First find the slope by finding the tangent of the degrees eg.
Saltbox roof pitch calculator.
To calculate a saltbox roof select saltbox from the roof type dropdown list or select the corresponding button on the toolbar.
Roof pitch calculator will instantly estimate your roof slope from every possible angle.
This online truss calculator will determine the all in cost of your truss based on key inputs related to the pitch width and overhang of your roof.
If you know the angle of the roof in degrees you can find the roof pitch by converting the angle in degrees to a slope then finding the rise by multiplying the slope by 12.
You can calculate slope area rafters length and other dimensions.
It will use the current cost of wooden rafters based on the average price found at home improvement stores.
You can also estimate a roof pitch by eyeballing it from the ground from the gable side with a level and ruler.
Use the diagrams on this page as a reference when inputting rise and run and while interpreting the calculated results.
The roof pitch calculator calculates slope pitch angle and rafter lengths based on input of rise m and run r.
Divide the results by the number of 12 inch segments in your level.
You can also convert roof pitch to degrees at the bottom.
