Hi guys. Several months ago I read in this forum in one of the posts a chart of sorts with factors to figure the area of a roof from the square footage of the floor directly under it. There would obviously be a different factor for each different pitch. I have searched the archives and cannot find it. I believe it was in a post with a heading not necessarily related to this specific subject. If anyone would know where this is or maybe have a chart like this, I would appreciate the information.
