The answer to 'why is my gutters algae growth' is that algae growth in gutters is a common problem caused by moisture, debris, and lack of cleaning. Algae thrive in the damp, shaded environment of clogged gutters, which can lead to blockages and water overflow issues.
Some common symptoms of algae growth in gutters include a green or black slimy buildup, foul odors, and water backing up or spilling over the sides. To address this, it's important to regularly clean and maintain your gutters to remove debris and prevent algae from taking hold.
