The LT Roof Ice Melt System

LT Installation and Operation Guide

We are proud to have our Patented LT in roof ice melt system our family of energy-efficient ice melt systems for roofs. The LT is designed to minimize ice dams and icicles across roof eaves where ice formations begin.

It is suited well for ice dam and icicle prevention in areas with accumulations up to 15″ on the roof and up to 100″ of annual snowfall in light and moderate snow zones. For commercial needs and heavy snow environments where the ultimate performance is desired, we recommend our more robust PRO Roof Ice Melt System.
