How many square feet is my roof.
10 feet by 10 feet 100 square feet.
Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.
It is often compared to slope but is not exactly the same.
1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
For instance if the roof is 1550 square feet then it is 16 squares.
Check that your footage measurements are within this range so you can start off on the right foot.
A square simply refers to a 10 x 10 square of roofing.
100 square feet 1 roofing square 9 290304 cubic meters si unit.
Next you will need to use a roofing materials calculator.
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.
How to estimate roofing materials.
Thus a key element in your project will be the roofing material calculator and more specifically the roof shingle calculator.
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.
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.
For example you will need to figure out the exact number of shingles required to cover the entire roof area.
Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.
You will need to express this size in terms of square feet.
Using an international foot of exactly 0 3048 meters length.
Because each 100 square feet of roof is one.
Once you know this number you can estimate the final price of the materials.
This is simply 100 square feet of roof.
Multiply the square footage of your roof by 1 to get the 10 percent waste allowance.

Convert the area to roofing squares.
The total amount of roofing material you need is 17 300 1 730 19 030 square feet.
It will also give you the perimeter of the shape of the roof.
If the house has an irregular shape measure each part separately figure the separate areas and add them together.
Get the square footage of roof and divide it by 100 and it will give the number of squares you need and for every decimal number over 3 buy a bundle to achieve the amount of material.
To conclude the example if your total roofing area is 17 300 square feet your waste allowance would be 17 300 x 1 1 730 square feet.
