Understanding Roof Pitch
One of the most commonly used terms in roofing. So what does it mean?
Roof pitch (or slope) tells you how many inches the roof rises for every 12 inches in depth.
An Example of a roof pitch would be a “6/12 pitch” which means that the roof rises 6 ” for every 12″ inward towards the peak (or ridge).
There are two suggested ways to measure a roof pitch.
The first is from the top of the roof. Simply mark a level at 12″. Keeping the level balanced measure the distance from the level to the roof surface. If a roof has many layers of shingles your measurement could be slightly inaccurate using this method
The second is to measure from the bottom of the rafters. Measuring the pitch is still the process but you you can measure the roof pitch from three different locations using this preferred method. The underside of a rafter on an overhang at the bottom of the roof, the underside of a barge rafter on the gable end, and the underside of the rafter in the attic.
