FlowGuard 5 in High Clearance Gutter Cover System - Durable, DIY

Our review of the FlowGuard 5 in High Clearance gutter cover finds it best for homeowners who want a long-lasting, low-maintenance solution for leafy or heavy-rain climates. The single biggest reason to buy is the combination of heavy gauge aluminum construction and a 3-point elevated design that keeps wet debris off the surface while allowing heavy rain to flow freely into gutters, which substantially reduces the need for seasonal cleaning.

Key Features

• Made in the USA: The cover is manufactured domestically, offering consistent build quality and a reassuring 50 year manufacturer warranty.
• Heavy gauge aluminum:.018 painted aluminum resists rust and deterioration so the covers stay serviceable through severe weather and years of exposure.
• High clearance design: Specifically shaped to clear high profile gutter brackets so it fits over larger hanger systems without interference.
• 3-point airflow design: Elevates wet leaves and debris to prevent sticking and allows light winds to blow dry debris away over time.
• Included stainless screws: Comes with 1/2 in #8 twin thread pierce point zip screws for secure, corrosion-resistant mounting.
• Easy to trim and install: Dual interlocking ends and a 45 degree drain hole pattern make cutting miters and continuous runs straightforward for DIY installers.

Who It's For

FlowGuard High Clearance is ideal for homeowners with k-style or PVC gutters who need a robust, long-term gutter guard that handles heavy rainfall, snow loads, and areas with lots of leaves or seed pods. It suits DIYers comfortable cutting metal with tin snips and fastening with a drill, and those who value provided stainless hardware and a product that mounts on top of the gutter.

Those who should look elsewhere include people seeking a temporary or ultra-low cost solution for very shallow gutters, or homeowners who cannot use top-mounted systems due to unique roof or soffit constraints; also, if you need a hidden under-shingle system, a different style may be required.
