I know to the experienced roofer, this is a stupid question, but I just wanted to be sure. Do Owens Corning architectural shingles and GAF Timberline 30 architectural shinlges get installed the same way? The reason I'm asking, is because my roofer usually uses Owens Corning, but I want to get GAF to match our shop.
Thanks for your help.
