Fast, Reliable Roof Replacement Across West Hills
Roof replacement in West Hills typically runs $12,000 – $28,000 for a standard asphalt shingle job on a 2,000-square-foot home, with most projects completed in 2 – 4 days once materials arrive. We serve homeowners from the valley floor near Fallbrook Avenue up through the knolls above Roscoe Boulevard, where the Santa Susana winds hit harder and roofs age faster than they do just a few miles south in the basin.
We’re Crestview Roofing, part of the Relay Home Co. family since 2000, and our crews work West Hills regularly enough that we know which permits Los Angeles County wants for homes above the ridgeline versus those below it. Dylan Pace built this company on The Relay Visibility Guarantee: a written price before any work starts, live trackable arrival times, before-and-after photo documentation, and a digital invoice sent by text. No four-hour windows. No price balloons at the door. Call (325) 246-5075 to schedule your free estimate.
Why Crestview Roofing Is West Hills’s Preferred Roof Replacement Company
West Hills sits at the western edge of the San Fernando Valley, and that geography creates roofing problems you don’t see in Burbank or Studio City. The afternoon Santa Ana winds tear at shingle tabs on south-facing slopes. The thermal cycling between 105-degree August days and 45-degree January nights fatigues flashing faster than in coastal zones. We’ve replaced enough roofs on Lurline Avenue and between Platt Avenue and Shoup Avenue to recognize the pattern: homes built in the 1960s and 70s with original wood shake underlayment that finally gives out, or the 1980s tract homes with three-tab shingles that hit year 22 right on schedule.
Our Roof Replacement team coordinates dispatch from our Los Angeles office, but the crews serving West Hills are local. That matters when you need a question answered at 6 p.m. on a Thursday or when a surprise rain cell rolls in from the Santa Susanas and you need the tarp crew fast. A live person answers our phones 24/7. No voicemail loops. No “call back Monday.”
Every job carries our 365-Day Done Right Promise in writing. If a covered repair fails within a full year, we correct it at no charge, including a free second visit. The price we write down before work starts is the price on your invoice. Period.
Reroofing in West Hills
Reroofing in West Hills means stripping the existing roof system to the deck, inspecting for hidden water damage, and installing a complete new assembly that meets current Los Angeles County wind-uplift requirements. Most West Hills homeowners need this when their roof hits 20 – 25 years, when they spot granule loss in the gutters, or when a home sale inspection flags the existing roof. A typical reroofing job here runs $12,000 – $22,000 for asphalt shingles on a standard single-story home, with architectural shingles adding $2,000 – $4,000 for the upgraded wind rating and dimensional look.
Deck Inspection and Replacement
We pull every shingle and felt layer to expose the roof deck. In West Hills, we regularly find plywood delamination near vent stacks and chimney saddles where decades of thermal movement cracked the seal. If the deck is compromised, we replace those sections with 5/8-inch CDX plywood before the new underlayment goes down. This isn’t an upsell; it’s structural. We photograph everything and show you before we proceed.
Underlayment and Ventilation Upgrades
Modern code requires synthetic underlayment and ice-and-water shield in valleys. Many West Hills homes from the 70s and 80s lack adequate ridge venting, which traps summer heat and accelerates shingle aging. We calculate net free vent area and add ridge vents or box vents where needed so your new roof actually lasts its full rated life.
Flat Roof Replacement in West Hills
Flat Roof Replacement in West Hills covers the low-slope sections common on ranch additions, patio covers, and the modernist homes tucked into the hills above Victory Boulevard. These roofs demand different materials than pitched roofs, typically TPO single-ply membrane, modified bitumen, or built-up roofing with a reflective cap sheet. A flat roof replacement here generally costs $8,000 – $18,000 depending on square footage, existing insulation condition, and whether we need to re-slope for drainage. West Hills sees enough winter rain that ponding water destroys a flat roof in five years if the drainage isn’t right.
TPO and Reflective Membrane Systems
We install white TPO membranes that reflect solar heat, which matters enormously in West Hills where flat roofs on south-facing additions can hit 160 degrees in August. TPO seams are heat-welded, not glued, so they hold against the Santa Ana gusts that peel lesser materials. Manufacturer warranties run 15 – 20 years when installed to spec.
Drainage Corrections
Flat isn’t actually flat; it needs 1/4 inch per foot minimum slope to drains or scuppers. We find original West Hills flat roofs that settled or were framed wrong, creating low spots. We rebuild the slope with tapered insulation board before membrane installation so water moves off the roof instead of sitting and breeding leaks.
Trusted Brands We Service in West Hills
We install GAF Timberline HDZ and CertainTeed Landmark architectural shingles on most West Hills homes, with Atlas StormMaster Slate and Tamko Heritage Vintage available for homeowners who want a heavier dimensional profile or enhanced wind warranty. For tile and specialty applications, Boral clay and concrete products handle the Santa Susana exposure without the fading you see in lower-grade materials. We don’t special-order from a warehouse three counties away; we maintain stocked relationships with distributors in the San Fernando Valley so your material lead time stays short and your project stays on schedule. Every brand we carry backs its products with transferable manufacturer warranties, and we register those warranties on your behalf so there’s no paperwork gap.
Common Roof Replacement Problems We See in West Hills Homes
- Santa Ana wind damage on south and west slopes. The gusts that funnel through the Santa Susana Pass lift shingle tabs and drive debris into the roof surface. We see this concentrated on homes above Roscoe Boulevard and along the exposed ridgelines, where standard three-tab shingles often fail before year 15.
- Thermal cycling fatigue in original 1960s – 1980s housing stock. Daily temperature swings of 40+ degrees in summer expand and contract flashing, vent boots, and valley metal until they crack. These homes cluster between Fallbrook Avenue and Platt Avenue, and the damage usually hides until a heavy rain exposes it.
- Inadequate attic ventilation baking shingles from below. Many West Hills builders prioritized cost over airflow. Without sufficient intake and exhaust vents, attic temperatures hit 140 degrees and cook the asphalt from the underside, cutting shingle life by a third.
- Flat roof ponding on additions and patio covers. The gentle winter rains aren’t dramatic, but they persist. Water that sits for more than 48 hours degrades any flat membrane, and we replace far too many patio roofs that failed because the original slope was never correct.
Pricing for Roof Replacement in West Hills, CA
Most full roof replacements in West Hills fall between $12,000 and $28,000, with the majority of asphalt shingle jobs landing in the $14,000 – $20,000 range for a typical 2,000-square-foot home. Architectural shingles add 15 – 25 percent for the thicker profile and longer warranty. Flat roof replacement runs $8,000 – $18,000. Roof decking replacement, when needed, adds $3 – $5 per square foot. These numbers reflect West Hills’s specific market: material costs track Los Angeles County, but access challenges on hillside lots above Victory Boulevard or between Shoup Avenue and the county line can add labor time.
What moves the number: roof pitch (steeper = more labor), deck condition, number of penetrations (skylights, vents, chimneys), and whether we’re removing one layer or multiple previous roofs. We give you a written line-item quote before any work starts. The price on that quote is the price on your invoice. No change orders unless you add scope. Call (325) 246-5075 for your free estimate.
