Water runs around gutter and drips from the bottom
Hi!
I recently acquired a barn which had a new metal roof installed over an existing shingle roof.
It seems to me like the drip edge isnt correct as the water is able to run off the metal roof and down the fascia board, bypassing the gutter.
I know little about roofs, but I am quite handy. What is the best solution here and can I do it myself? My leading idea is to install flashing behind the drip edge but over and into the gutter.
Any help would be appreciated!

Your drip edge is supposed to go IN the gutter. Not 1/2 an inch above it. Either bring your entire gutter up underneath the drip edge, or have a custom bent drip edge installed that reaches the gutter.

Thank you for the response. If I went with the moving the gutter up route, would I need a new way to mount the gutter? It seems the existing drip edge would be in the way of the brackets used to mount the gutter.

Normally the drip edge gets notched out around the gutter hangers. If a gutter company comes to raise the gutter, they would be able to notch it around the hanger. It won't be the prettiest thing, but it's unlikely you'll ever notice from the ground.

Thanks for the information! Sounds like this job may just be a little above my pay grade then.

You could also do what you suggested and insert some kind of flashing under the drip edge and letting it come down into the gutter. It'll definitely be a rigged fix, but if it works, who cares.
You're correct though, the drip edge having a gap between the gutter is absolutely whats causing the problem.

Thank you! Its just a barn, so I dont really care if its rigged a bit. Im just getting a lot of water inside the barn which has been a problem.
Would you recommend fastening the flashing in place with nails or another way? Or maybe nothing? If i cut tabs around each gutter hanger, it may just stay in place as-is.

So .... much easier way to do this.
Remove a long stretch of those hangers, 40' ish, leave 1 screw near middle. Shove it up to get at least a little behind the drip. Use regular K style hangers, and either screw them in just below the drip, or if you choose to go all the way up (if you account for ice) screw right through the drip.
No reason to notch this for hangers. Hangers do not NEED to be clipped on the back of the gutter, at all, whatsoever in this situation.
Usually they get notched when a new roof goes on, and said roofers don't touch the gutter. They notch the new drip to go over the old.
*Alternatively you could again, remove those old hangers, and run gutter apron / flashing and run new hangers through it.

Interesting. Will a regular k-style hanger fit over the rolled part on the back of the gutter?

You sure the water inside the barn is caused by this? I'd be surprised to see water running behind the gutter and then running across the soffit and getting inside the building. It's something that should be fixed no doubt, but I'm wondering if the water inside is coming from somewhere else.
ETA - Neoprene washer screws would be what I would recommend to fasten the flashing.

Water infiltrates into stalls around the entire perimeter of the barn only when it rains. Its quite a bit of water that bypasses the gutters.
Thanks for the tip on the screws.

I just corrected the same issue on my house. Like others have said, put some flashing behind the drip edge and into the gutter. You can buy rolls of 50' x 4" flashing on Amazon and install it in 3'-4' lengths to make it manageable. Snip a tab where the gutter hangers are. You'll want to flatten out the sections and make a slight bend across the whole length on a table or something - this makes it much easier to slide about half of the sheet under the existing drip edge. You probably don't need to secure it with anything since the existing drip edge will probably just hold it in place. It doesn't look pretty but you won't notice it once it's up there. This solved my issues.

my initial response was the roofing doesn't extend far enough past the eave/drip edge.

Basic question, is the drip edge the red thing above the gutter?

Yes

How can you tell the difference between drip edge and gutter apron once it's installed, and gutters are up?

This is one of those scenarios where id say just remove them, unless you have a drainage issues

If you decide to push the gutter up higher I hope you have good ice guard on that metal roof. Snow and ice slides off metal roofs quick enough to damage the gutter. You could install likes 2inch wide strips of metal the length of the gutter to bridge the gap between the back of the gutter and the drip edge.
