Each component and feature of the roof is designed to serve a specific purpose. When all of the parts function as they should, what you’ll get is an optimally performing roofing system capable of providing protection and structure for the home. Needless to say, choosing the right style or type of roofing component contributes to a durable roof system.
In this article, gutter installation contractor Tedrick’s Roofing explores the topic of open and closed roof valleys, their differences, and how to choose the right valley type for your roof.
What are roof valleys?
Valleys are the V-shaped areas on your roof where the slopes meet, providing an angle for water runoff. Incidentally, roof valleys are one of the most common areas that have leaks. While there are two types of roof valleys homeowners can choose from, these two are basically constructed the same way during the initial stages. An underlayment is installed over the roof deck. Next, a self-adhering ice and water underlayment material, which now acts as the valley lining, is installed over the first layer.
Whether or not a valley will be efficient at preventing or minimizing a leaking roof issue would be up to how well the installation was performed and whether the materials used were of high quality.
What are closed valleys?
This is the more common choice between the two, mainly due to their aesthetic qualities as well as because they are easy to install. In a closed valley, shingle tabs are installed over the slopes, providing a more seamless look to the roof. However, closed valleys can’t shed water and ice as effectively.
What are open valleys?
Open valleys use high-grade metal sheets and install them over the areas where roof surfaces intersect. While open valleys can affect curb appeal, they are more efficient at shedding ice and water off the roof.
