roof Replacement
Full roof replacement is what North Hills needs most right now, and for reasons specific to this neighborhood. After the 1994 Northridge earthquake, FEMA and insurance funds paid for thousands of emergency re-roofs across North Hills. Those roofs are now hitting 30 years old simultaneously. But the real problem is what lies beneath.
On a ranch-style home near the corner of 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 felt underlayment, and set Owens Corning Duration shingles - all in one trip because the homeowner, a retired contractor who works on his own workshop, insisted on no callbacks. That is the standard we hold for every full replacement in North Hills: tear off to the rafters, inspect what the ’94 crews never had time to inspect, and build back properly.
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 we quote warranty expectations to North Hills homeowners, we are honest about that gap. A 30-year shingle in this climate is not a 30-year shingle by the coast’s standard.
New Construction Roofing
New builds in North Hills are less common than re-roofs, but when they happen - workshop additions, ADUs on larger lots, custom homes replacing quake-damaged originals - we install to current Title 24 energy standards and local wind uplift requirements. Our crews coordinate directly with framers and inspectors to keep schedules tight. We are authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so your architect’s specified material arrives as specified, not substituted.
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 or Torrance.
Our asphalt shingle installations in North Hills typically run $4.50-$7.50 per square foot installed, including tear-off of one layer, deck inspection, new underlayment, and disposal. If we find compromised ’94-era OSB decking, replacement adds $2.00-$4.00 per square foot. We tell you before we cut, not after.
Metal Roofing
Metal roofing makes sense for North Hills homeowners planning to stay put for decades. It reflects Valley heat rather than absorbing it, holds up against Santa Ana wind uplift, and carries warranties that outlast asphalt by a generation. We install standing seam and concealed-fastener systems from Atlas and Tamko, properly flashed at valleys and penetrations. Metal runs higher upfront - typically $12-$18 per square foot installed in North Hills - but the lifecycle math favors it for owners who are not selling soon.
Tile Roofing
Clay and concrete tile suit the Spanish and Mediterranean-influenced homes scattered through North Hills, particularly near the hills. Tile is heavy - often 850-1,000 pounds per square - so we verify that the roof structure can bear the load before quoting. Our tile installations use proper batten spacing, corrosion-resistant fasteners, and valley flashings that account for thermal expansion in extreme heat.
Flat Roofing
Flat and low-slope sections are common on 1960s North Hills ranch additions, carports, and detached workshops. We install torch-down modified bitumen, TPO, and self-adhered cap sheet systems rated for ponding water and UV exposure. Flat roofing in North Hills demands particular attention to parapet flashing and drain placement, because standing water in 110°F heat degrades membrane seams faster than in milder climates. Our flat roof replacements typically run $7.50-$14.00 per square foot depending on access, substrate condition, and insulation requirements.

Common Roof Replacement & Installation Problems We See in North Hills Homes
- Delaminated post-earthquake OSB decking. Roofers in North Hills frequently pull back a 1994-95 overlay and find cracked or delaminated OSB that was never properly inspected. The emergency work was done fast and cheap under disaster conditions. We plan for full deck replacement on roughly half the North Hills tear-offs we bid.
- Santa Ana wind damage to ridge caps and flashing. Wind events funnel through the valley with particular force, lifting aging ridge caps on low-slope rooflines and exposing fastener holes that leak at the first rain. We see this pattern more in North Hills than in neighboring Chatsworth or Canoga Park.
- Premature asphalt shingle granulation and brittleness. North Hills’s 105-110°F summer highs degrade asphalt shingles 30-40% faster than coastal LA ratings assume. A 20-year shingle here often shows significant wear by year 12.
- Failed flat roof seams on workshop and addition roofs. The combination of ponding water and extreme UV exposure on unshaded flat sections causes membrane adhesive failure and seam splitting, particularly on 1960s-era ranch additions with inadequate drainage.

FAQs - Roof Replacement & Installation in North Hills
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 photos from actual North Hills jobs where the visible shingles looked merely old but the deck beneath was failing.
Asphalt shingles in North Hills granulate and become brittle 30-40% faster than identical products installed in coastal Los Angeles. The San Fernando Valley’s trapped heat, with regular summer peaks of 105-110°F, accelerates the oxidation of asphalt binders and causes protective granules to shed prematurely. We quote realistic lifespan expectations and recommend architectural shingles with enhanced UV stabilizers for North Hills installations. For an assessment of your current roof’s condition, call (877) 367-1429 - estimates are free.
Yes - workshop and outbuilding roofs in North Hills face the same UV and wind exposure as the main house, often with less ventilation and more direct sun. We specify cap sheet or TPO systems with higher puncture resistance for workshop traffic, and we use wind-rated fasteners at perimeters where Santa Ana gusts concentrate. If your workshop has a low slope, proper drainage design matters more than material grade alone. We will walk your property and recommend the right system for how you use the building.
It is common enough that we inspect ridge cap fastening as standard practice on every North Hills roof we evaluate. The valley’s topography funnels Santa Ana winds with particular force across low-pitched rooflines, and aging or improperly sealed ridge caps lift first, exposing fastener holes that leak during the next rain. We replace lifted ridge caps with wind-rated shingles and apply manufacturer-specified sealant at all exposed fasteners. If your ridge cap is lifting, the shingles around it are likely nearing end of life - call (877) 367-1429 for a full inspection.
Yes - flat and low-slope sections on 1960s North Hills ranch additions are a significant part of our work. We remove old built-up roofing or modified bitumen, inspect the substrate for water damage (common at drains and parapet walls), and install new TPO, torch-down, or self-adhered cap sheet systems rated for ponding water and extreme UV. We also verify that drainage is adequate, because standing water in 110°F heat degrades membrane seams faster than in cooler climates. Most flat roof replacements on North Hills additions run $7.50-$14.00 per square foot; call (877) 367-1429 for a specific quote.
