Fast, Reliable Roof Installation Across Sherman Oaks
Roof installation in Sherman Oaks runs anywhere from $14,000 to $38,000 depending on the roof type, the square footage, and what the tear-off uncovers. Most single-family homes here, particularly the 1940s to 1960s ranches south of Ventura Boulevard, land between $16,500 and $27,000 for a full replacement with architectural shingles. We’re Crestview Roofing Co Woodland Hills, led by Dylan Pace, and we’ve been installing roofs across Sherman Oaks long enough to know that the quote you get on paper should match the invoice you pay at the end. Call (650) 456-5615 for a written estimate before any work begins.
Sherman Oaks isn’t a one-roof-type town. You’ll see original wood shake on a 1958 ranch on one block and standing seam metal on a stucco-clad addition two streets over. That patchwork means the crew showing up has to actually know how each system ages and fails here, not just how it installs on paper. We do. And we document every step with before-and-after photos, so you see exactly what we saw once the old roof comes off.
Why Crestview Roofing Co Woodland Hills Is Sherman Oaks’s Preferred Roof Installation Company
The reason homeowners around Sherman Oaks keep calling us back is simple: we write the price down before we swing a hammer. A written quote, delivered on paper, before the first bundle of shingles lands on your driveway. No “we found more rot” phone call that doubles the bill without your sign-off. If a tear-off uncovers rotted decking or failed flashing, we show you photos, explain the fix, and get your written approval before we touch it.
Dylan Pace built this company in 2000 on a straightforward promise: total visibility. That means a live trackable arrival time so you know when our background-checked, uniformed crew pulls up to your Sherman Oaks home. It means a digital invoice sent by text. It means every repair carries a 365-Day Done Right Promise in writing. If a covered repair fails within a year, we come back and fix it at no charge. Sherman Oaks homeowners who’ve dealt with the four-hour-window roofer appreciate the difference.
Our crews know the specific pressure points of this neighborhood. We know that the Santa Ana season, running October through March, does more damage in one night than an entire summer of heat. We know the low-slope gable roofs on 1950s ranches south of Ventura Boulevard often hide original decking that’s been silently deteriorating for sixty years. That local knowledge shapes every quote we write for a Sherman Oaks home.
Styles & brands we work with
TPO Roofing Installation in Sherman Oaks
TPO Roofing Installation in Sherman Oaks is the fix we recommend most often for flat and low-slope additions, the kind you see on the back half of so many ranch homes and the post-2000 stucco builds along the hills west of the 405. TPO, or thermoplastic polyolefin, is a single-ply membrane we heat-weld at the seams. The result is a continuous, watertight surface that stands up to standing water and reflects heat effectively, which matters when summers in the Valley push attic temperatures past 130 degrees. A TPO installation on a typical Sherman Oaks addition runs $8,500 to $15,000 depending on square footage, insulation board thickness, and how many penetrations we need to flash.
Wind-Welded Seams for Santa Ana Season
The big concern with TPO on a Sherman Oaks flat roof isn’t rain. It’s wind. A 60 mph gust can catch an improperly welded seam and peel the membrane back like a tuna can lid. We use hot-air welding at every lap and mechanically fasten the membrane at intervals rated for high-wind exposure. After every major Santa Ana event, we get calls from homeowners whose original TPO installers cut corners on fastener spacing, and the failure shows up first along the edges where the wind gets underneath.
When TPO Makes More Sense Than Shingles
If your Sherman Oaks home has a low-slope section, anything under a 3:12 pitch, shingles become a liability. Water doesn’t drain fast enough, and wind-driven rain works its way under the tabs. TPO handles low-slope drainage without relying on gravity alone. On additions and converted flat-roof garages, this is almost always the more durable choice, and it lasts 20 to 25 years when installed correctly.
Shingle Roof in Sherman Oaks
Shingle Roof installation in Sherman Oaks is still the most common full-roof job we do, especially on the 1940s and 1950s ranches that line the blocks south of Ventura Boulevard from Van Nuys Boulevard west to Woodman Avenue. Asphalt composition shingles, typically architectural grade, give you a 25 to 30 year lifespan at a cost that fits most budgets. A full shingle roof installation on a Sherman Oaks single-story ranch runs $14,000 to $24,000, while larger two-story homes or those with steep pitches land closer to $28,000 to $38,000. The final number depends on whether your existing roof is one layer or two, the condition of the decking underneath, and what code upgrades the permit triggers.
High-Wind Nailing Patterns That Actually Hold
The Santa Anas change how we install shingles in Sherman Oaks. Standard installation calls for four nails per shingle. On roofs exposed to the gust patterns that come barreling down through the Sepulveda Pass, we step up to a six-nail high-wind pattern and add starter strip adhesive along the eaves and rakes. The small cost difference is nothing compared to losing a field of shingles at 3 a.m. in a November wind event.
