How To Measure Sq Ft Of A Roof

The square footage of a hip roof area is identical to the square footage of a gable roof of the same size.

How to measure sq ft of a roof.

On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof. The top ridge will be shorter than the one of the gable roof but the four hips will add. Convert the area to roofing squares. The calculator cannot account for complex shapes based on a measurement of square footage alone.

The answer is the number of roofing squares for the roof. Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100. Step 4 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. Make a sketch of your roof before you go out to measure it.

If you have a roof section that s 30 feet 9 1 m long and 12 feet 3 7 m high multiplying those dimensions would give you an area of 180 square feet 17 m 2. To calculate the size of the roof you need to measure the size of the roof as if it were flat account for roof pitch calculate square footage and finally determine how many squares of material are required for the roof the calculator above can handle all of this simply enter the length width and pitch and it will determine the size of the roof in squares. A home s roof is measured in squares. The only difference in this calculation to the one for a gable roof area is the amount of the ridge.

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. For example if a triangle shaped roof plane measures 60 feet along the base and is 30 feet high we have 60 x 30 1 800 feet divided by 2 900 square feet for the triangle shaped plane. 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. X research source measure and mark the square footage of each triangular section carefully as these tend to differ in size.

If you are replacing your entire roof you will need to purchase shingles in 50 squares to sufficiently cover your 5 000 square foot roof. Each square is 100 square feet. Pitch measurement method 2. Calculate the square footage area of a hip roof.

If your roof is 5 000 square feet you will have 50 squares. If this distance measures 4 inches you have a 4 in 12 pitch. The best part of a roofing calculator is that it offers a free insight into the total cost of the replacement roof project on a sq ft basis.
