A woven valley is a method of installing shingles in the valley of a roof. The valley is the area where two sloping sections of the roof meet, forming a “V” shape. The purpose of a valley is to direct rainwater and other precipitation off the roof and into the gutters or other drainage systems.
To install shingles in a woven valley, the shingles are woven together in a pattern that helps to direct water down the valley and into the gutters. This is done by laying the shingles from one side of the valley and overlapping them with shingles from the other side of the valley. The overlapping pattern creates a kind of “herringbone” effect that helps to channel water down the valley.
The benefits of using a woven valley in roofing include:
- Better water management: A properly installed woven valley can help to channel water away from the roof and into the gutters, reducing the risk of water damage to the roof and the structure beneath it.
- Improved durability: The overlapping pattern of shingles in a woven valley helps to create a more secure and durable roof, as the shingles are less likely to be lifted or damaged by wind, rain, or other weather conditions.
- Aesthetic appeal: A well-done woven valley can add a decorative touch to the roof, creating a visually appealing effect that enhances the overall look of the building.
Overall, the woven valley technique is a common and effective method of installing shingles in the valley of a roof, providing a range of benefits including improved water management, enhanced durability, and aesthetic appeal.
