I wouldn't waste your time doing this, if your worried about ice backing up in your gutters you can put the heat cable in your gutters and the downspouts, or don't put the gutters on. take the gutters down in the winter and put them back up in the spring, a properly insulated house and if it's vented correctly won't have ice back up, mine doesn't and i built it in 2001-2002. Houses that have ice back up have heat loss and lack of venting to exhaust all the heat, course a well installed roof always helps.
