Bob,If your material is folded up in a box,you will regret using it.That always bothered me about Mac's,the roofing came folded,and you NEVER get the fold marks out.I have a piece hanging behind the woodstove in the cellar.The owner bought it from Mac's,and opened the box after about a year had passed.I have had it hanging in the heat for at least three years and it still has every fold in it.It costs a lot more to ship it wrapped around a tube,(UPS oversize) compared to a small box,but what good is a small box of something unuseable?
