Which valley style is unique to slate roofing?

Open gutter valley
Gravel, flood coat, seal coat
Closed valley
Diagonal valley

The correct answer is: Gravel, flood coat, seal coat

The gravel, flood coat, seal coat method is unique to slate roofing due to the specific installation techniques and material characteristics involved. Slate roofs are often installed in a way that requires a more protective and durable finish to ensure proper water drainage and prevent leaks. The use of a gravel flood coat provides added weight and stability, helps with adhesion, and minimizes potential movement of the slate tiles. This method also adds to the longevity of the roof by creating a protective layer that directs water away from the seams of the slate tiles. Additionally, a seal coat is typically applied to enhance waterproofing and further improve the roof's resistance to the elements. Overall, this technique is integral to maintaining the integrity of a slate roof, which is vital given the natural materials that comprise slate.
