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.
Roof area pitch factor.
The roof pitch can also be determined by staying on the ground.
A roof pitch multiplier also known as a roof pitch factor is a number that when multiplied by the area covered by a sloped roof gives the actual area of the roof.
Surface area of roof area covered by roof roof pitch factor 800 1 12 896 square feet.
For example a standard roof pitch is.
Both metric and imperial measurement systems are displayed in a popup menu over the results area.
Valley hip factor.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
The maths behind this number is that it is the square root of rise run 2 1.
For roof slopes expressed as x in 12 rise in run the roof pitch multiplier is determined by finding the square root of rise run 1.
Get your roof size by using this roof pitch calculator.
Take your area result and multiply it by the pitch multiplier or slope correction factor found in the table above to arrive at the roof s surface area.

Dividing by 12 gives the ratio of inches in rise per distance.
Slope of the roof.
Roof pitch is given as the number of inches in height change over the distance of one foot.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
The overhanging portions on the roof are duly added into the figure.
A roof pitch multiplier also called a roof pitch factor is a number that is multiplied by the area covered by a sloped roof to produce the area of the actual surface of the roof.

Now you re ready to price out the materials.
The surface area of the roof is found by multiplying the number found in step 3 by the number found in step 1.
In other words the surface area is impacted by the slope of the roof.
