In roofing terminology, the ridge refers to the highest point of the roof where two sloping roof areas meet. This is a critical component of roof design and structure, as it provides essential support and stability while also contributing to the overall aesthetic of the building. The ridge line is typically where the roof vents are located, and it plays a significant role in drainage by allowing water and snow to slide down either side effectively. It is an essential feature in ensuring that the roofing system functions properly and offers longevity.

The other options provide definitions for aspects of roofing but do not correctly define what a ridge is. The open space between roofs pertains more to valleys or gaps and does not capture the idea of intersection. The edge of the roof that hangs over is related to eaves or overhangs, which serve different functions. The angle formed by the slopes refers to pitch, which describes the steepness of the roof but does not identify the roof's highest point. Therefore, understanding that the ridge is specifically where two slopes meet clarifies its significance in roofing.
