Shingling a valley is an important step in roofing, as it helps to prevent water from leaking into the home. The best way to shingle a valley is to use a method called “open valley.” This method involves cutting the shingles so that they overlap each other in the valley, creating a watertight seal.
There are several benefits to using the open valley method. First, it is a very effective way to prevent leaks. Second, it is a relatively easy method to learn and master. Third, it is a cost-effective method, as it does not require any special tools or materials.
