Snow Drift and Friction on Metal roofs

I have been researching for a project at work and . I am hoping you might assist us in our research. We are looking for information for snow friction on a metal roof of an unheated building. We have had no luck so far. We also are curious about other research on valley drift. Briefly, the situation we have is an unheated building with a 350 PSF ground snow load and a standing seam metal roof. The roof panels have sustained damage in the field and in the valleys due to sliding snow and ice. If you can assist us or direct us to another source it would be greatly appreciated.

I am sorry but I really do not know of any information of the technical nature that you're seeking. Perhaps some other users of this forum will. As you can well imagine, there are a great number of factors which come into play with this issue. Typically, though, the snow would be shed as soon as the sun came out and a little raidant heat from the sun was reflected back outward by the metal roofing. However, again, there are many variable factors involved as well. If you'd like to, please call me at my office sometime. I'd be glad to discuss this in more detail.
