What type of valleys should be enhanced for ice and snow protection?

Open valleys should be enhanced for ice and snow protection because they are typically designed with a channel for water runoff and are often built without the additional cover of roofing material that closed valleys have. In an open valley, the materials used—usually metal flashing or a similar water-resistant product—can significantly reduce the risk of ice dam formation by allowing melting snow and ice to drain more efficiently.

During winter months, the open design allows for better water flow, preventing the accumulation that can occur in closed valleys where roofing materials overlap. By ensuring that open valleys are enhanced with proper materials and installation, you can increase their ability to shed snow and ice, and thus protect the roof from potential damage and leaks that can result from ice damming. Properly maintaining open valleys is essential in regions that experience heavy snowfall, ensuring that they function effectively throughout the winter months.
