Ventilation is a system of intake and exhaust that creates a flow of air. Effective attic ventilation provides year-round benefits., creating cooler attics in the summer and drier attics in the winter, protecting against damage to material and structure, and helping to reduce energy consumption. Without proper ventilation installed on a snow covered roof, the heat from the attic can create a thaw-freeze cycle to occur which in turns causes ice dams at the eves(Gutters). Effective ventilation also helps prevent Ice dams. Proper attic ventilation that meets building code requirements is a critical roof system component and a requirement of CertainTeed shingle warranties and is building requirement code for today's building .
