The amount of the roof rain gutter downspout maintenance depends mostly on the rain gutter maintenance and the downspout bottom end / its extension condition.
There’s not much to worry about if you’re living in a tree-free neighborhood, where your rain gutter downspout will (in most cases) require no maintenance.
However, every tree located close to your house will increase the chances of losing some of your valuable time on rain gutter downspout maintenance. The closer and taller the trees are, the more maintenance might be required.
The simplest method to minimize it and keep the gutter downspout interior clean is to install the rain gutter strainer. The gutter strainer will stop leafs and other debris from flowing into the downspout, and in some cases, contaminating it.
You have to remember to clean the gutter strainer periodically (depending on the number of trees surrounding your house) to prevent it from blocking the water flow.
Your rain gutter downspout should do OK without the gutter strainer if there are no trees in your area.

1. Observe your rain gutter downspout discharge while it’s raining.
If there’s little or no water coming out the downspout bottom end – check the gutter outlet first (top of the downspout / at the rain gutter attachment point). If it’s contaminated – clean it and watch if that improves the water flow.
