How to Measure Your Own Roof

Roofs are generally measured in “squares,” which are 10 x 10 areas or 100 square feet. To gather the total area of your roof, simply break it down into its separate planes. For example, a slanted-roof shed would have one plane: the slanted roof. The average gable roof would consist of two planes, which intersect (usually) in the center of the house.

Measure Your Planes And Add Them Up

To measure the area of a rectangular plane, measure the length and width of the plane and multiply those numbers together. Hold onto your result, and repeat the process for the other planes on your roof. Once you have the separate area totals, simply add them together and divide by 100 to get the total number of squares your roof would need.

A: All too often, roof system problems are discovered after leaking or other serious damage occurs. Periodic (twice-a-year) inspections often can uncover cracked, warped or missing shingles, loose seams and deteriorated flashings, excessive surface granules accumulating in the gutters or downspouts, and other visible signs of roof system problems. Indoors, look for cracked paint, discolored plasterboard and peeling wallpaper as signs of damaged roof areas.
