Trusted Roof Replacement for Woodland Hills Homeowners
A full roof replacement in Woodland Hills typically runs between $14,000 and $32,000 depending on square footage, material choice, and roof pitch. That’s the real number range, not a teaser. Crestview Roofing Co Woodland Hills has been replacing roofs across the west San Fernando Valley since 2000, and every job starts with a written price before any work begins. If your roof is past year 20, showing granule loss in the gutters, or leaking around penetrations, call Dylan Pace and our team at (650) 456-5615. We’ll schedule a free inspection, walk you through what we find with photos, and give you a line-item quote you can hold us to.
Roof Replacement Contractor
Roof Replacement Contractor is the trade term for the licensed professional who tears off your old roof and installs a new one, start to finish. You need one when repairs stop making financial sense: when the decking is compromised, when leaks recur in different spots, or when your shingles are curling and granule-bare. Crestview Roofing Co Woodland Hills handles the full scope: tear-off, decking inspection and replacement, underlayment, flashing, shingles or membrane, and site cleanup. A complete tear-off and replacement in Woodland Hills generally runs $14,000 to $32,000. The number on your written estimate is the number on your final invoice, no change orders.
Decking Assessment First
Before we quote anything, we check what’s underneath. Rotted decking from years of trapped moisture changes the job scope, and we’d rather tell you that before we start than surprise you mid-project. Our written estimates include a decking allowance stated clearly, so you know the worst case in advance.
Manufacturer-Backed Labor
We install materials from GAF, Atlas, and CertainTeed, and we follow their installation specs to the letter so the material warranty stays valid. A roofer who cuts corners on nailing patterns voids your warranty without you knowing it. We document every layer with photos before the shingles go on.
Styles & brands we work with
Asphalt Shingle Roof Replacement
Asphalt Shingle Roof Replacement means removing the existing shingle layer down to the deck and installing a fresh architectural or three-tab shingle system. It’s the most common reroof in Woodland Hills because asphalt shingles handle our hot, dry summers well and cost less than tile or metal. Crestview Roofing Co Woodland Hills installs asphalt shingle systems from GAF, CertainTeed, and Atlas, and a typical single-story asphalt reroof in Woodland Hills runs $14,000 to $22,000. Two-story homes with steep pitches push toward the upper end of the range.
Architectural vs. Three-Tab
Most homeowners we work with choose architectural shingles, sometimes called dimensional shingles. They’re thicker, they last 25 to 30 years versus 15 to 20 for three-tab, and the price difference is usually $1,500 to $3,000 on a standard roof. We’ll show you samples of both and quote both so you can decide with real numbers.
Ventilation Check Included
Asphalt shingles fail early when attic ventilation is poor. In Woodland Hills, where attic temps can hit 130 degrees in August, proper ridge and soffit venting is the difference between a shingle roof that lasts 15 years and one that lasts 30. We inspect and upgrade airflow as part of every shingle replacement we quote.
New Roof Installation
New Roof Installation applies when we’re roofing a structure that never had a roof or when the existing roof is being completely redesigned, like adding a room or converting a flat roof to pitched. It differs from reroofing because we’re building the roof assembly from scratch rather than replacing layers. Crestview Roofing Co Woodland Hills handles new roof installation on additions, ADUs, and full remodels across Woodland Hills. New residential roof installation typically runs $18,000 to $32,000 depending on structural requirements, materials, and the condition of the existing framing.
ADU and Addition Work
We’ve installed more ADU roofs in Woodland Hills than we can count, and we know what city inspectors look for when they walk a new roof. Fire-rated underlayment, proper nailing schedules, and edge metal details get checked every time. We pull the permit when you want us to, schedule the inspection, and stand there while it happens.
Flat-to-Pitch Conversions
Some Woodland Hills homes built in the 1950s and 60s have flat or nearly flat roofs that drain poorly and wear out fast. Converting to a low-slope pitched roof with shingles changes drainage dynamics and adds attic space. We’ll model the structure, quote the framing, and show you the difference in lifespan between the two systems before you commit.
