Yes, there are several downsides to installing rain chains. For one, rain chains have a lower flow capacity than a typical gutter and downspout system. This means that if there is a rainstorm, the rain chain can stop working completely. Rain chains also cannot redirect rainwater away from your house. In homes with a sloped yard, this could cause water damage in your foundation or basement. 

Although having gutter guards and hoods dramatically reduces the number of times you will have to clean out your gutters, it doesn't necessarily mean that you won't ever have to clean your gutters. Experts recommend cleaning your gutters at least once every two years, even with gutter guards and hoods installed. If you don’t want to clean them yourself, you can hire a gutter cleaning company near you to complete the job.

Failing to clean your gutters can lead to serious and costly damage. When leaves and other debris cause blockages, water cannot drain properly and will overflow. This can lead to water pooling around your home’s foundation, causing basement flooding and structural damage. The overflow can also damage your roof, siding, and fascia boards, with the constant moisture promoting mold, mildew, and rot. The weight of wet debris can cause gutters to sag or break, while stagnant water creates a breeding ground for pests like mosquitoes and rodents. Additionally, runoff can damage landscaping or freeze on driveways and patios, causing cracks. To prevent these issues, it is recommended to clean your gutters at least once or twice a year.

You may have a clogged gutter. Downspouts can also clog if your gutter collects too much debris. Hire a professional gutter cleaner, and if you still have problems, install a gutter guard (which prevents debris from entering your gutter system) and a downspout extension (which helps drain water further away from your foundation, so it doesn't pool near your house). Follow these tips to keep your gutter downspouts clean.
