Heat Tape Pro is a self-regulating cable that adjusts its power usage with temperature changes, consuming more energy in colder conditions and less when warmer, which makes it self-regulating. This feature ensures it's an effective, long-term solution for preventing ice dams by creating melt pathways on your roof. It's also versatile, suitable for roof, gutter de-icing, and protecting pipes from freezing, working on pipes as small as ½ inch in diameter across metal and plastic materials. Remember to include necessary installation accessories like Roof Clips and Downspout Hangers for best results.
