Roofers install different types of roofing (such as shingles, single-ply and multi-ply membranes, non-welded sheet metal). They install insulation. They perform inspections, target infiltrations (leaks) and repair roofs. This is a construction trade that requires being in excellent physical condition and manual dexterity. A job as a roofer is suitable for people who enjoy working outdoors and do not suffer from vertigo.
