   Best thing is to put some salt in a stocking and lay it on the roof running vertically across the point where the ice tends to form (generally right above the wall). You need one every 2-4 feet. Should last all winter in most cases.

   No clue about your product. I can only comment that my brother used some eco-friendly, concrete-friendly, ice-melt product on my mother's concrete front steps and sidewalk for the past two winters.

   The steps and portions of the sidewalk are destroyed, some spalling on the sidewalk, and literally inches thick of concrete have broken off parts of the steps. Steps that were previously solid and unmarred since 1951 when the house was built.

   Have you contemplated adding more insulation to keep your attic and thus your roof colder?

   Insulation and proper ventilation are keys to combatting ice dams .

   Your method is trying to close the barn door after the pony's bolted

   I see somebody using chemicals to de-ice things and I know I will be back to make repairs.

   Deal with the ventilation/insulation issue that is causing the ice damning instead.
