Metal Gutter Repair: How to Patch a Hole
If your metal gutter has developed a hole, you should definitely repair it.
A leaky gutter may seem like a minor annoyance, but if rainwater drips against your house instead of being directed away from it through a downspout, the water could penetrate your home—and undoing water damage inside the home is a challenge.
Fortunately, patching a hole in a metal gutter is a simple job requiring only a watertight patch. Here are the best three ways to approach it.
Patching a Metal Gutter: Project Overview
Time: less than 1 hour
Warning: When working from a ladder, be sure it is stable and on solid ground.
Things you’ll need:
- leather work gloves
- clean cloth
- eye protection
- wire brush or steel wool
- tin snips
And one of the following sets of items:
- small piece of wire window screen and roofing cement
- small piece of metal flashing and roofing or flashing cement
- small piece of metal flashing, pop rivets, pop rivet gun and silicon caulk
Prepare the Gutter for Patching
A patch needs to be applied to a clean surface, so first clean the area around the hole. The easiest way to get rid of any old leaves or twigs in the gutter is to take them out by hand, so be sure to wear strong leather work gloves.
Once the gutter has been cleared, clean around the hole to get rid of any corrosion by scrubbing the area with a wire brush or a piece of steel wool. When that is finished, wipe the area with a clean cloth.
Method 1: Patching With Window Screen
- Cut a piece of scrap wire window screen about 1 inch bigger than the hole.
- Spread roofing cement all around the hole, then press the screen piece into the cement and finish by spreading more cement over the screen.
- Look to see if there are any uncovered holes in the screen. If there are, spread on more roofing cement.
Method 2: Patching With Metal Flashing
- Cut a piece of metal flashing larger than the hole.
- Spread some roofing cement on the back of the flashing and place it over the hole.
- Wipe away any cement that oozes out around the edges.
Method 3: Patching With Rivets
- Cut a piece of metal larger than the hole.
- Set the patch over the hole and then, working inside the gutter, drill at least two pilot holes through both the patch and the gutter.
- Apply a bead of silicon caulk around the edge of the big hole as well as around the edge of the metal patch.
- Set the patch in place inside the gutter and secure it using pop rivets through the holes.
- Finish the repair by running a bead of silicon caulk around the edge of the patch and smoothing the bead with your finger.
