You’re due for a roof replacement and you’ve already contacted your local roofing company for the job. Now comes the first step in any home improvement project: planning. During the planning phase, the choice between open and closed valley roofing might come up when you’re replacing your roof. It can be a daunting decision, especially if you have no clue about what either one means.
Both roofing styles have their own set of advantages and disadvantages. Understanding their differences can help you make a better choice. Let our roofing experts at The Thomas Roofing Company, Inc. give you a closer look at open and closed valleys, as well as their many ups and downs.
Closed Valley Roofs
Valleys are the areas where two roofing panels meet each other. In a typical roof installation, once the underlayment and ice and water shields are laid down, the roofer will then have a choice in either placing the shingles to cover the valley. If they do, then the roof will have a closed valley in that the shingles have “closed” up the valley of your roof.
Open Valley Roofs
In an open valley roof, flashing is used to cover up the valley so the shingles may or may not extend over the valley area. The shingles are deliberately cut down to allow the flashing to be installed, which provides the roof with an effective way to control water flow.
Why Choose One?
If your roofing contractor installs a closed valley, the roof looks more finished and seamless. But the shingles that cover the valley themselves can be prone to water exposure. On the other hand, open valleys address the water issue and, while the flashing might clash with the rest of the style of your roof, it can be a good way to control rainwater flow.
