Are presidential tl and GAF grand canyon considered to be equivalent? Are they both truly "tri laminated"? Is on a better product than the other? If the "metal roofing alliance is the wrong place to ask this question please stear me to the right place.

Yep, as you suspected, we can't help with these. I suggest posing this question directly to the manufacturers of these products. (Okay, really, I suggest giving up on this question and buying a metal roof!)		Guest User 10/15/2004	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/4333/find/
