Yes, you can walk on an American Metal Roof. The texturing and pattern provide the shingles with the strength needed to sustain normal roof traffic. You must step on the upper half of the panels where they taper to rest on the roof deck. If, for some reason, the roof is expected to have a lot of traffic, an optional styrene backer made to rest behind the shingles can be installed. In addition to providing greater rigidity, this backer gives the panel even greater insulating ability.
