Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.
How many feet is my roof.
The first step in a free roofing estimate is measuring the roof dimensions.
3698 sq ft with predominant 10 12 pitch.
According to your calculator my actual square feet of house is 4807 5 numbers of squares needed is 53.
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.
You will need to express this size in terms of square feet.
See the image below for more explanation on rise run and pitch.
Estimate the pitch of the roof.
Each time you add points the area will update and there is a box below that will convert this into acres meters kilometers miles and finally square feet.
The numbers i used are based on the proposal from my roofer.
Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.
A 12 in 12 pitch is a steep 45 degree angle roof.
Keep in mind that the average size of a roof is 1 700 square feet so your total will likely be 10 higher or lower than this figure.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
It will also give you the perimeter of the shape of the roof.
It is often compared to slope but is not exactly the same.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
