We have a standing seam metal roof in snow country. Snow just avalanches off the thing. We've tried all sorts of glue-on snow stops. This spring we had a blizzard and it tore most of them off. If they manage to stay on, they just get twisted out of shape...and snow still avalanches.
I'm working with a roofer who is looking at putting on screw-on snow bars. These are lightweight (same gauge as roof--probably get all bent out of shape?). I'm not wild about holes in the roof but I'm kind of at wits end. We've looked at clamps for standing seam--but they won't work on ours as the seams are loosely-folded, small (1" high) and come to a "V" shape point.
When I'm up in the mountains I see all kinds of snow fences (usually on commercial buildings)--these can look very substantial. Probably also very expensive...but I haven't seen these kinds of products offered.
I've even thought about (don't laugh!) gluing on cut-out portions of asphalt shingles. Perhaps they'd have enough surface area to stay glued on longer? I will definitely entertain new ideas!
Can any of you folks recommend anything I can look at? Our roofer seems to be willing to look at better solutions--I just don't want to go through this year after year!
Thanks in advance!
k.....(Are the holes in the roof, or in my head?
