Tilehurst Roofing works across Granada Hills every week. We know the tract ranches off Balboa and Chatsworth, the hillside streets above Rinaldi, and the pocket neighborhoods around Zelzah Avenue where every third house still carries its original roof from the Kennedy administration. Greg Holloway runs our crews, and he’s built the Granada Hills route around one simple reality: most homeowners here have already been burned once by a no-show or a price that changed at the door. We fix that by doing what we say we’ll do.
Why Tilehurst Roofing Is Granada Hills’s Preferred Roofing Company
We’re a member of the Kingswell family of roofing companies, founded in 2000, and every Granada Hills job runs on the same rules: say the price before the work, arrive in the window we promised, put the guarantee in writing before the crew packs up. No exceptions. Greg Holloway personally reviews every Granada Hills estimate before it reaches your hands, and he’s the one you’ll speak with if anything ever falls short. That’s not a line. It’s how the Kingswell Way has operated for 25 years.
The Roofing Company team you’ll work with is background-checked and uniformed. You’ll know exactly who is on your property, and they’ll leave the place cleaner than they found it. Granada Hills customers routinely tell us the thing they noticed first was that we answered the phone. A live person picks up at (945) 303-9821 24 hours a day, seven days a week. Not a voicemail. Not a callback queue. Even on a Sunday night when a Santa Ana wind has peeled back a ridge cap and rain is two hours out.
Every repair carries a written guarantee, delivered before the crew leaves. If that repair fails inside the guarantee period, Tilehurst returns at no charge under our 365-Day Done Right Promise. A full year of documented accountability. For a city where the summer sun bakes roofs past 105°F and the wind through the Santa Susana Pass tests every seam, that guarantee is the floor, not a premium add-on.
Commercial Roofing in Granada Hills
Commercial Roofing in Granada Hills covers the low-slope and flat assemblies on the small office parks along Chatsworth Street, the retail strips off Balboa Boulevard, and the handful of two-story professional buildings near the Northridge border. These are almost always modified bitumen or single-ply TPO systems, and in this city they’re punished harder than anywhere else in the Valley by the summer heat and the wind loads that come straight through the Santa Susana Pass. A commercial flat roof replacement here generally runs $9-$16 per square foot installed, while targeted repairs to flashing, drains, or membrane seams typically fall between $1,200 and $5,500.
Low-Slope Systems That Hold Up to Granada Hills Heat
We recommend white TPO for most Granada Hills commercial roofs. It reflects the inland Valley sun and reduces thermal expansion stress that quietly destroys darker membranes. For older buildings where the deck can’t handle a fully adhered system, a mechanically attached or ballasted approach works better.
Commercial Repair and Maintenance Plans
Drains clog with wind-blown debris from the chaparral slopes above Rinaldi. Scuppers get blocked. Tree limbs from mature eucalyptus plantings scrape against membrane seams. We offer scheduled inspections and maintenance so a small seam split doesn’t become a tenant calling about a ceiling stain on a Monday morning.
Metal Roof Installation in Granada Hills
Metal Roof Installation in Granada Hills is a growing part of our work, mostly on the hillside custom homes off Zelah Avenue and the equestrian properties south of O’Melveny Park where owners are done re-roofing every three or four years. Standing-seam steel and aluminum handle the VHFHSZ requirements beautifully, they shrug off the Santa Ana winds, and they reflect heat instead of absorbing it. Expect a standing-seam metal roof here to run $18-$28 per square foot installed, with the higher end covering heavier gauges and hidden-fastener profiles.
Standing Seam Versus Stone-Coated Steel
Standing seam is the most common choice. It’s sleek, it’s wind-rated, and it needs almost nothing for maintenance. Stone-coated steel gives a more traditional look for owners who don’t want a metal aesthetic, and it still meets Class A fire standards without question.
Metal Roof Retrofit Over Existing Decking
In many Granada Hills cases we can install metal over the existing decking if an underlayment separation layer is added. That saves tear-off labor and keeps the old roof out of a landfill. But when the house north of the Devonshire corridor was last done by a Northridge emergency crew, we insist on opening a few core samples before deciding. You can’t lay a 50-year metal roof on rotted sheathing.
Trusted Brands We Service in Granada Hills
We stock and install materials from seven major manufacturers, and they’re all on the table for your Granada Hills roof. That means GAF architectural shingles for the classic ranch, Atlas for a heavier shingle profile, Tamko for durability at sharp price points, and Boral for the hot, dry conditions that eat cheaper materials alive. Our recommendation matches the home and the specific ridge, slope, and fire-zone requirement at your lot, not whatever happens to be left on our truck. You get genuine choice. Call (945) 303-9821 and we’ll walk you through the trade-offs in plain language, with real numbers for each option.
Common Roofing Company Problems We See in Granada Hills Homes
- The original wood shake is a teardown, not a repair. Granada Hills sits inside LA’s Very High Fire Hazard Severity Zone. The original 1950s-70s shake can’t be patched, recoated, or restored under current code. Every permitted re-roof forces a full tear-off and a Class A assembly. If any contractor quotes a repair without mentioning that, the number will not hold.
- The Northridge-era patch roofs all die at the same time. The 1994 earthquake epicenter sat roughly two miles south of your neighborhood. The emergency repairs done in 1994-96, the flashing, chimney counterflashing, and underlayment, are hitting 30 years old right now, block after block. They look fine from the street. They are not fine underneath.
- The rear shed addition is a failure waiting to happen. So many 1960s-70s Granada Hills ranches have a low-slope shed addition out back, finished with gravel-and-tar built-up roofing. After 50-plus years of extreme diurnal temperature swings, the gravel has migrated into the drains and the membrane is brittle at every seam. It leaks, and the new field roof gets the blame.
- Santa Ana wind damage concentrates at the ridges and starter edges. The wind that funnels through the Santa Susana Pass directly northwest of Granada Hills doesn’t hit flat Valley roofs the same way. It produces uplift pressure on ridge caps and starter-course edges. Roofs installed by crews unfamiliar with that specific pattern fail at those edges first.

