For example your chimney is exiting 20 away from the peak and you have a 6 12 pitch roof.
Divide the rise by the run 5 12 0 4166667.
Using the slope 6 12 we need to rise 6 inches ten times to get to the peak.

So 15x6 90 or 7 5.
Then multiply by the 6 which comes from the pitch.
We can simply take half the base length which in this case would be 1 2 of 30 15ft.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
Thinking my ridge beam height should be 49 1 2 inches from the top of the garage walls with the 6 12 pitch.
