There is no doubt that an Eagle concrete tile roof is beautiful, sustainable and durable. However, did you know that the inherent energy efficient properties and R-value can be further enhanced by upgrading to a Ventilated Roof System?A tile roof is fundamentally air permeable, yet local installation codes and practices can either enhance or detract from this very important performance characteristic. A Ventilated Roof System encourages additional airflow underneath an Eagle concrete tile roof. The impact of the additional airflow may include an extended lifespan for the underlayment, and components, as well as an energy saving reduction in heat transfer through the attic into the living space.A Ventilated Roof System is comprised of three key elements:1. Intake: Air enters the roof system through a perforated metal eave closure. A standard eave closure offers a small drainage opening and does not encourage air intake.2. Airflow: Air travels from the eave under the roof tiles. The velocity of airflow under the roof tile is elevated by using Eagle's Arched Battens. Arched Battens are produced from graded lumber and are available in natural or treated wood. Their single piece construction ensures structural rigidity and does not require the use of special raised battens.3. Exhaust: Proper air exhaust occurs in the upper third of the tile roof system. Exhaust can be accomplished via ventilated tapes at the ridge, or with profile specific O'Hagin Roof Vents.
