One of the special things about MasterShield is that we have the capability of installing de-icing or heat cables in your Gutter System. This is an optional accessory and is rarely chosen due to the low prevalence of snow and ice in our area.
MasterShield does not cause nor prevent ice damming. Icicles are not ice damming. Icicles occur when it's cold and there is snow melting from the roof and refreezing when it comes away from the heat loss of your roof. It has nothing to do with the gutter or gutter guard it just means everything is in the process of freeze/thaw and will return to normal when the weather does.
