A 7/12 roof pitch can also be expressed as 7 over 12 and when you're talking to a roofer, this is the most common way you'll hear it explained because it's easy to say in conversation.
A 7/12 roof pitch is steeper than average, so it may be a little harder and more expensive to install. A benefit of this pitch is that it will shed water effectively without requiring larger gutters.
Another way to express a 7/12 pitch is "7 and 12."
In this pitch, the 7 represents your roof's rise and 12 represents the roof's run.
The roof's incline increases seven feet for every 12 feet of horizontal measurement.
What angle is a 7 over 12 pitch?
Roofs with a pitch of 7/12 are approximately 30.26 degrees, depending on how exact you'd like to be in your measurement.

Above is a roof we replaced in the Greater Boston area last summer. The entire roof is a 7 over 12 pitch, which is a medium steepness. The 7/12 pitch is around the steepness where it starts to get more dangerous to walk on a roof. This roof pitch looks great on two story homes and provide a usable attic space.
