For a 6 1 2 inch in 12 inch slope 6 1 2 6 5 arctan 6 5 divided by 12 arctan 0 54167 28 44 slope.

Roof slope into percentage.

Roof slope expressed as rise run in inches. Roof slope expressed as rise. The table below shows common roof pitches and the equivalent grade degrees and radians for each. Enter the number 0 54167 in the following example and hit the atan button and then the button example.

Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. Let s say it is equal to 1 5 m. 4 76 8 33 grade. Calculate the roof pitch as the proportion of rise and run.

Slope percent amount of rise amount of run x 100. That page also explains the math that. Rise run pitch use this when you express the pitch in percent pitch tan angle use this when you express the angle of the roof pitch in degrees what is the standard pitch of a roof. Pitch rise run 1 5 6 25.

Most roof s have a pitch in the 4 12 to 9 12 range. With a slope percentage of 43 degrees would be. Calculated out this gives an angle percentage of 60. Roof is 6 12 pitch and measures at 2 400 square feet so 2400 x 1 12 2 688 2 88 sqs added for pitch.

Measure the rise of your roof. Many different professions use slope in describing an angle. Calculate the rafter length substituting these values into the following formula. To find the percentage of a slope use this slope percent formula.

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. 3 12 1. 0 or 180 0. Get your roof size by using this roof pitch calculator.

Easy to walk on. Rafter rise run 1 5 6 2 25 36 38 25rafter 38 25 6 18 m. A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof. For example in construction you may refer to the pitch of a roof or the.

The angle percent of a slope with rise of 6 units and run of 10 units is. Slope as grade for an elevation of 1 m over a distance of 2 m can be calculated as sgrade 1 m 2 m 50 slope and roof pitch. 0 12. Divide the rise by the run and multiply by 100.

To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference. Degrees tan 1 43 calculated out this gives an angle of 23 27 degrees. Common roof slopes expressed in rise run and angle slope expressed as grade.
