When water overshoots your gutters at roof valleys, it doesn't just create a mess — it can lead to serious and expensive problems. Overflowing water can pool around your foundation, seep into your basement or crawl space, and cause a range of issues, including mold and mildew growth, structural damage, landscape erosion, and more.
SlowFlo is designed to solve these problems.
Engineered with 323 angled polypropylene channels and a unique curved edge, SlowFlo captures and slows fast-moving roof valley water before it can overshoot your gutters. That means no more splash guards, no more clogged corners, and no more water seeping into your basement.
Not every storm is a downpour — but when it is, let SlowFlo safeguard your customers and their property.
