What is a ridge in roofing terminology?

A ridge in roofing terminology refers to the horizontal peak or line where two sloping sides of a roof meet. It serves as the highest point of a gable roof or similar structures and plays a crucial role in the overall stability and design of the roof. The ridge generally functions as a structural support beam that helps to distribute the weight of the roof and can be a key element in defining the roof's geometry.

While other options touch on different aspects related to roofing, they do not describe the specific function and definition of a ridge. Types of roofing materials pertain to what makes up the surfaces of roofs, measurements of pitch address the steepness of the roof, and decorative features refer to aesthetics rather than structural components. The ridge is fundamentally about the structural support provided at the peak of a roof, making it essential to the overall integrity and design of roofing systems.
