Here are the most frequently asked questions we’re asked about ice damming on roofs, and how we address these problems with our ice prevention systems:
If you already have ice dams, you need to remove them as soon as possible, or at least melt channels to let any water backed up behind them, drain off your roof. A low tech solution to melting ice channels is to put bags (or pantyhose) filled with calcium chloride at intervals along the eaves of your roof. There is a new product, the Arctic Steamer (video explaining this new product) which can safely melt these channels or the entire ice dam. You (or contractors you hire) should never use an ax or pressure washer , as these will damage your roof.
