Then calculate the pitch of the roof by placing a level against it angling the level so the bubble is centered and measuring the distance between the end of the level and the roof.
Width of a roof.
It is often compared to slope but is not exactly the same.
To measure a roof start by measuring the length and width of the building s exterior walls and multiplying them to get the area.
Since pitch is the rise over a 12 inch run divide the run by 12 to get the multiplier in this case 120 12 10.
We multiply the roof length c which is the sum of building length plus the gable end overhangs of the roof by the roof width of slope a that we just figured out above when we computed the hypotenuse of the roof triangle that s why we needed the roof rise number.
Roof pitch calculator results explained.
The total run is the distance from the peak to the edge of the roof which in this case is the total width divided in half which is equal to 10 feet or 120 inches.
In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches.
Angle the angle of a roof is the same as the roof s slope except instead of being.
