Roof Pitch Conversion

If you can give them the exact chart and measurement that you like the look of they can work to those specifications.

Roof pitch conversion.

This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. The charts are there to provide people with an idea of what the actual slope will. Roof pitch conversion charts are very useful for one thing they give you all the information that you need to provide to the professionals. Rise run rise run slope.

First convert the pitch to a slope. How to convert roof pitch to degrees. Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length.

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 measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. To find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the slope. To do this simply convert the rise and run as a fraction to a decimal form eg.
