One of the purposes of these blocks may be to extend the mounting point of the gutter. Notice how the channel is attached to these blocks and where the lower edge of the fascia is in relation to the channel. It is possible that the original installer wanted to install the gutter at the bottom (current position), but it didn't have enough fascia on the bottom edge to provide a solid mounting point. I would have to look behind the gutter and see if those mounting blocks extend beyond the edge of the fascia.
If miscalculated, gutters can be ineffective and cause significant damage to the roof and walls of your home. The architecture of your home and the local climate also play an important role in determining the correct size and position of the gutters. This contributes to rust, erosion, mosquitoes and damage to the gutter support system caused by constant excess weight. To clarify, as I understand the result of this discussion, the lower part of the dripping edge should not even touch the fascia, while the channel should be flush of the fascia.

To use and fire it, you must ensure that the screw goes through the back wall of the gutter. However, there is science that says how far they should be inclined, and making a mistake can cause rain gutters to overflow. A gutter that is too steep and has too many joints is an additional problem affecting many gutter installations that you can do yourself (do it yourself). What many homeowners don't know is that if a gutter of the wrong size is installed, it can cause significant damage to the foundation and the walls.
If the gutters are not attached to the edge, the water will not be properly redirected to the downspouts. I used it about a kilometer and a half ago just 2 weeks ago in a house I was repairing (I had put a new roof and gutters on it last year). Gutter hangers should be placed every three feet for proper support, and even closer if you live in a cold climate with lots of ice and snow.
