What is a Roof Valley?
There are certain parts of your roof that are more vulnerable than others. The roof valley can be one of these parts and might require the occasional roof repair.
A roof valley is the part of a roof where two slopes meet. Water collects in the valley and then drains from the roof. It’s essential that a roof valley is installed properly because they can be vulnerable to serious leaks if they’re not installed and maintained properly. When a problem occurs with a roof valley, it needs to be repaired straight away to prevent it from getting worse.
Types of Roof Valleys
A valley is formed where two roof slopes meet, forming an angle to allow water to drain. There are two main types of roof valleys, which are open and closed.
1. Open Roof Valleys
Open roof valleys don’t have any roofing material installed over them.
2. Closed Roof Valleys
Closed roof valleys, on the other hand, are enclosed by shingles installed over them.
Both types of roof valleys direct the flow of water away from the roof. Whether a roof valley is open or closed, it needs to be installed with the right materials. The required materials will depend on the type of roof valley.
Important Roof Valley Materials
A closed roof valley is often preferred due to its aesthetics. But it also needs some extra materials to help it function properly and protect it. Closed roof valleys require ice and water shields which protect the roof decking in the event of water getting underneath the shingles enclosing the valley.
An open valley requires metal flashing, which is usually steel. However, other metals are available. Some people prefer options such as copper, which can look better.
Whether an open or closed roof valley is installed, it’s essential that the installation is completed effectively. Poor installation could lead to problems later on. Roof valleys also need to be maintained to prevent any issues from developing.
Important Roof Valley Maintenance
Roof valleys shouldn’t have any major problems if they have been installed correctly, and using the right materials. However, it is also crucial to carry out routine maintenance to prevent problems. One of the major issues that can lead to the need for repairs is debris collecting in the roof valley. When debris, such as leaves, starts to build up, it creates a dam that prevents water from draining properly. This can cause water to back up on the roof and get under roofing materials, creating damage and leaks.
It’s important to carry out maintenance and clear away debris to protect roof valleys.