What the Tear-Off Usually Unlocks
On most Sherman Oaks homes getting a shingle roof, the old roof isn’t the only thing coming off. We’re tearing off decades of patchwork: the extra layer of roofing someone nailed on in the 1990s, the rotted decking where chimney flashing has been leaking for years, the eave boards softened by wind-driven rain that got under old drip edge. We price every one of those possibilities into a written allowance before work starts, so the number on your quote doesn’t become a suggestion by day two.
Trusted Brands We Service in Sherman Oaks
We install and repair shingle roofs using manufacturer-backed materials from Owens Corning, Atlas, and Tamko, along with TPO membranes from industry-leading suppliers. We stock common parts for Sherman Oaks jobs so we’re not waiting a week on a shipping delay when your roof is already torn off. For the bulk of our shingle work in Sherman Oaks, Owens Corning Duration architectural shingles are the default recommendation, simply because they hold up better than most under sustained wind loading. We’ll also work with Atlas and Tamko when a homeowner has a specific color or product preference, and every material carries the manufacturer’s warranty in addition to our 365-Day Done Right Promise.
Common Roof Installation Problems We See in Sherman Oaks Homes
- Wind-lifted starter strips and shingle tabs along the ridge. A Santa Ana event over 60 mph will unseal starter strips that weren’t mechanically fastened, and once the leading edge lifts, the underlayment is exposed and every gust after that works more shingles loose. Homes south of Ventura Boulevard near Kester Avenue and Noble Avenue see this pattern every season.
- Rotted decking at chimneys and plumbing penetrations. Failed flashing lets water run down the roof deck for years before any interior stain appears. On original wood shake roofs, which still cover a surprising number of 1950s Sherman Oaks ranches, that water rots the decking straight through.
- Fascia and eave rot from improperly lapped drip edge. Wind-driven rain tracks along the eaves and up under drip edge that was never lapped with ice and water shield. South-facing eaves take the worst of it, and many original ranch homes in Sherman Oaks never had ice and water shield installed at all.
- Patchwork roof systems on additions that don’t match. A 1960 ranch with a 2005 addition often has two different roof systems meeting at one transition. Without proper transition flashing, the seam leaks within a few seasons.

AfterPricing for Roof Installation in Sherman Oaks, CA
Here’s the honest math for Sherman Oaks. A full tear-off and shingle roof installation on a typical single-story ranch runs $14,000 to $24,000. Two-story homes or steep roofs push that to $28,000 to $38,000. TPO on a flat or low-slope addition sits at $8,500 to $15,000. The big variable in Sherman Oaks specifically is what the tear-off reveals: original wood shake homes almost always need at least a few sheets of decking replaced, and many need the full decking but only if the rot is widespread. We write a material allowance into your contract for decking and flashing replacement, and any work beyond that gets priced and approved in writing before we proceed. The number on the page is the number on the invoice. Call (650) 456-5615 for a free, written estimate.

FAQs About Roof Installation in Sherman Oaks
Your quote should include high-wind fastening: six-nail patterns on shingles instead of four, mechanically fastened starter strips, and ice and water shield lapped correctly at the eaves. Any roofer quoting a Sherman Oaks roof without mentioning wind uplift is giving you a generic Southern California price, and you’ll pay for it after the first October gust event. Call (650) 456-5615 for a quote that accounts for the Santa Ana reality.
Almost certainly some decking damage. Original wood shake roofs sit on spaced sheathing, not solid plywood, and where flashing failed at the chimney or plumbing penetrations, the decking rots from the top down. We also find skipped rafters, old wiring stapled to the underside of the decking, and sometimes active termite damage in the eave boards. We’ll show you photos of everything, and any code-required upgrade gets priced and approved in writing before it starts.
Because TPO handles the two things Sherman Oaks flat roofs deal with constantly: standing water after a winter rain and intense summer heat. The heat-welded seams don’t rely on adhesive that breaks down under UV, and the reflective surface keeps attic temperatures down. On low-slope additions where shingles would fail, TPO is the straightforward answer.
One square equals 100 square feet of roof area. So a 20-square roof is roughly 2,000 square feet. When you’re comparing Sherman Oaks quotes, make sure every quote lists the same number of squares, the same shingle grade, and the same decking allowance. We put all of that on our written estimate so you’re comparing actual scope, not marketing language. A free estimate is a phone call away at (650) 456-5615.
Yes, almost always. Most mid-century gable roofs in Sherman Oaks rely on gable-end vents that don’t move enough air through the attic. A continuous ridge vent, combined with soffit intake vents, lowers attic temperatures dramatically, which extends shingle life and cuts cooling costs. If your roof has a permit pulled, code may require ridge ventilation anyway. We’ll confirm what your specific roof needs during the estimate.
On a 1958 ranch just south of Ventura Boulevard, our crew tore off the original wood-shake roof and found the underlying decking had rotted where old flashing had failed at the chimney and plumbing penetrations. We replaced the damaged sheathing, added ice and water shield in the valleys, and installed CertainTeed architectural shingles with a high-wind nailing pattern before finishing with a new ridge vent, then walked the homeowner through the permit-triggered code upgrade for the now-exposed wiring. That’s the job done right in Sherman Oaks.
