Description

Current building codes typically call for attic ventilation to minimize condensation on the underside of roof sheathing. Summer cooling of attic air, minimizing ice dams, and extending the service life of the roof materials often are cited as additional benefits of attic ventilation. In fact, most asphalt shingle manufacturers warrant their products only for ventilated roofs.
