What Downey Homeowners Should Know Before a Reroof
Downey answers the permit question directly in its own residential re-roof handout: yes, a permit is required, and no roof recovering or replacement work may start before one is obtained. Permits come from the Building & Safety Division of the Community Development Department, on the first floor of City Hall at 11111 Brookshire Avenue.
The City scales the requirement to the size of the job. Repairs covering less than 10 percent of the roof area or 100 square feet, whichever is less, may be done without a permit. Between 10 and 50 percent, a permit is required and the replaced portion must meet current code. Above 50 percent, the entire roof must meet current code. On layering, Downey states that a new covering can only go over a single layer of existing roofing, and that a roof already carrying two layers must be stripped to the deck first. Not more than one overlay of asphalt shingles may be applied over an existing asphalt roof, and no new covering may be applied over wood shakes. Two inspections are named: a sheathing inspection after new sheathing goes on but before it is covered, with the roofing material on site, and a final that checks the minimum Class B covering, attic ventilation of at least 1:150, flashings and crickets, and the smoke and carbon monoxide alarm certification. Materials over six pounds per square foot need stamped structural calculations, and tile is limited to pitches of 3:12 or greater.
Downey’s housing stock explains why the layer rule comes up so often. Census figures for 2020–2024 give a median year built of 1959, with 38.6 percent of all units dating from the 1950s and 70.0 percent built before 1970.
Most of Downey falls in California Building Climate Zone 8 under Title 24. The City notes that the area north of Vista Del Rio is Zone 9, so the applicable cool-roof values depend on where in the city the property sits.
