Built in Simi Valley, Not a Franchise

Simi Valley is an incorporated city in Ventura County, and permits inside city limits run through the City of Simi Valley Building & Safety Division, not through LADBS.

Roof work here is driven by inland heat, concentrated winter rain and Santa Ana wind, and the scope for each home follows its era, roof type and parcel fire-zone status.

For a single-family re-roof in CEC Climate Zone 9, the Title 24 Part 6 prescriptive cool-roof values are an aged solar reflectance of at least 0.20 with thermal emittance of at least 0.75, or an SRI of at least 16, on steep slopes of 2:12 or more, and at least 0.63 with emittance of at least 0.75, or an SRI of at least 75, on low slopes under 2:12. That requirement is triggered when more than 50 percent of the roof area is replaced, which is a different threshold from the City permit trigger, and the parcel's zone should be checked with the CEC zone finder before a product is specified.

Our Mission on Every Roof

Simi Valley contains High and Very High Fire Hazard Severity Zone parcels, but it is not correct to say that all of Simi Valley is Very High. The parcel's zone must be checked in the CAL FIRE / VCFD Fire Hazard Severity Zone viewer, and on a wildland-urban interface parcel the current citation is Title 24 Part 7, the California Wildland-Urban Interface Code, not the retired CBC Chapter 7A. On such a parcel a Class A fire-rated roof assembly is required.

We fix the cause, not just the symptom, and we show you the proof.

What We Stand For

Published regional market ranges include architectural asphalt at $550 to $900 per square and tile re-lay at $900 to $1,600 per square in a Torrance / South Bay 2026 guide, and California repair work most commonly at $450 to $3,200 in a Modernize guide updated 26 August 2026. One square is 100 square feet of roof surface, not floor area, and a written estimate follows inspection of the actual roof.
