In most cases, the combination of the roof shape and gutter guard slope will encourage leaves and debris to fall to the ground in wind and rain. When trees with heavy or finer debris overhang the gutter guard, homeowners may need to gently sweep or blow the debris off the roof. If your gutters have a correct fall, dirt and small particles will flush out with water flow; if this is not the case, you may need to wash the gutters.
Please note gutter mesh is slippery on any roof type, do not walk on the mesh to reduce the chance of damage and a fall.
