I am having a new roof installed and there is an additional item Ridge Vents that I can add to the home - I currently have Gable Vents - no sofits.
I understand that the gables need to be blocked and Sofits added so that there is no short circuiting of air flow directly from gable to ridge.
My issue is this: After searching online for a comparison of energy savings - I get this "Ridge Vents are better and more efficient" Ok I would like to think so as well but I am having a difficult time with that statement. 1: Where are the facts and figures to prove out the efficiency and the savings ?
So here is my question does anybody have any figures , any calculations , any website links for an Actual Comparison of Energy Costs Ridge vs Gables - all things being equal .. same location (neighbors if you will , same cookie cutter suburbian dwelling..).
I am looking for real facts and figures - not um I think so's or seems liek it should be's ..
Any help is greatly appreciated ..
