Gutter-Fascia-Splash Guard

In the process of replacing gutters and in doing so I want to prep the fascia for the gutter reinstall. Not an authority, it does not appear the fascia needs to be replaced, I am sanding and considering applying a thin coat of a filler, perhaps a plastic type to coat the surface, sand, paint and install the gutter.

The flashing is set under the felt and shingles, I wonder if possible to add a splash guard above the felt and under the shingles to ensure the run-off hit the gutter by extending the drip-line and perhaps offer other options in my selection of gutters?

Appreciate comments/suggestions!

 

The only reason water would miss the gutter is if you install the gutter too low. The back of the gutter should be fully under the flashing and should not drop below it anywhere... not even at its lowest point (at your outlet/downspout).

And please don't use vinyl gutter.

 

Certain I overcompensated for the slope due to the amount of annual rainfall in my area and set the gutter below the flashing towards the drain pipe. I intend swapping to different type of hanger. I did use vinyl gutters once in the past and soon found it was a mistake and swapped to metal within a couple of years.

I found your comments very helpful and thank you!!.

 

They make both 5" and 6" k style gutter... larger gutters can obviously move more water. Also downspout sizes are either 2x3 or 3x4... 3x4's can move 2x the water. Seamless gutters run by a professional company are well worth the $$$. If you would like to install yourself, they are often happy to oblige.

Gutters don't need much slope to drain... water seeks it's own level. The main reason to have any slope is to ensure you don't have standing water ponding anywhere, and to help small debris find its way to the outlets. Of course, that only works if the gutters are kept pretty clean.
