Why Mercer Roofing Is West Hills’s Preferred Roof Installation Company

West Hills homeowners call us because we do the paperwork other roofers fumble. Chapter 7A plan-check submittals for the LA City Building Department are routine for our crews, not a surprise mid-project. We detail enclosed eave assemblies, fire-rated underlayment spec sheets, and ember-resistant soffit venting on the first submission so your permit doesn’t stall.

Every technician who steps onto your property is background-checked, identity-verified, and photo-badged under the Threshold Verified standard. Before the visit, we send that technician’s name and photo to your phone. You know who’s coming. You see the badge at the door. No stranger walking up your driveway.

We also answer the phone. A live person, 24/7. Not a voicemail, not a callback form. When wind tears a ridge cap off at 6 a.m. during Santa Ana season, you talk to a human being. Grant Whitlock leads our team, and he holds every job to the 365-Day Done Right Promise: if the work isn’t right within a year, we make it right. Written on every job.

Tile Roof in West Hills

Tile roof installation in West Hills has become increasingly common as homeowners rebuild or reroof after the Woolsey Fire era, when insurance carriers and city plan checkers both started pushing for Class A fire-rated assemblies. Tile delivers that rating naturally, and it holds up against the Simi Pass wind corridor far better than aged composition shingles. We install tile over a fully replaced underlayment system, because the underlayment is what actually keeps water out. Most West Hills tile roof replacements run $28,000 – $55,000 depending on square footage, tile profile, and whether the existing decking is sound. Call (743) 200-8347 for a written line-item price.

Concrete and Clay Tile Replacement

On the 1960s and 1970s tract homes that dominate West Hills, we frequently see original concrete tile that’s reached the end of its structural life. Hairline cracks from decades of heat loading let water through to the underlayment below. We remove the old tile, inspect the decking, replace any rotted sheathing, then lay a new fire-rated underlayment before setting the new tile to manufacturer high-wind specifications.

Tile-to-Composition Conversions

Some West Hills homeowners switch from heavy tile to architectural composition shingles to reduce weight on older framing and cut cost. We handle that as a full tear-off, not an overlay. The Chapter 7A requirement applies either way, so we still install listed fire-rated underlayment and ember-resistant venting regardless of the top surface you choose.

Roof Ventilation in West Hills

Roof ventilation in West Hills is not an add-on; it’s a code requirement tied directly to the VHFHSZ designation. Chapter 7A mandates ember-resistant soffit venting with 1/8-inch mesh openings, which means the venting system has to be designed to keep embers out while still moving enough air to prevent attic heat buildup in the western Valley’s summer sun. We see failed plan checks all the time where the submittal lists standard off-the-shelf vents that don’t meet the mesh spec. Proper ventilation work on a West Hills re-roof typically adds $1,200 – $2,800 to the project, depending on linear footage and eave configuration. We’ll include it in your written estimate upfront so there are no surprises when the inspector walks the site.

Ember-Resistant Soffit Vent Retrofit

If your existing soffit vents have larger openings, they’ll fail inspection on a permit-triggered re-roof. We replace them with 1/8-inch mesh-rated ember-resistant vents and document the product spec for the plan check. This is one of the most common reasons we get called in to fix another contractor’s stalled permit in West Hills.

Attic Airflow Balancing for Valley Heat

West Hills summer heat loading is severe, sometimes 15 – 20 degrees hotter than coastal LA. We balance intake and exhaust airflow so your attic doesn’t bake your shingles from below. Thermal cracking in aged composition shingles accelerates dramatically when attic ventilation fails, which is why we treat ventilation as part of the roof system, not a separate upsell.

Trusted Brands We Service in West Hills

We install and repair shingle systems from GAF, CertainTeed, and Owens Corning, among others. For West Hills specifically, we stock high-wind starter strips and ridge cap materials that meet the manufacturer’s nail pattern requirements for the Simi Pass corridor. We also keep fire-rated underlayment and ember-resistant venting on hand because Chapter 7A demand in this area is constant. If you have a brand preference, tell us when you call, and we’ll price your roof with that system from the start.

Common Roof Installation Problems We See in West Hills Homes

• Wind-uplift at ridge caps and rakes: Simi Pass wind funnels through West Hills with enough force to pop ridge caps and lift field shingles at the rake edges, especially when the original roof was nailed to a standard pattern rather than the manufacturer’s high-wind spec. We see this most often on 1970s tract homes whose original roof was never upgraded.
• Chapter 7A plan-check rejection: Submittals that lack listed fire-rated underlayment spec sheets or ladder-style detailing for enclosed eave assemblies get bounced by the LA City Building Department. This stalls your permit and leaves your roof exposed. We handle these submittals correctly the first time.
• Overlay shortcuts on tight lots: Some contractors offer to overlay new shingles over old ones to save money. On a West Hills property in a VHFHSZ, that approach fails the requirement to bring the whole assembly up to current fire-zone code. It also adds weight to framing that’s already 40 – 60 years old.
• Decking rot hidden under old shake: The original wood shake roofs common to 1960s West Hills homes often concealed moisture damage underneath. By the time we tear off, we regularly find rotted decking sections that need replacement before any new system goes down.
