FlowGuard High Clearance 5 in Gutter Cover System - 125 ft

In this review of the FlowGuard USA Made Professional DIY 5 in High Clearance gutter cover system, the bottom line is simple: this is a durable, DIY-friendly solution for homeowners who want to stop leaves and debris from clogging gutters while preserving strong performance in heavy rain and snow. The reviewer found the product especially useful where high profile gutter brackets are present, since the design clears brackets and mounts on top of existing gutters. For anyone tired of annual gutter cleaning, FlowGuard's heavy gauge painted aluminum construction and included stainless steel screws make it a straightforward, long-term option.

Key Features

• Made in the USA: Manufactured domestically for consistent quality control and materials traceability.
• High strength material:.018 heavy gauge painted aluminum resists rust and holds up under snow and wind for long life.
• High clearance design: Specifically shaped to clear high profile gutter brackets so it fits where other covers might not.
• 3-point design: Elevates wet debris to allow airflow and prevents leaves from sticking, helping dried debris blow away in wind.
• Complete fastener kit: Includes stainless steel 1/2 in #8 twin thread pierce point zip screws so installers have the proper hardware on hand.
• Dual interlocking ends: Makes continuous runs and mitered corners easier to cut and assemble during installation.

Who It's For

This product suits homeowners with k-style or similar gutters who want a permanent, low-maintenance solution and have some DIY skills or a contractor to assist. It is a good match for properties in regions with heavy rainfall, seasonal leaves, or snow load concerns because the reinforced hem and heavy gauge aluminum stand up to stress.

It is less appropriate for those who need a temporary or non-permanent cover, or who prefer a snap-in system that hides fasteners beneath shingles; FlowGuard mounts on top of the gutter and uses visible stainless fasteners for a permanent install.

Pros & Cons

Cons

• Permanent top-mounted installation means visible fasteners and a non-removable cover, which some homeowners may not prefer.
• Cutting and fitting mitered corners requires tin snips or metal shears and some time for accurate work.
