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. 

Pressure washing isn’t the only way to clean your gutters. Use a hose and a long-handled brush if you aren’t afraid of a little elbow grease. Alternatively, set up a stable ladder and scrub by hand with a brush. It’s also possible to purchase gutter wand extensions for hoses or a gutter vacuum if you don’t mind the investment. These help clean thoroughly without you having to scale a ladder.

Yes, gutters can still get clogged even with gutter guards installed. While guards significantly reduce the amount of debris that enters your gutters, they are not 100% effective.

Small debris such as pine needles, seedlings, algae, small leaves, and pebbles can pass through the guard's screen or mesh and accumulate over time. Clogs can also form if the guards themselves are not cleaned and become overwhelmed with debris on top, preventing water from entering the gutter.

If this buildup is neglected, it can lead to clogs, water leaks, mold growth, and even plants sprouting from the gutters. The primary benefit of gutter guards is not the complete elimination of maintenance, but a dramatic reduction in how often you need to perform it, often from several times a year to just once a year or less.

Gutters overflow in heavy rain for several reasons. The main reasons why your gutters could be overflowing in heavy rain include:

• Not enough downspouts to effectively remove water from your gutters

• Too small of a gutter width—the average gutter size is four to six inches

• Clogged gutters

• Incorrect slope

If you believe your gutters were installed incorrectly, it’s a good idea to know who to call for gutter leaks. Speak with a local gutter specialist to get to the bottom of your gutter system to stop water from flooding your property or yard ASAP.
