Fast, Reliable Roof Replacement Across Westwood
A full roof replacement in Westwood generally runs between $11,000 and $24,000 for a typical single-story home, with architectural shingles landing around $13,500 – $19,000. Most jobs take three to five working days once tear-off begins. We work throughout the 96137 ZIP, and we know what these mill-era houses throw at a crew when the old layers come off. If you’re looking at sagging eaves, ceiling stains, or shingle granules in your gutters, call (866) 321-6172 for a free estimate from Van Nuys Roofing Co.
Westwood is not a valley town. At right around 5,000 feet on the eastern edge of the Sierra Nevada, the roofs here take snow load, ice, and high-elevation UV in a way that flatland roofs never do. That changes how we spec underlayment, venting, and nailing patterns. It also means when we tear off a roof on a 1950s mill house, we’re usually the first people to see the decking since Eisenhower was in office. We plan for that.

Why Van Nuys Roofing Co Is Westwood’s Preferred Roof Replacement Company
We’re not a one-brand shop. That matters more in Westwood than most people realize, because the right roofing material for a house off Ash Street is not automatically the right material for a house backing up to open timber on the town’s edge. Our Roof Replacement team installs GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Seven leading brands, one crew that knows them all. We inspect first, recommend second. If a repair buys you five more years, we’ll say so. If replacement is the only honest move, we’ll show you why with photos from your own roof.
Rick Dominguez runs our crews, and the standard he sets is simple: no upselling, no fear-selling, and no material recommendation driven by supplier incentives. Your roof, your material choice. We’ll walk you through the spec differences between architectural lines, fire ratings, and warranty eligibility for each brand, then let you decide. Westwood homeowners routinely tell us that conversation alone is why they called us back for a second project.
We’re based in Van Nuys but our crews work the whole region, and we schedule Westwood jobs in focused blocks so we’re not burning a day driving back and forth across the mountains. That keeps your project moving and keeps waste buildup off your property. When snow season is coming, we push extra crews to finish Westwood tear-offs before the first hard freeze.
Styles & brands we work with
Flat Roof Replacement in Westwood
Flat roof replacement in Westwood almost always means a low-slope porch roof, carport, or a small addition on one of the mid-century mill houses that make up most of the 96137 housing stock. These aren’t big commercial flats. They’re 300 to 600 square feet, framed with lumber that’s often been carrying multiple shingle layers for decades, and they fail quietly until water shows up on the ceiling below.
What We Find and How We Fix It
The most common flat roof failure we see in Westwood is ponding at the low edge where the porch roof ties into the main wall. Snow melt sits there, freeze-thaw works the membrane loose, and by the time you see a stain, the decking is already soft. We tear off to bare framing, replace rotted decking, check the rafter tails, and install either a torch-down modified bitumen system or a peel-and-stick membrane depending on slope and exposure.
A flat roof replacement on a Westwood porch typically runs $2,800 – $6,500, depending on size, decking replacement, and whether we’re adding taper insulation to fix the ponding problem rather than just covering it. If the slope is too shallow to drain, no membrane in the world will keep it dry. We fix the slope first. That’s the difference between replacing a roof and replacing a problem.
Roof Installation in Westwood
Roof installation in Westwood breaks into two camps: replacing the roof on an existing mill-era home, or roofing new construction. The existing-home work is what most people call us for. The new construction work is growing, especially on lots cleared after the Buffalo Chips Fire changed the town’s edges in the 1990s.
Replacement on Existing Homes
Replacement means full tear-off, decking inspection, and a new system built for Westwood’s actual conditions: ice and water shield in the valleys and along the eaves, proper attic ventilation, and a nailing pattern rated for high-wind and heavy-snow exposure. Architectural shingles are the standard choice for most Westwood homes, and we install GAF, CertainTeed, and Owens Corning architectural lines most often. Boral tile comes up on higher-end rebuilds where the homeowner wants a stone-coated or concrete profile that holds up to UV better than asphalt over 30-plus years.
New Construction Roofing
For new builds, we work from engineered plans or help you spec the roof system before framing starts. That’s the cheaper way to do it: getting curb and venting details right before the rafters are set. New construction roofing in Westwood typically runs $14,000 – $28,000 depending on footprint, pitch, and material class.
