Key Features

• Made in the USA: Every component is manufactured domestically, which supports consistent quality control and materials sourcing.
• High strength construction:.018 heavy gauge painted aluminum with full front and rear hem increases rigidity to resist heavy rainfall, snow loads, and strong winds.
• 3-point airflow design: Elevates wet debris so it dries and blows away over time, reducing clogs and sticking that cause overflow.
• Easy installation: Dual interlocking ends, 45 degree drain hole pattern, and included stainless steel 1/2 in #8 twin thread pierce point zip screws let a handy homeowner cut and fit the system with tin snips and a drill.
• Low maintenance: The cover prevents most leaves and debris from entering gutters, dramatically reducing or eliminating annual gutter cleaning.
• Long warranty: Backed by a 50 year manufacturer's warranty for long-term peace of mind.

Who It's For

The FlowGuard gutter cover is best for homeowners with standard 5 in gutters who want a durable, permanent cover that stands up to heavy weather and minimizes maintenance. It suits DIYers who can handle cutting aluminum with snips and securing the system from a ladder, and those who prefer a white finish to match white gutters and trim.

It is less suited to people who cannot safely use a ladder or who require a professional-installed system due to complex roof details; while the product is pitched as DIY-friendly, steep or intricate roofs may be better served by hiring a pro who can flash under shingles without voiding any roof-specific requirements.
