How to figure roof squares.

Roofing pitch for square roof area finally the more complex part measuring your roof s pitch. The first step in a free roofing estimate is measuring the roof dimensions. L h 2 area calculating an area of a triangle when estimating a roof. If you have a simple gable roof you ll only need to measure and sum up the 2 planes of the roof.

For instance if the roof is 1550 square feet then it is 16 squares. Measure the ground dimensions of the house using a tape measure and write down these dimensions. 1 roof square 100 square feet. This nominal square footage amount is then multiplied by a factor associated with the roof s pitch.

Convert the area to roofing squares. You will need to express this size in terms of square feet. Measure your house at ground level then add in the roof s overhang for greater accuracy. A square simply refers to a 10 x 10 square of roofing.

Find the square footage of the roof. Estimate or calculate the pitch of your roof low medium or high. Feet then you will have 20 squares. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.

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. 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. This is simply 100 square feet of roof. Because each 100 square feet of roof is one roofing square divide.

How do you calculate square footage for a roof. 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. 2 000 100 20. It is often compared to slope but is not exactly the same.

Measure the length and width of each portion of the roof multiply length by width for each plane and then add the planes together for the total square footage. As an example if your overhang is 12 inches you ll add 2 feet to the overall length and 2 feet to the overall width of the house. If your roof is 2 000 sq. Multiply the length by the width to arrive at.

So if you divide your answer of a product of length times height by two you will get the area of a triangle.
