Sizing a ridge beam

Roof Framing and Pitch. Roof pitch - sometimes called slope - is represented as X in 12. For example, a roof pitch that rises 6 inches for every 12 inches of run is said to have a six-twelve pitch.. Once the rafter size has been determined (2x6 in this example), the next step is to determine the Pitch(X) of your roof so that you can layout and cut the angles on your rafters.

Sizing a ridge beam. You can size your ridge by being over conservative, using the 60 psf snow load, unfactored by ASCE-7, a dead loading (from what you've given) of 12 psf, thus totaling 72 psf. With your tributary area given, your beam needs to be sufficient for handling 288 plf for its 14 foot span.
