When installing a new roof, one of the decisions you have to make as a home or building owner is whether or not you want to have open or closed valleys. You are probably wondering what the heck that means. To make it easier on you, we have included some photos of open and closed valleys in this post, so that you can see the difference.
The first two photos are examples of open valleys. You can see the copper metal in the valley is exposed. Of course, as the copper is exposed to oxygen, it will develop a greenish tone called patina- but these photos were taken recently after the roofs were installed, so they are perfect for showing what an open valley is. You can tell that with an open valley there is a visible strip of metal that is exposed.
A closed valley is where the field tile shingles butt up to one another, so that strip of metal is not exposed. While there are some roof coverings that don't require metal flashing for closed valleys, our lightweight roofing materials require a self adhered membrane as underlayment, and copper, aluminum, or painted metal for open or closed valleys.
No matter which valley you decide to go with you can always refer to our installation guides on our website for directions.
