Determining Roof Slope
Slope (or pitch) measures the amount of rise your roof has compared to the length. In other words, for every twelve inches of length your roof will rise a set number of inches. The diagram below illustrates a roof that has a seven inch rise for every 12 inches of length thus it has a 7 inch slope or pitch. (also expressed 7 in 12)
An easy way to measure slope is to take level and mark where 12 inches is. (assuming it is longer than one foot) Place the level with one end on the roof and raise the other end until it is level. Next take a tape measure and determine the number of inches between the roof and the spot you have marked on your level. You now have the amount of slope for your roof.
