Roofers

Roofers typically perform the following tasks: • Inspect problem roofs to determine the best repair procedures. • Remove snow, water, or debris from roofs prior to applying roofing materials. • Set up scaffolding to provide safe access to roofs. • Estimate materials and labor required to complete roofing jobs. • Cement or nail flashing strips of metal or shingle over joints to make them watertight. • Install partially overlapping layers of material over roof insulation surfaces, using chalk lines, gauges on shingling hatchets, or lines on shingles. • Cut felt, shingles, or strips of flashing to fit angles formed by walls, vents, or intersecting roof surfaces. • Apply plastic coatings, membranes, fiberglass, or felt over sloped roofs before applying shingles. • Install, repair, or replace single-ply roofing systems, using waterproof sheet materials such as modified plastics, elastomeric, or other asphaltic compositions. • Attach roofing paper to roofs in overlapping strips to form bases for other materials. • Cover roofs or exterior walls of structures with slate, asphalt, aluminum, wood, gravel, gypsum, or related materials, using brushes, knives, punches, hammers, or other tools. • Waterproof or damp-proof walls, floors, roofs, foundations, or basements by painting or spraying surfaces with waterproof coatings or by attaching waterproofing membranes to surfaces. • Apply reflective roof coatings, such as special paints or single-ply roofing sheets, to existing roofs to reduce solar heat absorption. • Apply alternate layers of hot asphalt or tar and roofing paper to roofs. • Install vapor barriers or layers of insulation on flat roofs. • Cover exposed nailheads with roofing cement or caulking to prevent water leakage or rust. • Smooth rough spots to prepare surfaces for waterproofing, using hammers, chisels, or rubbing bricks. • Glaze top layers to make a smooth finish or embed gravel in the bitumen for rough surfaces. • Mop or pour hot asphalt or tar onto roof bases. • Install attic ventilation systems, such as turbine vents, gable or ridge vents, or conventional or solar-powered exhaust fans.
