Measure Roof Square Footage

Along with the roof s pitch you ll use these 2 dimensions to calculate the roof s overall square footage.

Measure roof square footage.

You will need to express this size in terms of square feet. The first step in a free roofing estimate is measuring the roof dimensions. 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. Shingles and other roofing materials such as underlayment are typically measured in squares that are 10 feet long and 10 feet wide with each square measuring 100 square feet.

Just snap a few photos of the exterior of the house with the hover app and our patented technology will take it from there. The easiest way to do this is to simply eyeball them and approximate how long each one is in feet. The roof area is simply 114x18x2 plus 30x18x2 giving 5184 square feet which is perfectly adequate for estimating materials. From the diagrams there are two intersecting roofs measuring 114 feet and 30 feet at the eaves with equal rake of 18 feet.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. Before you do any roofing work you must calculate the roof s square footage to determine how much material you need. Things you will need steel tape measure. Our patented technology calculates square footage and linear measurements for the roof siding windows trim and more.

Once the digital property is complete you will receive detailed exterior measurements and an interactive 3d model to help homeowners design their projects. The calculator cannot account for complex shapes based on a measurement of square footage alone. 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. 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.

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.
