Q: How do I install my Roof Cables?

As temps plummet this winter, ice can accumulate on your rooftop. An ice dam can damage your roof, break your gutters and cause leaks that threaten your home and foundation. In addition to cleaning out your gutters and installing gutter accessories to keep drainage clear, roof cables (also called heat cables) offer added protection from a buildup of rooftop ice dams. Roof and gutter de-icing cables prevent ice from sticking around during sub-zero temperatures. This allows ice to melt and move from your rooftop shingles to your gutters. That water flow reduces the likelihood of roof leaks and shingle damage from hard-packed snow and ice dams. Frost King carries electric roof cables kits in lengths from 30' to 200', each powered by 120V with 7 Watts per foot. These kits come with shingle clips, cable spacers and complete roof cable instructions. These kits are specifically made for inclined roofs with tab shingles. So that your roof cables respond to changing conditions, you may need Frost King's RS-2 Roof Sentry. Assess your entire roof. Where does ice accumulate? Measure horizontal roof sections, depth of overhang, length of each dormer and and length of each downspout. Use the included instructions (download here) to calculate exactly how much roof de-icing cable you need to buy. Install roof heater cables when it's dry outside and it's safe to do the work from a ladder. If you don't have a GFI (grounded) outlet, you may need to hire an electrician to put one close by. Take one end of the cable and begin at the corner of your roof. Run zigzags to create 15" wide triangles, running the cable from the overhang to the warm area of your roof. Secure the roof cable with brackets, affixed to each shingle where the roof cable bends. Run the end of the roof cable along the inside of your gutter and down the gutter's downspout. Plug it into a GFI outlet. Want to see how we install it? Watch DIY podcasters Paul and Brian install roof cables...

Q: Can I use the Heat Cable Kits on a mobile home feed line?

Unfortunately - No. Mobile home lines, like garden hoses, just too flexible and not thick enough to withstand the temperatures of the Heat Cable. Don't do it.

Popular FAQ's

Q: Is the light on the Heat Cable supposed to flash on and off?

No. The Light should be a solid color. If the light is flickering it could mean the cable is not working correctly and you should not install the cable on your pipes.

Q: Do have the printed instructions for the Frost King Automatic Electric Heat Cable Kits?

Popular FAQ's

Q: Can The Heat Cable Kit be placed on a pipe then insulated and covered over with wood or drywall?

No, never install the Heating Cable kits in walls, floors, and ceilings.

Q: How should I secure the Heat Cable Kit to my pipes?

To secure the Heating Cable kit, apply application tape or any good quality electrical tape with a minimum 176 F temperature rating at six-inch intervals. You can secure the Heat Cable Kits with just about any type of tape, but you should stay away from Masking Tape. Masking Tape doesn't have the strength to secure the Cable Kit any length of time, because the adhesive tends to dry out. While it's best to use tape, Cable Ties or Zip Ties will work as long as they are not pulled so tight that they cut into the cable.

Popular FAQ's

Q: Can the Heat Cable Kits be used on plastic pipes?

So, if your pipes are under the house, in an exposed crawl space, or against an exterior uninsulated wall; then it might be a good idea to use the Heat Cables on both hot and cold pipes. Remember, the water in the hot water line turns cold unless it is being used constantly.
