Roofer
A roofer or roof mechanic is a construction worker who specializes in roof construction. Roofers concentrate on the application of materials that waterproof and/or weatherproof buildings, designed material—as a substrate for the roofing materials to be installed on, the rafters, beams, and trusses are the frame or skeleton for the roof to be built upon. Roofers must be able to work, have good motor skills and possess general carpentry skills.
Throughout the world
In Australia this type of carpenter is called a roof carpenter and the term roofer refers to someone who installs the roof cladding (tiles, tin, etc.).
In the United States, the most common roofing material is asphalt shingles. In the past, 3-tab shingles were used; nowadays, "architectural" or "dimensional" shingles are becoming very popular.
Depending on the region, other commonly applied roofing materials installed by roofers include concrete tiles, clay tiles, natural or synthetic slate, single-ply (Primarily EPDM or Rubber, PVC, or TPO), rubber shingles (made from recycled tires), glass, metal panels or shingles, wood shakes or shingles, liquid-applied, hot asphalt/rubber, foam, thatch, solar tiles, and specialty roofs like Duro-Last. "Living roof" systems, or rooftop landscapes, have become increasingly common in recent years in both residential and commercial applications.
