IceFree Double Valley

The IceFree Double Valley metal replaces  standard “W” metal for metal flashed valleys. The double heated style is great for beating the massive snow storms and eliminates ice dams in the roof valleys. The roof valley itself can be heated for the entire length and many homes are suited for this type of installation.

Each panel comes in a variety of colors as well as copper, aluminum and now Core-Ten for a rustic metal look.

UNA-CLAD Kynar 500 Painted Aluminum, 20 oz. Copper, Core-Ten and other specialty options are available.

Roof Panel Color Options
