Trusted Roof Replacement for Ventura Homeowners
A Roof Replacement - Ventura means removing the old roof down to the decking and installing a new system, and it’s a job that affects every part of your home. Coastal salt air off the Pacific shortens roof life here, and many Ventura homes built before 2000 are now due for their second roof. Our crews have replaced hundreds of roofs across Ventura, Oak View, and Port Hueneme, and we handle the job in a way that leaves your floors, garden beds, and driveway the way we found them. Erik Lindgren leads every estimate, and the written price you receive is the number you’ll pay, no surprises. Call (350) 240-5534 to schedule a free estimate.
Key Takeaways:
- Most Ventura roof replacements run $11,000 to $28,000 depending on size, pitch, and material.
- Every job includes shoe covers, drop cloths, and a photographed clean-up before we leave.
- Your written price never changes once you approve it, and the 365-Day Done Right Promise covers the work for a full year.
- We work with GAF, CertainTeed, and Tamko shingles, plus Boral tile for coastal and Mediterranean homes.
Our home page has more on how we protect the inside of your house during a tear-off, and this page walks through everything specific to Roof Replacement in Ventura.
Roof Installation
Roof Installation means putting a completely new roof system on a home that either never had one or needs the old one removed first. In Ventura, this often follows a tear-off of a 20- to 30-year-old asphalt roof, and the cost typically lands between $12,000 and $26,000 for a standard single-story home. We handle the full install: underlayment, flashing, vents, shingles or tile, and a final walkthrough with photos. Your written price covers all of it, down to the last nail.
Tear-Off and Deck Inspection
We strip everything down to the plywood or OSB deck and inspect it before anything new goes on. Rotted decking in Ventura is common near eaves where morning fog sits, and if we find damage, we show you photos and quote the repair before proceeding. Nothing gets covered up without your approval.
Underlayment and Flashing
We install synthetic underlayment that holds up better in coastal moisture than the old felt paper, then replace all pipe boots, valley metal, and step flashing. This is where most leaks actually start, so we don’t reuse old flashing anywhere on the job. New flashing at every penetration is standard on every Birchbark installation, not an add-on.
Styles & brands we work with
Roof Replacement Contractor
A Roof Replacement Contractor is the company you hire to tear off and rebuild a roof, and choosing one carefully in Ventura matters because the right contractor protects both the roof and the inside of your home. Birchbark Roofing Ventura employs background-checked, uniformed technicians who arrive with drop cloths and shoe covers as standard equipment, never as a favor. A typical replacement runs $11,000 to $25,000 depending on squares, pitch, and material. Before we touch anything, you get a line-item written price that doesn’t move.
Written Price Before Any Work
Every Birchbark estimate is delivered as a fixed dollar amount with no allowance for “unforeseen conditions” games. If the deck is rotted, we show you and quote it separately; if it’s not, that line stays zero. Erik Lindgren prices the job himself so the number you sign is real.
Clean-Up Photo Before We Leave
When the last shingle is nailed and the magnet sweep is done, our crew lead photographs the driveway, walkways, and yard. We send you that photo before the crew packs the ladders, so you can see the property was put back the way we found it. That photo is part of the Cedarwell Care Promise on every roof we replace.
Asphalt Shingle Roof Replacement
Asphalt Shingle Roof Replacement is the most common roof replacement we do in Ventura, and it involves removing the old shingle layer and installing a new architectural or three-tab shingle system. Most Ventura homes pay $11,000 to $20,000 for a shingle replacement, with architectural shingles on the higher end because they carry a longer warranty and better wind rating. We install GAF, CertainTeed, and Tamko shingles most often, and we’ll help you pick the right one based on your home’s sun exposure and your budget, not ours.
Architectural vs. Three-Tab
Architectural shingles are thicker, rated for higher wind speeds, and hold their color longer in the Ventura sun. Three-tab shingles cost less upfront but look flatter and typically need replacing sooner. We’ll quote both when they fit your roof, and explain the real lifespan difference in coastal air.
Ventilation and Ridge Caps
A shingle roof is only as good as the air moving under it. We check your attic intake and exhaust and upgrade to ridge vents when your current system doesn’t meet code for the Ventura climate. Attic heat is what curls shingles and bakes out their oils, so this step is part of every shingle replacement we price, not an afterthought.
