What term describes the "V" created where two sloping roofs meet?

The term that describes the "V" shape created where two sloping roofs meet is known as a roof valley. A roof valley is an essential element in roofing design and construction, as it directs water runoff from the roof surfaces into the gutters, helping to prevent water pooling and potential leaks.

In roofing terminology, the valley occurs at the intersection of two slopes that come together, creating a trough-like shape that channels rainwater down to the lower sections of the roof and away from the structure. Properly installing and maintaining roof valleys is crucial for ensuring the roof's integrity and longevity.

Understanding the role of a roof valley helps in planning for effective drainage and avoiding common roofing problems, such as water damage or ice dam formation, particularly in regions with significant snowfall or rainfall.
