Hello, we're sorry for your experience, however, this product is made specifically for use with GAF shingles, in particular Slateline Royal Slate and Camelot II Royal Slate. Did you attempt to use them with other shingles? While we apologize for the difference in image versus actual product, if there was a mis-match on your roof, we'd like to know more. Please give our technical team a call at 1-877-GAF-ROOF.
