How To Figure Out Roofing Squares

To calculate the number of squares or bundles you need you should consider using the measurement method.

How to figure out roofing squares.

Then add 10 to the number to account for waste. 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. Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100. 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. There are several factors to keep in mind for any estimate. Since it takes 3 bundles of shingles to cover a square plan to purchase 3 bundles for each square. 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. Singles are often sold in bundles with three bundles equaling one roof square. The answer is the number of roofing squares for the roof. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.

This method is considered the most accurate but you will need to get onto your roof to complete it. 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. 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. Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.

Once you know this number you can estimate the final price of the materials. A square represents 100 square feet of area covered by shingles. 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 calculator cannot account for complex shapes based on a measurement of square footage alone.