Let’s talk real numbers for Granada Hills. A full re-roof on a typical 1,600-2,200 square foot ranch runs $14,000-$26,000 depending on material, decking condition, and whether we’re tearing off one layer or two.

A flat shed-addition membrane replacement runs $3,000-$7,000. Commercial work runs $9-$16 per square foot for replacement, $1,200-$5,500 for repairs.

FAQs About Roofing Company in Granada Hills
No. Granada Hills is inside the City of Los Angeles Very High Fire Hazard Severity Zone, which mandates Class A fire-rated roofing on every permitted re-roof. Wood shake cannot be restored, recoated, or repaired to meet that standard. The only legal path is a full tear-off and replacement with a Class A assembly, typically an asphalt shingle system with special underlayment or a metal roof. Call (945) 303-9821 and we’ll put the exact square footage and material number in writing before you decide anything.
No. You’re seeing the 1994-96 Northridge insurance-era repair roofs hit the end of their useful life simultaneously. The epicenter was roughly two miles south of Granada Hills, and whole blocks got emergency shingles, flashing, and underlayment at the same time. Those materials are now 30 years old. That’s the lifespan. It’s not a fad, and it’s not a sales pitch. Call (945) 303-9821 and we’ll tell you honestly whether your roof is part of that cohort and what’s coming.
You get a written change order before we open a second square. We budget an allowance in the original contract specifically for decking, framing, and waterproofing repairs, because on Granada Hills ranches from the 1950s-70s, we expect to find issues. Soft skip-sheathing at the eaves, rotted fascia, failed valley flashing, brittle built-up membranes out back. None of it is a bad surprise. It’s known risk priced in advance. Call (945) 303-9821 for an inspection that tells you what’s under the shingles before you commit.
Yes. The wind pattern through the pass, directly northwest of Granada Hills, creates concentrated uplift pressure at ridge caps and starter-course edges that flat Valley roofs don’t experience nearly as hard. We add fasteners at the perimeter, install a wider starter strip, and seal the ridge cap to the wind rating for the exposure. It costs a little more on the edges. It’s the difference between a roof that lasts 25 years and one that peels open in the first big Santa Ana event. Call (945) 303-9821 and ask us about the wind-rated installation option.
Those are 1960s-70s Valley builder additions, typically gravel-and-tar built-up roofs. After five decades of extreme heat-to-cold cycles, the gravel migrates to the drains and the membrane goes brittle at every seam. They leak, usually at the seam where the shed roof meets the main house wall. We replace them with modern membrane systems or a matching Class A assembly, and we tie the flashing into the main roof properly. Call (945) 303-9821 for a free inspection that covers the whole roof, including the part out back that everyone forgets.
