Roof Vents Installation Chicago
Circulating the air in the attic has a number of beneficial effects on the roof and the house in general. In winter, the circulation allows heat to escape, thus keeping the roof colder and preventing ice dams from forming. In summer, attic ventilation does just the opposite. It keeps the attic cooler and reduces the amount of energy you need to devote to air conditioning.
Since roof vent installation requires access to your attic, it can only be completed on the same day as your insulation job.
