If this isn t practical then perform the same measurement on the underside of.
One side slope roof elevation.
Then calculate distance to peak x roof slope where roof slope is the rise run.
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.
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.
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.
A roof slope of 7 12 is also good and can provide the additional benefit of helping minimize the effects of wind driven rain.
The design is traditional and comes from colonial times.
For some houses this will be the center of the house for other roof styles it may not be the center.
Sometimes the shorter slope is less pitched than the longer side.
Sloped roof house elevation.
A roof with one slope historically attached to a taller wall.
We ll call this distance to peak.
