Fast, Reliable Roof Installation Across Woodland Hills
A new roof in Woodland Hills typically runs $14,000 to $32,000 for a standard asphalt shingle installation on a 2,000-square-foot home, with premium systems like clay tile or standing seam metal running $28,000 to $65,000. Most full tear-off and replacement jobs take 3 to 7 working days once materials land on site, though acreage properties with detached structures can stretch to two weeks. We know this market because we work it every week. Call (341) 217-2677 and we’ll send someone who knows the difference between a Calabasas-style gated build and a 1960s ranch off Valley Circle Boulevard.
Woodland Hills isn’t one kind of roof. It’s a patchwork of mid-century ranches behind Topanga Canyon Boulevard, hillside terraces south of Ventura Boulevard, and newer builds on roomy lots up near West Hills. Each one demands a different underlayment, a different flashing approach, and a different schedule. That’s why we send a real person to walk your roof before any number goes in writing.
Why Mercer Roofing Co Woodland Hills Is Woodland Hills’s Preferred Roof Installation Company
The thing that sets Woodland Hills homeowners on edge, in our experience, isn’t the roofing itself. It’s the doorbell. Who is this person standing on my porch? Are they really who they say? We solve that before the truck ever leaves the yard. Every Mercer Roofing technician’s name and photo arrives by text before the visit. When they knock, they’re in a clean uniform, and they hand over a photo ID badge. That’s the Threshold Standard, and it’s non-negotiable on every job we run in Woodland Hills.
Mercer Roofing was founded in 2000 as part of the Threshold Group family of home-service companies. Our Woodland Hills location is independently owned and operated under the Threshold Verified framework, which means background-checked, identity-verified crews on every dispatch. Grant Whitlock, our lead here, has walked roofs from the flats of Canoga Park to the ridgelines above Topanga. He’ll tell you straight: the heat on a south-facing slope in August is a different animal, and it changes how we spec decking.
Customers across Woodland Hills, from Warner Center out to Hidden Hills-adjacent estates, tell us the same thing: the written price is what made them call. Not a ballpark. Not a “we’ll see when we get up there.” A line-item price on paper before a single nail goes down. That’s how we operate, and it’s why people who get three bids usually end up here.
Styles & brands we work with
TPO Roofing Installation in Woodland Hills
TPO Roofing Installation in Woodland Hills is the work we recommend most often for the flat and low-slope sections on mid-century ranch homes and modern additions where heat is the enemy. TPO is a heat-reflective single-ply membrane that gets heat-welded at the seams, and on a roof that bakes at 110°F through August, that matters. A bonded seam means no adhesive to dry out and curl under UV assault. We see this all over the flats north of Ventura Boulevard and across the open-lot builds near El Camino Real High School.
Homeowners on larger lots ask for TPO when they’re re-roofing a detached ADU, a workshop, or a garage that the main house doesn’t cover. The membrane handles standing water better than shingles ever will, which matters on open lots where drainage moves slower. A typical TPO installation in Woodland Hills runs $9,000 to $18,000 depending on square footage, insulation board needs, and how much decking has to come up first.
Heat-Welded Seams and the Woodland Hills Summer
The seams are where cheap membrane roofs fail. We heat-weld ours, which creates a single continuous surface that won’t peel apart when the Santa Anas blow. On a flat roof in the Valley, that’s the difference between a 12-year roof and one that makes it 25.
When We Replace Decking Under TPO
Older Woodland Hills homes often have plywood decking that’s been cooking under black roofing for decades. If the deck gives when we walk it, or you can see delamination, we write the replacement into your quote. You’ll see it on the line item, in dollars, before we start.
Shingle Roof in Woodland Hills
Shingle Roof work in Woodland Hills is the bread and butter of what we do, but the heat changes how we do it. Asphalt shingles on a Woodland Hills roof take more UV punishment in a year than a coastal roof takes in three. Granule loss starts early, sealant strips bake out, and by year 12 or 14 on a cheap install, the shingles are splitting. So we spec heavier. We push reinforced decking on south and west exposures, and we recommend heat-reflective shingle lines from Atlas and IKO that are built to take the Valley sun without curling at the edges.
A full shingle roof installation in Woodland Hills runs $14,000 to $32,000 for a typical 2,000 to 2,800 square-foot home, tear-off included. If you’re on a hillside lot with a steep pitch south of Ventura Boulevard, expect the upper end. Steep roofs mean slower work, more safety gear, and more waste. On acreage, a detached garage or ADU shingle job adds $6,000 to $12,000 depending on size. We’ll put all of it in writing before any work starts.
Heat-Reflective Shingle Lines That Survive the Valley
We install Atlas Pinnacle and IKO Cambridge lines more than any other for Woodland Hills homes. Both carry high solar reflectivity ratings, which keeps attic temperatures down and takes pressure off your shingle sealant. It’s a small material upgrade that buys years on a Valley roof.