Reroofing
Reroofing is what most people mean when they say they need a new roof: stripping the old shingles or membrane and putting down a new system on the same house. It’s the right move when the roof has reached the end of its service life or when multiple repairs no longer make sense. Crestview Roofing Co Woodland Hills reroofs 40 to 60 Canoga Park and Woodland Hills homes a year. Standard reroofing on a single-story home in this area generally runs $14,000 to $24,000, with material upgrades pushing it higher. We quote it flat and hold it.
Cedar-to-Composite Conversion
A lot of older Woodland Hills homes still have original cedar shake roofs that are dry, splitting, and a fire hazard. We convert these to composite or asphalt systems regularly, and the difference in fire resistance and maintenance is dramatic. The tear-off is more labor-intensive, and we account for that honestly in the estimate.
Two-Layer Tear-Off
If your home has two layers of shingles because a previous owner roofed over the old layer, code requires we tear both off. That adds labor and dump fees, usually $2,000 to $4,000 depending on the roof size. We check for this during the free inspection so it’s in your written price from day one, not sprung on you after the job starts.
Flat Roof Replacement
Flat Roof Replacement is the removal and replacement of a low-slope roofing system, typically built-up asphalt, modified bitumen, or single-ply membrane. Woodland Hills has thousands of flat-roofed homes in neighborhoods like Walnut Acres and the older sections south of Ventura Boulevard. Crestview Roofing Co Woodland Hills replaces flat roofs with materials from GAF and Boral, and our flat roof replacement in Topanga and Woodland Hills on a typical 1,500-square-foot home runs $12,000 to $20,000 depending on the system and the condition of the substrate.
Modified Bitumen vs. TPO
For residential flat roofs, we typically recommend either a modified bitumen system, which is asphalt-based and handles foot traffic well, or a TPO membrane, which reflects heat and can lower cooling costs in Woodland Hills summers. Both have pros and cons. We’ll walk you through both options with prices side by side.
Drainage and Ponding Fixes
Flat roofs fail from standing water, full stop. When we replace a flat roof, we inspect and correct the slope with tapered insulation or deck adjustments so water actually moves toward the drains and scuppers. If your roof ponds after rain, that’s a sign the original slope was inadequate, and a simple re-cover won’t fix it.
Brands We Service
We install and warrant GAF roofing systems, including their Timberline architectural shingle line, which is the most popular choice among Woodland Hills homeowners doing a shingle reroof. We’re certified through GAF’s contractor program and follow their installation specifications on every GAF job, so the material warranty stays fully intact.
We also work regularly with Atlas and CertainTeed shingles. Atlas has a strong architectural line that performs well in high-heat climates like ours, and CertainTeed’s Landmark series is a close competitor to GAF on price and lifespan. If your existing roof is one of these brands and you’re doing a partial replacement or repair, we match color and profile so the new section blends. Whether you have GAF, Atlas, CertainTeed, or any other make, our Woodland Hills team can assess it and give you a straight answer on what it needs.

AfterSigns You Need a Pro Right Now
- Granules in the gutters. Shingle granules look like coarse black sand, and they accumulate in gutters as shingles break down. If you’re seeing granule buildup during gutter cleaning, the shingle surface is failing, and the roof is in its final years. This is when replacement is cheaper than waiting for a leak.
- Daylight through the attic boards. Go into your attic on a sunny day and look at the underside of the decking. If you see pinpoints of light coming through, water gets through the same gaps. This is a sign of failing underlayment or missing shingles, and it means the roof system has already been compromised.
- Curling or cupping shingle edges. Shingles that curl at the corners or cup in the middle have lost the flexibility that keeps them sealed to the roof. In Woodland Hills heat, this happens faster than in coastal communities. Once curling is widespread, the roof can’t protect against wind-driven rain.
- Water stains on ceilings or walls. A brown ring on a ceiling usually means water has found a path through the roof and is traveling along joists or drywall. By the time you see a stain, the leak has been active for weeks. Stains near chimneys, skylights, or plumbing vents point to flashing failures, which are repairable if caught early.
- Soft spots when you walk the roof. If the roof feels spongy underfoot, the decking beneath the shingles has absorbed water and is rotting. Any roof replacement in this condition will need decking replacement too. We find this during regular inspections and factor it into the written quote.
Our Process, Step by Step
- 1
Free roof inspection with photo documentation. One of our uniformed, background-checked technicians comes to your Woodland Hills home, walks the roof, and photographs everything: shingle condition, flashing, penetrations, decking from the attic side, and drainage. You get the photos by text before we leave the driveway.
