You'll find four main types of roofers: shinglers, who generally set up shingles, shakes, tiles, and various nail-on solutions on roofs with 5:twelve pitches or above; steel roofers, who give attention to metallic panels; single-ply or "flat" roofers, who deal with roofs for instance solitary-ply or foam roofs; and "hot" roofers, who get the job done applying tar-primarily based solutions.
