Roofing work is strenuous. It involves heavy lifting, as well as climbing, bending, and kneeling. Roofers work outdoors in all types of weather, particularly when making repairs. However, they rarely work in very cold weather as ice can be treacherous. In northern States, roofing work is generally not performed during winter months.
Workers risk slips or falls from scaffolds, ladders, or roofs, or burns from hot bitumen, but safety precautions, if followed, can eliminate most accidents. In addition, roofs can become extremely hot during the summer, causing heat-related illnesses.
