Roof Replacement in Granada Hills - Free Roof Inspection, Written Price

Fast, Reliable Roof Replacement Across Granada Hills

A full roof replacement in Granada Hills runs $14,000 to $38,000 for a typical 1,400 to 2,200 square foot ranch home, depending on the pitch, the decking condition underneath, and the Class A assembly your VHFHSZ permit requires. That’s the number most homeowners here actually need before they even think about tear-off versus overlay. Our crews work Granada Hills neighborhoods weekly, from the Balboa corridor to the hillsides off Rinaldi, and we know what the 105-degree summers and Santa Ana winds through the Santa Susana Pass do to a roof that was installed 25 or 30 years ago. Call (945) 303-9821 and we’ll put a written price in your hands before anyone sets a ladder against the house.

Why Tilehurst Roofing Is Granada Hills’s Preferred Roof Replacement Company

Granada Hills homeowners call us after a previous roofer has already let them down. That’s not a marketing line – it’s the actual pattern. The no-show, the price that changed at the door, the repair that failed before the next rain came. When we replace a roof here, the price is written, the crew shows up in the window we gave, and the guarantee is in writing before the last tile is set.

Greg Holloway leads our crews, and the standard is not complicated: show up, say the price out loud, do the work the way the contract says, leave the property cleaner than we found it, and if anything fails, come back under the 365-Day Done Right Promise. A live person answers our phones 24 hours a day, seven days a week. Not a voicemail. Not a callback queue. You call, a person picks up, and that includes evenings and weekends when a leak gets worse instead of better.

We’re a Kingswell family company, founded in 2000, and every Tilehurst Roofing location operates under the same written guarantee. Local crews serve Granada Hills directly, with scheduling coordinated from our Los Angeles office. What that means in practical terms: the roofer who walks your roof knows the Granada Hills permit requirements, knows the fire zone rules, and has already torn off a dozen roofs in your neighborhood this year.

Flat Roof Replacement in Granada Hills

Flat Roof Replacement on a Granada Hills rear shed addition runs $4,500 to $11,000 for a typical 300 to 600 square foot built-up roof, and that number climbs if we find the decking delaminated underneath – which we usually do. Most of these additions went on in the 1960s and 70s, finished with gravel-and-tar built-up membranes that have now thermally cycled through 50-plus years of 105-degree days and cold Valley nights. The gravel migrates to the drains, the membrane goes brittle at every seam, and what looked like a small patch job is actually a full membrane failure.

We inspect before we quote. That means walking the roof, checking the seams, and looking at what the drains are actually doing. The written price you get includes the decking replacement if the inspection shows it’s needed – that’s what a written allowance is for, and we’ll explain it in plain English before you sign anything.

Built-Up Roof Tear-Off for Ranch Additions

When we tear off a Granada Hills built-up roof, we’re often the first crew to open it since it went down. What we find is consistent: water-saturated fiberglass mats, split seams at the parapet walls, and decking that has softened enough to flex under foot. We re-sheet the decking, lay a fresh Class A membrane system, and bring the drains and scuppers back to code.

Low-Slope Membrane Systems

For a low-slope rear addition with a modern single-ply membrane, you’re looking at $4,800 to $9,500 in Granada Hills, depending on whether we need tapered insulation to fix ponding. Ponding is the killer on these roofs – water that sits for days after a rain because the slope was never right in the first place. We fix the slope before we install the membrane, not after.

Roof Installation in Granada Hills

Roof Installation on a new build or full addition in Granada Hills runs $18,000 to $45,000 for a standard single-family home, and the fire zone is non-negotiable: the City of Los Angeles will not issue a permit for anything less than a Class A fire-rated assembly. That rules out wood shake outright, and it means your underlayment, your shingles, and your ridge assembly all need to meet the VHFHSZ standard. We handle the permit process, we pull the permits, and we don’t start framing until the inspection schedule is clear.

The difference between a roof that lasts 15 years and one that lasts 30 in Granada Hills is usually in the details nobody photographs: the drip edge, the starter course, the ice and water shield through the valleys and around every penetration. We install those to manufacturer spec on every job, and we write it into the contract so you can hold us to it.

New Construction and Full Additions

When we’re roofing a new build in Granada Hills, we coordinate with your framer, your electrician, and your inspector. The roof goes on in sequence, not whenever our schedule allows. What that means for you is fewer delays, fewer change orders, and a finished roof that passes inspection the first time.

Class A Assembly for VHFHSZ Compliance

If you’re in the very high fire hazard zone – and most of Granada Hills is – your roof assembly is a life-safety system, not just a roof. We know exactly what the Los Angeles Department of Building and Safety inspector will be looking for on your final inspection, and we build to that spec from the first nail. No surprises at inspection, no eleventh-hour rework, no permit limbo.

Trusted Brands We Service in Granada Hills

We install roofs from GAF, Atlas, and Tamko, and we stock the common lines for Granada Hills jobs so you’re not waiting two weeks on a special order. If you want the fire-rated architectural shingle that matches the tan-and-white palette you see all over the Balboa corridor, we’ll spec it. If you want the heavier Class A assembly with a 50-year manufacturer warranty, we’ll walk you through what that costs here and why it’s worth doing in the fire zone. The product fits the home and the zone, not whatever happens to be on the truck that morning.

Common Roof Replacement Problems We See in Granada Hills Homes

• 1994-era Northridge emergency repairs failing in clusters. A huge share of Granada Hills homes got emergency roof patching in 1994-96, and those repairs are now hitting 30 years old at the same time across whole blocks. Original shake decking underneath often has no ice and water shield at the valleys or penetrations – a leak waiting for the next heavy rain.
• Rear shed additions with dead built-up roofs. The 1960s and 70s ranch homes all over Granada Hills have low-slope rear additions with gravel-and-tar roofs that failed long ago. The gravel migrates, the seams crack, and the decking underneath rots out from thermal cycling.
• Santa Ana wind damage concentrated at ridge caps and edges. Wind funnels through the Santa Susana Pass northwest of Granada Hills and hits ridge caps and starter-course edges with uplift pressure that flat Valley roofs never see. We see architectural shingles pulled loose that were fastened to spec – the spec just wasn’t written for this wind pattern.
• Shingle oxidation from inland Valley heat. Summer temperatures over 105 degrees bake asphalt shingles here far faster than coastal LA homes of the same age. Granules wash off, the mat shows through, and a roof that looked fine at year 15 is done at year 20.
