The Amerimax 66310 Roll Valley Flashing is a high-quality, multi-purpose aluminum flashing designed to provide superior protection against water infiltration in roofing and exterior applications. With its 10-inch width and 10-foot length, this roll is ideal for both residential and commercial projects where precision, durability, and flexibility are essential.

Key Features:

• Reliable Water Barrier:
  Specifically engineered for use in roof valleys—where two opposing slopes meet—this flashing acts as a critical moisture barrier, channeling water away from vulnerable seams and preventing leaks and structural damage 

• Multi-Functional Use:
  Beyond roof valleys, this flashing is perfect for base flashing, counter flashing, deck flashing, hip flashing, and trim around windows, doors, skylights, and dormers. It’s also a favorite for DIYers and hobbyists due to its versatility 

• Durable Aluminum Construction:
  Made from .0078-inch thick mill-finish aluminum, this flashing is lightweight, corrosion-resistant, and built to withstand the elements. It offers long-term durability in all climates without rusting or warping 

• Flexible and Easy to Work With:
  The smooth aluminum surface is easy to cut, bend, and shape, making it ideal for custom installations and tight spaces. It conforms easily to roof contours and complex angles without cracking or splitting 

• Convenient Roll Format:
  Supplied in a 10-foot roll, it’s easy to transport, store, and handle on the job site. The roll uncoils smoothly and lays flat for fast, efficient installation.
