A common problem for customers who have a Gutter Helmet installed is water pulling wet debris, such as leaves and twigs, around the curved nose and into the gutter where it accumulates. This collects with other debris until the gutter becomes blocked.
Another performance problem is that, if not properly cleaned, grime builds up on the outside causing water to not adhere to the surface and miss the gutter. Performing simple, periodic maintenance is required to keep this from occurring. A more aesthetic consideration about Gutter Helmet is its high profile design. The aluminum sheet metal is visible from the ground and is unappealing to some homeowners.
