The answer to 'how to maintain downspouts' is to regularly inspect and clean your downspouts to ensure they are functioning properly. Downspouts play a critical role in directing water away from your home's foundation, so it's important to keep them clear of debris and damage.
Start by visually inspecting your downspouts for any clogs, leaks, or loose connections. Use a garden hose to flush out any debris, and consider installing downspout extensions or splash blocks to direct water further away from your home. If you notice any significant damage, it's best to call a professional roofer or gutter specialist to make the necessary repairs.
