Calculating Square Footage Of A Pitched Roof

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.

Calculating square footage of a pitched roof.

For example a 4 12 pitch roof that is 100 square feet. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. A roof with a 6 rise for every 12 run has a 6. Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing.

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. Things you will need steel tape measure. When painting a house installing flooring or building a home the square footage of the property is often used to determine cost or materials to be used. 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.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. 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. You will need to express this size in terms of square feet. Roof pitch is used to describe the slope or angle of the roof.

Divide any irregularly shaped areas of the roof into more manageable triangles and rectangles then calculate square footage for those individual elements and add them to get the total square footage. The area calculator can be used to calculate the area of a variety of simple shapes that together can comprise the area of the roof. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area.

The pitch of the roof is the rise over a 12 inch run. The calculator cannot account for complex shapes based on a measurement of square footage alone. 1 acre 43 560 square foot 1 square yard 9 square foot 1 square meter 10 76 square foot 1 square inch 0 00064516 square foot calculating cost per square foot. 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.

100 1 054 105 4ft 2. Multiply by the square footage of a single floor of your house. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. Use our roof pitch calculator to find the pitch of your roof.
