Project Description: I installed 4 12" aura roof vents with shingle roof mounting kits (and numerous soffit vents) to ventilate my home's attic. Installation was straightforward and the instructions on your website were all I needed to complete the project. I like the simplicity and maintenance-free aspects of the design. My goal was to reduce summer attic temperatures and save on cooling costs. Since installing them I have noticed a decrease in temperature and increased circulation in the attic. The picture shows the 3 I installed on the main portion of the house.
