Fast, Reliable Roof Replacement Across Westwood
Roof replacement in Westwood runs $11,000 to $19,000 for a typical single-story asphalt shingle roof on the acreage lots that define this part of Lassen County. For flat roofs on shops, carports, or outbuildings, expect $8 to $14 per square foot installed. The two things that move the quote most in Westwood are snow load and county permitting, which we’ll get into below. If you’re looking at a ceiling stain that showed up after the last melt, call us at (833) 589-7850. We’ll tell you what the roof actually needs, whether that’s a repair, a full replacement, or nothing yet.
Bedrock Roof Repair works throughout the Westwood area, from the homes near the old mill site and the commercial core around Third Street out to the acreage parcels toward the Eagle Lake basin. Alan Cofield runs our team with a repair-first approach. We inspect, then we tell you the truth. Same team from inspection to final nail.
Why Bedrock Roof Repair Is Westwood’s Preferred Roof Replacement Company
We’ve torn off enough Westwood roofs to know the failure pattern before we set a ladder. Curled south-facing shingles, ice-dam stains at the eaves, valleys that leaked during April melt, not during the storm that filled them. That local pattern recognition means our quotes account for what actually happens at 5,100 feet, not what happens on a spec sheet.
Westwood homeowners call us because we carry access to GAF, CertainTeed, Owens Corning, IKO, and three other leading manufacturers. That means the shingle we recommend is the one that fits your roof’s exposure and your budget, not the one we’re pushed to sell. Alan Cofield has built the company around that honesty. If a roof needs repair instead of replacement, we say so. The name “Bedrock Roof Repair” is a public commitment to that sequence.
We’re licensed and insured, and our Westwood customers can verify that before we touch the roof. The estimate is free, and it’s a written line-item quote. No change orders on the back end.
Styles & brands we work with






Reroofing in Westwood
Reroofing in Westwood means tearing off the existing layer or layers down to the decking and setting a new roofing system, and on most of the older mid-century cabins and ranches here, that tear-off is a two-layer job. Homes built around the mill era often had a second layer of asphalt shingles laid over the first at some point in the last forty years. Those bottom layers are dried out and brittle now, baked by the same high-altitude sun that curls the top course. A reroof fixes the actual decking and lets us run ice and water shield where the snowmelt leaks showed up at the eaves and in the valleys.
A full reroof on a typical Westwood single-story home runs $11,000 to $19,000, depending on square count, decking repair, and whether we’re addressing ventilation. The tear-off and deck inspection is the part you don’t skip at this elevation. Hidden deck rot under old valleys is common, and fixing it before the new shingles go down is the difference between a roof that lasts and one that leaks again in three melt seasons.
Snow-Melt Deck Repair
When snow sits on a Westwood roof and melts slowly, water finds every seam and nail hole that was marginal anyway. On a reroof, we pull the shingles and check the deck at every eave and valley before anything gets re-covered. Replacing soft or delaminated decking adds $65 to $90 per sheet, and it’s quoted in the line item, not discovered later as a surprise.
UV-Stable Shingle Selection
South-facing slopes in Westwood age out years before north-facing ones. We quote the whole roof off the sunniest slope’s wear, then choose an architectural shingle with the granule and UV stability to handle the exposure. GAF, CertainTeed, and Owens Corning all make lines that hold up to this kind of sun, and we’ll show you the difference in cost and expected life before you choose.
Flat Roof Replacement in Westwood
Flat roof replacement in Westwood usually means a shop, carport, or detached outbuilding on an acreage parcel, and it’s a different animal from a sloped house roof. These roofs run $8 to $14 per square foot installed, and the material choice matters more here than anywhere else because ponding water and UV damage do the work of destruction. On a flat roof, the membrane is the waterproofing, the UV barrier, and the walking surface all at once.
Most flat roofs we replace in Westwood are on outbuildings or shops set close to a well head or septic field. That changes how we stage. Tear-off debris can’t get dumped anywhere convenient if it threatens a septic line. We plan material hauls and debris staging around the setbacks before we ever quote a square.
Single-Ply Membrane Systems
TPO and EPDM are the two main membrane routes for Westwood flat roofs. TPO holds up better under the high-altitude UV, and it’s the one we recommend more often out here. A properly installed TPO roof on a Westwood shop should shed snowmelt and stand up to the afternoon sun for well over two decades.
Shop and Outbuilding Scoping
Flat roofs on outbuildings often hide problems at the parapet walls and around vents. We inspect the flashings, the drain locations, and the deck condition before quoting. If the roof is close to a septic tank or well line, we flag that on the quote and plan the job so no equipment crosses those setbacks.
Trusted Brands We Service in Westwood
Bedrock Roof Repair sources from seven roofing manufacturers including GAF, CertainTeed, Owens Corning, and IKO. What that means in Westwood is a real material choice. If your roof takes heavy snow and long sun, you might lean toward a CertainTeed or GAF architectural line built for high wind and UV. If budget is the driver, we’ll show you what an Owens Corning or IKO option costs and what you trade for those savings. We order what the job needs. No warehouse pushing one brand. Same team from inspection to final nail.