New Roof Installation
New Roof Installation covers a roof on a brand-new home, an addition, or a full re-deck where new sheathing goes down before the roof itself. The cost in Ventura usually ranges from $13,000 to $28,000 because it often includes new decking and insulation work alongside the shingles or tile. We coordinate with your general contractor if you’re building, and pull permits as needed so the final inspection is clean. Birchbark handles new roof installation from bare trusses to final ridge cap.
New Construction Coordination
If you’re adding a room or building a detached structure in Ventura, we sequence our work with the framers and electricians so the roof goes on as soon as the sheathing passes inspection. We don’t make other trades wait, and we don’t rush ahead before the deck is dry and solid. The permit stays current from start to finish.
Re-Deck and Insulation
When a new roof installation includes decking, we quote the sheathing thickness required by Ventura County code and include it in your written price. We also check what’s under the deck – old batt insulation, loose-fill, or none – and recommend the right upgrade before the roof closes it off. You get one price for the whole scope, roof and deck together.
Reroofing
Reroofing means installing a new roof over the existing one, usually a single layer of shingles still in sound condition, without a full tear-off. In Ventura, reroofing over one existing shingle layer typically saves $2,000 to $8,000 compared to a full tear-off and runs $9,000 to $18,000 depending on roof size. Birchbark will only reroof when code allows it and the existing layer is truly solid; if it’s not, we’ll show you why a tear-off is the better call. We don’t layer roofs over rotted decking to make a bid look cheap.
When Reroofing Works
Reroofing is a fit when your current shingles are past their looks but the deck underneath is dry and stable, and when only one layer exists. Ventura homes with a single layer of 1990s-era shingles on a clean deck can often reroof successfully. We inspect the attic, check for sagging between rafters, and only recommend reroofing when it will honestly last.
When Tear-Off Is the Right Call
If your roof already has two layers, or the existing shingles are curling so badly they’ve exposed the underlayment, a reroof will fail early. We also won’t reroof over a roof with soft decking, no matter where it is in Ventura. In those cases we show you photos from the attic and the roof, quote the tear-off, and let you decide with both numbers in front of you.
Flat Roof Replacement
Flat Roof Replacement is the replacement of a low-slope or flat roofing system, commonly found on Ventura additions, carports, patios, and some mid-century homes. These roofs fail differently than pitched roofs because water doesn’t run off them the same way, and a typical flat roof replacement in Ventura runs $8,000 to $18,000 depending on square footage and the membrane type. We install modified bitumen, TPO, and Boral tile over tapered systems where the home’s architecture calls for it. Every flat roof we replace includes a written price and a water test before we call it done.
Membrane Selection for Coastal Air
Flat roofs in Ventura take more UV than inland roofs, and we usually recommend a white TPO membrane for heat reflectivity or a dual-layer modified bitumen for foot-traffic resistance. We explain the trade-offs of each at your kitchen table and quote them separately. There’s no hidden upcharge for the option you pick.
Drainage and Ponding
Most flat roof failures in Ventura start with ponding water, not leaking seams. We check your existing drains and scuppers, and if the roof is holding water more than 48 hours after rain, we quote the taper system that fixes it as part of the replacement. Water left to stand on a flat roof will find a seam eventually; better to eliminate the pond than chase the leak.
Brands We Service
We’ve installed GAF shingles on hundreds of Ventura homes, and we know their Timberline line well enough to quote it accurately in one visit. GAF’s warranty process is something we handle for you, not something we hand off with a phone number and a pat on the back.
CertainTeed and Tamko both have strong architectural lines, and we have installed enough of each to know their wind ratings and color stability in the Ventura sun. Boral tile is our first recommendation for Spanish and Mediterranean-style homes where concrete or clay tile matches the neighborhood better than shingles. Whether you have one of these brands or any other on your roof, we can repair or replace it, and we’ll tell you honestly if it’s worth saving.

- Granules in your gutters or at downspout outlets. Shingles shed granules as they age, and in Ventura the coastal sun accelerates the breakdown. If you’re seeing a pile of granules after every rain, the shingles are losing their UV protection and the clock is running.
