What Does "Roof Pitch" Mean?

Roof types vary, including flat, pitched, composite, gable, and more; each of these roof types has a unique roof slope. Roof slope simply refers to how steep the slope of the roof is. There is no one-size-fits-all roof, as standard roof pitches vary by geographic location, climatic conditions, and other factors.

You will most likely see a roof pitch that looks like 4/12. This means that the roof will rise 4 inches for every 12 inches of extension. It's important not to confuse roof pitch and pitch. To get the tilt angle, you have to do some math unless you are a skilled mathematician.

What Is The Angle Of A 4/12 Pitch Roof?

Therefore, a 4/12 roof has a roof pitch of about 18.4 degrees. A 3/12 pitch roof has a pitch angle of about 14 degrees, and so on. Pitch 4/12 is more common. Roofs with a pitch of 3/12 or less are called low pitch. Roofs with a slope greater than 6/12 are considered steep because it is more difficult to walk on the roof.


Find Out How To Determine The Pitch Of Your Roof

It's not difficult. Get a spirit level and tape measure. Make a mark on the 12" level. With one end of the level supported on the ceiling, raise the other end of the level until the air bubbles in the level are even. Immediately after that, start measuring the roof with a tape measure from 12 inches. From this number you can read the slope of the roof.


The slope of the roof is important. By knowing how to make the most of your roof's pitch and maximize its potential, you can extend the life of your home and reduce the number of times you have to call a roofer. Not many homeowners think about it very often (in fact, not many people know that roof slope exists).
