Westwood isn’t like other Lassen County towns. Nearly every house here traces back to the Flanigan Mill fire of 1911 and the fires that followed in 1912 and 1913, which means we’re rarely looking at new tract construction. We’re looking at 1910s through 1950s sawmill housing, built fast, built cheap, and now layered with decades of reroofs. That changes how we quote, how we strip, and how we rebuild.
Why Koreatown Roofing Is Westwood’s Preferred Roof Replacement Company
We’re roofing specialists, not generalists. Every job we take in Westwood is a roofing job, whether it starts as an inspection, a repair, or a full replacement. That focus matters when you’re opening up a roof on a house that’s seen a hundred winters on the Modoc Plateau. We don’t juggle a roofing crew one day and a kitchen remodel the next.
Homeowners off Ash Street, Birch Street, and throughout the old mill neighborhoods call us because we give them real material choices. We work with seven manufacturers – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – so your shingle recommendation is based on what fits your roof and your budget, not on what one supplier has sitting in a warehouse. Your roof, your material choice.
And because we’re a neighborhood-identity brand, not a franchised call center, our reputation walks around Westwood with us. When we quote a job on a mill-era house, we know the person we’re quoting will tell their neighbor whether we showed up when we said we would and whether the price held.

New Roof Installation in Westwood
New Roof Installation in Westwood is usually the call we get when someone has bought an older mill house and needs the roof redone before they can move in, or when a fire-damaged or badly rotted roof has to come off entirely. It’s not a reroof over existing shingles. It means stripping everything down to the framing, inspecting what’s there, replacing bad decking, and building the roof back up correctly. On a typical Westwood gable roof, a full new installation runs $14,000 to $22,000 depending on square footage and how much framing repair the old structure needs.
Full Tear-Off and Decking Replacement
The big variable on these old mill-era houses is the decking. Boards that were overdrawn and nailed by hand in the 1920s don’t always survive another tear-off. When we strip a roof in Westwood and find soft or split decking, we replace it before we lay a single shingle, and we write that allowance into your contract up front so the number doesn’t move on you mid-job.
Snow-Country Venting and Ice Shield
A new roof on the plateau has to handle deep wet snow and freeze-thaw cycles that would tear apart a roof built to valley standards. We run ice and water shield through valleys and behind chimneys, rework intake and exhaust venting, and set drip edge that holds up to real winter. That’s not an add-on on a new install. It’s the difference between a roof that lasts and one that leaks in its third season.
Reroofing in Westwood
Reroofing in Westwood means adding a new shingle layer over the existing roof, and it’s the right choice when the decking underneath is still solid and the roof has only one or two layers on it. On a standard Westwood mill house with a simple gable, a reroof typically runs $9,500 to $15,000. If we’re looking at three layered tear-offs, which is common on 1910s and 1920s housing, we’ll usually recommend a full tear-off instead because the extra weight is already stressing the framing.
Hand-Nailed Shingle Courses
What makes a Westwood reroof different from one in Redding or Chico is what’s under the old shingles. These houses were built by one lumber company, quickly, and the original roofs were hand-nailed. When we lift a course on a reroof, we often find the old nails have backed out and the shingles are riding on nothing. We re-nail or pull anything loose before the new layer goes down.
Ponderosa Needle Load
Surrounded by national forest, Westwood roofs collect ponderosa needles in the valleys and behind chimneys every fall. That load traps moisture against the shingles and underlayment, and over time it rots the roof from the top down. On a reroof, we clean every valley by hand, inspect what the needles have been hiding, and only then do we lay the new shingles.
Trusted Brands We Service in Westwood
We’re not locked into one manufacturer, and that’s why Westwood homeowners see us as a material-savvy option rather than a take-it-or-leave-it pitch. We install GAF, CertainTeed, Owens Corning, and IKO product lines regularly, plus three other leading brands, so you’re choosing from the names you already recognize at the lumberyard. Because we stock common flashing, underlayment, and ridge components for these lines, turnaround on a Westwood job stays tight even when a specific color or profile has to be ordered. We work with the brands you already trust.

