Gutters prevent rainwater from pouring off of your roof in sheets. Since gutters sometimes handle heavy loads of water, they may rust or crack. To repair your broken gutter, use caulking to seal the cracks. The process is a lot cheaper than hiring someone to repair it for you, or completely replacing the broken gutter with a new one. You only need a few household tools to start fixing your broken gutter.

  1. 1

    Locate the exact spot where the gutter has been broken. Trace the leaks to determine where the water is pouring or dripping from. These are normally tiny holes or cracks on the gutter. Climb up to the roof, using a ladder if necessary, to get a better view of the broken gutter.

  2. 2

    Cover the small holes or cracks using premixed cement, applying it with your putty knife. Cover the hole with enough cement and smooth the excess away using your putty knife. This will make sure that water runs smoothly through the rain gutter.

  3. 3

    Cut a metal sheet with a saw to a size slightly larger than the hole or crack in the gutter. Use the same type of metal that the gutter is made of. Apply roofing cement at the ends before pressing the cut sheet gently over the hole. Apply more roofing cement using your putty knife, making sure that the layer is still thin enough not to obstruct the flow of water.

  4. 4

    Apply silicone caulking compound to the remaining cracks as well as to the joints of the gutter to prevent further leaks or damage. Use a caulking tool to caulk the outside and inside of the gutter to provide a stronger seal.
