Is a slate roof fireproof?
Slate itself is fireproof. A slate roof is one of the most fire resistant roofs that exist. However, the wood deck under the slate is not fireproof. Often fires will jump from house to house as sparks hit adjacent roofs, igniting the surface if it is a flammable material. Many of the raging fires that engulf hundreds of houses every year would not occur if the houses were covered in slate.
