In cases where a roof has a complex shape such as in the image to the right measuring the dimensions and areas of each part of the roof to calculate total area will result in a more accurate measurement of area.
How to figure how many square a roof is.
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 square represents 100 square feet of area covered by shingles.
Feet then you will have 20 squares.
The square footage of a hip roof area is identical to the square footage of a gable roof of the same size.
The only difference in this calculation to the one for a gable roof area is the amount of the ridge.
Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.
You will need to express this size in terms of square feet.
Divide the length of your roof by the width of the metal.
Singles are often sold in bundles with three bundles equaling one roof square.
Now it s time to convert square feet into roofing squares.
This is the number of metal panels needed for one side of the roof.
To calculate the size of the roof you need to measure the size of the roof as if it were flat account for roof pitch calculate square footage and finally determine how many squares of material are required for the roof the calculator above can handle all of this simply enter the length width and pitch and it will determine the size of the roof in squares.
1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
Finally the more complex part measuring your roof s pitch.
If your roof is flat or has no more than a 3 in 12 pitch you can calculate its total square footage by simply multiplying the length by the width.
Estimate or calculate the pitch of your roof low medium.
The calculator cannot account for complex shapes based on a measurement of square footage alone.
To properly calculate how many bundles of shingles are needed to roof your home you need to calculate the total square footage of the roof and convert it to squares.
If your roof is 2 000 sq.
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.
In our example we will use 24 inch standing seam roofing so we will divide 360 inches by 24 which equals 15.
For example standing seam metal roofing is 24 inches wide.
2 000 100 20.
This is pretty simple.
Roofing pitch for square roof area.
Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.
Calculate the square footage area of a hip roof.
The answer is the number of roofing squares for the roof.
The first step in a free roofing estimate is measuring the roof dimensions.
