What is the general rule of thumb regarding amount of ridgevent per 1000 square feet. Is it 4 ft per 1000? I could use your help re enforcing my memory. Thanks.

Paul,


Check this site and see if what you need is there. They have a some pretty good PDF docs that explain all the various type of ventilation, how much, how to calculate, etc.

Sorry I don't have an straight answer. Off the top of my head that number sounds low.

I believe it’s:


1 sq. ft. of combined ventilation per 300 sq. ft. of attic space for soffit/ridge ventilation and...

1 sq. ft. per 150 sq. ft. of attic space for other types of ventilation.
