Metal Roof Guides

The decision depends on panel profile, attachment, corrosion, coating condition, movement, damage extent, access, replacement material availability, and surrounding details.

A standing-seam proposal should identify panel profile, substrate, underlayment, clips, seams, trim, penetrations, ventilation, finish, transitions, access, and closeout.

Metal roof leaks often involve penetrations, transitions, end laps, fasteners, valleys, closures, sealants, or perimeter trim rather than the center of an undamaged panel.

Metal expands and contracts with temperature. Clips, seams, fasteners, panel length, trim, and flashing must accommodate movement without opening water paths.
