How To Fix Galvanized Gutters

Galvanized gutters for roofs are a popular choice because they can last two decades or longer since they don't crack like plastic or wood types. However, you still should check them for leaks, although they have a protective zinc coating. It doesn't mean you have to replace the gutters if you spot a hole. You should be able to fix the hole in galvanized gutters by following these steps.

Prepare to Fix the Hole

To fix a hole in galvanized gutters, gather:

  • work gloves
  • A-frame ladder
  • rags
  • garbage bags
  • putty knife
  • steel wool pad 
  • wire brush 
  • gutter scoop 
  • new clips (optional)
  • wire cutters or tin snips
  • roofing cement
  • rivets and rivet gun (optional)
  • caulk and caulk gun
  • rubber spray sealant
  • steel sheet or gutter patch

Stand an A-frame ladder on a steady surface, and get someone to hold it for you. A-frame ladders are suggested because the ladder doesn't need to lean against the gutter to avoid damaging them. 

Use the scoop to remove leaves and debris, and discard them in garbage bags. Scrub the interior with a  damp wire brush, wait for the gutters to dry, then wipe the surface with a steel wool pad. As you clean, take note of separated seams and missing connectors, which are commonly rivets or clips.

Patch Seams and Connectors

Reinsert missing rivets or clips. Slide a new clip in place of the old one, or attach a rivet with the rivet gun in the same hole. Avoid using sheet metal screws to hold gutter seams together, because the screw tips can allow dams to build.

Cut the tip of the caulk tube off at a forty-five-degree angle, and load it into the gun. Caulk the inside of cracked seams and gutter ends, then let it dry. 

Fix Holes

To fix holes smaller than the diameter of a nail head, roughen the surface by rubbing it with a wool pad. Use the putty knife to spread the cement over the hole, and let it dry.

To fix larger holes, cut a piece of metal flashing or a steel sheet with tin snips or wire cutters. The material should be the same material as the gutters. Spread some roofing cement on the bottom of the cut piece, then push it into place over the hole. Add a bead of roof cement around the perimeter, keeping the edges feathered.

After the patch dries, shake the can rubber sealant, and mist it over the repaired areas, holding the can eight inches away from the surface. The sealant will help form a waterproof seal. To learn more, visit a website like
