I'm building an addition to a old cottage with a raised foundation and a Gable roof. The addition will have a gently sloping metal roof. The roof will start just under the existing roof and and slope down to the new back wall. It seems to me, the maximum depth of the room, or span of the rafters will be determined by:
Minimum slope of the roof
Minimum ceiling height (open beam ceiling) at the back wall
Crawl space under raised foundation
Knowing those 3 measurements I should be able to figure out what the max span of the rafters to the rear wall can be. My question is, if I'm thinking right, what are the above measurements? Thanks!
