Fast, Reliable Roof Replacement Across Westwood
Roof replacement in Westwood is a high-elevation job, not a standard California reroof. At roughly 5,000 feet in the Sierra Nevada, your roof has to shed deep winter snowpack, hold up against ice damming at the eaves, and survive the freeze-thaw cycles that crack flashing and tear at drip edges every spring. We’re Orange County Roofing Co, and we plan for those conditions on every Westwood project we take on. From tear-offs on mid-century cabins to full replacements on ranch homes along the 96137 corridor, one call covers it. Call (866) 942-4187 to schedule a roof inspection or get a written replacement estimate.
Why Orange County Roofing Co Is Westwood’s Preferred Roof Replacement Company
Westwood homeowners don’t need a roofer who treats this town like just another stop on a statewide route. They need a crew that knows what a Sierra snow year does to a roof. Our team has worked through enough Westwood tear-offs to expect the unexpected: rotted decking under old layers, ice-damaged eaves, and framing that hasn’t seen daylight in sixty years. That practical knowledge shapes every estimate we write.
We carry seven major roofing brands, including Owens Corning, IKO, and Atlas, so our recommendation is based on your roof’s snow load and pitch, not on what we happen to stock. Westwood customers consistently tell us the same thing: they valued the straight answer more than the sales pitch. We inspect first, tell you what the roof actually needs, and let the right material win. Kurt Hensley, our owner, sets that standard on every job.

New Roof Installation in Westwood
New roof installation in Westwood means building from the deck up for a roof that will face 400+ inches of snow in a heavy winter. This is the service we recommend when a roof has structural damage beyond repair, when a home addition or new cabin build needs a roof matched to the Sierra snow-load requirements in the 96137 zoning, or when a homeowner wants a clean slate rather than another layer over aging sheathing. A typical new roof installation in Westwood runs $14,000 – $28,000 depending on square footage, pitch, and the material you select.
Decking and Underlayment Built for Snow Load
We don’t skip on the layers you can’t see. On a Westwood new installation, that means full decking inspection, ice and water shield at the eaves and valleys, and underlayment rated for long winter exposure. The wrong underlayment fails quietly, then you find out in April when meltwater shows up on the ceiling.
Ventilation and Snow-Shedding Design
A Westwood roof needs to shed snow or hold it properly, depending on pitch. We plan ridge and eave venting so heat doesn’t melt the underside of the snowpack and create ice dams at the eaves. On steep planes, we install drip edge and flashing that can take repeated snow slides without pulling loose.
Reroofing in Westwood
Reroofing in Westwood usually means tearing off one or two old layers before we can even see what we’re working with. Most homes here are mid-century wood-frame ranches and cabins with low-pitch roofs that have been re-layered at least once. A typical reroof in Westwood runs $9,500 – $18,000, but that number moves when we uncover rot, failed underlayment, or framing that needs reinforcement. That’s exactly why we inspect first and put allowances in writing before the tear-off starts.
The Two-Layer Tear-Off
When a Westwood roof has two old layers, code typically requires removal down to decking. That’s actually a good thing: it’s the only way to see what the old roof has been hiding. Water stains on the decking, soft spots at the eaves, cracked rafter tails. You can’t see any of that from the curb.
What We Find Once the Layers Come Up
On a mid-century ranch off the 96137 grid with two old layers over a low-pitch roof, our crew pulled the tear-off down to decking and found rotted sheathing at the low eaves where the old ice and water shield had failed. The open cavity also exposed undersized framing and knob-and-tube wiring that had been hidden for decades. We priced the decking and framing repairs against the written allowances in the contract, and got the homeowner’s approval in writing before laying new underlayment and GAF architectural shingles with a proper drip edge and ridge vent.
We service Roof Replacement jobs with that same protocol every time: inspect, document, price, approve, then build. If you’re considering a reroof, call (866) 942-4187 before another winter adds more damage.
Trusted Brands We Service in Westwood
We carry Owens Corning, IKO, and Atlas among our seven manufacturer lines, so Westwood homeowners get a real choice in how their roof handles snow and ice. Some want the impact resistance of a heavier Atlas shingle. Others prefer the Owens Corning warranty structure. We order what your roof needs, not what our warehouse wants to move. Because we have access to multiple brands, we can also match the manufacturer’s own warranty tier to your budget without asking you to switch contractors.

