Valleys and ridges are components of your roofing system that are vulnerable to leaks. Here are some notes from our team at Tedrick’s Roofing to help you understand what makes them so and how to better care for them.
Where You Can Find Them
Ridges are formed at the highest point where roof slopes meet and where the edges are attached to either a beam or a board. A ridge cap is then installed to prevent water from getting in through the ridge itself.
Valleys are formed at the lowest point where roof slopes meet. There are two types of valleys: open and closed. Closed valleys are created by installing shingles across adjacent slope edges, creating a sense of continuity from one plane to another. Open valleys are created when, instead of shingles, flashing is installed to cover the valley itself. The flashing edges are then hidden underneath the shingles on each side.
Why They are Leak-Prone
Based on how ridges and valleys are formed, it is easy to see how they can be the source of a roof leak. At Tedrick’s Roofing, we look at several possibilities. A damaged ridge cap is one reason. Incorrectly installed ridge beams or boards also pose a risk. Broken shingles and inadequate flashing spell bad news for roof valleys, whether open or closed. Water collects in the valleys, and if it seeps underneath your first couple of roofing layers, water can damage your system.
How to Be Leak-Free
Prevention plays a huge role in preventing a leaky roof. Be sure to work only with true professionals in roof installation. Credible installers will know how much flashing to use and ensure that they are properly applied. Ask for high-quality shingles that can withstand severe weather, too.
