Roofers

Typical tasks

From O*NET 31.0. Core tasks first. Few of these tasks have a benchmark today.

• Inspect problem roofs to determine the best repair procedures.
• 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.
• Cover exposed nailheads with roofing cement or caulking to prevent water leakage or rust.
• Apply reflective roof coatings, such as special paints or single-ply roofing sheets, to existing roofs to reduce solar heat absorption.
• Remove snow, water, or debris from roofs prior to applying roofing materials.
• Cut felt, shingles, or strips of flashing to fit angles formed by walls, vents, or intersecting roof surfaces.
• Install vapor barriers or layers of insulation on flat roofs.
• 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.
• 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.
• Set up scaffolding to provide safe access to roofs.
• Cement or nail flashing strips of metal or shingle over joints to make them watertight.
