How do you calculate square footage for a roof.

How do i measure my roof square footage.

Multiply by the square footage of a single floor of your house. So continuing our example if you ve got a two story house with a total square footage of 2 700 square feet with each floor having. For instance if the roof is 1550 square feet then it is 16 squares. A square simply refers to a 10 x 10 square of roofing.

Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements. 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. 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 calculator cannot account for complex shapes based on a measurement of square footage alone.

Convert the area to roofing squares. Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. It will also show the perimeter of the shape. Measure the ground dimensions of the house using a tape measure and write down these dimensions.

Because each 100 square feet of roof is one roofing square divide. It will also give you the perimeter of the shape of the roof. To find the squares divide the overall roof area by 100 and then round up. Multiply the length by the width to find the area of rectangular sections.

Enter an address or zoom into the map then click on the starting point of your shape. If a section is 120 feet 37 m x 100 feet 30 m its total square footage would be 12 000 square feet 1 100 m 2. After you ve done this you can click along the outer edge of the roof that you wish to calculate the area for. This is simply 100 square feet of 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. How to calculate your roof square footage first measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface. Continue to click along the outside edge of the shape you want to calculate the area of.