AfterCommon Roof Replacement Problems We See in Westwood Homes
- Spring-melt eave and valley leaks. The snowpack fills over winter, then melts in April and the water runs down to the eaves where the ice dam forms. If ice and water shield wasn’t run far enough up, the leak shows up weeks after the storm, and it shows up on the ceiling, not the roof.
- South-facing slope wear. Afternoon sun at 5,100 feet bakes the south-facing shingles years faster than the north-facing ones. We’ve seen south slopes that were granule-bare and curling while the north slope still had five years left. Whole-roof quotes get built off the worst slope.
- Two-layer tear-offs on mid-century homes. Many older Westwood houses have two layers of asphalt shingles layered over the original deck. Both layers are usually shot, and the deck under the valleys is often soft from decades of slow melt seepage.
- Outbuilding and shop roofs near well and septic setbacks. On acreage parcels, the shop roof often sits close to a well head or septic field. That changes tear-off debris staging, material placement, and equipment routes. We scope those constrictions on the quote so the price you see is the price it costs.
Pricing for Roof Replacement in Westwood, CA
Here’s what Westwood homeowners should expect on a roof replacement quote. A standard single-story asphalt shingle roof on a 1,200 to 1,800 square foot home runs $11,000 to $19,000. Flat roofs on shops and outbuildings land at $8 to $14 per square foot. Decking repair adds $65 to $90 per sheet.

FAQs About Roof Replacement in Westwood
Most Westwood roof replacements on acreage parcels are permitted through Lassen County, not the city of Westwood, and the county will ask about setbacks to wells, septic fields, and property lines as part of the permit. We handle that county permitting for you. Roof Replacement on a county-permitted parcel means the scope includes more than shingles, so we check setback distances and flag any outbuilding questions before we quote. Call (833) 589-7850 and we’ll tell you what your parcel needs.
The leak was always there, but the water was frozen. Snow sits on your roof all winter, then the spring melt releases it, and it runs down to the eaves and valleys where ice dams form. If ice and water shield was skipped or under-run on the original install, that melt water finds the seam and shows up on your ceiling in April. We see it every melt season across Westwood. Call (833) 589-7850 and we’ll trace where the melt is getting in.
We start with the roof itself, then we walk the parcel. On an open Westwood lot, the price changes based on where we can stage materials, where tear-off debris can go, and whether the shop or outbuilding sits near a well head or septic field. Grading and drainage around the structure matter too. We measure those constrictions before we quote, so the price reflects the actual job, not a square foot multiplied from a satellite image. Call (833) 589-7850 for a free site walk.
No. South-facing slopes in Westwood wear out years faster than north-facing ones because of the intense afternoon sun at 5,100 feet. That’s why we quote the whole roof off the sunniest slope’s condition, and it’s why we recommend UV-stable architectural shingles from brands like CertainTeed or GAF for the high-desert sun. The line item tells you what you’re paying for on each slope.
Yes, flat roof replacement on shops, carports, and outbuildings is a regular part of our work in Westwood. These roofs run $8 to $14 per square foot, and the membrane choice depends on UV exposure and whether the building sits near a septic field or well. We scope the staging before we quote, so the tear-off and material haul never cross a setback. Call (833) 589-7850 to schedule a free estimate on your outbuilding roof.
