The gutters will not work properly if they are clogged. Some good signs the gutters are clogged is the water coming over the top, water in the basement, water constantly dripping of leaking from the gutters when it is not raining or hasn’t rained recently. Water leaking inside your home/building, generally where the ceilings meet the walls. These are just the most obvious signs of clogged gutters, sometimes the signs are not so easy to spot, which is why we recommend cleaning the gutters twice a year.
