Sounds like the downspouts are clogged?

The typical thin aluminum is easily damaged with a plumbing type drain auger.

A garden hose will often work well enough to clear them.

You may have to work from the top or the bottom depending on how clogged they are.

Careful use of a hand powered drain auger can help, but it tends to just drill a small hole through the clog without really removing it.

You may even need to alternate the hand auger and the hose, or actually take the downspouts apart to clear them.

Thanks for the idea. I bought one of those Ridgid augers that you attach a hand drill to. It worked pretty well, didn't go through the alluminum best I can tell and I think the drains are open now. I need to run water /pressure washer through them to make sure. The runs are pretty long.

Thanks for the help!
