Rise and run means that a 6 12 pitch roof has 6 of rise vertical for each foot of run horizontal. The gentle slope of a 4 12 pitch roof falls.

Our roof rafter calculator tools are handy for calculating the number of rafters needed rafter length calculator lineal feet of rafter board feed in ridge and sub facia and the total board feet in the roof.
