Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

Here are a couple examples. Roof pitch refers to the slope which the rafter creates. If you do need to calculate the pitch an estimate or shortcut is usually more practical than measuring the roof s overall dimensions. For a gothic style the rafters must equal the span 60 while an elizabethan style requires the rafters to be longer than the span.

The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. Using ruler and tape you can do it anyway of these ways.
