Protect every roof valley with precision using the Amerimax 20 in. W x 50 ft. L Aluminum Roll Valley Flashing in Silver. This versatile, multi‑purpose flashing is engineered to seal joints, transitions, and penetrations with a single, continuous strip that adapts to complex roof lines.
Why this roll stands out:
-
Material and thickness: durable aluminum at 0.0092 inches thick offers a resilient combination of rigidity and pliability that holds its shape under wind-driven rain while remaining easy to bend along rakes, valleys, and contours.
-
Size for efficiency: 20 inches wide by 50 feet long provides ample coverage for long valley runs, reducing the number of seams and overlaps you have to manage.
-
Multi‑purpose design: built for multiple entry points and transitions, making it suitable for both shingle and metal roof configurations and various valley layouts.
-
Finish and compatibility: a silver finish that blends with most roofing materials and won’t corrode with exposure to the elements, extending the life of your flashings.
-
Convenient packaging: single roll per package, ready for immediate use on the job site or in DIY projects.
Ideal use scenarios:
- Valley flashing along long roof valleys where water runoff concentrates and leaks are most likely.
- Joints where roof planes meet, including transitions from hips to valleys or eaves to ridges.
- Around penetrations such as vents, pipes, and skylights where a seamless, weather-tight seal matters most.
- Repairs or upgrades to existing flashing systems that require a reliable, easy-to-form aluminum solution.
Practical installation notes:
- Unroll the flashing along the valley or joint, cut to length, and shape to fit the roof contours. The roll form makes it straightforward to bend around curves without kinking.
- Secure with corrosion‑resistant roofing nails or appropriate fasteners along the edges and at key points in the valley to maintain a tight seal.
- Overlap joints by a few inches and seal with compatible roofing sealant or adhesive where required to ensure a continuous barrier against moisture.
