Fast, Reliable Roof Replacement Across Tarzana
Tarzana homeowners face a roofing landscape unlike most of the Valley. Flat-roofed mid-century ranches south of Ventura Blvd sit just minutes from steep hillside estates wrapped in Spanish tile, and neither style tolerates guesswork. Crestview Roofing Co Woodland Hills handles both ends of that spectrum, and we’ve been doing it since 2000. If your roof is nearing the end of its life, call (650) 456-5615 for a written price before any work starts. You’ll get a real number on paper, a live arrival time you can track, and photo documentation of everything we touch.
Replacing a roof in Tarzana isn’t a one-size-fits-all job. The permitting path changes depending on whether you’re on a standard lot or acreage, and flat roofs south of Ventura need different detailing than tile roofs in the hills. That’s exactly why local experience matters. We scope every Tarzana job the same way: inspect, document, price in writing, then execute against that number.
Why Crestview Roofing Co Woodland Hills Is Tarzana’s Preferred Roof Replacement Company
Tarzana homeowners keep calling us back for one reason: the number we quote is the number they pay. No change orders, no “we found something once we tore it off” pricing games. That’s The Relay Standard, and it’s how every job runs. Dylan Pace built this company on a simple promise: a written price before any work begins, before-and-after photos, a live trackable arrival time, and a digital invoice sent by text. If it’s not done right, the Roof Replacement team makes it right, covered in writing for a full year under our 365-Day Done Right Promise.
We know this area well. Our crews work Tarzana regularly, from the ranch homes off Reseda Blvd to the gated hillside streets above Braemar Country Club. The climate here punishes roofs: intense summer UV, Santa Ana gusts, and winter rains that find every weak flashing point on a flat roof. When we quote a Tarzana roof, we quote it for Tarzana conditions. That means high-wind nailing patterns on hillside tile, positive drainage on flat parapet roofs, and decking inspection at every low spot where ponding water has been sitting.
Calls are answered by a live person 24/7. You won’t sit through a voicemail loop on a Sunday after a storm. You’ll get a background-checked, uniformed technician with a real name and a real arrival time. That’s how Tarzana homeowners expect a roofer to work, and it’s how we’ve operated for 25 years.
Styles & brands we work with
Flat Roof Replacement in Tarzana
Flat Roof Replacement in Tarzana is a different animal than shingle work, and the homes south of Ventura Blvd are where we see it most. These 1950s-70s ranch and modern styles carry built-up roofing or modified bitumen that’s now hitting the 25-30 year mark. The first sentence any Tarzana homeowner with a flat roof should know: ponding water is the enemy. Parapet walls trap rainwater after winter storms, and if the roof wasn’t pitched correctly or the scuppers are undersized, that water sits and rots the decking from above. You won’t see it until the ceiling stains appear.
A flat roof replacement in Tarzana typically runs $9 to $14 per square foot for a full tear-off, new decking at problem areas, and a TPO or modified bitumen membrane. A simple 1,200-square-foot ranch roof lands in the $11,000 to $17,000 range. Add tapered insulation if we’re correcting drainage, and you might see that number push toward $20,000. We include all of this in the written quote, item by item, so you know what you’re paying for before we peel off the first layer.
Parapet Wall Detailing
Homes south of Ventura Blvd commonly have parapet walls, the low perimeter walls that extend above the roofline. These need proper through-wall flashing, counterflashing, and sealant detailing at every seam or the roof will leak at the edges before the field membrane ever fails. We strip the old term bar, install fresh metal, and re-seal the entire perimeter as part of every flat roof replacement.
Drainage Correction
Built-up roofs don’t just wear out; they settle. Low spots develop over decades as the substrate compresses, and water finds them. We map the roof surface with a level during inspection, mark every ponding area, and build tapered insulation into the quote so water moves to the scuppers instead of sitting. If your Tarzana flat roof holds water 48 hours after a rain, that’s a drainage problem we fix at replacement, not patch over.
Roof Replacement Contractor in Tarzana
A roof replacement contractor in Tarzana has to be comfortable with two very different jobs on the same street. The flat-roofed mid-century moderns south of Ventura Blvd demand membrane expertise, while the hillside estates above Mulholland need steep-slope skill and high-wind fastening. Crestview Roofing Co Woodland Hills does both. Our team includes crews that specialize in membrane work and crews that specialize in shingle and tile, so the right people show up for your specific roof.
Full shingle replacement on a typical 1,500-square-foot Tarzana home runs $17,000 to $24,000. Architectural shingles land on the higher end of that range, asphalt three-tab on the lower. Architectural shingles cost more up front but last 30-50 years and hold up better against Santa Ana gusts. For hillside homes with tile, the scope often includes re-fastening every tile to high-wind specs, which adds $3 to $5 per square foot depending on tile type and condition.
