This page is about the in-city historic portion of Santa Susana only, and that distinction is stated first, because it is the sharpest boundary trap in the Simi Valley project.
Most of historic Santa Susana was incorporated into Simi Valley in 1969, but the remaining Santa Susana / Susana Knolls census-designated place, about 1.1 square miles of unincorporated Ventura County, sits south of the Metrolink Ventura County Line, roughly from Rainey Road to Box Canyon Road. A Simi Valley mailing address does not prove city jurisdiction.
The in-city Santa Susana roofs are the city's oldest stock, in a historic settlement and secondary downtown pocket, with small-scale homes and mixed roofs and a rail-line boundary that decides which building department issues the permit.
For any address near the line, the permit authority is confirmed by parcel, City of Simi Valley Building & Safety inside city limits, Ventura County Building & Safety in the unincorporated pocket, before any scope is written.
Simi Valley is an incorporated city in Ventura County, incorporated on 10 October 1969, and permits inside city limits run through the City of Simi Valley Building & Safety Division, not through LADBS. The City's own FAQ states that re-roofing of more than 10 percent of the total square footage of the roof, or over 100 square feet, requires a permit. A job can therefore need a City permit without triggering other code thresholds, and the permit route, the fee line and the inspection outcome are confirmed at application, not assumed from another city's rules.

A written scope follows inspection of the actual roof, because size, pitch, number of layers, material, access, and permit requirements all change the work. This website does not publish a firm price for this business; published market ranges elsewhere on this site are labelled as market data, not as a quote.
The better choice depends on the house: tract or hillside position, roof pitch, weight the framing can carry, fire-zone status, and ventilation. Compare those factors for the actual roof rather than a single ‘best’ label, and confirm permit and fire-zone requirements for the parcel.
For an active leak, limit interior water damage, avoid walking on a wet or damaged roof, and call (805) 669-9300 to discuss make-safe work such as tarping. Tarping is temporary, not a repair, and no arrival or completion time is promised on this website.
Services on this site cover roof replacement, repair, leak detection, inspection, maintenance, shingle, tile (including lift-and-relay), flat, metal, commercial and residential roofing, plus gutter, flashing, decking, ventilation and skylight repair work. Standalone slate, wood-shake, coating, gutter-cleaning and skylight-installation pages are not offered here.
