A roof slope of 7 12 is also good and can provide the additional benefit of helping minimize the effects of wind driven rain.
One side slope roof elevation.
We ll call this distance to peak.
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.
Then calculate distance to peak x roof slope where roof slope is the rise run.
For some houses this will be the center of the house for other roof styles it may not be the center.
However from the wind uplift mitigation perspective a 7 12 roof slope can be considered as a two story building due to the higher overall steepness and profile of the roof.
The design is traditional and comes from colonial times.
If this isn t practical then perform the same measurement on the underside of.
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.
This is intended to cover an additional portion to the width of the frame.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
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.
