I'm planning a very simple structure, and want to use a load bearing ridge beam (to avoid collar ties, etc...). The size of beam my lumber yard recommended seems rather large to me. I'd like to get a second opinion. Are there any on line tools a non-professional could use to do this calculation?
It is a simple gable end structure. 14' long, 8' wide, with an 8:12 roof, and I'm in Minnesota, so snow load is a definite consideration.
