Tell-Tale Signs of a Leaky Gutter

Gutter problems left unrepaired can cause major issues to your home, so knowing what the signs of a gutter leak look like means you can catch it as early as possible to prevent further damage (and further costs).

If you see any of these signs, it’s time to take action and figure out how to fix your leaky gutter before more damage is done. A professional inspection can diagnose the issue and determine if it’s your gutters or roof or another issue.

How to Fix Leaking Gutters (Step by Step)

There are a few ways to pinpoint and fix leaky gutters. The best way to find a gutter leak is to inspect the gutters after a rainfall to see where the water is spilling over or dripping down. But you can also do a simple test by flushing your gutters with a hose and seeing where the water leaks out.

Once you know where the leak is, determining how to remedy the situation is the next step. To patch a leaky gutter, follow these steps:

Step 1: Gather the Materials or Tools You Need

Step 2: Prepare the Gutter for Repair

Clear the gutter of any debris and wash it off with soap and water to have a clean working surface. If there is any old sealant or caulk, use your razor blade or putty knife to remove it.

Step 3: Prep Sealant if Necessary

If you’re repairing your gutter leak using sealant over a small crack, prep your sealant according to the instructions. Some of the best gutter sealants on the market include:

  1. Liquid Rubber Waterproof Sealant
  2. Gorilla Waterproof Patch and Tape
  3. DAP Crystal Clear Gutter Sealant

Step 4: Apply the Sealant

If you’re using sealant, apply it to the gutter leak following the instructions on the package. Start by caulking any cracks or holes and then use your putty knife to smooth out the sealant. If you’re using tape, apply it over the crack or hole, making sure to press it down firmly so it adheres securely. A combination of caulk, sealant, and waterproof tape can make your repair extra strong.

Step 5: Let the Sealant Dry and Cut Off Excess

Allow the sealant or tape to dry completely before moving on. Once it’s dry, you can use your razor blade or putty knife to cut off any excess material. If you are placing waterproof tape on top, make sure it’s fully dried before doing that extra step.

To replace a leaky or damaged gutter, follow these steps:

If your gutter is damaged beyond repair, replacing the entire thing is going to be your best bet at resolving the leak and stopping it in its tracks. If this is the case, you can easily remove the section of damaged gutter, and replace it with a new piece.

If you know your gutter size and brand, this should be a breeze. If you’re unsure, ask the contractor who installed your gutters, or bring the damaged piece with you to the hardware store to ensure you get the right fit.

Step 1: Purchase a New Gutter Piece— Cut to Size

Using tin snips, cut the new gutter piece to size, making sure to leave about an extra inch on each end. And always remember: measure twice and cut once. The last thing you wanna do is cut your gutter too small and have to buy another replacement piece.

Step 2: Remove Your Damaged Gutter

Carefully remove the section of gutter that has the leak, being mindful to not damage any other sections of the gutter. When detaching your connector pieces, remove any sealant or tape first, then unscrew the fasteners.

Step 3: Connect Your Gutters

Using the same sealant or tape, as well as any new connector pieces, screw your gutters back together, making sure they’re securely attached. If you’re unsure of what size or type of connector piece to use, ask a professional at the hardware store.

Step 4: Use a Hose to Ensure Waterproof Seal

Once you have all your gutters reconnected, use a hose to test the repair. If water starts leaking out of any other areas, you may need to add more sealant or tape. If everything looks good, give yourself a pat on the back—you just saved yourself from getting further water damage!
