|How Shur Flo Works Rainwater from your roof drains through our patented perf-flow filtration system. Leaves, pine needles, twigs and even the smallest debris are suspended on top of the panel. Air circulation from above and below allows the leaves and debris to dry up and blow away in the wind.
Shur Flo Gutter Protection is installed to fit snugly to the top of your gutters. The low profile makes it virtually invisible from the ground.
With Shur Flo, there is no lifting or penetration of your roof shingles. Shur Flo will not void any roof warranties.
