What Size of Roof Mounted Attic Fan Do I Need?

Roof-mounted attic fan is based on the sizes which are rated in CFM. CFM is the abbreviation of cubic feet per minute. If any attic fan has been rated at the level of 1,000-cfm, it means that it can somehow exhaust 1000 cubic feet of air per minute.

It has been recommended that your roof-mounted attic fan should exhaust your entire attic at least 10 times as per hour. And HVI often provides a simple rule of thumb for selecting the minimum range of CFM for your attic size.
You have to simply take upon the attic size in square feet and then multiply it by a 0.7 multiple.

And if your roof is dark-colored or if it is steep, then it will be increased to a 0.805 multiple. If your attic is almost 1500 square feet, then you have to multiply it by 0.7 to get 1050-cfm.
