Roof pitch area multipliers.
Square foot of roof with pitch.
Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area.
A 12 in 12 pitch is a steep 45 degree angle roof.
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.
The rise is the distance from the top of a stud wall to the peak of the roof.
Roof pitch is given as the number of inches in height change over the distance of one foot.
See the image below for more explanation on rise run and pitch.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
A roof s pitch is determined by how much it rises for every foot it runs.
Get your roof size by using this roof pitch calculator.
Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.
The answer is the number of roofing squares for the roof.
It is often compared to slope but is not exactly the same.
100 1 054 105 4ft 2.
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.
A square of shingles is the number of shingles needed to cover 100 sq feet of roof area.
The pitch of the roof is the rise over a 12 inch run.
As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles.
A roof with a 6 rise for every 12 run has a 6.
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.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
Dividing by 12 gives the ratio of inches in rise per distance.
The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed.
A 12 in 12 pitch is a steep 45 degree angle roof.
For example a 4 12 pitch roof that is 100 square feet.
Divide your roof pitch by 12.
However shingles are packaged in a way that they are light enough for the average person to carry around.
Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.
Estimate the pitch of the roof.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