AfterCommon Roof Replacement Problems We See in Westwood Homes
- Ice damming at the low eaves. Snowpack builds up, heat from the house melts the underside, and meltwater backs up under the bottom courses during deep-freeze months. Then it leaks inside during the concentrated spring snowmelt, often months after the actual snow fell.
- Hidden rot under re-layered roofs. Most Westwood homes have at least two layers of roofing. The top layer looks fine, but the decking underneath has been trapping moisture for decades. Tear-off is the first time anyone sees it.
- Freeze-thaw damage at valleys and penetrations. Flashing that looks solid in September can be cracked and separated by March. The repeated freeze-thaw cycle works metal loose around chimneys, vents, and valley intersections, and that’s where spring leaks start.
- Snow-shedding damage on steep or metal planes. Snow sliding off a roof plane grabs at the drip edge and fascia as it goes. Over a few seasons, that repeated force pulls fasteners loose and leaves the roof edge vulnerable to wind-driven rain and ice.
Pricing for Roof Replacement in Westwood, CA
Here are honest numbers for the Westwood market. A new roof installation on a typical 1,200 – 1,800 sq ft home runs $14,000 – $28,000. A full reroof with tear-off runs $9,500 – $18,000. Architectural shingles add $2 – $4 per sq ft over basic three-tab. Roof decking replacement, when rot is found, runs $2.50 – $5 per sq ft depending on how much sheathing needs to come out. The single biggest cost variable in Westwood is what the tear-off exposes. That’s why we write allowances into every contract so you’re not blindsided by a change order you never saw coming.

FAQs About Roof Replacement in Westwood
That’s ice damming, and it’s the classic Westwood failure mode. Snow accumulates on the roof, heat from inside melts the bottom layer, and the meltwater runs down to the cold eaves where it refreezes. The ice dam grows and backs water up under the shingles. In spring, that trapped water releases all at once and shows up on your ceiling. The fix is proper ice and water shield at the eaves, adequate ventilation, and sometimes a tear-off to address what the repeated cycles have already damaged. Call (866) 942-4187 and we’ll trace the leak to its source.
The most common findings are rotted decking at the eaves, failed or missing underlayment, undersized rafter framing, and occasionally old knob-and-tube wiring in the open cavity. We’ve also found multiple layers of roofing that were never properly removed. We inspect first, document everything with photos, and price any unexpected repair against written allowances in your contract before we proceed. Nothing gets touched without your written approval.
Yes, often it does. Once the roof is opened to decking and framing, the local building department may require upgrades to meet current snow-load and ventilation requirements. That can include rafter reinforcement, additional collar ties, or improved eave venting. We pull the permits, coordinate the inspections, and make sure the upgrades are priced into your contract before work starts. That’s the honest way to handle it, and it’s the only way we’ll do it.
Snow load changes everything. Westwood roofs must be engineered for the Sierra snowpack weight, which means stronger decking attachment, proper rafter sizing, and ice and water shield at least 6 feet up the eaves and in all valleys. We also install ridge and eave ventilation sized to prevent the warm-roof snowmelt that causes ice dams. A roof spec that works down in the Sacramento Valley will fail up here. We spec for Westwood conditions specifically.
Line up the line items, not just the bottom number. Ask both contractors whether they’re including full tear-off or overlaying, how many feet of ice and water shield they’re installing, whether the decking replacement is included or an allowance, and what the ventilation plan is. Ask who pulls the permit. We give every Westwood homeowner a written line-item quote so you can make that comparison apples-to-apples. Call (866) 942-4187 and we’ll walk you through what to look for.
If your Westwood roof is leaking in the spring, showing signs of ice damming, or just tired after decades of Sierra winters, call (866) 942-4187 to schedule a roof inspection and get a free written estimate. We’ll tell you what the roof actually needs, nothing more.
