Mastic Leaf Relief
Homeowners choose Leaf Relief® for one simple reason — it works. (We wouldn’t have installed so much of it if it didn’t.) In fact, Leaf Relief has protected over 100 million feet of gutter over the last decade — longer than a gutter stretching from LA to NY and back three times, then continuing to San Francisco before heading back to LA. The patented design keeps debris out of gutters while allowing water to drain freely. All it takes is a normal breeze to lift debris away. Dry leaves require 6 mph winds, wet debris requires 23 mph winds.
