Step 1

Drill Rivet Holes for the Gutter Splash Guard

  • Drill 1/8-in. holes through the splash guard and the gutter.
    • You can find these precut gutter splash guards (about $3) in brown and white aluminum at a home center, but you could easily make your own out of aluminum or sheet metal and spray paint them to match your gutters.

Step 3

Fasten the Rivets

  • Place the pop rivet tool over the shaft of the rivet and squeeze the handle once or twice to compress the rivet and break off the stem.
    • If you don’t own a Pop riveter, attach the guards with 1/2-in. sheet metal screws instead.
