Metal Roofing in Los Angeles County

Why metal shows up in the hills

Homes in the high fire severity zones above Glendale, Altadena, Malibu and the Santa Clarita hills need a Class A assembly. Metal earns that rating with no burnable surface at all, which is why insurers like it there.

Metal also sheds ember piles instead of holding them the way an open tile field can.

Standing seam or exposed fastener

Standing seam panels lock together at raised ribs and the screws hide underneath. Nothing on the surface can back out or leak. It is the system for a home.

Exposed fastener panels screw straight through the face with a rubber washer. They cost less and suit a barn, a patio cover or a shop. Those washers need a look every few years.

What to budget

Standing seam in Los Angeles County runs about 14 to 25 dollars a square foot installed. Exposed fastener runs 8 to 14. Both need a clean deck and good underlayment underneath.

Ask for a high temperature underlayment. Metal gets hot and cheap felt gives up under it.
