HotEdge has introduced an innovative new product that allows contractors to install an energy-efficient ice prevention system on shake, asphalt shingle or composite roofing. The product delivers protection from icicles and ice dams to a wider range of structures.
The HotSheet Roof Ice Prevention System combines a special metal drip edge with a patented rail design, which uses standard 13W self-regulating heat cable far more efficiently than zig-zag systems or heavy extruded aluminum metal designs. Estimated to require less than half the energy of those traditional ice melt methods, the system can be installed on all new shake, asphalt shingle or composite roofs, and can be retrofitted to existing asphalt shingles. No penetration of the roof deck is required.
HotSheet creates a wide slip sheet edge that is directly heated by the cable to help eliminate dangerous overhanging ice that can cause safety risks and building damage. A three-sided raceway compresses a single run of ice melt cable firmly against the bottom of the HotSheet. The energy-efficient design requires less cable than zig-zag systems or serpentine heat tape, saving money on energy usage. The product conforms to the NEC (National Electrical Code) Article 426, and unlike most conventional roof edge ice control systems, it provides access for insertion, inspection and replacement of the heat cable.
Although some existing ice melt systems use metal tracks, the designs typically involve attaching a cover plate over the extruded metal, which creates problems when the ice melt cable expires. “Replacing heat cable is inevitable, given the manufacturers’ estimate of a 10-20 year service life from the self-regulating cables used in these applications,” said HotEdge, Inc. Managing Partner Bronson Rumsey. “Cable inspection, removal and replacement can be a nightmare with many extruded metal systems,” he said. The HotSheet system overcomes this obstacle by designing for easy cable removal and replacement.
“Because this system requires just a fraction of the electrical cable used in competing systems, building owners also benefit from a premium performance option that is less expensive to purchase, install and operate,” Rumsey added.
The HotSheet system is comprised of the panel/drip edge, HotEdge Rail, transition panel and commercial-grade heat cable, UL listed for roof and gutter de-icing. The components can be wired for 120 VAC or 208-277 VAC. National Electrical Code Article 426.28 requires 30mA ground fault circuit protection for all roof ice melting systems. HotSheet is available in 26 gauge galvanized steel, coated with a 20-year siliconized modified polyester paint system in 4 stock color choices, or in .021″ natural copper.
According to a company press release, “HotEdge, Inc. is rapidly expanding into high snow load regions worldwide, fostering relationships with architects, engineers, roofing contractors, material supply companies and licensed electricians. The company is the first and only manufacturer whose metal roof edge ice prevention system is UL Listed, as evidenced by the Certificate of Compliance issued by UL, Cert. # E336195.”
