What Is a Roof Valley and Why Do Valleys Leak?

A roof valley is the channel where two roof slopes meet. Because rain from both slopes funnels into it, a valley carries more water than any other part of the roof. Valleys leak when debris piles up, shingles or flashing wear out, or the valley was not installed correctly, which makes them a common leak source in Myrtle Beach.

Why Are Valleys Prone to Leaks?

Heavy water flow, collected leaves and pine needles, and wear from runoff all put extra stress on valleys. Any small gap gets tested every time it rains.

What Are Signs of a Valley Leak?

• Stains on ceilings below where two roof sections meet.
• Debris piled in the valley.
• Worn, cracked or lifting shingles along the valley.

How Are Valley Leaks Repaired?

A roofer clears debris and replaces worn shingles or flashing in the valley. Honest Roofers handles roof leak repairs and installs ice and water shield along the lower edge of every new roof. Read why ice and water shield matters.

When Should the Whole Roof Be Replaced?

If valleys and other areas are wearing out together, roof replacement in Myrtle Beach may be more cost-effective than repeated repairs. Also see how gutters affect your roof.
