Products / FlowGuard Slip Under Shingle Gutter Cover

A universal FlowGuard aluminum gutter cover for 5 and 6 inch gutters whose back edge slides beneath the first row of shingles instead of fastening to the fascia. The product page gives .018 inch aluminum with interlocking, cut-to-length pieces and supplied hardware, made in the USA. The maker's home page excludes this slip-under version from its statement that FlowGuard does not interfere with roof warranties, and backs FlowGuard products with a 50-year warranty against defects in materials and workmanship.
