If you live in Michigan and own a home, then you absolutely need to know about ice dams. Water intrusion is the number one cause of damage to homes and that damage can be very costly. Ice dams are formed when snow melts on your roof, but freezes when it gets to the eaves (the part of a roof that overhangs the walls of a building). If the ice builds up, it can form a ridge that prevents water from draining. If the water cannot drain properly, there is only one place for it to go, and that is down into your house. This can happen to any roof, regardless of age or condition. The problem lies not with the roof itself, but by heat loss through the attic due to a lack of insulation and ventilation.
