Free roof inspection with deck photos before we talk money - GAF and Owens Corning certified installation
Fast, Reliable Roofing Company Across Northridge
If you’re looking for a Roofing Company that shows up when it says it will and puts every price in writing before work begins, you’ve found us. Tilehurst Roofing serves homeowners throughout Northridge with roof repair, full roof replacement, roofing inspections, and material options from seven major manufacturers. Call (945) 303-9821 and you’ll reach a live person, day or night. We know Northridge’s post-1994 roof stock better than most because we see it every week: valleys with failing flashing along Corbin Avenue, flat membranes blistering in the valley heat near Tampa Avenue, and ranch homes east of Reseda Boulevard where the decking tells an earthquake story nobody disclosed at closing.
Why Tilehurst Roofing Is Northridge’s Preferred Roofing Company
Homeowners in Northridge call us because they’ve already been burned once by a contractor who no-showed or changed the price at the door. Our crews show up in the window we give, in uniform, background-checked, and we hand you a written price before a single nail is driven. Greg Holloway leads our team, and he insists on the Kingswell Way: say the price before the work, show up when we said we would, leave the place cleaner than we found it, put the guarantee in writing, and come back if anything fails. That last part isn’t a slogan. It’s our 365-Day Done Right Promise, and it’s in writing on every job we do in Northridge.
We answer calls from Northridge homeowners around the clock. Not a voicemail tree. A person. When you call at 9:30 on a Sunday night because a Santa Ana gust tore off a section of ridge cap, you get someone who can dispatch a crew to your street, not a message promising a callback Monday. That’s the standard we operate under, and it’s one reason homeowners from Granada Hills to Reseda keep our number saved.
Roof Coating in Northridge
Roof coating in Northridge is one of the services we perform regularly, though we’re careful about when we recommend it, because a coating is only as good as the substrate beneath it. On a low-pitched commercial or flat residential roof with intact decking and no signs of post-earthquake movement, a properly applied silicone or acrylic coating can extend service life meaningfully. But on many Northridge valley-floor homes, especially those cosmetically patched after 1994, a coating without a tear-off hides cracked sheathing instead of solving it. A typical roof coating job in Northridge runs $2,800 to $5,200 depending on square footage and membrane condition. If inspection reveals suspect decking, we’ll tell you plainly that a coating would be a waste of money until the substrate is corrected.
When coating makes sense and when it doesn’t
Coating makes sense on a flat roof over a detached garage or ADU in Northridge where the decking is sound and the membrane is still bonded. It doesn’t make sense on a 1960s ranch home with original decking that survived the 1994 quake but has been slowly shifting for three decades. We’ll cut a small inspection core before recommending a coating, so you’re not paying for a cosmetic fix that fails inside a year.
How we prepare a Northridge roof for coating
We start with a full surface inspection, then clean the membrane, repair any splits or blisters, address standing water at low points, and only then apply the coating. In Northridge’s 105°F summer weeks, a lighter reflective coating also lowers surface temperature, which can translate to a cooler garage or workshop below. It’s a useful secondary benefit in this part of the San Fernando Valley.
Free Roof Estimate in Northridge
A free roof estimate in Northridge is exactly what it sounds like: we come to your home, inspect the roof, and hand you a written price. No obligation. No pressure. When Greg Holloway’s team looks at your roof, we’re specifically checking for the things most estimators skip in this neighborhood – cracked decking hidden under a post-quake overlay, missing drip edge, step flashings that Santa Ana winds have worked loose over the years, and whether your roof falls under county or city permitting rules for the work you want done. A standard roof replacement estimate visits in Northridge typically runs 45 to 60 minutes, and we walk you through what we found before we leave.
What we inspect during a Northridge estimate
We walk the full perimeter, get on the roof when access allows, check the attic from inside, and note every failure point: granule loss, lifting shingles, rusted flashing, soft decking, ventilation issues. Then we write the scope and price. If your roof includes a detached shop or ADU, we map the lot and note how that affects material access, waste removal, and permitting before we put a number in front of you.
