Flanders Roofing; Open And Closed Roof Valleys

We find that most homeowners are often only interested in the color and type of roofing material they want on their roof, which is very important, but many don't know the difference is between an open and a closed valley. If you don't know what a roof valley is, it is the area of a roof where two connecting slopes meet and form a V-shaped angle. Speaking of roofing, when was the last time you has your roof inspected by a local Flanders roof repair service? If you are not sure, call RBM Roofing today to schedule yours for free! In today's blog, we are going to briefly discuss the differences between the two, because knowledge is power.

Open Valley

An open valley is when a Lexington Roofing contractor attaches a sheet of metal to the deck of the roof and then cuts and lays shingles to overlap leaving the metal seam visible. When an open valley is accurately fitted it should last for a considerable amount of time. A lot of Lexington roof repair techs prefer an open valley because they discard ice and water promptly with their smooth metal surface. In the event that your roof is leaking at the valley, an open valley is much easier to access and repair than a closed valley. To make it more aesthetically pleasing to the eye, the metal is usually painted to enhance the color of the roof shingles.

Closed Valley

The other common type of valley on a house is a closed valley. This type of valley is also a popular choice for a Lexington Roofer because it is an easier installation process and they are more aesthetically pleasing to a lot of homeowners. Even though a closed roof valley is more cost-efficient, it is also not as effective as an open valley is at eliminating ice and water. The result of this slowly channeled water can cause excessive wear making it most likely the first area of your roof to start failing.
