To adjust the slope of the gutter, wear gloves and pull out the pins on the side and around the corners. Loosen the drip edge with a screwdriver. Use a hammer and a lever to loosen the gutter. This can be the direct result of an incorrect fall, a common problem in gutters that occurs when the standard gutter gradient is too level for water to flow through.
A correct slope of the gutters prevents stagnant water caused by rain from accumulating in the roof gutters.
