Rainwater from your roof drains through the 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. Testing shows Shur Flo’s filtration system keeps working even when covered by wet leaves or debris.
Shur Flo is installed to fit snugly to the top of your gutters and can be installed on existing gutters or a new gutter system. This system is available to fit both the 5” and the 6” size gutters without interference to the shingles and is perfect for a metal or rubber roof. 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.
