Installing a water and ice-dam protection membrane along the eaves helps control problems resulting from ice damming but does not prevent it. Construction for effective control of ice dams has to address the root causes and those typically lie below the roof deck. For typical residential construction, air sealing the ceiling plane, insulating the attic floor and providing balanced attic ventilation are the key components for an effective ice-damming solution. Because two of the three generally do not fall within the scope of roofing work, you may choose not to undertake all the work. In any case, inform clients about the complete scope of work needed to prevent ice dams.
