VentilationVentilation consists of both air intake [soffit vents] and exhaust air [roof vents]. Without efficient ventilation the attic will be unbearably hot in the summer, reducing the life of your shingles. Moisture in the attic can damage the roof deck and contribute to wood rot and mildew. A combination of insufficient venting and insulation can produce ice dams and interior water damage. Insufficient ventilation can also negate your shingle warranties.
A custom calculation will determine the most efficient roof ventilation system.
