what are roofs made of?
When you do have to make a choice, the style of roofâpitched or flatâis the first consideration. Materials for a pitched roof include wood shakes and shingles, asphalt shingles, tile, metal, and slate. You can cover a flat roof with tar and gravel, modified bitumen roofing, EPDM rubber roofing, asphalt roll roofing, metal, or PVC membrane.
