We have plenty of flavor holds on our wall and this is by far the biggest. Obviously, it's not going to be much of a challenge to hang onto it on anything but steep overhanging walls because it's a huge jug. I have not tried it yet, but I think this thing would be crazy hard on a roof but maybe just possible because of the 1/4" lip. Like a big double crimp on a roof. Leave a review if you try it an succeed :-) Atomik flavor holds are always fun and functional. Thanks Atomik for being so creative!!
