UPDATE round 2:
So they fixed all the items I found in the first post. But we had very little rain for several weeks so never a chance to see these gutters work much.
Well I found a leaking/overflowing section of gutter on the back corner of the house, I go up to make sure pine needles haven't clogged it up and it becomes apparent that this shorter section is sloped down ~ 2" away from the single downspout over a 10 ft run- theres 2" of standing watwer at the endcap while the downspout outlet is high & dry.
Not only that, but I look at the downspout and see this meatgrinder awaiting any gutter cleaner; look around and every downspout looks like this.
I asked the GC 'do you think this is a textbook installation?' and he acknowledges that it's just how this guy has always done them and is its leaking he thinks it would need to be made right, and to his credit it doesn't leak but i'm certainly not impressed. and its absolutely a flow restriction.
So again, would it be unreasonable to insist that they install proper flange collars? I've cleaned gutters on dozens of houses and never seen anything used but these;
quigleysiding do you have any input here.
What's really odd is when the gutter guy was out here fixing the items in post #1, I saw this punch tool laid out near the added downspouts, but i guess they must not have had the correct size/color of flange ️