Trusted Brands We Service in Westwood
We stock common accessories for GAF, CertainTeed, and Owens Corning systems locally, so when a Westwood job needs a specific ridge cap or a CertainTeed color match mid-install, we’re not waiting on a shipment from Sacramento. That speed matters in a mountain town where the weather window closes fast. Boral and the other lines we install come with manufacturer warranty eligibility that a single-brand shop simply cannot offer. No brand steering, no “this is what we have on the truck” default. We install what fits your budget and your site conditions.
Rick Dominguez puts it this way: if a crew only knows one brand, every roof gets that brand, whether it’s the right call or not. We’d rather know seven and let the roof tell us what it needs.
Common Roof Replacement Problems We See in Westwood Homes
- Ice damming at the eaves. Westwood’s freeze-thaw cycles push meltwater under the shingles at the roof edge, and blocked soffit vents make it worse. We see this on nearly every original 1940s – 1970s house we open up, and the fix is a combination of better ventilation and ice and water shield, not just more shingles.
- Untreated wood shake on older homes. Many mill-era houses still carry the original shake, which does not meet Class A fire-rated assembly requirements. After the Buffalo Chips Fire, that’s not a paperwork issue in Westwood. It’s a real liability, and we flag it on nearly every inspection of an older home near the town’s edge.
- Multiple shingle layers hiding bad decking. We regularly tear off two or three shingle courses on Westwood homes. The layers hide soft sheathing and split rafters until tear-off exposes them. That’s why our contracts include written allowances for framing and decking repairs, priced and approved before we touch anything.
- Undersized porch framing. The low-slope porch roofs on mill homes were often framed with 2×4 rafters never engineered for Sierra snow load. Opening them up during a replacement frequently means sistering rafters before new decking goes down.

FAQs About Roof Replacement in Westwood
We price it before we touch it, not after. Every replacement contract we write includes a written allowance for decking and framing repairs, and when we find rot or broken rafters under the old shingles, we photograph it, show you exactly what we found, and get your written approval on any work beyond the original allowance. On a 1950s mill house off Ash Street, we tore off three layers of shingles and found the original 1×6 sheathing had dry rot around the chimney flashing and valleys. Our crew sistered two cracked rafters, replaced the rotten decking, and installed full ice and water shield before laying GAF Timberline architectural shingles with a ridge vent. The homeowner approved the extra framing work in writing before we did it. That’s the way every Westwood job runs. Call (866) 321-6172 and we’ll give you a straight answer on what your roof likely needs.
Yes. We use a high-nailing pattern and longer nails on Westwood roofs than we would on a valley house in Sacramento or the Bay Area, because the sustained snow load and wind exposure at 5,000 feet demand more fasteners per shingle and a different underlayment spec. Ice and water shield along the eaves and in the valleys is standard on every Westwood replacement we do, not an upgrade. The original 1940s – 1970s mill houses were not built with these provisions, so part of the job is bringing the roof up to current mountain-region installation standards, not just slapping new shingles over old framing.
You can, but we’d recommend against it, and here’s the straight reason: untreated wood shake does not meet Class A fire-rated assembly requirements, and in a town where the Buffalo Chips Fire burned through the surrounding timber in the 1990s, that’s a genuine risk rather than an insurance formality. Some homeowners keep shake for the aesthetic, but the maintenance and re-treatment cost over a decade usually exceeds a full architectural shingle replacement. We’ll show you the condition of your shake in photos during the inspection and let you decide. The estimate is free either way.
Because shingles, underlayment, and decking are all manufactured and sold in squares, which is roofing shorthand for 100 square feet. A 1,600-square-foot home in Westwood typically has an 18 – 22 square roof once you account for pitch and overhangs. Measuring in squares lets us quote exact material quantities instead of guessing, and it’s the same unit your warranty paperwork and any supplemental insurance claim will use. If a contractor quotes you a price without squares, you’re getting a guess, not a quote.
We pull permits on every full roof replacement in Lassen County, and we schedule the inspection with the county rather than asking you to deal with the building department. When the roof is open and we find undersized framing or blocked venting that will fail code, we document it, price the fix, and get written approval before proceeding. The most common code upgrade on Westwood mill homes is sistering the low-slope porch rafters, which were often framed with 2x4s that don’t meet current snow-load requirements. The permit process adds a day or two to the job, but it protects you on resale and keeps the warranty valid. Call (866) 321-6172 and we’ll tell you exactly what your house will likely trigger.
