Michael Petruccelli asks; Roof Safety Precautions- An all too common
injury for men over the age of 45 is falling off a ladder. Thus, it is very
important to be cautious and know your ladder when ascending or
descending from roof surfaces. If you are not comfortable on a roof,
you can use binoculars. With that said, no matter how comfortable
you are, it is never recommendedto walk on a roof greater than
6/12 (6 feet rise for each 12 feet of lateral travel; that's 45 degrees).
