Thoughts on Tile Valleys
Updated: Jul 13, 2022
Closed Valleys are identified as any valley area where the shingle or tile are installed in a manner where the valley metal is hidden and installed without much of a gap. This gives a continuous appearance to the material on the roof and can be found on roofs and home designs that prioritize aesthetics over function.
Closed valleys require more attention from homeowners to prevent leaks from developing over time.
The Open Valley
An open valley has a more exposed valley metal. The roof material is cut in a manner where both sides of the area provide a larger channel for water to flow through.
The open valley may not look as seamless, but it functions as intended, directing water off your roof. It stays cleaner and preserves the underlayment over the years. I always recommend it, and you should request it when installing your roof.
