Valley Vigilance: Maintaining Roof Valleys for Longevity

Understanding Roof Valleys

The roof valley is the internal angle formed when two sloping roof planes meet. Think of it as the low point between two roof slopes, similar to a valley between hills. Proper construction includes flashing covering the valley's entire length to prevent water damage. This area is highly susceptible to water accumulation, making it one of the most vulnerable spots on your roof.

Types of Roof Valleys

• Closed Valleys: These have flashing covered with shingles. Closed valleys offer better protection by covering and overlapping the shingle edges, reducing the risk of water penetration, especially during heavy rain or snow thaw. This system, although slightly more expensive (around $150-$500 depending on the home and material), ensures better performance and durability.

• Open Valleys: Here, the flashing is exposed. Proponents argue that this method allows rainwater to move away from the roof faster due to less friction. It's also cheaper to install as it requires fewer materials. However, it leaves shingle edges exposed, increasing the risk of water damage.

Maintaining Roof Valleys

Given the high water flow through valleys, regular maintenance is crucial. Ensure the flashing is intact and free of debris. Inspect for any signs of wear or damage, and address issues promptly to avoid costly repairs.