Steep Hillside Installations Call for Different Decking
On slopes south of Ventura Boulevard, we routinely see decking that’s been flexing under clay tile for decades. We check every sheet before we quote. If the plywood has turned to sponge from one too many hidden leaks, you’ll know it from the written estimate, not from a surprise call at noon on day three.
Trusted Brands We Service in Woodland Hills
We install and repair roofs using manufacturer-recognized shingle brands including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Woodland Hills specifically, we stock and work most with Atlas and IKO shingle lines for heat reflection, plus Boral clay tile for the hillside homes where the Santa Anas demand a heavier product. That means when you need a re-coat, a tile replacement, or a shingle section patched after a wind event, we’re not waiting two weeks on a supplier. We source local and we keep the common materials moving. Grant Whitlock specs every system himself before the quote goes out.

AfterCommon Roof Installation Problems We See in Woodland Hills Homes
- Heat-cracked asphalt shingles under 110°F sun: The Valley’s summer is relentless, and shingles that were fine in year eight are cracking and curling by year twelve. We replace them with heat-reflective lines rated for high UV exposure, and we reinforce the decking underneath so the next roof doesn’t die young.
- Shifted or cracked clay tile after Santa Anas: On hillsides south of Ventura Boulevard, wind gusts after a heat wave expand the tiles and then shove them around. Homeowners often don’t know there’s a leak until the first winter rain soaks through the ceiling. We check tile alignment and flashing on every estimate in these areas.
- Blistered seams on low-slope membrane roofs: Mid-century ranch homes with flat sections trap heat, and a cheap membrane with adhesive seams will blister and split under intense UV. We recommend heat-welded TPO for these sections and quote it separately from the shingle work.
- Weak decking under an aging roof: On open-lot and hillside homes alike, decades of hidden leaks can soften the plywood deck. We catch it during the walkthrough, not mid-install, and it’s always in the written price before day one.
Pricing for Roof Installation in Woodland Hills, CA
A standard asphalt shingle roof installation in Woodland Hills runs $14,000 to $32,000 for a 2,000 to 2,800 square-foot home. Clay tile or Boral systems on hillside homes push that to $28,000 to $65,000. TPO on flat or low-slope sections adds $9,000 to $18,000 depending on area. The variables that move your number are decking condition, roof pitch, number of penetrations, and whether you’re on the flats or up in the hills where cranes and safety gear become necessary. A detached ADU or workshop roof runs $6,000 to $12,000 extra, and it’s often cheaper to do both at once. Call (341) 217-2677 and we’ll walk the property, take measurements, and hand you a written line-item price. No charge for the estimate.

FAQs About Roof Installation in Woodland Hills
Acreage builds in Woodland Hills run higher because of material hauling, equipment access, and the extra square footage that comes with a main house plus outbuildings. A typical sloped-lot home might run $20,000 to $32,000 for shingles, but once you add a detached garage, an ADU, or a workshop, the total can reach $40,000 to $55,000. The good news: combining structures on one permit and one material delivery saves you real money versus doing them separately. Call (341) 217-2677 and ask Grant to walk the whole property with you and quote it as one job.
Yes, and we recommend it. When you’re already paying for material delivery, equipment access, and permit time, folding the ADU or workshop roof into the same scope keeps the per-square-foot cost lower. Most Woodland Hills acreage owners choose TPO for detached flat-roof structures and shingles or tile for the main house. We’ll line-item each structure separately on your written estimate so you can see exactly what each piece costs.
We treat the Valley sun as a design problem, not an afterthought. That means heat-reflective shingle lines from Atlas or IKO on most homes, reinforced decking on south and west exposures, and heat-welded TPO on flat sections instead of adhesive-seam membranes. On clay tile roofs, we upgrade the underlayment so that even if a tile shifts in a Santa Ana event, the roof stays waterproof. The heat is why we spec materials the way we do in Woodland Hills specifically.
Sometimes it’s a tile replacement and new flashing. Often, though, cracked tiles on a Woodland Hills hillside mean the underlayment beneath has been exposed and aging, and a full installation is the honest fix. We’ll walk the roof and tell you which it is. On a hillside lot south of Ventura Boulevard, our crew recently replaced a cracked clay tile system after a wind event with Boral tile, reinforced decking, custom flashing at every valley and penetration, and upgraded underlayment. That’s the standard we’d apply to your house. Call (341) 217-2677 and we’ll give you a straight answer in writing.
On an open lot, water moves differently. We check slope direction, where gutters will discharge, and how runoff interacts with septic lines and well setbacks that county permitting requires us to respect. If the grade slopes toward a structure or a leach field, we’ll flag it before we quote so the roof doesn’t create a drainage problem you have to fix later. This is standard for us on Woodland Hills acreage, not a change order waiting to happen.
