Fast, Reliable Roof Replacement Across Westwood
Roof replacement in Westwood typically runs $9,500 – $16,200 for a standard single-story home with architectural shingles, with most jobs finished in 3 – 5 working days once decking condition is confirmed. That number tracks closer to $12,000 – $21,000 when we’re replacing rotted decking and adding ice and water shield on a low-pitch mill-era roof. If you’re weighing a tear-off versus another patch job on a roof that’s 20+ years old, call (866) 650-8319 and we’ll give you a straight answer on what the roof actually needs, not what’s easiest to sell.
Why Gable Roof Repair Is Westwood’s Preferred Roof Replacement Company
Westwood homeowners keeping calling us for one reason: we don’t open with a replacement quote when a repair would hold. That matters here because a lot of the roofs in town are 1960s and 70s mill-era builds with low pitch and original decking, and a company that leads with tear-off isn’t doing you any favors. Neil Drummond built the company around inspection first, recommendation second, which is why our Roof Replacement estimates always start with what the decking, eaves, and underlayment are actually doing.
We’ve torn off enough double-layer asphalt on homes near Ash Street and along the Lassen National Forest boundary to know what wet pine needles under snowpack do to a roof over a single winter. That local pattern recognition means we quote Westwood jobs accurately, with the right ice and water shield specs and fire-resistant assembly, the first time. We’re not guessing from a satellite map.
For Westwood homeowners, response time matters when a spring melt exposes a leak. We schedule inspections in Westwood within a few business days during shoulder season, and our estimates are free regardless of whether you hire us. You’ll get a line-item quote with material brand options, decking scope, and no change-order games once work starts.
Styles & brands we work with






Roof Replacement Contractor in Westwood
A Roof Replacement Contractor in Westwood isn’t just swapping shingles; it’s rebuilding the weather barrier, usually on a roof that’s been fighting snow load for 40 to 60 years. In this town, the job starts with decking inspection because wet pine needles left under a snowpack rot valleys from the top down, and shingles don’t fix rotten wood. A full replacement in Westwood runs $9,500 – $16,200 for typical asphalt architectural shingles, and climbs higher when decking replacement or low-slope assemblies come into play.
Decking and Ice and Water Shield
On Westwood’s low-pitch roofs, we replace soft or delaminated OSB and plywood before anything else goes down. Then we run ice and water shield past the eave line, which matters at 5,000 feet where refreezing meltwater backs up under starter strips and into soffits. This is standard practice in snow country, and it’s non-negotiable here.
New Construction and Full Tear-Off
Newer builds in Westwood are limited, but when they do go up, snow-country detailing matters from day one: solid decking, proper nailing patterns for high-wind exposure, and underlayment rated for cold weather. For tear-offs, we work board-by-board so you see exactly what’s getting replaced and why. No mystery costs buried in the back half of the job.
Asphalt Shingle Roof Replacement in Westwood
Asphalt Shingle Roof Replacement in Westwood is the most common job we do here, and it’s a different animal than the valley jobs you’ll see quoted cheap. We’re installing architectural shingles rated for snow and wind, on decks that have been through real freeze-thaw cycles and pine needle seasons. Expect $9,500 – $16,200 for a typical single-story home with architectural shingles, and more if you’re coming off original wood shingles or a double-layer tear-off.
Architectural Shingles for Snow Country
Architectural shingles give you double-layer thickness at the key course points, which handles the weight and movement of heavy Sierra snowpack better than three-tab. They also carry higher wind ratings, which matters when winter storms come out of the north and put real uplift on the leading edges. For Westwood, we’d rarely recommend three-tab; the price difference doesn’t justify the performance drop.
Flat and Low-Pitch Roofing
Some Westwood homes have nearly flat sections over additions or porches, and shingles just don’t belong there. We spec membrane systems or modified bitumen with proper taper for drainage, then tie them into the shingle slopes with correct flashing details. Those transitions are exactly where leak calls come from, and they’re exactly where we slow down and do it right.
Trusted Brands We Service in Westwood
We work with seven shingle manufacturers, and for Westwood, the conversations usually come down to GAF, CertainTeed, and Tamko architectural lines. GAF is our most common spec here because of the snow-country warranty coverage and consistent supply, but CertainTeed and Tamko both carry solid architectural products that hold up at elevation. We stock fast-turnaround materials locally for Westwood jobs, which matters when a spring leak can’t wait on a supply house order. We work with your roof’s brand, not ours, so you get the right product for your exposure rather than whatever’s sitting on our yard.

