Yes and no. Many experts believe reverse curve gutter guards are outdated, favoring alternative solutions like screens or micro-mesh. Many companies like LeafGuard claim reverse curve systems are self-cleaning. However, many homeowners note that the top of their gutter protection system remains clean because of regular downpours, but the inner lip of the curve requires regular cleaning and debris removal thanks to buildup caused by oils and dirt from shingles and other roofing materials traveling around the system.
