This is the house I live in on my family farm and I’m trying to add gutter hangers because I’m tired of the gutters sagging when we get our 10” of rain a year. Here’s a picture of the problem, they have hangers every 6-8’ and I was thinking of putting one every 2x4 or at least every other. The 5” hangers that are in stock at stores near me are way too long. Do they make 3”-4”? I can’t find them anywhere, there’s no fascia board sadly just the end of the 2x4s for the roof to screw into. Can someone help me get the right hangers? I attached the style that I’d like to get but they’re too long

Edit: from what I can tell the little lip on the gutter should be sitting on the roof decking and it’s pulled out from under the shingles due to the sagging. There’s about 300’ of gutter like this with another 100’ that a worker “fixed” by putting self tappers through the back of the gutter into the 2x4s sticking out of the roof.…