Asphalt and Architectural Shingle Replacement
Most Tarzana homes built in the 50s through 70s still carry their second or third shingle roof, which means decking underneath may be original. We inspect every sheet of plywood or OSB during tear-off and replace rotted sections at a fixed rate per sheet, disclosed in the written quote. You’ll see photos of the exposed decking before we put anything back over it. That’s The Relay Standard: no surprises, just documentation.
Tile Replacement on Hillside Homes
Tarzana hillside homes get hammered by Santa Ana wind events, and the difference between a roof that survives and one that doesn’t is often the nailing pattern. Code minimum doesn’t cut it on an exposed ridge above Braemar. We spec high-wind fastening, replace cracked or slipped tiles, and re-flash every penetration. The tile itself might be sound, but the underlayment and fasteners are what actually keep water out.
Trusted Brands We Service in Tarzana
We install Owens Corning and IKO shingles, and we stock Atlas and Tamko accessories locally for Tarzana jobs. Using manufacturer-backed materials means the warranty stands up, but the installation is what makes a roof last. Every system we install follows the manufacturer’s published install spec, and we document the procedure with photos so you have a record. No mystery, no shortcuts. If you have a brand preference when you call (650) 456-5615, tell us, and we’ll quote the system you actually want on your roof.

AfterCommon Roof Replacement Problems We See in Tarzana Homes
- Ponding water on flat parapet roofs. South-of-Ventura ranches trap water at the perimeter, and that water rots decking and works into the interior long before you see a shingle fail. We build drainage correction into every flat roof replacement, not as an add-on.
- Santa Ana wind damage on hillside tile. Gusts tear tiles and shingles when nailing patterns don’t meet high-wind specs. On Tarzana hillside homes, we re-fasten every tile and upgrade underlayment to wind-rated material.
- Leaking tie-ins at detached ADUs and workshops. Unpermitted or poorly integrated outbuildings create valleys and flashing gaps where the new roof meets the old. We re-flash every tie-in and add cricket diverters where water concentrates.
- UV-baked shingles failing early. Tarzana’s inland Valley heat accelerates granule loss and shingle brittleness. If your shingles are brittle and shedding granules, you’re looking at replacement, not repair.
Pricing for Roof Replacement in Tarzana, CA
A full shingle roof replacement in Tarzana runs $17,000 to $24,000 on a typical 1,500-square-foot home. Flat roofs range $11,000 to $20,000 depending on membrane type and how much decking and drainage correction the job needs. Tile replacement on hillside homes starts around $28,000 and climbs with complexity. What moves the number: decking condition, underlayment upgrade, parapet detailing, high-wind fastening, and whether permits and inspections require changes to existing framing. We give you a written, itemized price before any work starts, and that number doesn’t change unless you change the scope. Call (650) 456-5615 to schedule your free estimate in Tarzana.

FAQs About Roof Replacement in Tarzana
We strip the parapet wall down to the substrate, install fresh through-wall flashing and counterflashing, then re-seal the entire perimeter with a membrane-compatible product before we touch the field. Parapet flashing failure is the #1 cause of leaks on Tarzana flat roofs, so it’s included in every flat roof replacement we quote. Call (650) 456-5615 for an exact price on your home.
We re-fasten every tile to high-wind uplift specs rather than trusting the original nailing, upgrade the underlayment to a wind-rated synthetic, and re-flash all ridge and hip lines. On exposed hillside homes above Braemar and Mulholland, code minimum is not enough. A wind-rated tile system costs more up front, but it’s the difference between a roof that stays on and one that peppers your neighbor’s yard.
It changes the flashing scope. Every tie-in between structures creates a valley, and valleys leak when the flashing was done poorly or never done at all. We re-flash every tie-in, add crickets where water concentrates, and bring the entire assembly up to current code. The roof replacement scope on the main house doesn’t shrink because of the ADU, but the ADU’s tie-in work gets priced separately and explicitly in your written quote.
Rooftop drainage on an open lot matters because water that runs off the roof has nowhere to hide. We inspect the roof’s slope, scupper placement, and downspout discharge during the initial walk-through, and we include any needed drainage tie-ins in the written price. On flat roofs with parapets, that means tapered insulation and scupper upgrades. On shingle roofs, it means making sure downspouts discharge away from the foundation.
Larger Tarzana acreage parcels fall under county permitting rather than city building code, which can add a plan-check step and trigger review of septic leach field and well setback clearances. If a planned roof change crosses a setback line, the design may need to shift, and you want a contractor who knows that before demolition starts. We handle the permit path and build any required adjustments into the written quote before work begins. Call (650) 456-5615 to schedule your free estimate.
