Does Leaf Defier™ hold water like a sponge or restrict the water flow?
Definitely not. Unlike a sponge, Leaf Defier™ is made from hydrophobic polyurethane that actually repels water. That and the proprietary open-cell design provide an INSTANT flow-through rate of over 98%. This is the highest flow-through rate of ANY gutter protection product. From a practical standpoint, it’s as if Leaf Defier™ is not even there. Any remaining water continues to drip through the product and eventually drains or evaporates.
