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.

WarmlyYours self-regulating roof and gutter de-icing cable can be used on rubber or EPDM (Ethylene Propylene Diene terpolyMer) roofs.

The primer that WarmlyYours sells is specifically for adhering clips to EPDM or rubber roofing.

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 self-regulating cable is suitable for use on standard asphalt or wood shingles, angled cedar, tile or terra cotta, slate, flat membrane-type (rubber or EPDM) roofing, and metal roofing. For attaching, the same clips are used for both slate and cedar roofing. Always check local codes for approved methods of heating roofs and gutters.

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.

WarmlyYours offers a conversion kit (SR-PLUG-KIT) to enable a plug-in requirement. This kit includes ground fault equipment protection (GFEP). The receptacle must be 120V, grounded, and approved for wet locations if located outside. The self regulating cable must not exceed 140‘ in length.

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.

Was this helpful? Yes No

WarmlyYours self-regulating cable can rest in the bottom of the drain. Some people put them on the AIR-STAT to control operation.

Was this helpful? Yes No

Yes, WarmlyYours self-regulating deicing cable may be used in a drain opening or in a trench. It cannot go inside a pipe.

Was this helpful? Yes No

Triangles are spaced 24" apart.

Was this helpful? Yes No

No, typically leaf guards need to be removed for the deicing cable to be installed in the gutter to work effectively.

Was this helpful? Yes No

Self Regulating cable is not designed for snow load removal. It is designed for deicing in scuppers, roof overhangs, gutters, downspouts, trench drains, etc.

Was this helpful? Yes No
  • Overlapping WarmlyYours self-regulating cable is possible because self-regulating cable regulates heat output to prevent overheating and damaging the cable.
  • Overlapping WarmlyYours constant wattage cable is not possible because it is on all the time and cannot come in contact with itself or any other constant wattage heating cable, as it will overheat and fail.
  • Self-regulating cable requires the use of a control and/or a sensor to operate. WarmlyYours offers a variety of controls ranging from a basic manual control to our premium option that provides the ultimate in convenience and hands-off operation.
  • Constant wattage cable does not require a thermostat/controller and can be connected to an outlet throughout an entire winter, during a single snow event, or whenever deicing is needed. An optional plug-in thermostat can be used if desired.
  • Self-regulating cable is designed to be cut to length at the jobsite by an installer where it can then be end-capped with accessories (sold separately).
  • Constant wattage cable cannot be shortened or altered in any way.
Was this helpful? Yes No

As the names imply, constant wattage cable uses fixed wattage output per linear foot and does not automatically adjust in response to temperature changes. Self-regulating cable is manufactured with a resistance matrix placed between its 2 buss wires that varies the ohms resistance per linear foot to automatically adjust in response to temperature changes. Learn more about this in our blog Self-Regulating vs. Constant Wattage Heating Cables.

Ice Shield is 120V or 240V and outputs 5W/ft, and is designed for roof and gutter deicing.
PRO-Tect is 120V or 240V and outputs 5W/ft, 8W/ft, or 10W/ft, and is designed for pipe freeze protection.

Was this helpful? Yes No

Two good reasons for this:  

  1. Constant Wattage cables maintain a consistent heat output regardless of the surrounding temperature. Metal roofs, being highly conductive, can cause rapid temperature fluctuations which can lead to overheating and potential damage to the cable's insulation, potentially causing a fire hazard.
  2. The UL approved installation method requires self-regulating cable for metal roofs.  If not installed per UL guidelines, there is no listing and thus no warranty.
