Call Today! I am a Wisconsin native and have been in the building trades most of my life. I spend my time between Breckenridge , Colorado and my home town of Cornicopia. I teach skiing in Colorado, and have experience in harsh winter conditions at. 10,000 feet altitude. I have installed several Heated roof systems and am impressed with the results. Forget the unsightly look of external heat cable, and the "other" metal shrouded heat cable. Heated roof systems silicon heat mats, are the only viable long term solution to ice dam problems. Please call me if I can meet with you and help problem solve your winter headache problems.
