Standing water in a metal gutter accelerates corrosion of the substrate, ultimately resulting in failure if the gutter is not adequately protected with a high performance waterproofing system. However, if corrosion is arrested with Rooflock Twelve Gutter System before any structural damage occurs, the long term performance of the gutter can be safeguarded without prior need for replacement. We recommend that all gutters are regularly maintained and cleaned to ensure free flow of water to the drains. Standing water promotes the growth of organic matter, which can clog the gutter and cause leaks if the water backs up into the building
