ThermaValley+ uses patented technology to stop ice damming on new shingle valleys. It is affixed with an adhesive and does not penetrate the roof deck. This is paired with ThermaShingle+ on the eaves to stop ice damming and clear snowmelt from the roof.
The two sided valley panel secures a double run of UL-listed self regulating heat trace cable in place for highly efficient, direct heat transfer. ThermaValley+ is compatible with all roof materials and is installed directly onto the ice and water shield with an adhesive. This avoids any penetration to the roof deck.
