What is the definition of a woven valley in roofing?

The definition of a woven valley in roofing refers to a technique where shingles from both sides of the valley interlace. This approach creates a barrier against water intrusion, as the overlapping shingles help to direct water towards the gutter while also adding to the aesthetic appeal of the roofline. By intertwining the shingles, a woven valley provides a seamless transition between different roof sections, contributing both to functionality and visual continuity in the design.

In this case, the interlacing of shingles is vital because it not only enhances the roof's appearance but also improves its waterproofing capabilities, minimizing the risk of leaks at the valley where two roof planes meet. Other options may touch on important aspects of roofing, but the defining characteristic of a woven valley specifically revolves around the technique of interlacing shingles.
