To install corrugated steel roofing, start at the eaves, overlap panels by one ridge, and secure with screws. Use foam closure strips and flashing to ensure a watertight seal at edges and seams.

Installing corrugated steel roofing starts at the eaves, with each panel overlapping the previous one by at least one ridge. Fasten the panels with screws, ensuring proper alignment and spacing. Foam closure strips should be used under the edges and along seams to prevent water, insects, and debris from entering. Flashing should be installed around chimneys, vents, and roof edges for additional waterproofing.
