Roofers may also waterproof walls and floors.
Most roofers acquire their skills by working as helpers for experienced roofers.
Some roofers train through 3-year apprenticeship programs. A high school education or its equivalent is helpful, as are courses in mechanical drawing and basic mathematics. Most apprentices are at least 18 years old. The accident rate in the roofing industry is the highest in all construction. Roofers work outdoors in all types of weather.
