The hangers are the accessories that secure the gutter to the building's fascia plate. If the gutter is not angled properly, adjust the hangers to achieve the proper slope. This can be done by loosening the screws that hold the hanger to the fascia plate and repositioning the hanger so that the spout is properly angled. Tighten the screws to fix the hanger instead.
Repeat this process along the entire length of the gutter, adjusting the hangers as needed to achieve the proper slope. Once you're done tilting again, clean the gutters to remove any debris or blockages. Loosen the screws on the gutter hooks and adjust them to achieve the desired inclination. Make sure to tighten the screws well to maintain the new position.
Reevaluate the playing field using the level.
