If you're using CertainTeed ridge vents, exhaust vents, and intake vents, the Roofing Ventilation Calculator will give you a quick idea of which products you'll need to order for a particular job. Versions of the app are available for both IOS and Android devices, and include the complete line of CertainTeed roofing ventilation products.