AfterCommon Roof Replacement Problems We See in Westwood Homes
- Needle-packed valleys rotting decking from above. Ponderosa needles fill the valleys and hold snowmelt against the shingles all winter. By the time a homeowner sees the stain on the ceiling, the decking underneath is often soft enough to poke a finger through.
- Three-layer tear-offs hiding overdrawn decking. Mill-era houses got reroofed cheap and often. We’ve torn off three layers on a single Ash Street roof and found the original decking boards overdrawn, split, and barely holding nails. That’s why we never quote a reroof on a Westwood house without seeing what’s under it.
- Ice dams backing water under shingles behind chimneys. In a deep wet snow winter, the snow load just above the eave melts, refreezes, and pushes water back up under the shingle course. The fix is ice and water shield through the valleys and at the eave, plus better venting. On old roofs without it, the leak shows up every spring.
- Undersized original framing that a permit now flags. Once a permit is pulled and the roof is open, Lassen County code can require framing upgrades. A previous owner on one Westwood job had sistered in undersized pine rafters that would never pass inspection. We replaced them, priced and signed off before any new shingle went down.
Pricing for Roof Replacement in Westwood, CA
A standard reroof on a mill-era Westwood gable roof runs $9,500 to $15,000. A full tear-off with new decking lands between $14,000 and $22,000 on the same size house. The three things that move a Westwood quote: how many layers we’re stripping, whether the decking survives the tear-off, and what a permit triggers once the roof is open. We write material allowances into every contract so you’re not surprised if the framing needs work. Call (866) 974-2271 for a free estimate, and we’ll give you a written line-item price before any work starts.

FAQs About Roof Replacement in Westwood
Almost every Westwood roof covers a house built or rebuilt after the 1911 Flanigan Mill fire and the 1912-1913 fires, and those houses carry layered hand-nailed shingles over old decking that no one can fully inspect from above. Once we pull the old layers, the decking may be overdrawn or rotted in the valleys, and the framing may need code upgrades. We handle this by writing decking and framing allowances into the contract up front, so the quote moves within a set range and any additional work is priced and approved in writing before we touch it. Call (866) 974-2271 for an exact quote, and we’ll show you the allowance structure before you sign.
Ponderosa needles fill the valleys and the space behind chimneys every fall, trapping snowmelt against the shingles and underlayment. Then when deep wet snow cycles through freeze-thaw on the plateau, water backs up under the shingle courses and finds its way inside. The fix is a full valley clean-out, ice and water shield through the valleys and behind the chimney, and venting that keeps the roof deck cold enough to prevent the melt-refreeze cycle. The work is standard on every Westwood replacement we do. Call (866) 974-2271 to have us look at your roof’s specific failure points.
Yes, Lassen County requires a permit for a roof replacement, and once the roof is open, code upgrades to venting, flashing, and soffit/fascia can come into play. That’s the single biggest reason a Westwood quote moves mid-job. We pull the permit, we know the local inspector and the typical callouts, and we price the likely upgrades into the estimate before we start. This is one of the ways a roofing-only contractor differs from a generalist. Call (866) 974-2271 and we’ll explain what your specific house will trigger.
A square in roofing is 100 square feet of roof surface. We measure every plane of your roof in person and write the square count directly on the estimate, so you can see the math behind the price. On old Westwood mill houses with dormers, steep gables, or additions, the square count can be higher than the footprint of the house, and we show that in the line items. Call (866) 974-2271 for a free measure and a written quote with the squares listed.
We replace damaged decking with code-rated plywood or OSB to match the existing thickness, and on the shingle side Westwood homeowners typically choose GAF architectural shingles for the snow load and UV exposure, though we also install CertainTeed, Owens Corning, and IKO. The key on a mill-era house isn’t the shingle brand, it’s what’s underneath: ice and water shield through the valleys, new drip edge, and a deck surface that can actually hold a nail. We’ll show you samples and let you pick, because your roof, your material choice. Call (866) 974-2271 to schedule a free estimate.
