FlowGuard 5 in Gutter Cover System - USA Made Matte - 102 ft

In this review of the FlowGuard 5 in Gutter Cover System, the bottom line is simple: this is a professional-grade, DIY solution for homeowners who want long-term clog prevention with minimal maintenance. Manufactured entirely in the USA from heavy gauge.018 painted aluminum, FlowGuard is designed to withstand heavy rain, snow loads and wind while keeping leaves and debris out of gutters. The system is best for owners of standard 5 in gutters who value durability, a solid warranty and a product that installs with common tools.

Key Features

• Made in USA: Every component is manufactured in the United States, which supports consistent quality control and materials sourced for longevity.
• Heavy gauge aluminum:.018 painted aluminum with full front and rear hems doubles strength where fastened, resisting rust and deformation in severe weather.
• 3-point design: Elevates wet debris to keep it from sticking while allowing heavy rain to pass through, so gutters can drain even when partially covered.
• Easy DIY install: Dual interlocking ends and supplied stainless steel pierce-point screws make continuous runs and mitered corners straightforward with tin snips and a drill.
• Stainless fasteners: Includes 1/2 in #8 twin thread pierce point zip screws that resist corrosion and secure the cover long term.
• Long warranty: A 50 year no-questions-asked warranty gives peace of mind for decades of maintenance reduction.

Who It's For

FlowGuard is ideal for homeowners with 5 in gutters who want a professional, long-lasting cover without hiring contractors. It suits properties exposed to heavy rainfall, seasonal leaf drop, or occasional snow where a stout aluminum cover and secure stainless fasteners will reduce or eliminate regular gutter cleaning.

It is less suitable for nonstandard gutter sizes or for buyers who need a temporary, inexpensive stopgap; this system is built for permanence and performs best when permanently mounted to the top of conventional gutters.
