Learning how to repair holes in copper gutters can save you on replacement costs and get your gutters operational more quickly. Copper gutter repair can be done with a few hand tools and the correct materials.
To repair copper gutters, you’ll first need to determine how your copper gutters were assembled and then devise a plan.
Your copper gutter system may use rivets, solder, adhesive, or elastomeric caulk for adhesion, so you’ll want to use the same materials for your repair.
Our gutter experts will provide a step-by-step guide for repairing holes in copper gutters using a kit or other repair materials. We will discuss the proper way to repair holes in copper gutters by first cleaning, then filling, patching, and painting the repaired sections.
Step 1: Cleaning the Damaged Area
Holes in copper gutters are often the result of weather damage, impacts, and corrosion, which can lead to water damage, mold, and erosion of the ground.
The first step in understanding how to repair holes in copper gutters is to prepare the damaged area by cleaning it as thoroughly as possible.
Here are a few tips for cleaning your copper gutters before making repairs:
- A soft cloth or sponge and warm, soapy water does an excellent job of removing the oils that could weaken the adhesion of the patch.
- Use a stiff brush or a scraper to remove any loose paint or caulk from the hole. Try to flatten any burrs in the metal, but wear thick gloves.
- Apply a mildew remover or bleach solution to the surface. Allow the solution time to work as directed, and rinse thoroughly.
- If the weather is calm and cool, use a dry cloth or a towel to dry the area thoroughly before moving on to the repair.
Step 2: Filling Small Holes
Copper gutter repair involves sealing even tiny holes, such as noticeable gaps or cracks. This will prevent minor leaks from becoming more severe and allow moisture to penetrate the exterior of the house.
Here are a few handy tips for filling in small holes in copper gutters the professional way:
- Select a suitable filler for your copper gutters, such as waterproof caulk, epoxy putty, or solder. Each method will require a different skill set, so if you’re unsure which to use, hiring a local pro is the next best option.
- Choose the appropriate filler color for your copper gutters, such as matching the original color or choosing one that is slightly lighter. The amount of patina, if any, will vary from one area to the next, so you might want to leave the option open to alter the shade.
- Apply the filler as directed, often using a caulking gun, a putty knife, or a soldering iron. Wear the appropriate personal protective equipment (PPE) to protect yourself from the sharp tools and heat.
- Apply enough filler to fill the hole completely and slightly overflow, as the material will shrink as it dries.
- Smooth and shape the filler following the directions, or smooth it with a damp sponge.
- Ensure the filler has time to dry and cure according to the manufacturer’s instructions before sanding or painting.
Step 3: Patching Large Holes
Patching holes will restore the function of your copper gutters and save you money. When you repair copper gutters, it’s essential to use the correct materials. Some repair kits are adhered with glue, some use rivets, and others are soldered.
Follow the directions with your kit, but here are a few general rules to follow:
- Find the correct patch for copper gutters, such as a copper gutter repair kit, a spare piece of copper sheeting, or other metal flashing.
- Select the appropriate size and shape of the patch, which is usually slightly larger than the hole and matches the gutter profile and shape.
- Trim the patch with tin snips, file, or other tool to remove any burrs from the edges.
- Apply the adhesive or solder to the back of the patch and press it firmly over the hole. Wear disposable gloves for this step, as the adhesive can be difficult to remove from your skin.
- Secure the patch as the manufacturer recommends, including using two patches. In some kits, the hole is sandwiched between two sheets of copper, one on the inside and one on the outside.
Step 4: Painting the Repaired Area
Your copper gutter repair can have a significant effect on its appearance. The goal is to make the repair hard to see, so some creativity and patience go a long way toward a successful job.
Here are a few more tips for painting your copper gutter repair to help camouflage it:
- Experiment with a few options until you find one you like. You can test your colors on the inside of the gutter and practice if you need to.
- Select the right type of paint for copper gutters, such as acrylic latex paint or copper patina paint. Some products even let you tint the patina to make it more unique.
- You can change the patina tint or paint an opaque color onto the copper gutters, matching the shade.
- If you’re retaining the original shiny finish, you’ll need to be especially accurate with your patch trimming. In this option, the metal inside the gutter is essentially a backer for the outer repair. Instead of slightly overlapping the gutter, the patch is made identical to the hole, then soldered into place and polished.
- If using opaque paint, spray primer (if needed) on the surface before painting to improve adhesion and coverage.
- Avoid using a paintbrush or roller if the surface will be glossy. This option is acceptable for low-sheen paints that limit light reflections, like satin or matte. Use a sprayer if the sheen will be glossy, as brush and roller marks will show through the reflections.
- Apply two coats of paint (or as directed) and allow enough flash time for each coat to dry.
