Simi Valley is an ageing tract re-roof market, not a new-construction market. Most Simi Valley homes were built in the 1960s and the 1980s, with a median construction year in the late 1970s. A large share of roofs therefore sit on homes 35 to 65 years old, at or beyond a first or second re-roof cycle on age grounds alone, so each roof still needs its own inspection.
