Cover roofs of structures with shingles, slate, asphalt, aluminum, wood, or related materials. May spray roofs, sidings, and walls with material to bind, seal, insulate, or soundproof sections of structures.
<ul><li>Inspect problem roofs to determine the best repair procedures.</li><li>Remove snow, water, or debris from roofs prior to applying roofing materials.</li><li>Set up scaffolding to provide safe access to roofs.</li><li>Estimate materials and labor required to complete roofing jobs.</li><li>Cement or nail flashing strips of metal or shingle over joints to make them watertight.</li><li>Install partially overlapping layers of material over roof insulation surfaces, using chalk lines, gauges on shingling hatchets, or lines on shingles.</li><li>Cut felt, shingles, or strips of flashing to fit angles formed by walls, vents, or intersecting roof surfaces.</li><li>Apply plastic coatings, membranes, fiberglass, or felt over sloped roofs before applying shingles.</li><li>Install, repair, or replace single-ply roofing systems, using waterproof sheet materials such as modified plastics, elastomeric, or other asphaltic compositions.</li><li>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.</li><li>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.</li><li>Attach roofing paper to roofs in overlapping strips to form bases for other materials.</li><li>Install vapor barriers or layers of insulation on flat roofs.</li><li>Cover exposed nailheads with roofing cement or caulking to prevent water leakage or rust.</li><li>Apply alternate layers of hot asphalt or tar and roofing paper to roofs.</li><li>Apply reflective roof coatings, such as special paints or single-ply roofing sheets, to existing roofs to reduce solar heat absorption.</li><li>Smooth rough spots to prepare surfaces for waterproofing, using hammers, chisels, or rubbing bricks.</li><li>Glaze top layers to make a smooth finish or embed gravel in the bitumen for rough surfaces.</li><li>Mop or pour hot asphalt or tar onto roof bases.</li><li>Install attic ventilation systems, such as turbine vents, gable or ridge vents, or conventional or solar-powered exhaust fans.</li><li>Apply gravel or pebbles over top layers of roofs, using rakes or stiff-bristled brooms.</li><li>Install skylights on roofs to increase natural light inside structures or to reduce energy costs.</li></ul>
