I headed out to Grand Rapids' Heritage Hill to test a product called "Roof Melt." It's a hockey-puck sized calcium chloride tablet you're supposed to be able to throw up on your roof and prevent the damage that ...

Just wondering what the effects of this is on plants below?

I have been reading this and all I am looking for is an honest "yes it works or No it doesn't" my husband has had heart surgery and can't be working on the roof. In Minnesota the weather is snowy and icy so unfortunately it's a must. So does it work, or not? PERIOD!

Chloride/Chlorine... whatever. A cheap fix vs. chipping ice with a light hand. Detremental to asphalt roofing products... but if you're facing foreclosure,... who gives a cr**. If you plan on living in your home for 10 yrs. or more..., you can do better, cheaper. Rock salt in a sock for problem areas. Keep the ladder handy... all winter. In the end, it all damages the roof. Depends on your budget. Exterior roof temp = outside temp = no ice build up.

Sorry for not posting this yesterday. My being so tight to pay someone to properly vent my roof and me, without the carpentry skills to nail 2 boards to a correct 90deg. angle, I have learned to adapt (old school). If you desire... try yourself with the product (de-icer) of your choice. Pretty simple really.

I use "Pet Safe" granules (however the mix of magnesium/sodium, etc... seems to be a corporate secret). Safe enough for pets to (likely) lick off their feet, the mix is on the mild side and won't destroy shingles right from the get go, yet also keeps melting ice @-10 degrees F. Take 2+ feet of snow off the edge (overhang/eaves) beyond the ice dam. Put 1 lb. or so of the product in a 1 gal. zip lock bag (old socks work faster) and perforate the bag immensely. I use a flat piece of wood with 25+ nails protruding (makes a good meat tenderizer too!). Toss up on the roof behind the ice dam (where the 2+ ft. of snow was removed) every 6-8ft. There are "chloride tubes" one can buy @ most any home supply store, however all I have seen are 20lb.+, somewhat pricey... and that is a lot of (sodium/magnesium) chloride in one area = damage. There is no question the "home" bagged trick will work... it's just getting the right amount in the right area. Experiment. With warmer temps forecasted this weekend, get it up there, start the drainage now and all should be well.

Good luck

The only way that roof melt tablets will work to keep channels open in the ice is to put them in an ice melt sock.

Just curious we have a very expensive metal roof and for the most part everything slides off however we have a reverse gable and the valleys get ice dams all winter. Are these ok for metal roofs? Has anyone ever tried them on metal? Any discoloration or damage left?

I used it last year, and I haven't noticed any discoloration or damage. It seem to work, but not as good as I though it would, or as it was advertised to. I only bought it because I hurt my shoulder, and couldn't safely climb a latter to remove the ice dam. I got it at ace hardware, and you need to be there, soon after it is delivered, or it is gone, they only get a 100 a week, and people grab it right up.

Why do they make the lid so difficult to open. I understand that the design needs to be so as to keep moisture out, but how can you use the tablets if you can't get to them?!?!?

I also purchased Roofmelt to address a large ice dam on the front eave of my home - followed the directions and tossed about 24 pucks within about 1 to 2 feet of the dams - waited all afternoon, evening and when I looked this morning all I saw was the depressions that the pucks made when they landed on the snow. Actually climbed up to the ice dams today and placed the pucks by hand this morning - absolutely nothing has happened...... between yesterday and today have used a whole bucket (60)- in theory it is a nice idea to be able to safely toss the pucks and voila your ice dam problem is solved - Reality is very different. My advice is to look elsewhere for a solution!! Roofmelt is a bust (and a ripoff at $20+)!!!!!

I used this stuff two years ago and haven't had snow on my roof to speak of, since. Course, the bad news is I now have to mow my grass 12 months a year.

I checked the internet and it sounded like a wonderful product. The guy at the store said it was flying off the shelf. It didn't do a thing for me. It was very cold so maybe that was the reason. I went back to using regular ice melt. You have to use "ice melt FLAKES" because the regular granules damages the shingles. Waste of $25.00!!!

. Wow. That is not cool. Joshua has a valid concern. For those who tread lightly and know we are caretakers for this planet. Roofmelt it works as good as you would expect a $20 salt solution to work. I have an old house. One small roof with little pitch has thick ice on it. I used Roofmelt it melts in the puck area it was sitting. Easy to throw. Stayed put for me, one side is flat. I didn't expect miracles. Just some help with the ice. Cheap enough. 60pucks for 20bucks. I have this small 100sq ft roof so I was able to load it up and push the melted stuff off. It eased the load on my roof. It is what it is. Peace People

i've been using it for 3 years now. Works great.... For the thick dams i crush some up in a bucket and spread it along the dam by the gutter. It instantly starts to melt. I have seen no shingle damage over the years.

Fill panty hose with any kind of ice melt and throw it in the gutters. The weight keeps it up there and it works.

I have a fear of heights so no I don't think roofers are over priced. If there job was that easy you wouldn't have called them in the first place

The roof melt I bought didn't do a damn thing. I tossed about half the bucket up on the roof. They finally dissolved when it rained a few weeks later. I even made a small pile of snow in the driveway and put one of the discs in it, nothing.
I emailed customer service and VP Tom O'Malley and told them they should check their quality control because I had a bad batch. CS said they would send me a shipping envelope to return the product for testing. I guess they were just blowing smoke because that was over 6 weeks ago.
I'm glad the product worked for some you but I wouldn't recommend it. It didn't work for me and the company has shown me that they do not stand behind their product. Save your money.
