Correspondingly, what is the minimum roof pitch?

The **minimum pitch** for a **roof** is 1/4:12, which translates to 1/4 inch rise to 12 inches of run. However, you can only use this **pitch** with built-up **roofing** or specialized synthetic **roofing**.

One may also ask, what is the normal pitch of a roof? Common **Roof Pitches** The most commonly used **roof pitches** fall in a **range** between 4/12 and 9/12. **Pitches** lower than 4/12 have a slight angle, and they are defined as low-slope **roofs**. **Pitches** of less than 2/12 are considered flat **roofs**, even though they may be very slightly angled.

Simply so, what is the minimum pitch for metal roof?

Most residential **metal roofs** require at least a 3:12 **roof pitch** and have no maximum **roof pitch**. That means there is at least 3” of vertical rise to the **roof slope** for every 12” it goes back horizontally. That is a 14 degree angle.

How is pitch calculated?

The angle, or **pitch**, of a roof is calculated by the number of inches it rises vertically for every 12 inches it extends horizontally. For example, a roof that rises 6 inches for every 12 inches of horizontal run has a 6-in-12 **pitch**.
