Ice peals Vertical Panel | Ask The Experts Forum

Guest User 8/17/2004	I have a vretical panel roof with 6-12 pitch and valleys. In the valleys the snow and ice build up (33' run) peals the paneling at the bottom on the short side of the valleys. It is a slow glacier action. I have installed snowjacks, about a foot above the valleys, but apparently not enough, as last winter's snow has removed many- even though they were screwed and attached with adhesive. Some broke at the 90 degree bend, some were just ripped off, screws and adhesive also! So- will additional snow jacks help? I was thinking about maybe three layers, where the run is so long- several feet apart along the 33 foot run. I have R-36 insulation, good venting at eaves.

Guest User 8/17/2004	More snowguards might help to hold the snow and keep it from converging so violently in the valley. That is a pretty long valley. If this is a recurring problem, I would consider "opening up" the bottom of the valley with a large custom-formed "pan flashing" rather than the standard width valley.