What the written price includes
Our written estimate in Northridge is a fixed price, not a preliminary guess. It includes all materials, labor, debris removal, and any permit fees we already know apply to your job. If we find hidden damage after tear-off that genuinely changes the scope, we stop, show you photos, and get your sign-off before adding a dollar. That’s the only honest way to run a roofing company, and it’s the reason our Northridge customers don’t get the door-price surprise they’ve experienced with other outfits.
Trusted Brands We Service in Northridge
Tilehurst Roofing installs materials from seven manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Northridge’s inland valley heat and Santa Ana exposure, we often recommend GAF architectural shingles with a reinforced nailing strip, or Atlas storm-master shingles for homes that catch the full force of a wind event. We don’t carry just one house brand in the truck and call it a day. If your home wants a tile profile that matches the original mid-century character along Devonshire Street, we can match it. If you want a fortified asphalt system at a mid-range price, we have that too. The product fits the home, not our inventory.
Common Roofing Company Problems We See in Northridge Homes
- Post-1994 cosmetic overlays hiding cracked decking. After the 1994 quake, many Northridge homeowners had a cap sheet or new shingles laid over damaged sheathing because the decking wasn’t visible and the insurance claim had a deadline. Those roofs now need full tear-offs, not reroofs, and the true scope only shows on removal.
- Santa Ana wind damage at ridge caps and eave edges. Periodic Santa Ana events in Northridge apply uplift stress that loosens shingles and step flashings over time. We regularly find entire ridge lines that pop free in one wind event because the original nails were shot short or the cap was sealed incorrectly.
- Thermal cycling from extreme valley heat. With summer afternoons at 105-113°F and no marine layer to soften the sun, Northridge composition shingles crack and lose granules faster than manufacturer lifespan charts predict. Flat roof membranes blister and split. We scope for heavier-grade materials here precisely because the climate is harder on roofs than most of LA.
- Permitting confusion for larger lots with outbuildings. Northridge has a significant number of larger lots with detached garages, workshops, and ADUs. Some fall under county jurisdiction, some under city. Quoting a roof without confirming which authority governs the structure leads to costly surprises. We confirm this before we quote, not after.

FAQs About Roofing Company in Northridge
A full tear-off on a Northridge ranch home costs more because we have to remove the existing roof down to the decking, inspect and likely replace damaged sheathing, and rebuild the roof system correctly rather than layering new shingles over a questionable substrate. Many Northridge homes were cosmetically reroofed in the mid-1990s after the earthquake, which means the original 1950s-1970s decking may have hidden cracks or shifts for decades. A simple reroof would cover that instead of fixing it. Call (945) 303-9821 for a free inspection that tells you which one your home actually needs.
Yes, in some cases. Depending on lot size, building footprint, and whether the structure falls under county or city jurisdiction, a detached shop or ADU roof in Northridge can require a separate permit path, and occasionally different setback and drainage review. We confirm jurisdiction and permitting before quoting so there are no surprises when the inspector walks the property. Call (945) 303-9821 and we’ll check the specifics for your lot.
Northridge heat damages architectural shingles by accelerating granule loss and making the asphalt matrix brittle, which shortens lifespan by several years compared to coastal LA. On flat roofs, 105-113°F afternoon temperatures with direct UV exposure blister and crack membranes. We recommend heavier-grade shingles with proper attic ventilation for Northridge homes, and reflective coatings or reinforced membranes on flats. Call (945) 303-9821 for a free estimate that accounts for your actual exposure.
You should expect a live person on the phone, a scheduled window we actually keep, a thorough inspection of the roof from top and attic, and a written, fixed price before we leave your driveway. The estimate covers all materials, labor, debris removal, and known permit fees. If we find hidden damage after tear-off, we show you photos and get written approval before doing anything beyond the original scope. Call (945) 303-9821 and we’ll put you on the schedule.
A properly installed Northridge roof will hold up to Santa Ana winds when the ridge caps, eave edges, and step flashings are fastened to manufacturer spec with the right nail pattern and sealant. We install all wind-exposed details as if a 60 mph gust is coming next week, because in Northridge it might be. The 365-Day Done Right Promise covers any installation issue for a full year after the job. Call (945) 303-9821 for a free estimate and we’ll walk you through the wind-resistant details on your specific roofline.
