Roofers in West Hills, CA
West Hills roofing work is different from the rest of the San Fernando Valley, and it comes down to three things: steep hillside roof planes, heavy tree cover, and Santa Ana winds that push embers and debris into places flatter neighborhoods never worry about. Homes here were mostly built between the 1960s and 1990s, which means a large share of the original roofs are reaching the end of their service life right now. If you’re looking for roofers in West Hills, CA who understand those conditions, call Mercer Roofing at (805) 309-3314 for a written estimate before any work begins.
Why West Hills Homes Are Different
West Hills sits against the western edge of the Valley, and the terrain shapes everything about how roofs here age and fail. Streets climb into the hills, and many homes have multiple roof planes meeting at odd angles. That geometry creates more valleys, more flashing points, and more places where water finds a way in when a detail is done carelessly. Upper neighborhoods near Castle Peak Park are a good example: a lot of those homes have red clay tile roofs, and where several planes intersect, the flashing work is the difference between a roof that lasts decades and one that leaks in the first winter rain.
Then there are the trees. West Hills has more mature oaks and eucalyptus than most of the surrounding area, and those trees drop leaves, bark, and seed pods year-round. Debris piles up in valleys and behind chimneys, holds moisture against shingles, and fills gutters faster than homeowners expect. We regularly find rotting fascia boards on West Hills homes where irrigation overspray from landscaping keeps wood damp for months at a time. Add in hot, dry summers that bake asphalt shingles and Santa Ana winds that drive debris under flashing, and you have a roofing environment that rewards experience and punishes shortcuts.
Styles & brands we work with
Our Main West Hills Services
Most West Hills homeowners call us for one of two reasons: a roof that is leaking or showing storm damage, or a roof that has simply aged out and needs full replacement. Both jobs run through the three service pages below.
Roof Repair in West Hills
Repair work here tends to cluster around a few repeat offenders: lifted flashing where tile and shingle planes meet, cracked tile from wind-driven branches, and leaks around chimneys and skylights that were flashed with materials now past their useful life. In the hillside neighborhoods, we also see a lot of wind-related damage after Santa Ana events, when gusts channel through the canyons and tear loose sections that were never properly nailed. Every repair we quote includes a written price before work starts and a written guarantee. For details on what repair looks like on a West Hills roof, see Roof Repair in West Hills.
Roofing Company in West Hills
When homeowners search for a roofing company in West Hills, they’re usually trying to answer one question: who can I trust to show up and do this right without surprises? We’re part of the Threshold Group family, founded in 2000, and every technician who arrives at a West Hills home is background-checked, identity-verified, and wearing a photo ID badge. You’ll know the technician’s name and face before they knock. Read more about how we operate on Roofing Company in West Hills.
Roof Installation in West Hills
Most full replacements in West Hills involve tearing off an original wood shake or asphalt shingle roof from the 1970s or 1980s and deciding what goes back on. Tile is common in the upper hills, while dimensional asphalt shingles dominate the flatter streets. The condition of the decking underneath matters a lot on older homes, and we include decking replacement in the written quote when inspection shows it’s needed, so there’s no mid-project surprise. We install GAF, CertainTeed, and Owens Corning shingle systems, among others. Full details at Roof Installation in West Hills.

AfterPricing for Roofers in West Hills, CA
Roofing prices in West Hills run slightly above Valley averages because of hillside access, tree work, and the amount of flashing detail on multi-plane roofs. Here are the ranges we typically quote:
| Service | Typical range in West Hills |
|---|---|
| Minor roof repair (shingle or flashing) | $350 – $750 |
| Major repair (valley, chimney, or decking work) | $1,200 – $3,000 |
| Full asphalt shingle replacement | $12,000 – $22,000 |
| Full tile roof replacement | $25,000 – $45,000 |
| Decking replacement (per sheet) | $95 – $140 |
| Gutter replacement (per linear foot) | $9 – $16 |
| Skylight flashing repair | $500 – $1,100 |
| Fascia board replacement (per board) | $250 – $600 |
What pushes a West Hills roof toward the top of those ranges is access: steep driveways, limited space for staging, and the extra time required to protect landscaping close to the house. Whatever the number, you get it in writing before any work starts, and it does not change unless you approve a change in writing first.
