Roof Pitch Calculator Description

Understanding Roof Pitch

Roof pitch, also known as slope or incline, is a critical factor in determining a roof's durability, aesthetic appeal, and functionality. It's defined as the ratio of the vertical rise to the horizontal run. A proper roof pitch ensures water runoff, snow shedding, and structural integrity.

The roof pitch is typically expressed as a ratio (e.g., 4:12) or an angle (e.g., 18.43°). Our calculator simplifies the process of determining your roof's pitch, rise, and run.

For more information on roof pitch and its significance, refer to resources like the Wikipedia article on Roof Pitch or guidelines from the EPA on Roof Pitch and Green Roofs.
