On the NRCA Professional Roofing cover is a picture of a guy in a harness, on a roof, of course, Possibly the most uncomfortable looking guy I've ever seen on a roof and that's saying something. Just looking at it from here I can't imagine him accomplishing any work up there whatsoever. He is standing, I grant you, and won't fall off. This is true. That part can't be argued. But, Good Lord, why? What for? I heartily recommend someone smaller with tennis shoes for this job.>>>
