Water backs up behind the dam and, as it sits on the roof, works its way under the roof covering and flows into the attic. From there it can seep through insulation, ceilings, walls and other areas where it can cause damage.
Proper use of Ice & Water Barrier Products, plus insulation and ventilation, help prevent ice dams – a major culprit when it comes to roof leaks.
