When it comes to the topic of the roofing system, some homeowners tend to think that it’s only composed of the shingles, the component that gives it its outer appearance, and the roof deck, which holds the roof up. In reality, however, it’s actually composed of different pieces, one of which are the valleys. According to experts, you can choose between two different kinds of valleys: open and closed.
Here are the differences between the two.
An open valley is a sheet of metal that is fastened to the roof via the joints. This is usually done before the shingles are installed on the roof. Afterwards, the shingles will be cut and sealed where they overlap the open valley. As always, it comes with its own set of advantages and disadvantages. For example, it can shed ice and water faster, minimizing the granule loss that can cause your roof to deteriorate early as a result. They also have a certain aesthetic appeal if installed properly and is easier to fix if it sustains damage.
In terms of disadvantages, on the other hand, you need to keep in mind that open valleys can be more costly to install as they require additional materials and special equipment for the installation.
Closed valleys are seen on most homes. This is due to the fact that they are easy to install and aesthetically appealing. Unlike open valleys, they do not require extra materials and equipment to install, and are very cost effective. Unfortunately, they also come with a single disadvantage: they do not shed ice and water as quickly as an open valley would, which could cause your shingles to lose their granules faster and lead to the early deterioration of your roof.
