Roof Melt, 60 Tablets

I have a high roof line and get lots of snow in Colorado. I use a wood stove in the Winter and get some thick ice dams on the edges of the roof line. I can't get up there to do anything about them so I get this product. I put them into Womens knee high stockings...tie them off with a quick knot the throw them up on to the roof close to the gutter area.... It may take a couple of times to get them positioned correctly but I can get it done. This has been the easiest solution for me to deal with the ice dams when no one wants to climb up there to clear the snow.

I did not know these things existed. We got a lot of snow last winter. 10 plus feet in less than a month. These do not "melt" snow per say but it does melt ice build up. Even a very thick ice dam on roof. Several doscs were bustes up from shipping buut i used the broken and powered pieces as.rock salt on steps. Just toss the discs on roof . Definitely a good putchase

It melted ice and now I dont have ice dam problems

Considering these are supposed to be "pucks" intended to be thrown onto a roof to melt ice dams, it doesn't do any good when half of the contents arrive broken into powdered form. Bad handling during shipping caused the problem. The rating of "3" is the average between "great" and "unusable." Unsure how the vendor could ensure delivery in better condition. I guess my first order which arrived in decent shape was just luck of the draw.

I don't think this stuff works like they say it's suppose to work. I threw a bunch of them up onto my roof and made sure I got one every 12" to 18" apart. They've been up there for about two weeks now and my gutters now have more ice in them then when I put them up and the ice build up on my roof has gone up above where some of the tablets are. How did the ice build up and go over them? They suppose to melt the ice not get covered up by it. I bought these because I don't have any outside outlets to be able to plug in the heat strip stuff so I thought I would try this. Waste of money. I will be installing an outlet outside this summer and doing it the right way next year. I would recommend doing the same to anyone thinking about getting these.

Reviewers need to understand how these are supposed to work. They don't break up ice dams. They undermine them. They are a preventative. They're of vastly more use before the ice dams start holding back melt water! Toss them onto the roof above the freeze line - about as high as you'd normally roof rake the edges, say 5-10 feet up, depending on the roof and normal melt/freeze spots (for a cathedral ceiling, say, with melt / refreeze areas high up the roof, land some at above it in that area). Do so after the snow accumulates, but before there are serious icicles/dams. They will last a for a few storm cycles and ensure that each melt sees a channel cut under the ice dams so water doesn't back up. My roof still developed 5" thick ice dams at the edge of one bad roof area, but it never backed up any water. Use them every 6-8 feet along the roof and use more in any particular trouble spot. You can put them at different heights on the same section just to make sure you have channels for the water to flow if you might get ice forming higher than the roof edge. You can toss a couple extra up in each area for each storm, too, just in case. They are much cheaper than dealing with water incursions.

I love these things. Whenever I forget to rake the roof in time and get an ice dam or two, I toss 10 or 15 of these up there and they eat multiple melt channels in less than a day. I only wish they were square instead of round. You have to chuck them sidearm frisbee-style so that they land flat, otherwise they will roll down the roof and fall into a snowbank where you have to fish them out and try again. And they're expensive as f--*. But they work *perfectly*.

Easy to use and effective. Cost more on Amazon than retail stores but they were out so it was worth it.
