This is a common issue that can be caused by factors like heat, sun exposure, and moisture. Curling gutter guards can become less effective at keeping debris out of your gutters and may need to be replaced.
Symptoms of curling gutter guards include visible warping or bending of the material, gaps forming between the guards and the gutter, and increased debris accumulation in the gutters. Solutions can include adjusting or tightening the gutter guards, cleaning the gutters, or replacing the guards entirely if the curling is severe. For DIY homeowners, minor adjustments may be possible, but significant curling or damage to the gutter guards often requires professional repair or replacement.
