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.

How do i get the square footage of my roof.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements. The number you get will be an accurate estimate of how much area you have to cover for your roofing project. However shingles are packaged in a way that they are light enough for the average person to carry around.

For instance if the roof is 1550 square feet then it is 16 squares. This is simply 100 square feet of roof. After you ve done this you can click along the outer edge of the roof that you wish to calculate the area for. 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.

Multiply the number of roofing squares for a medium pitch roof by 1 12 to 1 25 or by 1 3 to 1 42 for a high pitch roof to get the square roof area. 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. A square simply refers to a 10 x 10 square of roofing. A square of shingles is the number of shingles needed to cover 100 sq feet of roof area.

Multiply the area by the pitch multiplier to get the roof s square footage. For example take an area made up of a triangle that s 20 feet high and has a base of 40 feet plus a square that s 40 feet by 40 feet. 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.

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. First multiply the length by the width. The calculator cannot account for complex shapes based on a measurement of square footage alone.
