Gutter leaks usually start at joints where sections connect, or at corners where the gutter changes direction. Over time, the sealant deteriorates, metal expands and contracts, and joints work loose.The key to permanent repairs is addressing both the immediate leak and the underlying cause. Simply slapping more caulk over old, failed sealant won’t last. We remove the old material, properly clean the joint, and use professional-grade sealants designed for your specific gutter material.Sometimes leaks indicate that your gutters are undersized for your roof area or improperly pitched. In these cases, the repair might involve adjusting the slope or adding capacity to handle the water volume your roof generates.
