When outfitting your residential or commercial structure with roofing materials from Everlast Roofing, Inc., it’s important to know the incline, or pitch, of your roof. Pitch is expressed as a ratio of the vertical rise to the horizontal span. In order to know what type of materials will work best for your project and the amount of materials required, you’ll need to find out the pitch of your roof.
Measuring Roof Pitch
To obtain an accurate roof pitch measurement, properly measure the rise and run. Using a tape measure, make a pencil mark 12 inches from the end of a carpenter’s level. Then, you’ll be able to measure slope from an unfinished attic space under the roof. Simply locate a roof rafter board, place the end of the level against the bottom edge and measure from the 12-inch mark vertically to the bottom edge of the rafter. This will give you the rise over run, or pitch. For example, if you measure 4 inches, the pitch of your roof is 4:12.
Finding The Slope and Hip and Valley Factor
Once you’ve figured out the pitch of your roof, you can consult the following chart to discover the slope factor and hip and valley factor.
