AfterFast, Reliable Roof Replacement Across Northridge
A full roof replacement in Northridge typically runs between $12,500 and $28,000 for a standard single-family ranch home, with architectural shingles landing in the $14,000-$22,000 range. Most tear-offs take three to five working days once permits clear, and the crews you’ll see working on Reseda Boulevard or near CSUN know the Valley’s heat, wind, and post-quake housing stock because they work in it every week. If you’re staring at a roof that was patched after 1994 and wondering whether it’s finally done, call (945) 303-9821 and we’ll put a written price in your hands before any work starts.
Why Tilehurst Roofing Is Northridge’s Preferred Roof Replacement Company
Tilehurst Roofing is a Kingswell family company, founded in 2000, and the Northridge homeowners who call us tend to have been burned before: a roofer who no-showed, a price that changed at the door, a repair that failed by spring. That’s exactly who we’re built for. Every job starts with a written price. Every repair carries a written guarantee, handed to you before the crew packs up. And if that repair fails inside the guarantee period, we return at no charge under the 365-Day Done Right Promise. Greg Holloway, who leads our crews, has walked more Valley ranch roofs than he can count, and he’ll tell you plainly what a roof needs, what it doesn’t, and what it costs before a single nail comes off.
We answer the phone with a live person 24/7, including weekends. When you call about a Roof Replacement in Northridge, you won’t get a voicemail box or a call center halfway across the country. You’ll get someone who can schedule a walk-through, explain what we’re looking for, and commit to a window we’ll actually keep.
Flat Roof Replacement in Northridge
Flat roof replacement in Northridge runs $9,800 to $18,500 for a typical single-story home, depending on square footage, decking condition, and the membrane system you choose. The Valley’s 105-113°F summers bake flat-roof membranes hard. What ought to last twenty years often fails at twelve or fourteen here, because the sun is relentless, and there’s no marine layer to soften the blow. When we tear off a flat roof in Northridge, we’re usually looking at cracked cap sheet, failed seams at the parapet, or ponding water that’s been silently working its way into the decking.
Full Tear-Off and Decking Repair
On flat roofs, the decking is everything. A patch-over only works if the substrate beneath it is sound, and after 1994, plenty of Northridge flat roofs got new cap sheet laid over decking that had shifted during the quake. We pull the old membrane, inspect every sheet of plywood, and replace what’s compromised before anything new goes down.
Single-Ply and Modified Bitumen Systems
We install TPO, PVC, and modified bitumen systems, and the choice depends on how the roof drains, what’s already there, and how much direct sun the south-facing sections take. We’ll show you the material options and the line-item price for each, so you’re deciding with real numbers, not a salesman’s shrug.
Roof Installation in Northridge
Roof installation in Northridge for new construction or full re-decking runs $14,000 to $30,000 depending on roof complexity, pitch, and the material you choose, whether that’s dimensional asphalt shingles or a standing seam profile. New construction in Northridge means building to current Title 24 energy standards and wind-uplift requirements that didn’t exist when these 1950s and 1960s ranch homes went up. That difference shows up in nailing patterns, underlayment specs, and the way we tie the roof into the wall assembly.
New Construction Roofing Packages
When a Northridge homeowner is adding a room, rebuilding after the quake damage finally caught up, or doing a full gut remodel, the roof install has to coordinate with framing, electrical, and insulation. We work directly with your general contractor or act as the roofing lead if you’re managing the build yourself.
Asphalt and Architectural Shingle Installation
We install GAF, CertainTeed, Owens Corning, and IKO shingle lines, among others, so the product fits the home, not whatever happens to be on the truck that morning. For most Northridge ranch homes, an architectural shingle with a 130 mph wind rating is the right call, because when the Santa Anas come down the pass, the ridge caps and eave edges take a beating that coastal LA roofs never see.
Trusted Brands We Service in Northridge
We stock and install materials from Atlas, Tamko, Boral, and GAF, along with three other major manufacturers, because Northridge homeowners deserve a genuine choice, not a single house brand pushed on every job. Atlas and Tamko both make architectural shingles that hold up well under Valley UV exposure, and Boral’s tile profiles are a fit for the higher-end Northridge homes south of Devonshire where clay and concrete tile were common on original builds. We can walk you through each option, with pricing, before you commit to anything.
Common Roof Replacement Problems We See in Northridge Homes
- Post-1994 cosmetic patches over cracked decking. The quake cracked and shifted roof decking all over Northridge, and many “repairs” done in the years after were just new shingles or cap sheet nailed over the damage. The roof looks fine from the street, but a full tear-off reveals the truth.
- UV-cooked composition shingles. The San Fernando Valley routinely hits 105°F or higher, and shingles that should last 25 years in a coastal climate will granulate and crack at 14 or 15 in Northridge. We see this constantly on the original roofs of homes built in the 1960s.
- Santa Ana wind damage at the eaves and ridges. Ridge caps, drip edge, and step flashing take the worst of the Santa Ana wind events. Once a ridge cap lifts, water finds the underlayment, and the roof is compromised even if no shingles are missing.
- Valley framing issues on low-pitch ranch homes. Many Northridge ranch homes were built with framing that was code-compliant in 1962, but undersized by today’s standards, especially at valleys where water collects. A proper replacement often means sistering or replacing rafters before new decking goes down.

FAQs About Roof Replacement in Northridge
A quote climbs when the tear-off reveals damage that wasn’t visible from the outside, and in Northridge that damage is usually cracked or shifted decking from the 1994 earthquake. Many post-quake roofs were cosmetic patches: new shingles or cap sheet over decking that was never properly repaired. We handle this differently. Before we start, we inspect the roof, and we write allowances into the contract for the likely decking repair. Any surprise is priced and approved in writing before we proceed. Call (945) 303-9821 and we’ll walk you through exactly how that works on your roof.
You don’t, unless someone has opened it up. A roof installed after 1994 might be a genuine full replacement, or it might be a cosmetic overlay: new shingles over decking that was cracked and shifted during the quake. The only way to know is a tear-off or a targeted inspection that looks at the decking from the attic side. We regularly find homes marketed as having a “newer roof” that have original 1960s decking underneath, never repaired. That’s the hidden substrate damage you hear about when a contractor opens a wall.
Yes, but only if the nailing pattern, underlayment, and material are all rated for it, and the decking is sound enough to hold the fasteners. A 130 mph rating isn’t a sticker, it’s a construction specification. On homes near Northridge Park, where the Santa Anas come through with real force, we set shingles to a 130 mph nailing pattern and verify the decking will actually hold. If the decking won’t, we replace it. Call (945) 303-9821 and we’ll tell you what your roof can honestly earn.
On a typical Northridge ranch home from the 1960s, we find outdated wiring, undersized or damaged framing at the valleys, failed waterproofing at the penetrations, and code upgrades that a permit triggers once the roof is open. That last part matters: once you do a full tear-off, Title 24 and current building code apply, which may mean adding insulation, ice and water shield at the eaves, or re-flashing every penetration to modern standards. We plan for those upgrades in the original quote, so they don’t come as a surprise.
It does. Most shingle manufacturers rate their products for a 20-30 year lifespan, but those numbers assume a temperate climate. Northridge records summer temperatures over 105°F regularly, and that sustained UV and thermal cycling degrades composition shingles and flat-roof membranes well below manufacturer estimates. A roof that should last 25 years in a coastal neighborhood might give you 14 or 15 in the Valley. Call (945) 303-9821 and we’ll give you an honest read on how much life your roof has left.
