The answer to 'my gutter cleaning is failing' is that there could be several common causes, such as clogged downspouts, damaged or sagging gutters, or a buildup of debris. Symptoms may include water overflow, standing water, or gutters pulling away from the roof. Solutions can range from simple DIY cleaning to more complex gutter repairs or replacement.
If the problem is minor, such as a clogged downspout, you may be able to resolve it yourself by flushing the downspout with a garden hose or using a gutter cleaning tool. However, for more significant issues like sagging or damaged gutters, it's best to call in a professional roofing technician to properly assess and fix the problem.
