Roof Deicing

Self-regulating cables for the roof and gutter heating, melt snow and ice, to keep a drain path for water to flow freely away from the house.

Roof & Gutter Heating

Freeze and thaw cycles create ice dams that can quickly damage or even destroy roof coverings, gutters and downspouts. Pooled water behind the dam may leak into the building, causing water damage, or climb over the ice-filled gutter, forming icicles. The resulting water damage to your home’s interior can be many times more expensive to repair than the roof or gutter itself.

Warmup provides self-regulating electric cables for the roof and gutter heating, that automatically adjust their power output to compensate for temperature changes.

The self-regulating heating cable is ideal for both commercial and residential use. A full range of controllers, sensors and accessories is available, guaranteeing the optimal solution for the roof and gutter heating.

Warmup tip: Use the SB-190 water and weather-proof adhesive sealant to fix the roof clips and protect roof shingles. Our roof clips have an extra coating that prevents them from damaging roof shingles.
