I have bundles of shingles left over from my house/shop project. Although they were stored, covered with tarp, some shingles on top have some water staining. It doesn't bother me and you can see for yourself what they look like on the side of my shop. Should fade with time.
I have two lots for sale.
4 Bundles = 1 Square

$350 for ALL
