When it comes to roof quality, valley flashing is one of the secrets of a durable, long-lasting roofs, yet many homeowners do not even know what it is. When your roof has different parts that meet for various peaks and parts of the home, the joints are referred to as valleys. These concave areas attract moisture and are the most likely to be saturated during rain and snow.

Valley flashing is usually made from metal and is needed to secure the joints on your roof and protect them from leaks. Once the roofing material is put on, you cannot see the valley flashing, but it needs to be there performing its job. Unfortunately, if not installed correctly or if it becomes worn or corroded, it can lead to a major problem with your roof.

If installed correctly, your valley flashing should last with your roofing and protect your home from leaks. However, there are some poor flashing practices that can create issues with your roof valleys. These can include:
