As part of a roof replacement I also had the gutters replaced, and I was surprised today when I saw how they attached the downspouts.
There appear to be one sheet metal screws protruding downward through the bottom of the gutter on either side of every downspout. The sheet metal screw protrudes through the bottom of the gutter 3-4 threads. The head of this sheet metal screw is covered with a calking material within the gutter, apparently to prevent leaking through the hole it creates.
My original gutters did not have these screws, nor do my neighbors. This not only looks a little goofy, it seems like a bad idea to screw holes into the bottom of gutters. Before I ask them to replace all the gutters, I'm looking for some perspective. Is there any way this could be right?
