The Difference Between an Open and Closed Roof Valley
You may have heard the term "roof valley" used by a Lexington Roofing pro in regards to your roof but you may not have had the foggiest about what they were talking about. The valley of a roof is where two connecting slopes assemble to form a V-shaped angle. Today, we will be talking about open and closed valleys on a roof.
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 noticeable. When an open valley is accurately fitted it should last for a considerable 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.
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 an open roof valley is more cost-efficient, it is also not as efficient as an open valley will be at shedding 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.
