As of 2015, some gutter guards that are highly rated by experts are GutterDome, Gutterglove Pro and Gutterglove LeafBlaster, according to GutterProtectionReview.org. The site gives the guards five, four and 3.5 out of five stars, respectively.
Made from surgical-grade stainless steel and high-quality aluminium, GutterDome’s triple-patented micro-mesh design keeps out debris and is rust-resistant. The guard retains over 10 inches of metered rain per hour.
Gutterglove Pro’s anodized aluminium frame can be installed on a variety of gutter types and has an austenitic stainless steel mesh that filters debris. The guard can retain over 9.6 inches of metered rain per hour.
The LeafBlaster’s system consists of an extruded aluminium drip edge, a corrugated stainless steel V-Bend mesh filter that gives the gutter rigidity and a water siphon control strip.
