I noticed this clicking noise when the dryer was spinning before I open the dryer does anyone have an idea on what the potential problem could be?

I’m not too up to date on how gutters are installed. But I hired a professional company to instal them and this was a result. I called about the hole being to small and I was told it’s to have more pressure for the water to get out. But then I see the exposed nail. What do you guys think. Is this a good instal?
