Low profile roof vents can be purchased through local building supply companies, Amazon.com, Lowe's, Home Depot and building contractors. Low profile vents made out of special materials, such as copper, may have to be special ordered.
Major home improvement stores and local hardware stores carry low profile roof vents. These vents are used on mobile homes and roofs where vents are lacking in the eaves. They provide better ventilation to attic areas and help to control moisture by letting the building have good airflow. Proper vents can help prevent molds and mildews that can lead to allergic reactions in sensitive individuals.
