Our self-regulating heating product is designed to be cut to length at the jobsite by an installer where it can then be end-capped with accessories (sold separately).
However, our constant wattage kits contain heating elements that cannot be shortened or altered in any way.
Electric-resistance heating cables and systems have no polarity. This includes all current WarmlyYours heating elements.
Cable length needed depends on the sizes and areas of the roof that need to be deiced (roof with gutter, downspouts, valleys, and/or dormers). Our best recommendation is for you to give us a call (1-800-875-5285) and we can help you identify what measurements will need to be taken. Alternatively, you can
measure the dimensions of the aforementioned areas and refer to the installation manual to get an idea of how much cable you'll need.
It is not recommended to install this product to remove ice dams that have already formed or for the purpose of clearing the roof of existing ice and snow.
We do not recommend leaving the cable on all year long. It's an unnecessary use of energy to run the cable during warm weather and it could actually cause the heating cables to overheat if they're left on during very warm weather.
Our self-regulating cable product does require 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.
Our constant wattage cable kits do 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.
Overlapping cable is not a problem at all for our self-regulating cable product as its able to regulate its heat output to prevent overheating and damaging the cable.
However, for our constant wattage cable kits, the cable cannot overlap itself or come in contact with itself or any other operating constant wattage heating cable at any time or it could overheat and fail.
Our self-regulating cable product can be used with almost any commonly used roofing material, though you should always check with the roofing material's manufacturer guidelines to confirm.
Our constant wattage kits can't be used on flat roofs, with wooden gutters or downspouts, or on roofs made of the following: slate, stone, metal, ceramic, wood, rubber, or composite (tar and gravel).
Yes, WarmlyYours self-regulating deicing cable may be used in a drain opening or in a trench. It cannot go inside a pipe.
WarmlyYours roof and gutter deicing self-regulating cable loses its power ramp-up ability at about 5-10 years, but it will still work at its rated wattage for years. Properly installed WarmlyYours roof and gutter constant wattage cable usually lasts well beyond its warranty period.
No, typically leaf guards need to be removed for the deicing cable to be installed in the gutter to work effectively.
Chemical roof melt has some serious downsides to consider. Not only are the chemicals potentially harmful for animals and plants, but they're difficult to apply accurately (while staying safe) which means you might not eliminate all of the ice dams. Roof melt's effectiveness, compared to roof melt cable, is more influenced by the ambient temperature and it is possible for the harsh chemicals to damage shingles or other roof components.

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