Metal roof ice dams. The only effective way to solve ice dams is by using a metal roof. When warm indoor air escapes through a rooftop it warms the roof sheathing. Many folks give out false information about this fact.
This will be especially useful if other methods cannot be used for various reasons or are ineffective. As one of the best methods to deal with ice dams problem here in the snow country is to use standing seam metal roofs. Heated roof systems offers you our exclusive patented technology that provides a concealed snow melt mat placed under various roofing material to eliminate ice dams.
By installing a metal roof that has a special coating designed to shed snow and ice causing it to fall off the roof before it has a chance to form into an ice dam you can completely eliminate ice dam formations on your roof in the first place. The water trickles down between the layer of snow and the shingles until it reaches the eave of the roof which stays cold because it extends beyond the side of the house. Typically we experience ice dams on our roofs because of heat loss solar gain or temperature fluctuations creating conditions where snow is melted on the roof and refreezes in the gutters or at the roof edge.
Ice dam myth 1 you need to heat the roof several feet up from the edge ice dam myth 2. Metal roofing does not eliminate ice dams. Its smooth surface can help and the way that the panels interlock can reduce damage from ice dams but there is nothing magical about metal that eliminates ice dams.
Our mats can be placed under asphalt shingles synthetic slate and shake and both standing seam and pro panel roofing giving you the continuous look to the roof edge. Standing seam roof will let the snow simply slide off the roof and ice dams wont be able to form. That should be coupled with improvements in insulation and then ventilation.
Another option to consider is a metal roof. This rise in temperature melts the underside of the layer of snow on top. Metal edging along roof eaves prevents ice dams and roof damage ice dam myth 4.
Stop ice dams by shoveling snow off roof eave edges. The melted snow then moves down the slope of the roof toward the eaves where it freezes into ice. Ice dams are most often the result of inadequate ventilation and insulation in the attic.
Metal roofing is sometimes sold as the smart alternative to heat tape.
