Masterful Instructions
Begin by positioning a stable extension ladder at the downspout end of the gutter run and visually inspecting the slope or pitch of the horizontal trough as it travels toward the outlet. Use a 4-foot carpenter's level or a string line held taut against the fascia to verify a consistent downward gradient of at least 1/16 to 1/8 inch per foot of run toward the downspout. Walk the length of the gutter to identify low spots or sagging sections where standing water and heavy silt have accumulated, as these areas indicate a failure of the mechanical fasteners. Examine each hidden hanger, spike and ferrule, or bracket to ensure it is driven firmly into the rafter tails rather than just the thin fascia board; if a fastener has backed out, it creates a gap that allows water to wick behind the gutter and rot the wood sub-structure. Check the end caps and miters for structural separation and apply a bead of high-grade gutter sealant to any leaking seams after thoroughly cleaning the aluminum with a wire brush. Physically grasp the gutter at several points and apply a firm, downward pressure to test for play or movement; the system should feel rigid and capable of supporting the weight of a ladder or heavy slush. Ensure that the drip edge flashing from the roof extends over the back of the gutter to prevent back-splash erosion, and conclude by tightening any loose downspout straps or cleats that secure the vertical assembly to the building’s siding.
Look for tiger striping—black vertical streaks on the front face of the gutter; this is a sign that water is consistently overtopping the rim due to a lack of pitch or a clog, and the resulting electrostatic bonding of pollutants will permanently stain your gutters if the pitch isn't corrected immediately.
