Fast, Reliable Roof Replacement Across West Hills
Roof replacement in West Hills runs $14,000 – $28,000 for a typical 1,800 – 2,400 sq ft single-story ranch, with hillside estates and steep-slope tear-offs landing between $28,000 and $45,000 depending on decking repair, layer count, and material class. Those are real numbers from jobs we’ve scoped on Vanowen, Sherman Way, Saticoy, and up in the hills off Valley Circle. If you’re reading this because your original 1960s composition shingles are curling at the eaves or your shake roof is finally giving up after 60 years, call (650) 456-5615 and we’ll walk your roof with you, check the layers, and hand you a written price before any work starts.
Dylan Pace runs our West Hills crews. He’s torn off enough original-tract roofs north of Roscoe to know exactly what’s hiding under that top layer of comp, and he’ll tell you straight what it costs to fix it. Not a guess. A written number, backed by the Relay Visibility Guarantee and the 365-Day Done Right Promise.
Why Crestview Roofing Co Woodland Hills Is West Hills’s Preferred Roof Replacement Company
We’ve been replacing roofs in West Hills since 2000. That’s not a vague claim. It means we’ve watched the original ranch homes on the flats age past their second roof, and we’ve worked the hillside estates where county brush inspectors show up before the shingles even arrive. Our crews know the difference between a 1964 tract house on a slab and a 1980s custom up a flag lot, because we’ve re-roofed both.
West Hills homeowners call us for the same reason you’re reading this: they want a real number, a real schedule, and photo proof the job got done right. Every project starts with a written price. Before any work. No exceptions. You’ll get before-and-after photos, a live trackable arrival time, and a digital invoice texted to your phone when the job closes. That’s the Relay Standard, and it’s on every roof we replace in this city.
When you schedule with us, you get a background-checked, uniformed crew. You’ll know who’s pulling onto your street before they put the truck in park. And if you call at 9pm on a Sunday because a winter storm ripped a cap shingle off, a live person answers. Every time. No voicemail loop, no Monday callback.

New Roof Installation in West Hills
New Roof Installation in West Hills means pulling permits through L.A. County for your lot, not the city, which changes timelines and inspection schedules. If you’re building a new structure, or your existing roof is beyond a reroof and the decking needs a full replacement, this is the job. We install new decking, underlayment, flashing, and the shingle or tile system you choose – all built to current code and the county’s fire-severity requirements.
On a standard West Hills ranch, a new asphalt shingle roof with architectural shingles typically runs $12,000 – $22,000. If you’re in a High Fire Hazard Severity Zone on a hillside lot, you’ll need Class A materials. That’s not an upsell. That’s the county telling you what you can legally install. We quote it correctly the first time.
New Construction and Additions
Building a detached ADU or a shop on your West Hills lot means coordinating roof structure, sheathing, and fire-rated assembly before the inspector walks it. We handle the full roof package: decking, underlayment, flashing, venting, and finish material. We’ll work with your general contractor or run the roofing scope directly.
Roof Decking Replacement
If your tear-off exposes rotten plywood or failed OSB – and on 1960s originals in the tract north of Roscoe, it usually does – you’ll need decking replacement. We replace it by the sheet, and you’ll see exactly how many sheets and the per-sheet price on your written quote. No vague “we’ll see when we get it open” talk.
Reroofing in West Hills
Reroofing in West Hills means tearing off what’s on your roof and installing a new system over the existing structure. The biggest variable on these jobs is how many layers are up there. In the original West Hills tract, we regularly find two layers of composition shingles over the original 1960s wood shake. That’s three roof systems stacked. It changes the dump costs, the labor, and almost always the decking repair line item.
A straight reroof with one layer tear-off on a typical West Hills ranch runs $14,000 – $19,000. Double-layer tear-offs with shake removal add $2,500 – $5,500 depending on how much decking needs replacing and how far the crew has to carry material from the street. Hillside lots off Valley Circle and Saticoy with long carries and limited staging space add another layer of labor cost.
