FlowGuard 5 in High Clearance Gutter Cover System - White

In this review of the FlowGuard 5 in High Clearance gutter cover system, the bottom line is simple: this is for homeowners who want a long-term, low-maintenance solution for gutters that use high profile brackets or need heavy-duty protection. The reviewer found the USA made aluminum construction and the three-point design to be the single biggest reasons to buy, because they keep leaves and seeds off the surface while letting heavy rain pass through. Installation is straightforward for a DIYer and the included stainless steel fasteners make a secure, permanent fit.

Key Features

• Made in the USA: The cover is manufactured domestically, giving buyers confidence in consistent material and assembly quality.
• Heavy gauge aluminum:.018 painted aluminum resists rust and deterioration so the covers last through seasons of rain and snow.
• High clearance design: Specifically shaped to clear high profile gutter brackets for a proper fit on more systems.
• Three-point airflow: Elevates wet debris to prevent sticking and allows light wind to remove dried debris over time.
• Complete hardware kit: Includes stainless steel 1/2 in #8 twin thread pierce point zip screws so mounting is secure and corrosion resistant.
• 50 year warranty: A no questions asked warranty provides long-term peace of mind for homeowners.

Who It's For

This gutter cover is aimed at homeowners with k-style or similar gutters who want to stop frequent cleanouts and handle heavy rainfall without overflow. It is particularly useful where high profile brackets are present or where roof run-off brings heavy debris like maple samaras or wet leaves.

DIY installers with basic metal cutting tools will find this product fits well and is easy to trim and interlock; those looking for a decorative or seamless hidden system should look elsewhere, since FlowGuard mounts on top of the gutter and has a functional, utilitarian appearance.
