Aluminum siding is popular because of its affordability and look. Aluminum siding can be painted a number of different colors and holds paint well. Aluminum siding has its benefits, but it also has disadvantages. It can rust or be damaged in dangerous weather conditions. If you have a hole, tear, or another kind of damage to your aluminum siding, you can remove the damaged piece and replace it without ruining the rest of the siding.

Step 1 - Prepare

Before you start to remove damaged panels of aluminum siding from your home, you should know a few things. Cutting aluminum can be extremely dangerous, so it’s important to wear heavy-duty gloves and safety goggles throughout the duration of the project. Also, when you have a damaged panel of aluminum siding, it is not necessary to remove the entire panel; you can remove only the damaged part and place the new siding panel over the old one.

Step 2 - Score the Aluminum Siding

Locate the area of your aluminum siding that is damaged. You will use the utility knife to cut or score two vertical lines on either side of the damaged part of the siding. If you cannot cut through the aluminum with a utility knife and strength, you can use a screwdriver and hammer to get the line started. Cut the vertical lines with your utility knife to about two inches from the top of the siding panel.

Step 3 - Use Tin Snips

Once your vertical lines have been cut, you can begin making your horizontal cut across the length of the aluminum siding panel. Use tin snips to complete this task. Tin snips are used to cut sheet metal and come in a variety of different forms. Red and green handled tin snips are for cutting sheet metal in a curved fashion. Since you want to cut your aluminum siding straight across, you should opt for the yellow handled tin snips. Cut a line straight across the damaged piece of siding, again, leaving about 2 inches of siding at the top of the panel. This will be where you attach your new piece of siding. Also, cut down the vertical lines if you weren’t able to cut them fully with the utility knife.

Step 4 - Attach the New Aluminum Siding Panel

After you are finished removing your piece of aluminum siding panel, you’ll want to measure the space you have left and use your tin snips to cut a piece this size from the new siding panel. Using caulk attach the new aluminum siding panel over the hole where you cut away the damaged piece. Once the caulk is set and dry, you can paint your new siding panel to match the rest of your siding.
