The answer to 'gutter cleaning sagging' is that sagging gutters are often caused by a buildup of debris, improper installation, or structural issues. Symptoms include water spilling over the sides, gutters pulling away from the roof, or standing water. Solutions can include clearing debris, tightening gutter hangers, or in severe cases, replacing the entire gutter system.
For minor sagging, homeowners can often address this themselves by cleaning out the gutters and securing any loose hangers. However, for more extensive damage or if you're unsure of the cause, it's best to call a professional roofing contractor to inspect and repair the issue properly.
