AfterFast, Reliable Roofing Company Across Northridge
A full roof replacement in Northridge typically runs $14,000 to $38,000 depending on square footage, layers to tear off, and whether the decking underneath needs work. Repairs land between $450 and $1,800 for most jobs. We’re Brennan Roofing, and we serve Northridge from Northridge north of CSUN to the acreage lots off Devonshire and Zelzah. The Northridge housing stock is unlike most of the Valley: 1950s and 60s ranch tract homes on old citrus and walnut orchard parcels, many with earthquake patches still up there from 1994. That history changes how a roof is quoted, torn off, and rebuilt here. Call (361) 320-9467 and we’ll send a background-checked, uniformed technician to walk the roof with you and put a written price in your hand before any work starts.
Why Brennan Roofing Is Northridge’s Preferred Roofing Company
Northridge homeowners have a specific frustration with roofers: they get quoted a number, the crew shows up late or not at all, and the price moves once the old roof comes off. We run our Roofing Company operation differently, and it starts with something we call The Garrison Standard. The price goes on paper before any work begins. It does not move at the door. The technicians who arrive are background-checked and in uniform, so you know exactly who is on your roof. And every job is backed by the 365-Day Done Right Promise: if the repair or installation fails within one full year, we come back and make it right at no charge. That guarantee is in writing.
Travis Oakley runs the Northridge crews. He is the point of accountability, and he answers the phone. Not a call center. A live person, 24/7. When a homeowner off Lassen Street calls because a Santa Ana wind lifted a section of ridge cap, the call goes to someone who knows Northridge roofs. That is the whole point of operating under The Garrison Code: the same standard on every job, no matter which technician shows up.

Metal Roof Installation in Northridge
Metal roof installation in Northridge is a growing choice for homeowners tired of replacing asphalt shingles on the same 1950s ranch deck every 15 to 20 years. Standing seam and metal shingle systems handle the Valley heat better than asphalt, and they hold up to Santa Ana wind uplift when installed with the right fastener schedule. A full metal roof on a typical Northridge ranch runs $22,000 to $45,000 depending on the profile, gauge, and whether we are tearing off multiple old layers first. Metal is quieter than most people expect once the underlayment is right, and it reflects heat instead of absorbing it, which matters on a low-pitch roof with a hot attic.
Standing Seam on Low-Pitch Decks
Standing seam panels are the right metal choice for shallow-pitch Northridge roofs. The panels run vertically from eave to ridge with concealed fasteners, so there are no exposed screw heads to back out over time. On a 3:12 or 4:12 ranch roof, we install a high-temperature peel-and-stick underlayment first, then set the panels over it. That underlayment is the real waterproofing layer; the panels are the armor on top.
Metal Shingle Systems
Metal shingles give the look of stone-coated tile or shake without the weight. On older Northridge homes where the original 1960s deck framing was not built for heavy concrete tile, metal shingles solve the weight problem while still reading as a traditional roof. The material cost runs higher than architectural asphalt, but you stop paying for replacement cycles. One roof, one system, for decades.
Residential Roofing in Northridge
Residential roofing in Northridge means working on 1950s and 60s ranch tract homes with shallow gable or hip roofs, most of them over former citrus and walnut acreage. Many of these roofs carry layers from the post-1994 earthquake repair wave: original wood shake, then a patch of mismatched architectural shingles, then sometimes a tile overlay. We tear all of it off down to the decking, because you cannot fix what you cannot see. A full residential replacement on a typical 1,400 to 2,200 square foot Northridge ranch runs $16,000 to $32,000 depending on layers, decking condition, and whether we are re-sheathing. Repairs run $450 to $1,800.
Full Tear-Off and Deck Inspection
We never roof over an existing roof on a Northridge home. The quake-era layers hide decking damage, bad nailing patterns, and missing underlayment. We tear down to the deck, replace any rotted or delaminated sheathing, inspect the rafter tails at the eave, and then build the roof back as one system: drip edge, ice and water shield in the valleys, synthetic underlayment, then the shingle or tile layer. You get a roof, not a patch.
Drainage and Grading on Open Lots
Most Northridge acreage parcels drain to grade, not to a city storm main. That changes the scope on a residential roof. If the roof pitch dumps water next to a foundation with no re-graded swale, the first winter storm pools water against the stem wall. We scope the drainage line item before we quote. Downspouts may need extensions, splash blocks, or a re-graded swale to move water away from the house. That is not an upsell. It is what a roof has to do on a lot without municipal storm drains.
