Ya my cousin who is an engineer and hardly knows which end of a hammer to hold, my at the time 13 year old boy and myself did a 32’ X 48’ 4/12 pitch roof complete with plumbing vents, steel facia and ridge cap. Started 8 am having a beer at 4:30 pm. Nice and straight looks good. The first sheet is the killer have to make ABSOLUTELY sure it is square with roof. other than that super easy
