A person who makes or repairs roofs. A roofer, roofing mechanic, or roofing contractor is a merchant who specializes in roof construction. Roofers replace, repair and install building roofs, using a variety of materials, such as shingles, bitumen and metal. Roofing jobs can be physically demanding because they involve lifting heavy objects, as well as climbing, crouching and kneeling, often in extreme weather conditions.
Curly or rotten shingles, lack of shingles, and blistering are signs that the roof needs attention.
