An easy, inexpensive way to repair a piece of metal gutter that has rusted through is to patch it. You can make small repairs using only plastic roofing cement. To repair larger holes, cut a patch from a piece of galvanized metal flashing.
SKILL SCALE Easy TIME REQUIRED You can patch a 2-foot section of gutter in about an hour. TOOLS Wire brush Abrasive pad Putty knife Tin snips MATERIALS Galvanized flashing for patches Plastic roofing cement
STEPS
		Begin by cleaning the area around the leak with a wire brush and water. After the area has dried, scrub it with an abrasive pad.
		Apply plastic roofing cement over the leak and feather it out on the surrounding area to flatten any steep edges in the repair.
		If the leaks are larger than nail holes, use tin snips to cut a strip of flashing (the same material as the gutter) wide enough to fill the area. Bend the strip to fit and embed the flashing in the cement. Feather out the cement around the edges of the repair.