AfterCommon Roof Replacement Problems We See in Westwood Homes
- Pine needle rot in valleys and gutters: Needles from the surrounding Lassen National Forest fill valleys every fall, and once they’re wet under snowpack, they hold moisture against the decking and rot it from the top down. If your valleys looked clogged before the first snow, count on decking repair when the roof comes off.
- Ice dam damage on low-pitch mill-era roofs: Homes built in the 1960s and 70s often have only felt underlayment at the eaves, which does nothing to stop refreezing water from backing up under the starter strip. We regularly find rotten soffit and wall cavities on the north-facing eaves of Westwood homes, not just damaged shingles.
- Re-nailed original shingles hiding soft decking: Some 55+ retirement homes in Westwood have had patch jobs layered over original wood shingles or worn three-tab, and the homeowner was never told the decking underneath is soft. Tear-off reveals it, and if a contractor doesn’t quote for it, they’re planning to either skip it or charge you later.
- Non-fire-rated assemblies in the wildland-urban interface: Westwood’s location inside the Lassen National Forest means your roof is part of your home’s fire defense. Original wood shingles or old three-tab with no Class A rating leaves your place exposed in a spot where evacuation routes are limited and response times matter.
Pricing for Roof Replacement in Westwood, CA
Here’s the honest math for Westwood’s market. Architectural shingle replacement on a typical 1,200 – 1,800 square-foot home runs $9,500 – $16,200, including tear-off, underlayment, drip edge, and standard flashing. If decking replacement comes into play, budget an additional $2.50 – $3.50 per square foot of affected deck area, which on a 55+ home with aging OSB can add $2,000 – $5,000 fast. Low-pitch areas needing membrane instead of shingles run higher per square foot because of the materials and detail work. You won’t get a number that means anything without someone looking at your roof; that inspection is free, and you’ll have a written line-item quote the same day. Call (866) 650-8319 to schedule it.

FAQs About Roof Replacement in Westwood
Because Westwood sits near 5,000 feet where snowpack refreezes at the eaves and pushes water back under shingles, ice and water shield is the only layer that stops that meltwater from rotting your decking and leaking into soffits. Valley roofs never see the freeze-thaw cycle that yours deals with for months each winter. Call (866) 650-8319 for an exact quote on your roof’s eave detail.
Yes, and most of the mill-era homes in Westwood keep their original framing; we replace the decking and upgrade the underlayment and eave detailing without touching structure. What does change is the assembly, including full ice and water shield and a properly rated shingle or low-slope membrane. Estimates are free, so call (866) 650-8319 and we’ll tell you what your specific roof needs.
Yes, because Westwood sits inside the Lassen National Forest and the wildland-urban interface is your daily reality, and a Class A assembly buys your home real time when fire moves through pine country. We spec Class A materials and details on every replacement here as a standard, not an upsell. Call (866) 650-8319 to schedule a roof inspection that will include this assessment.
Look at the decking allowance, the underlayment spec, the eave detail, and whether fire-resistant ratings are included; those four line items explain most of the price difference between a $10,000 and a $16,000 quote in Westwood. Both bids might say “architectural shingles” while only one includes ice and water shield and actual decking replacement. We’d be glad to walk you through your other bid line by line; call (866) 650-8319 and bring it to your free estimate.
We’re certified with seven manufacturers, and for Westwood we commonly install GAF, CertainTeed, and Tamko architectural shingle lines, each with different snow and wind coverage profiles. The right brand depends on your pitch, exposure, and whether you want a specific warranty term. Call (866) 650-8319 and we’ll spec the two or three options that actually fit your roof.