- Daylight visible in the attic. Go up on a sunny morning and look at the roof boards. If you can see light through the decking, water can get through too, and the fix is rarely a patch once the deck is that far gone.
- Curling or lifting shingle edges, especially on the south and west slopes. Ventura’s afternoon sun cooks the shingles on those exposures first. Curling means the shingle’s waterproofing layer is failing and the roof is nearing the end of its service life.
- Water stains on ceilings or walls after a rain, even if the leak doesn’t reappear. A single stain means water found a path in. The leak may only show under specific wind and rain conditions, but the water is still getting behind the roofing and into the insulation and framing.
- Moss or algae streaks that won’t scrub off. Moss holds moisture against the shingle and works its way under the tabs. Once moss is growing in the shingle itself, the roof is compromised and cleaning won’t bring it back.
Our Process, Step by Step
- 1
Estimate and written price. Erik Lindgren walks the roof, checks the attic, and asks how the house is used – kids, pets, work schedules, quiet hours. You get a line-item price in writing before any work starts, and that number does not change unless the deck inspection reveals something new, which we’ll show you in photos.
- 2
Protection of the home’s interior and exterior. Shoe covers go on at the door, drop cloths run through the hall and up to the attic access, and tarps go over garden beds and shrubbery near the drip line. We ask before we move or cover anything, and we use pet-safe products where there’s a choice.
- 3
Tear-off and deck inspection. We strip the old roof and inspect every sheet of decking before the new underlayment goes down. If there’s rot, we photograph it, show you, and quote the repair on the spot – no hidden line items discovered after the fact.
- 4
Installation and daily clean-up. The new roof goes on with new flashing, new underlayment, and new vents. At the end of every workday we magnet-sweep the driveway and walkways and stack materials neatly. You don’t come home to a construction zone.
- 5
Final walkthrough and clean-up photo. When the roof is finished, we walk it with you if you’d like, then photograph the cleaned-up property and send it to you before the crew loads up. That photo is proof, not a promise, and it’s part of the Cedarwell Care Promise on every job.
How Much Does Roof Replacement Cost in Ventura?
A typical Roof Replacement in Oak View and Ventura runs $11,000 to $20,000 for a 1,500- to 2,500-square-foot home, depending on tear-off layers, roof pitch, and whether the deck is sound. Flat roof replacements run $8,000 to $18,000, and full new roof installations with re-decking can reach $28,000. Concrete or Boral tile is higher still, usually $20,000 to $40,000, because the material and the framing requirements are heavier.
What moves your number: roof size in squares, pitch (anything over 6/12 means more safety equipment and slower work), number of layers being torn off, decking repairs, and the material you choose. You avoid overpaying by getting a written, line-item price and by asking whether the quote includes flashing, underlayment, and disposal. Ours always does, because those are part of the roof, not optional add-ons. A free estimate from Birchbark includes the roof inspection, the attic check, and a written price you can keep, no obligation and no follow-up phone harassment.

Frequently Asked Questions About Roof Replacement in Ventura
Roof replacement is the full removal of your existing roofing material down to the wood deck, followed by installation of a new roof system: underlayment, flashing, vents, and shingles or tile. It’s different from a repair, which patches a specific area, and from reroofing, which layers over the old roof.

Call (350) 240-5534 and we’ll inspect yours and tell you honestly which option fits.
Most asphalt shingle replacements in Ventura take two to four days, depending on roof size and weather. Flat roofs and tile roofs can take a little longer, especially if decking repairs are needed.

Every roof replacement carries the 365-Day Done Right Promise: if anything isn’t right within a year of completion, we make it right at no charge. Your shingle or tile material also carries the manufacturer’s warranty, and we handle the paperwork and the claim process for you. The warranty applies to the roof system and the workmanship, not just the material. Erik Lindgren stands behind every roof his crews install.
Move vehicles out of the driveway so we can stage materials and set up ladders, and take down anything fragile on interior walls that share the roofline – vibrations from nailing can travel. We put shoe covers on at the door, drop cloths through the hallway, and tarps over garden beds and shrubs. If the dog needs to stay inside, we coordinate the door schedule with you so no one gets out or gets startled. We ask before we move or touch anything, and we photograph the clean-up before we leave.
