The calculator cannot account for complex shapes based on a measurement of square footage alone.
How to figure out roofing squares.
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.
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.
For example you will need to figure out the exact number of shingles required to cover the entire roof area.
As a result you might need to calculate an estimate of how much it will cost to replace your old roof with a new one.
Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.
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.
To estimate roofing materials start by finding the total square footage of the roof and divide the number by 100 to determine the number of squares in the roof.
Convert the area to roofing squares.
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.
Since it takes 3 bundles of shingles to cover a square plan to purchase 3 bundles for each square.
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.
There are several factors to keep in mind for any estimate.
An important part of any roofing repair or replacement project is being able to accurately calculate the quantity of roofing materials required to finish the job.
The answer is the number of roofing squares for the roof.
Once you know this number you can estimate the final price of the materials.
Singles are often sold in bundles with three bundles equaling one roof square.
Then add 10 to the number to account for waste.
The materials used for the shingles or seam panels the surface area of the roof with a measurement typically in squares and any special features related to the.
To calculate the number of squares or bundles you need you should consider using the measurement method.
A square represents 100 square feet of area covered by shingles.
