A major concern in prolonging and safeguarding your roof, especially in snow-belt and mountain areas, is ice damming. Ice Dams are created when melting snow freezes on the lower part of the roof, placing roof, walls, ceilings, siding, gutters and down-spouts at risk for costly structural damage. Freezing occurs because the lower part of the roof is cooler than the ridge area. A ridge vent system helps reduce the possibility of ice damming since it delivers a constant flow of air that circulates under the roof. Proper ventilation helps eliminate warmer upper areas and cooler lower areas that create the thaw/re-freeze cycle.
