The AmeriMax 85198 and AmeriMax 854054 rate as excellent gutter guards, according to Consumer Reports. These self-installed systems are durable, effective and less expensive than many other options. Other highly rated gutter guards include the Gutterglove Pro, Waterloov, Raindrop and LeafFilter systems.
Gutter guards come in several styles. Metal and plastic mesh guards fit over the gutters and prevent debris from falling inside. Another type of gutter guard, the foam insert, sits inside the gutter channel. The foam allows water to pass through the gutter but filters out most seeds, insects and other small debris. Foam inserts work well but require treatment with a fire retardant. The best foam guards consist of insect-repellent materials.
