We know the neighborhoods here because our crews are in them every week. From the tract layouts off Madera Road and Yosemite Avenue to the hillside parcels climbing toward Santa Susana Pass, we’ve torn off enough Simi Valley roofs to know what’s under them before the first square of shingles comes off. That local familiarity is why we can price a job accurately up front instead of discovering “surprises” at your expense later.

Why Tilehurst Roofing Is Simi Valley’s Preferred Roof Replacement Company

Tilehurst Roofing operates as a local member of the Kingswell family of roofing companies, founded in 2000. Greg Holloway runs our Simi Valley replacement work with a simple standard: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. That’s the Kingswell Way, and it’s not a slogan. It’s how every job is run.

Every crew that steps on a Simi Valley roof is background-checked and uniformed, so you know exactly who’s on your property. When you call, a live person answers. Not a voicemail tree, not a callback queue, not an answering service that will “try to reach the crew.” Day or night, seven days a week, including the weekends when most roofing problems get noticed.

Simi Valley homeowners have told us the same story many times. A contractor no-showed. Or the price changed at the door. Or a repair failed within months and nobody returned the call. Our entire process exists to be the opposite of that. You get a written price before any work starts. You get a written guarantee delivered before the crew leaves. And if a repair fails inside the coverage period, we return at no charge under our 365-Day Done Right Promise.

Asphalt Shingle Roof Replacement in Simi Valley

Asphalt Shingle Roof Replacement is the most common full replacement job in Simi Valley, simply because the city’s housing stock was built on it. From the late 1960s through the mid-1980s, tract builders covered low-pitched roofs with 3-tab composition shingles, and a significant number of those original or first-replacement roofs are now at the end of their service life. Inland valley heat accelerates the aging. Summer temperatures routinely exceed 100°F, and the thermal cycling splits shingles far faster than the same product would fail in coastal Moorpark or Thousand Oaks.

Tear-off and decking inspection

We strip the existing shingles down to the plywood and inspect every sheet before any new material goes down. On Simi Valley tract homes from the 70s, we regularly find decking that’s delaminated in the valleys from decades of thermal cycling, or water-stained sheets around skylights and penetrations that never showed from above. If decking replacement is needed, the price is quoted and approved in writing before we nail a single new square.

Class A material selection

Many Simi Valley reroofs, particularly in the hillside tracts around Wood Ranch and the Santa Susana Pass corridor, carry a Very High Fire Hazard Severity Zone designation. A permit in those zones legally requires Class A fire-rated roofing. We carry architectural shingle lines from GAF, Owens Corning, and Atlas that meet Class A standards, so the material is ready before the permit lands.

New Roof Installation in Simi Valley

New Roof Installation in Simi Valley comes up in two situations: new construction on the remaining infill lots in older neighborhoods, and complete tear-offs where the existing structure is too far gone to serve as a substrate. For new construction, the job includes full underlayment, drip edge, flashing, ventilation, and the finished roof system. For tear-offs, we handle the structural inspection as part of the scope, because the rafters and fascia under a 50-year-old Simi Valley roof often need attention before any roofing is applied.

Framing and ventilation

Opening up an older Simi Valley roof often reveals rafters that have swollen and split through decades of 100°F-plus summer heat and near-zero humidity during Santa Ana events. Undersized framing that was acceptable when the house was built may not hold nailing patterns to current wind rating standards. We address this up front. If a structural upgrade is required by code, it’s priced and approved in writing. No change orders sprung on you mid-project.

Underlayment and waterproofing

The waterproofing layer is where Simi Valley roofs quietly fail long before the shingles show wear. Cracked and shrunken ice and water shield along valleys and penetrations lets water intrude for years undetected. On every new installation, we replace the underlayment entirely. That’s not an upsell. It’s the difference between a roof that lasts 15 years and one that fails in 8.

Trusted Brands We Service in Simi Valley

We install and service roofing systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That’s seven major manufacturers, because the right product depends on your home’s pitch, fire-zone designation, and architectural style, not on what happens to be in the truck. For Simi Valley jobs, we stock the common architectural shingle lines and underlayment locally, so material lead times stay short. When a permit triggers a Class A upgrade, we already have the compliant materials accounted for in the estimate.

Common Roof Replacement Problems We See in Simi Valley Homes

• Failed waterproofing discovered mid-replacement. On tract homes from the 70s and 80s, the original ice and water shield along valleys and penetrations has shrunk, cracked, or vanished entirely. Water has often been intruding for years before the first shingle shows visible damage.
• Undersized or fire-treated framing that splits under thermal swings. Simi Valley’s extreme summer heat and near-zero Santa Ana humidity cause rafters to swell, crack, and lose their nailing integrity. Once the decking is exposed, a code-triggered structural upgrade is sometimes unavoidable.
• Aging wood shake on hillside homes near Santa Susana Pass. These roofs are both a fire liability and an automatic Class A compliance trigger on any permitted reroof. Homeowners expecting a like-for-like replacement often discover the permit legally requires a material upgrade.
• Delaminated decking in valleys and around penetrations. Four decades of thermal cycling separates plywood layers in the valleys of older Simi Valley homes, leaving soft spots that can’t hold new fasteners. We inspect every sheet and quote decking replacement before the roofing goes down.
