A roof replacement can be one of the biggest home improvement projects you’ll probably ever tackle. Various problems and issues tend to surface more frequently the more your roof approaches the end of its life span. However, you can stave off getting a full replacement by making sure that your roof is installed correctly from the get-go.
Roof construction can be very technical and not many homeowners understand its many aspects. However, familiarizing yourself with a few of the most important parts can be helpful as you make decisions on your roof replacement. Let our experts at Silver Leaf Contracting explain two of the most misunderstood concepts in a roofing system.
Closed Valleys
Before asphalt shingle roof companies install the shingles, they start out by building a sturdy roof deck. The decking is covered by an ice and water shield as well as a protective underlayment. The valleys in your roof are particularly prone to water penetration which is why a second layer of lining is installed to keep it well-covered. This is known as a closed valley installation.
Open Valleys
The only difference between closed and open valleys is the secondary lining that protects the intersection between two roof panels. In an open valley installation, the shingles themselves are extended over the valley and serve as its main protection against moisture instead of another layer of flashing.
Which Is Better?
While closed valley shingle roofs are the more popular choice, there are also benefits to choosing open valley installations. However, considering the amount of exposure your roof gets to the elements, you’ll definitely want to give it as much protection as closed valley installations can provide.
