ICE Shield Plug-In Heat Tape Kit for Roofs & Gutters — 60 ft, 5 W/ft, 120V

Electric-resistance heating cables and systems have no polarity. This includes all current WarmlyYours heating elements.

GFEP is the National Electric Code (NEC) required protection for fixed outdoor deicing and snow-melting equipment, which may be accomplished by using circuit breakers equipped with ground-fault equipment protection (GFEP) of 30 mA. It is important to understand that this required equipment protection is NOT the same as a 5 mA GFCI used for personal protection.

WarmlyYours does not recommend installing de-icing cable to remove existing ice dams or heavy snow accumulation. These systems are designed for prevention—maintaining open drainage pathways for meltwater before freezing occurs. Installing heating cables over pre-existing ice blocks is dangerous, inefficient, and will not clear the roof effectively. For best results, install your de-icing system in early fall before freezing weather begins.

NEVER use an extension cord with roof and gutter de-icing cables. Extension cords degrade in harsh outdoor environments, leading to electrical shorts, power loss, and fire hazards. De-icing cables must plug directly into an appropriately rated outdoor outlet with ground-fault equipment protection. If your setup lacks a nearby GFEP/GFCI outlet, contact a licensed electrician to install one safely before operating your heating system.

A 2 pole single-phase 240V circuit works by continuously monitoring the current flowing through both hot wires of the circuit. If it detects even a slight imbalance between the current on each hot wire (indicating a ground fault), it will quickly trip, cutting off power to the circuit. Essentially, it compares each leg of the 240V circuit and trips if they are not precisely equal.

ICE Shield self-regulating roof cable carries a 10-year warranty; plug-in roof heat tape kits carry a 3-year warranty. Service life depends on installation, exposure, and maintenance. Inspect the cable, attachments, and protection devices before each heating season and stop using damaged equipment. Warranty duration is not a guaranteed operating life.

WarmlyYours does not recommend installing de-icing systems on ribbed metal roofs. Ribbed and corrugated panel designs typically lack the flat surface area required to properly adhere standard mounting pads and clips. Without a flush mounting surface, heating cables cannot be safely secured to the roof structure. Always evaluate your roof profile and material compatibility before purchasing your de-icing cable.

No.  Aluminum 3-prong clips can cause rapid galvanic corrosion if they come in direct contact with copper.  WarmlyYours recommends using our Self-Regulating roof & gutter cable fastened with 3-prong Copper clips (ET-CL-CU-P25) and double-sided adhesive pads (ET-VHB-PAD-P25) for this application.

Do NOT use WarmlyYours constant wattage ice shield roof and gutter cable on rubber or rubber-membrane roofs.
