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.

But there's one important difference: no two gutter protection systems are the same. A quick google search will show you a whole variety of different types of gutter protection systems. I won't delve into the details now (you can read more about each of those in our Product Comparison Guide).

Does the MasterShield need to be removed in order to not void the warranty? a. No, MasterShield isn't fastened to the roof and a careful roofer can work around it. b. If they're not comfortable, they (or we) can uninstall it and then we can reinstall it.
