Mono pitched roofs pitched here means a roof plane rather than a slope and implies it is not a flat roof mono pitched roof shed skillion lean to roof 2.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
Then calculate distance to peak x roof slope where roof slope is the rise run.
It has the upper ridge at the peak 2 slopes on each side and the added characteristic of one side s slope being noticeably longer.
Measure the horizontal distance from one of the side walls of the house in this elevation view to where the peak of the roof will be.
Sloped roof house elevation.
A roof slope of 7 12 is also good and can provide the additional benefit of helping minimize the effects of wind driven rain.
This is intended to cover an additional portion to the width of the frame.
The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.
