Roofing Contractor in Simi Valley, CA

Simi Valley Roofing — Local Expertise, Quality Results

Simi Valley's suburban tract homes are carrying aging 3-tab shingle roofs well past their service life — and hillside areas near Tierra Rejada carry fire hazard designations that make Class A upgrades a practical necessity. Caspi Construction handles both under City of Simi Valley permits.

The Wood Ranch, Big Sky, and Bridle Path neighborhoods of Simi Valley were developed across the 1970s through the 1990s with composition shingle roofs — three-tab products that carried 20-year ratings and have now been in service for 25 to 45 years in many cases. Granule loss, curling shingles, and brittle tabs that crack in wind events are the telltale signs that Simi Valley homeowners are recognizing. The hillside areas near Rocketdyne and Tierra Rejada carry fire hazard designations that make Class A roofing the right specification on any re-roof regardless of condition — the fire risk justifies the upgrade even when the existing roof is not yet failing. A roofing contractor in Simi Valley who understands both the suburban tract home context and the hillside fire zone requirements — and who navigates the City of Simi Valley's permit process rather than LADBS — is what Simi Valley homeowners need. Caspi Construction is a licensed Simi Valley roofing company (CSLB #1091631) with a 4.9★ rating.

Our Simi Valley Roofing Services

Three-Tab to Architectural Shingle Upgrade

Replacing aging three-tab shingles with modern Class A architectural shingles is the most common Simi Valley roofing project. Architectural shingles offer meaningfully better performance — thicker profiles, enhanced wind uplift resistance, and a 30-year warranty — compared to the three-tab products they replace. We install CertainTeed, GAF, and Owens Corning Class A architectural shingles in the profile and color appropriate to each Simi Valley home, and perform a complete tear-off and deck inspection before any new material goes down.

Class A Fire-Rated Roofing for Hillside Areas

Simi Valley hillside properties near Rocketdyne and the Tierra Rejada corridor carry fire hazard designations that make Class A roofing materials appropriate on any re-roof. We identify your property's fire risk classification during the inspection and specify Class A products and underlayment systems that meet the applicable requirement. Ember-resistant ridge venting is a standard upgrade recommendation for all Simi Valley hillside roofing projects.

Ridge Ventilation System Upgrade

Older Simi Valley tract homes typically have turtle vents or gable vents as their primary attic ventilation — systems that provide inadequate ventilation volume for the roof areas they serve. Replacing discrete turtle vents with continuous ridge venting improves attic temperature management, reduces shingle degradation from beneath, and improves the home's overall energy performance. We install continuous ridge vent as a standard upgrade on all Simi Valley roof replacements.

City of Simi Valley Permit Management

All re-roofing work in Simi Valley requires permits through the City of Simi Valley Building & Safety Division — not LADBS. Caspi Construction manages all City of Simi Valley permit applications, schedules required inspections, and coordinates final sign-off as a standard part of every roofing project.

Recent Roofing Projects Near Simi Valley

Project 1 — Wood Ranch Three-Tab to Architectural Upgrade

A Wood Ranch homeowner had a 28-year-old three-tab shingle roof that was visually worn and had developed two soft spots at valley locations. The homeowner wanted an upgrade to a dimensional architectural product. We tore off the existing three-tab shingles, replaced 130 square feet of deteriorated OSB decking at the two soft spots, installed GAF WeatherWatch self-adhering underlayment at all eaves and valleys, and applied GAF Timberline HDZ architectural shingles in Weathered Wood. A continuous ridge vent replaced the four turtle vents, and new drip edge was installed at all eaves and rake edges. City of Simi Valley permit was managed. The roofing renovation in Simi Valley was completed in two days.

Project 2 — Bridle Path Hillside Fire-Resistant Re-Roof

A Bridle Path homeowner on a hillside lot in a Simi Valley fire hazard area had a 22-year-old architectural shingle roof that was approaching end of life. The fire hazard designation made a Class A upgrade the appropriate choice regardless of whether the existing roof had more years left in it. We replaced the entire roof system with CertainTeed Landmark TL architectural shingles in Weathered Wood (Class A rated), replaced all flashing with new aluminum, installed ember-resistant ridge and soffit venting throughout, and managed the City of Simi Valley permit including the fire hazard area documentation addendum. Completed in two days.

Project 3 — Big Sky Ranch Home Full Tear-Off

A Big Sky homeowner had a 34-year-old roof — the original shingles from construction — with granule loss throughout, curling tabs on the south slope, and a chimney flashing that had pulled away from the chimney mortar in two locations. We completed a full tear-off, replaced 90 square feet of compromised decking adjacent to the chimney, installed new aluminum step and counter flashing at the chimney with new caulking, applied self-adhering underlayment at eaves and valleys, and installed Owens Corning Duration Storm architectural shingles in Teak — a Class A product with enhanced wind uplift resistance appropriate to Simi Valley's occasional Santa Ana wind exposure. Continuous ridge vent replaced the original turtle vents. City of Simi Valley permit was managed and the roofing contractor work in Simi Valley was completed in three days.
