HotFlashing Roof Ice Melt System

HotFlashing Roof Ice Melt System

The HotFlashing roof ice melt system prevents ice build-up where a roof slope meets a vertical wall. The HotFlashing panel holds a single run of UL Listed self-regulating heat cable. The heat from the cable is then spread across the panel 6 to 8″. Two types of profile options exist: flat flashing and right angle vertical flashing.

Note: HotFlashing can be used in the valley between roofs or next to the vertical walls of dormers.

Warning: Low cost, constant current heat cable must not be used. Only safety agency UL Listed, self-regulating ice and snow heat cable for structures that is provided with the system can be used.

Flat Flashing

This profile is commonly used in the valley intersection of two adjoining roof surfaces. They can be slid under the existing shingles and secured with commercial grade adhesive. The HotFlashing roof ice melt system panels can be bent or trimmed at the time of installation to clear existing nails or other obstructions. If the existing valleys have a “W” flashing in place, two runs of the panels are recommended. A maximum horizontal melt path of 6 to 8″ from the heat cable can be expected.

Right Angle Vertical Flashing

The HotFlashing roof ice melt system can use right angle vertical flashing to create a melt path next to vertical walls, skylights, dormers, chimneys or other types of protrusions from the main roof surface. THese areas can trap ice and snow and create hidden ice dame that need a drain path.

The panels are available in 3, 6, 10 and 14″ widths. For example, using a 10: total width, the vertical 90 degree flange bend is available at 4″ to create a 6″ vertical flange or at 6″ to create a 4″ vertical flange. Please note the total width measurement includes the horizontal and vertical lengths.
