More they usually claim that 4 12 is the lowest you can go without any special underlayment.
Roof pitch calculator results explained.
Input the rafter span on the flat eave overhang and pitch of the roof.
Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.
