Roofers typically do the following:
Properly installing and repairing roofs keeps water from leaking into buildings and damaging the interior, including equipment and furnishings. Roofers install or repair two basic types of roofs: low slope and steep slope.
Low-slope roofs are the most common, as they are typical on commercial, industrial, and apartment buildings. The complexity of installing low-slope roofs varies with the type of building. Roofers may install these roofs in layers, building up piles of felt set in hot bitumen over insulation boards to form a waterproof membrane. They also may install a single-ply membrane of waterproof rubber or thermoplastic compound over roof insulation boards.
Steep-slope roofs are typical on single-family homes. Roofers commonly install asphalt shingles, although they may also lay tile, solar shingles, metal shingles, slate, or shakes (rough wooden shingles) on steep-slope roofs.
Roofers also install green technology rooftop applications. These include vegetative roofs, rainwater harvesting systems, and photovoltaic products, such as solar shingles and solar tiles; however, solar photovoltaic (PV) installers typically install PV panels. Plumbers and heating, air conditioning, and refrigeration mechanics also may install solar thermal systems.
Roofers use a variety of tools when installing or repairing roofs. Their tools include roofing shovels, roof cutters, and pry bars to remove old roofing systems and hammers, nail guns, and framing squares to install new ones.
No formal educational credential is typically required for roofers.
Roofers may obtain specific certification to qualify for additional work opportunities or greater pay.
The National Roofing Contractors Association offers certification for experienced roofers. Experienced roofers may become certified in various roofing systems, such as thermoplastic systems or asphalt shingles. Certification as a roofing foreman is also available for experienced roofers.
Most employers require that roofers complete safety certification that meets Occupational Safety and Health Administration (OSHA) guidelines, either before or after being hired.
Some employers require roofers to have a driver’s license to enable commuting to different jobsites.
