Roofers install, repair, and maintain roofing systems including asphalt shingles, metal, slate, tile, and membrane systems. Trade training typically includes 3-4 year apprenticeships. Work includes new construction installation, re-roofing, repairs, and maintenance on residential and commercial buildings. Roofers work with traditional materials (asphalt, clay tile, slate) and modern materials (TPO, EPDM, PVC membranes, metal panels). Typical hourly rates range from $35-$75. Union roofers belong to the United Union of Roofers, Waterproofers and Allied Workers. Safety is critical; all roofers must be trained in fall protection and confined spaces. Specializations include membrane roofing, single-ply installation, slate restoration, and green roofing.
