 Great service August 6, 2009

I had searched for a while (including brick and mortar businesses) for these roof wire clips. This was exactly what I hoped to find. Price was low and ordering a snap. They arrived very soon, and I've already installed them. They do minimal damage to roof shingles. Just waiting for lots of snow!

After our first large snowstorm this winter. I have found the de-icing cables to be doing their job. Time will tell as the winter progresses, but so far so good. The clips are holding and installation was easy ,just follow the recommended spacing of cables in the installation instructions. A good value!

These parts work fine, and they were shipped very quickly and well packaged.
My story:
The previous owner installed heat cable to try to deal with ice damming, but no clips, so the cables were lying in the gutters but not on the roof. I had considered heat cable on my last house which also had ice damming problems, but decided not to because it sounded expensive and not great results. Anyway, because these were already installed I figured I'd see if I could make them work.
The clips work as promised, but I'm not sure the heating cables do. Now that they're on the roof too, they melt the snow when it's falling, so there's less build up of snow. That's a problem when sun heats the roof or heat leaking from the house melts the snow all at once; that's when the ice dams really build up.
However the cables are not warm enough to melt a lot of ice, although having them on the roof and in the gutters is a better idea than just in the gutters. If they were hotter they might work, but also be a fire hazard and suck up a lot of electricity. But the clips themselves work as promised.
Besides getting up on a ladder and chopping the ice off, which threatens the health of the shingles, I've found the following solution to work best: get some cheap nylon calf-length women's stockings, fill them with ice melt (not salt, but something that won't harm your shingles; I use calcium chloride pellets), tie them in a knot, and toss them onto the roof. Be careful not to breath in the dust from the ice melt, I'm pretty sure it's not good for your lungs.
