About Roof Angles
Roof angle describes the steepness of a roof and can be expressed in multiple formats. Understanding the relationship between pitch, angle, and percentage slope helps with material selection, installation methods, and code compliance.
Slope Classifications
- • Low Slope: Less than 18 degrees (4/12 pitch)
- • Standard Slope: 18-45 degrees (4/12 to 12/12 pitch)
- • Steep Slope: Greater than 45 degrees (over 12/12 pitch)