Composition Over Shake Tear-Offs
When we tear off comp over original shake, the shake is often brittle, splitting, and buried under decades of nails. It comes up in pieces, not sheets. Dump fees go up because shake isn’t processed like standard shingle waste. We budget for it, and we show you the line item.
Flashing and Valley Rebuilds
On an older West Hills ranch, the valleys and chimney flashing are usually shot. We don’t just nail new shingles over old flashing. We pull it, inspect the underlayment, add ice and water shield at the valley transitions, and re-flash every penetration. That’s how you stop the winter rain from finding the soffit leaks these 60-year-old homes are known for.
Trusted Brands We Service in West Hills
We install and stand behind the brands we know hold up in West Hills heat and winter rain. GAF, CertainTeed, and Owens Corning asphalt shingles cover most of the ranch homes we replace. For hillside properties and fire-zone work, we lean on Atlas and Boral for Class A rated systems that pass county inspection the first time. We stock common flashing, ridge vent, and underlayment locally, so a reroof on a standard West Hills lot doesn’t stall waiting on parts. If you want a specific manufacturer, we order it and confirm lead times before your written quote goes out.
Common Roof Replacement Problems We See in West Hills Homes
- Hidden double-layer tear-offs north of Roscoe. Many original West Hills homes still have the 1960s wood shake hidden under one or two layers of comp. We confirm the layer count before we quote, not after we start tear-off.
- Rotten decking along the eaves. After 60 years of gutter splash and valley runoff, the plywood at the eaves is often the first thing to fail. We price decking replacement per sheet and show you the count upfront.
- Non-Class A materials on hillside lots. If your property is in the county’s High Fire Hazard Severity Zone and you re-roof with non-Class A shingles, the inspector will red-tag the job. We quote Class A from the start for any hillside address.
- Inadequate valley and edge flashing on low-slope ranch sections. The low-slope transitions on original West Hills ranches collect heavy winter runoff. Without a full ice and water shield, those areas leak into soffits and exterior walls. We address it on every tear-off.

FAQs About Roof Replacement in West Hills
If your hillside property sits in the county’s High Fire Hazard Severity Zone, you must install Class A fire-rated roofing material. That means asphalt shingles from brands like Atlas or Boral with a Class A assembly rating, or tile and concrete systems. You cannot legally put a non-Class A system on that hillside roof. The inspector will catch it, and you’ll pay to redo it. We check your lot’s fire-zone status before we quote, so your written price already reflects compliant materials. Call (650) 456-5615 for a free estimate with the right material specified.
Yes. You can’t reroof over shake, and you shouldn’t reroof over a double layer that’s already failing. The shake is a fire hazard, it’s likely brittle and split, and the decking under it hasn’t been inspected in 60 years. We tear off both, inspect every sheet of decking, replace what’s failing, and install the new system from bare wood up. It costs more up front, but it’s the correct roof, and you won’t be back in five years chasing leaks. Call (650) 456-5615 and we’ll confirm your layer count before anyone touches a shingle.
It can, if you’re adding roof area or changing the eave overhang. More roof = more runoff. On a West Hills lot with a septic system and well, we check the drainage path before we finalize your roof design. If the new eave or valley concentrates water toward the leach field or wellhead, we adjust the gutter and downspout layout to move water away. This is part of our scoping, not an afterthought. Call (650) 456-5615 to talk through your lot’s specific layout.
Yes. The low-slope transitions on those 1960s ranches concentrate winter runoff. Standard felt won’t hold up there. We install a full ice and water shield at valleys, low-slope transitions, and eaves on every West Hills tear-off. It’s a self-adhering membrane that seals around nail penetrations, and it’s the single biggest upgrade you can make to stop leaks on an older ranch. Call (650) 456-5615 to have your roof’s slope and valley layout assessed.
Long carries from the street to a detached structure add labor and waste-hauling cost. If your ADU or shop sits at the back of a deep lot with no vehicle access, we’re hand-carrying materials, setting up a staging area, and moving tear-off waste back to the street in trips. It’s not a surprise line item. We measure the carry distance and factor it into your written quote before you sign anything. Call (650) 456-5615 for a quote that includes access costs, not one that adds them later.
