How To Figure Roof Squares

Roofing pitch for square roof area finally the more complex part measuring your roof s pitch.

How to figure roof squares.

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. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. How do you calculate square footage for a roof. Measure your house at ground level then add in the roof s overhang for greater accuracy.

In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches. The first step in a free roofing estimate is measuring the roof dimensions. A square simply refers to a 10 x 10 square of roofing. If you have a simple gable roof you ll only need to measure and sum up the 2 planes of the roof.

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. Measure the ground dimensions of the house using a tape measure and write down these dimensions. You will need to express this size in terms of square feet. For instance if the roof is 1550 square feet then it is 16 squares.

Roof pitches in degrees. Convert the area to roofing squares. To find the squares divide the overall roof area by 100 and then round up. 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.

L h 2 area calculating an area of a triangle when estimating a roof. This is simply 100 square feet of roof. 2 000 100 20. 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.

Multiply the length by the width to arrive at. 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. Estimate or calculate the pitch of your roof low medium or high. So if you divide your answer of a product of length times height by two you will get the area of a triangle.

It is often compared to slope but is not exactly the same. 1 roof square 100 square feet. Feet then you will have 20 squares. This nominal square footage amount is then multiplied by a factor associated with the roof s pitch.

If your roof is 2 000 sq.
