Hidden Hills is a small city in the west San Fernando Valley, with 633 owner-occupied single-family homes by the census count. Properties here are the kind that carry more than one roof: the house, an outbuilding, a garage or a guest unit. A roofing request may cover several structures with different slopes and ages.
A median house built in 1970
The median home was built in 1970. The Census Bureau's 2020 to 2024 estimates stop at their top reported value here, so the median home is worth above two million dollars. Large houses mean large roofs, with valleys, dormers and mixed coverings from successive additions. Measure each structure separately, and ask the assessment to price them as separate lines.
Zone 9 and the rule on a large roof
Hidden Hills is in climate zone 9. For a single-family house, a reroof that goes past half the roof needs steep-slope values of 0.20 for aged reflectance and 0.75 for emittance (SRI 16 also qualifies). On a large house, the half-roof line is a real choice: replacing a part at a time can keep each phase below it, though a full replacement brings the whole roof to one specification.