- 2
Written line-item estimate, delivered before any work starts. We give you a written estimate that breaks down material, labor, tear-off, hauling, decking allowance, and any permits. The number on that page is the number on your invoice. No “we found something” change orders after the job begins.
- 3
Scheduling with a live arrival time you can track. We book the job, confirm the start date, and send you a live trackable arrival time the morning of. You’ll know the technician’s name and see exactly when they pull up, which is the Relay Standard we’ve built the company around.
- 4
Tear-off, decking inspection, and installation. The old roof comes off, and we inspect the exposed decking plank by plank. Rotted sections get replaced at the decking allowance rate quoted in your estimate. Then we install underlayment, flashing, and shingles or membrane to manufacturer specs, photographing each layer.
- 5
Final walkthrough and digital invoice. When the new roof is on and the site is clean, we walk it with you, show you the before-and-after photos, and send a digital invoice by text. Your 365-Day Done Right Promise is in writing and starts that day. If anything fails in the first year, we return and fix it free.
How Much Does Roof Replacement Cost in Woodland Hills?
Here’s what we see on actual Woodland Hills jobs, not national averages:
- Asphalt shingle replacement, single-story, 1,500 sq ft: $14,000 – $20,000
- Asphalt shingle replacement, two-story or steep pitch: $18,000 – $26,000
- Flat roof replacement, 1,500 sq ft: $12,000 – $20,000
- Tile-to-asphalt conversion with full tear-off: $18,000 – $28,000
- Full replacement with rotted decking repair: add $2,000 – $6,000
What moves the price: roof size, pitch (steeper roofs are slower to work on), number of layers being torn off, decking condition, material grade, and whether permits are required. Woodland Hills sits in the city of Los Angeles, and roofing permits run a few hundred dollars depending on scope. We pull them when required and include the fee in your written estimate.
How to avoid overpaying: get at least two written estimates and compare the scope line by line. A lower bid often means a roof-over instead of a tear-off, which violates current code for most situations and hides decking damage. Our free estimate includes scope detail, material specs, and the exact decking allowance. Call (650) 456-5615 for your written quote, and compare it against anyone else’s. We’re fine with that.

Frequently Asked Questions About Roof Replacement in Woodland Hills
Roof replacement is the complete removal of your existing roofing material down to the decking, followed by installation of a new roof system: underlayment, flashing, and shingles or membrane. It’s different from a repair, which addresses isolated damage, and different from a roof-over, which layers new shingles over old ones and violates most current building codes.
Most asphalt shingle replacements in Woodland Hills take 2 to 4 days from tear-off to final cleanup. Flat roof replacements run 3 to 5 days depending on the system and substrate condition. We’ll give you a specific timeline in your written estimate, and weather delays are the only thing that typically moves it.
Most full roof replacements in Woodland Hills run between $14,000 and $32,000, with the typical asphalt shingle reroof landing between $14,000 and $24,000. The exact number depends on roof size, pitch, material, and decking condition. Call (650) 456-5615 for a free written estimate with the full line-item breakdown.
Yes, we install GAF roofing systems and are certified through GAF’s contractor program, so your material warranty stays valid. We also work with Atlas, CertainTeed, and Boral materials. If you have an existing GAF roof that needs replacement, we’ll match the profile so the new system looks seamless with any remaining roof areas.
If a storm or tree damage has compromised your roof, call (650) 456-5615 any time and a live person will answer. We’ll dispatch a technician to tarp the damaged area and assess the scope. For full replacements that result from storm damage, we’ll get you on the schedule as quickly as material availability allows and document everything for your insurance claim.
Every roof replacement we do includes our 365-Day Done Right Promise in writing: if any part of the installation fails within 365 days, we return and correct it at no charge. That includes a free second visit if the repair fails. Material warranties come from the manufacturer, typically 25 to 50 years depending on the product line, and we install to their specs so those warranties stay intact.
Move vehicles out of the driveway and clear anything fragile from walls that share the roofline, since tear-off creates vibration. We protect landscaping with tarps and set up a dump trailer for debris. Our written estimate includes site protection and full cleanup, and we’ll walk the property with you before we start so there are no surprises.
