How an Ice Dam actually cause so much damage?
An ice dam is basically a wall if ice that forms on the outside edges, eaves of a sloped roof, as well as in the gutters. Ice dam does not allow the melted water and snow. Snow melts when warms air from the attic rises and runs down your roof. Instead, this water sits underneath when shingles and soon enough starts leaking right inside your home. Not only can this cause roof leaks and rotting of the roof deck, damage your ceilings, walls and insulation, this leaking water also has another dangerous side effect of causing mold growth. Especially if you have family members with allergies or asthma, it is imperative to take care of this issue and not risk having respiratory health problems because of mold.
How Do Metal Roofs Protect against Ice Dam?
