Examine the gutters carefully to locate holes and cracks in the gutter surface.
Take a wire brush and remove loose rusted metal from around the hole in the gutter. Clean this debris from the gutter before proceeding.
Cut the edges of the rusted metal from the affected area until you reach clean metal. Remove the pieces, and discard.
Wipe the surface of the affected area clean with a cloth.
Cut the patch for the hole, making it a few inches larger than the hole to overlap onto solid metal.
Position the patch in place, and drill hole for screws through both the patch and the gutter material. Remove the patch.
Spread roofing cement on the gutter to hold the patch, spreading it slightly beyond the where the edge of the patch will be. Press the patch into position
Insert screws into the drilled holes, and secure.
Seal the edges of the patch with silicone caulk to prevent leaks.
Things You Will Need
- Wire brush
- Tin snips or metal-cutting shears
- Metal for patch
- Caulk gun
- Roofing cement
- The website JonEakes recommends using steel wool to remove the grime that solidifies on gutter surfaces to provide a clean base for the patch.
- Gutter can be galvanized steel, aluminum, vinyl or copper. Use matching material when patching your gutters. You can buy small pieces of metal or plastic at hardware or home improvement stores.
- You might have to bend the material to fit into the area where the gutter is damaged. Use pliers and a hammer to mold the metal into the correct shape to fit into the gutter.