Trusted Brands We Service in Northridge
We install materials from GAF, Atlas, and Tamko, and we carry local stock of the common profiles Northridge homes use most. That means when your ranch roof needs a tile match or a specific shingle color, we are not waiting on a distributor somewhere else in the county. GAF Timberline architectural shingles are our most common Northridge install because they handle the heat and wind of the San Fernando Valley well and carry a strong manufacturer warranty. Atlas and Tamko give us options when a homeowner wants a specific color blend, a heavier shingle, or a particular look on a two-story 1980s home north of Nordhoff.
Common Roofing Company Problems We See in Northridge Homes
- Quake-era patch layers. The 1994 earthquake insurance wave left thousands of Northridge roofs with mismatched shingle patches, skipped underlayment, or a tile overlay on top of damaged decking. Those patches fail first when the next Santa Ana wind hits, and they are the first thing we inspect.
- Undercounted square footage. Roofers quote off the house footprint instead of the actual deck measurement. A roof with three layers from quake repairs has more waste to haul, more labor to tear, and a bigger dumpster line than the lot plan suggests. We measure the deck, not the foundation.
- Drainage that assumes a storm main. On Northridge acreage lots that drain to grade, a roofer who skips the re-grading scope leaves water pooling at the foundation after the first winter storm. That is a roof failure, just not on the shingle surface.
- Santa Ana fastener failures. Architectural shingles nailed too high in the exposure, or with too few fasteners, lift at the edges and ridges during Valley wind events. Baked decking from 100°F summers makes that worse. We document our nailing pattern on every install.

FAQs About Roofing Company in Northridge
Northridge homes carry quake-era layers and often sit on acreage lots with drainage that has to be re-graded, both of which add labor and disposal. Your cousin’s Reseda tract probably had a single-layer tear-off and a city storm main to dump into. Yours likely has multiple layers from post-1994 insurance repairs and drains to grade. The difference is real, and it shows up in the dumpster, labor, and drainage line items. Call (361) 320-9467 and we’ll scope the exact differences on your roof.
Yes. We look for mismatched shingle colors, different shingle profiles in a section, a tile overlay on top of a shingle course, and visible patch lines from the ground or ladder. Then we check the decking underneath. On a half-acre lot off Devonshire Street near Zelzah, we tore off three generations of roof – original 1960 shake, a mismatched architectural patch from a 1994 quake repair, and a tile overlay from a 2003 insurance job – before finding decking nailed with 8d commons and no ice and water shield. We rebuilt it as one GAF Timberline system with a documented nailing pattern. We’ll tell you exactly what is up there and what it costs to fix. Free estimate at (361) 320-9467.
Yes. We pull the county permits for detached structures, ADUs, shops, and outbuildings on Northridge acreage and schedule the inspections. County permitting for an accessory structure roof is different from a city permit for a house roof, and the setbacks for septic and well lines affect where and how a detached structure can be roofed. We scope that before we quote so the permit line item is accurate from day one. Call (361) 320-9467 and we’ll walk your property.
Yes, if the profile is right. Standing seam with concealed fasteners works on a 3:12 or 4:12 pitch, and metal shingles work on shallower pitches when the underlayment is a high-temperature peel-and-stick membrane. Metal reflects heat instead of absorbing it, which matters on a low-pitch roof with a hot Northridge attic. The tradeoff is upfront cost: $22,000 to $45,000 against $14,000 to $19,000 for architectural asphalt. We’ll lay out both numbers in writing and let you choose.
We nail the ridge cap and field shingles to the manufacturer’s high-wind schedule, which for most GAF and Atlas shingles means more fasteners per shingle, set lower in the exposure. Baked decking and under-driven nails are the usual culprits in Valley wind failures. We also inspect the ridge vent and ensure the attic exhaust is working, because a sealed hot attic pressures the ridge from underneath. We document the nailing pattern on every install so you know what went where. For a free wind-damage inspection, call (361) 320-9467.
Why Northridge Roofs Fail Differently Than the Rest of the Valley
Northridge is the only San Fernando Valley community where the 1994 earthquake left a specific re-roofing cycle stamped onto 1950s and 60s tract ranch housing. Thousands of roofs got patched, layered, or fully replaced on insurance timelines in 1994 and 1995, often by crews doing volume work, not careful work. Today those same homes need a second or third roof, and the old quake layers are still up there under whatever came after. Add the orchard-land drainage: wide open lots that drain to grade, not a city storm main. So we plan for layer tear-off and re-grading in the same estimate, because a Northridge roof without proper drainage is a foundation problem waiting for winter rain. No other Valley city has this exact combination.
