Roof Pitch

Roof PitchKnowing the pitch or angle of your roof is helpful when you’re thinking of additions or remodels,  roof repairs or roof replacements.

The roof pitch is determined by the number of inches the roof rises vertically for every 12 inches that the roof extends vertically. If your roof rises 8 inches for every 12 inches of horizontal run, your roof has a 8-in-12 pitch. 

Roof pitch determines what type of roof shingles you should consider. For example, asphalt shingles are not recommended on any roof with a roof pitch of less than 3-in-12, because asphalt shingles rely on gravity and slope for more effective water shedding.

You can calculate your own roof pitch by first taking a 24-inch level, a tape measure and a pencil and going to your attic. Start off by measuring 12 inches in from one end of the level and make a mark. Once you’re in the attic, place the end of the level against the bottom of a roof rafter and hold it level. Then measure vertically from the 12-inch mark you made on the level, straight up against the underside of the rafter. That measurement will be the number of inches the roof rises in every 12 inches.
