Metal, clay, concrete, whatever. As long as it isn't the default combustible shingles made of an oil by-product.

Asphalt shingles account for most residential roofing demand with 81% of the overall market in 2023, according to a new report by The Freedonia Group.

Any fire prone area that puts petroleum based anything on 80% of its buildings roofs is flirting with devastation like this. Hopefully we can learn something out the other side and mandate noncombustible roofing from here on out.
