Thanks to advice here, I got up the courage to start cutting back the first row of shingles that blocked about half of the gutters.* Interesting - the previous shingling job that came with the house when we bought it 25 years ago was also about the same too long length (that job was a 2nd layer over a previous layer. I don't know what that first layer looked like.* maybe 3 different roof jobs with stupidly long shingles?* I've been cleaning gutters for decades with scratched up hands as I reach in to remove leaves (even 1/2 obstructed, leaves collected quite well!).* Seeing the whole gutter looks weird!

Anyway.... so I realized - cutting back that first row of shingles cuts off the sealing strip on the starter row. So that first layer can lift up.**

1) Would you do something to re-seal the starter row to the first layer?
2) What would you use?* *Something like this?*

Just squirt between the layers?* I am concerned if I use something too liquid will run a bit / drip into the gutters?

Depends on the pitch and normal wind conditions in your area.


But if I were to do it and I wanted to use something in gun I would use the cheaper product. https://www.homedepot.com/p/Roofers-Choice-11-oz-Plastic-Cement-Roof-Patch-RC015004/202091010


The stuff in the .9 gallon can is much cheaper than the tubes. It is much more messy to work with.


A couple of quarter sizes daubs under each tab is all you really need as the cement is much more effective than than the glue strip. Be sure to press the shingle down and only work on warm days.

ColbyT: Thanks! we're here in NJ. 'normal' pitch I can walk on pretty readily. Wind - we get hurricanes up here once in a while so potentially high winds.

I've learned to not economize all the time : ) I'd be covered with the stuff if I didn't have it in tubes.

Interesting - your material isn't available for delivery or in stores here in NJ.

Somewhere else, someone was saying that plastic products aren't as permanent as the asphalt based ones?

I was intrigued how strong the layers I cut off stuck together. no meaningful thickness to the sealing strip and it was no mess : ) Kinda envious everything can't be that good.

and a bunch of daubs not a line all the way across? even with the caulk, my habit is too much or too close to the edge so when the top shingle squishes it, it comes out the edge.

Learn to cut a smaller tip and don't pump quite so much on the handle. Also if your gun does not have a quick release, throw it away and buy on that does. The new gun will pay for itself by the time you run 20 tubes through it.

Thanks! The gun in my case isn't the issue. More the operator being heavy handed : )

So with Home depot not offering the caulk you mention... is there a close 2nd best or should I look around to find it? Again, you mention cheaper. I want to be sure to do it right (or at least use the right / best materials) and hope my install is worthy of the materials.

Any asphalt or plastic caulk is fine. It will last as long as your roof! I've used all kinds of stuff to do what you are doing, even regular caulk (which isn't ideal). I've even purchased a can of Gardners liquid asphalt and used a putty knife to dob it on and then lowered the shingle down into it.

Funny! I was at home depot last night looking at Karnak 19, 19 ultra, some things from Henry to do this. And saw gardner wet n dri (not with a plus though). I called / left a message for Gardner and 10 minute ago the guy called. I explained what I wanted to do and he said they had no adhesives for asphalt roofs? I mentioned this wet and dry and he said that stays soft for 15 years / doesn't fully cure / harden for that long. Didn't sound like what woudl work - peanut butter will hold 2 slices of bread together because it's gooey / tacky... but is that an adhesive?

I would love to get what they use in the sealing strips. That locked up the shingles tight and when I was working on a shed roof last summer, if I wasn't careful, the sealing strip on scraps were getting stuck to other things very quickly : )
