How to Seal Leaky Gutter Seams

How to easily and permanently “fix” a leaky gutter with an ingenious waterproof tape.

When I was painting the garage door, I noticed that water was dripping down on my head as I painted on the left side of the door.

When I looked up to investigate, I saw a dent and small crack in the gutter system that was installed along the roof line of the house.

Crack in a homes gutter

Since the rain gutters were replaced when we moved into the house, I knew the new dent and crack just couldn’t reappear like a fantom stain on a carpet that keeps reappearing even after you removed it.

I realized that a delivery truck driver must have hit the gutter and didn’t realize it. To maintain the gutters as well as stop rust and corrosion, I needed to fix the leak before it got worse.

What Is the Best Product to Use to Seal Gutter Seams?

Gorilla Glue Waterproof Patch and Seal Tape

The fast and permanent way to seal and fix gutter leaks or a leaky gutter seam is using Gorilla Waterproof Patch and Seal Tape. No messy sealant products or silicone caulk is necessary.

The flexible waterproof tape works on aluminum gutters as well as vinyl gutter. It instantly seals out water, air, and moisture. With an extra thick adhesive layer and UV resistant backing this tape conforms to form a permanent bond indoors and out.

The tape is 4″ wide x 10′ long and can patch holes, cracks, gaps and tears, even underwater. One roll costs about $13 so the gutter repair for sealing seams is not an expensive home improvement project.

It is also much easier to use than gooey and messy caulking sealants that come in a tube and need to be squeezed out.

Besides fixing a gutter, Gorilla Glue Patch and Seal Tape is also good to fix leaking water problems and seal items around your home, in your car, boat or RV, plus almost anything outdoors.

Helpful Tips

Before Applying the Patch & Seal Tape to Fix a Leaky Gutter 

  • Use a wire brush to clear away clogs and make sure the inside of the gutter where the seam, crack or joint is that needs repair, is clean of all dirt and debris. Doing this will help you to find out of the leak is being caused by a clog that is overflowing over and out of the gutter or an actual hole or crack in the gutter.
  • If the gutter is very clogged use a garden hose to spray the debris out of the gutter.
  • Prop your ladder securely against your house so that you can reach inside your gutter. The tape could be attached to the outside of the gutter, but since it is waterproof, I chose to attach it inside the gutter where it would be hidden.
  • For ladder safety: Consider having a helper keep your ladder in place while you are on it.
  • Remove any debris such as pine needles, twigs and/or leaves in the gutter and around the roof line. Make sure the area inside the gutter where the leak is coming from is clean and dry.

    Great story. What a nightmare your driveway must be for delivery truck. I just have a spelling comment, however. A few paragraphs in you say:
    “Since the gutter was replaced, I knew the new dent and crack just couldn’t reappear like a fantom stain on a carpet that keeps reappearing even after you removed it.”
    I think what you meant was the dent, “couldn’t reappear like a phantom stain.”
    Not a biggie but the old journalist in me couldn’t let it pass.

    1. Diane Henkler says:

      Hi John – Thanks for telling me about my mistake. :). I will fix.

  2. Madison McEwen says:

    Nice Article…Very interesting to read this article. I have learned some new information. Thanks for sharing.

  3. Sally J. Miles says:

    I used Gorilla Waterproof Patch & Seal Tape on the bottom of my solar birdbath. Sad to say it did NOT work. It continues to leak nonstop.
    I have photos and video if you would like to see what I’m talking about.

    1. Diane Henkler says:

      Hi Sally – I am not sure why it is not working. Is the birdbath metal or concrete? Concrete is a surface that is hard to attach things. I believe you as it may not work on everything. I have used the tape in two places so far – the gutter I wrote about and earlier this summer we used it to close up a rip in the canvas cover on our boat. It has stayed closed although the hot southern sun soften the adhesive. It spread out around the tape, but the rip has stayed closed.

      Have you reached out to Gorilla Glue? They may be able to help you figure out how to make the tape work for your birdbath. Here is there customer service form:

    Does what it claims to do.

  11. SERIOUSLY???
    Oh My GOSH! Our RV has a little leak on one of the slide outs, and this would be perfect. But even better than that, we have an expensive air mattress in the RV that developed a leak, and we can’t use it but I still have it. We have tried to “fix it” with tape, but it doesn’t hold. I’m going to try this. I love Gorilla products anyway, and we just recently used another one of the tapes to adhere some 1/2″ x 4′ x 8′ pink, insulated foam board around the lower edge of our 5th Wheel RV to close off the underside. That tape is amazing!

  26. Elaine Williams says:

    I had an oval mirror and a collection of really cool shells. My neighbor who is more artistic than me hot glued the shells on in a spray manner that looked fabulous. I know me I would have done it very very symmetrically which is why I got him to do. Long story short the shells began dropping off. The cure for that? Clear Gorilla glue. Dries clear. Perfect!

  42. Michelle S. says:

    I can think of a lot of uses around my house for that tape. It should be in any man’s toolbox right along side the hammer and duct tape….LoL

  50. Great to know there is a cost effective way to deal with this common issues!

  51. Very good to know! Will definitely be going to Home Depot to purchase this product. We have a little Jon boat that keeps leaking and cannot seem to get repaired. Anxious to try the Gorilla tape for this fix.

  52. Bonnie Roelofs says:

  53. Wasn’t aware of this product – will have to purchase some to have on hand! Thanks for info.

  54. Sounds like a perfect product to have at the cottage (built in the 1930’s) ……there’s always something that needs attention. Thanks for the information.

  55. Hi, Diane!
    Do you think it would work on my cracked rainboots? Every pair of rainboots I get seems to develop cracks after about a year of use. They are not on the top of the foot area, but right on the sides where puddles can really get my feet wet. (I’m thinking mfgs are using more plastic than rubber in boots these days). My hubby thinks it’s the way I walk, but I don’t think so.
    Thanks for the tip,

  56. May try this on small pipe leak

  57. This sounds like a life-saver. Thanks for sharing.

  58. I’ve never seen or heard of this product. Sounds like something to keep in the home repair arsenal!

  59. Thanks for information on the Gorilla glue tape. It can be a great problem solver for many projects.

  60. Rochelle Brinson says:

    This is great. I love GORILLA products. Their heavy duty “duct” tape is amazing. Actually holds posters and signs to brick walls so tight I struggled to pull them off. I’m sure this tape is equally well made. Can’t wait to try it. I too have an air bed that is leaking and it isn’t a cheap one, has the built in pump. Will have to see if it fixes the leak.

  61. Deb Wostmann says:

    Great to know. I had no idea that product existed.

  62. Mary South says:

    Too bad about your new gutter but at least you have a cheap solution! Thank you for sharing! I will file this away in my handy solutions.

  63. Gorilla Glue is great so this tape should be a good solution for your gutter. I will use it to repair pool toys that spring a leak…which happens all too frequently.

  64. Wow! We use Gorilla glue for many repairs around our house, but I didn’t know about this tape. I’m definitely adding a roll of this to my hubby’s stocking!

  65. Linda Pawlak says:

    We have a leaky gutter also, and a leaky spot in the wall where the sewer pipe enters the house. Two jobs fixed with one tape. Brilliant!!!!!

  66. WOW I would not have thought about using it for gutters. This glue is really something. It works wonders for many different things. But to know that there is a tape is such a help as well so it holds is really a help.

  67. Jennifer Baron says:

    I will definitely try this for our gutters, thanks!

  68. Good to know! Thanks for the info.
