In response to Chris Turley and the ice / water condition, I may not fully understand the conditions you face Chris but a new product may eliminate the ice dam and the water source coming from the roof. Take a look at this link
http://www.snowgripit.com/ the product, Snow Grip, is an abrasive coating applied to roofs. It holds the snow and ice buildup in place, on the roof, and still allows the melt to reach the gutter. I personally know the patent holder, Mark Blomquist, an architect in the UP and I can assure you of his integrity behind the product. You will also find youtube videos of the product. Ping back if you need furhter info........
