What is a roof's "pitch"?

The term "pitch" in roofing refers specifically to the steepness or angle of the roof. It is usually expressed as a ratio of the vertical rise to the horizontal run. Understanding the pitch is crucial for various reasons, including drainage efficiency, aesthetic appeal, and compatibility with roofing materials. For instance, steeper pitches generally allow for better water runoff and can accommodate different types of roofing materials effectively. This aspect of the roof is vital when planning construction or renovation, as different angles may be more suitable for specific environments or climates. The other options, while related to roofing considerations, do not accurately define the concept of "pitch."
