I just had a roof replacement due to some hail damage earlier this year and the contractors have just finished installing the gutters. I'm a little concerned about how they installed them. The new roof came with a new drip edge that appears to have been installed correctly, but when they installed the gutters they ran the hangers right though the drip edge.
They also appear to have left a bunch of open screw holes. I called around and about half the gutter companies say this is how they do it and the other half say this shouldn't be done. Is this likely to cause issues in the future or am I just being paranoid?
