The LT® Roof Ice Melt System

LT Installation and Operation Guide

The patented, energy-efficient LT is designed to minimize ice dams and icicles across roof eaves in Class 2 and 3 snow areas.

It is suitable for areas with accumulations from 15″ to less than 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.

The LT system has a superior heated surface to roof contact area ratio making it a true stand-out in the industry. It is so efficient its circuits extend 60% further than the competition.
