To help you handle such concerns with more ease, we’ve rounded up a few of the best ways to seal gutter seams. Check them out below.

No matter what the size of the leak is, the act of sealing gutter seams tend to always come with a significant amount of work.

The fact alone that you’ll need to go up to your roof to get things done instantly makes this task rather burdensome. But then again, with the consequences it comes with, trying to fix the issue at hand is always worth the effort.

On the bright side, however, sealing gutter seams isn’t that hard to do. Sure, it can be tricky, depending on the position of the leak, but the actual act of sealing the gap isn’t particularly hard to do.

If you need to patch one up at home, here are three ways how to seal gutter seams:

Method 1: Using a Caulk

Sealant caulk is possibly the most common fix for repairing gutter seams. Here’s how to fix gutter leaks with it.

What You Need:

  • Your choice of caulk sealant.
  • A caulking gun. (if necessary)
  • Putty knife.
  • Sponge or any absorbent dry cloth.
  • Any tool for removing junk from your gutter.

What to Do:

  1. Locate the exact location of the leak. This can be quite easy to spot as it often involves broken or peeling caulking.
  2. Clean your gutters. Remove the dirt and debris that has accumulated in it, especially in the area where the leak is.
  3. Use the sponge or dry cloth to dry the area. You should also air dry it for a couple of hours to make sure that it’s thoroughly dried. If the weather doesn’t permit you to dry out the gutter, get a water-based caulk instead then dry the area as much as you possibly can before proceeding to the next step.
  4. Apply a string of caulk along the seams from the inside of the gutter to the outside.
  5. Using the putty knife, smoothen out the sealant. Doing so will help minimize the restriction on the flow of the water on your gutters.
  6. If there’s a gap between the seams, apply more sealant in the space and try to push it in to fill the gap.

Method 2: By Patching

If there’s a large gap or hole in between the seams of your gutters, patching them up would be the best fix. Here’s how to do it.

What You Need:

  • Your choice of caulk sealant.
  • A caulking gun. (if necessary)
  • Asphalt roofing cement. (alternative to caulk)
  • Putty knife.
  • Dry cloth or sponge.
  • Any tool that can help remove debris from your gutters.
  • A piece of steel that is similar to the material used on your gutters.

What to Do:

  1. Locate the leak.
  2. Clean the area where the leak is. Remove the debris using your tool of choice.
  3. Dry out your gutters. Wipe the area with the leak and then let it air dry for a couple of hours.
  4. Again, if the weather doesn’t permit you to dry out your gutters, use a water-based caulk instead.
  5. Apply a generous amount of caulk into the area where the leak is. Place the piece of steel on top of it then apply more caulk. You can use a putty knife to evenly distribute the caulk. Alternatively, you can also opt to use asphalt roofing cement instead of caulk in this step.

Method 3: Using a Spray

For hairline gaps and leaks that need a quick fix, a sealant spray would come in handy. Here’s how to seal gutter seams with it.

What You Need:

  • Spray-type sealant.
  • Clean rag.
  • Cleaning solution of your choice.
  • Another dry, clean rag.

What to Do:

  1. Locate the problem area.
  2. Clean and prepare the area for sealing. Remove the debris from your gutters then dry it out.
  3. Wipe the area down using a rag with the right cleaning solution for the material of your gutter. Wipe it dry.
  4. Shake the spray can vigorously for about a minute then aim the nozzle on the leaking area. Spray accordingly. Let it dry and cure for 24 hours.
  5. Spray the second coating following the previous step. Let it dry and cure for 48 hours.

Extra: Replacing Your Gutters

There will come a time that repairing your gutters will not be enough to stop it from leaking. In this case, replacing your gutters will be the best way to fix the issue.

As one would expect, gutter replacement isn’t an easy task. It can be a big job, even if you’re not replacing all of your gutters. It will still require a good deal of construction so you have to be ready to take on this job.
