Aluminum Siding Repairs

Expert do-it-yourself tips for repairing common aluminum siding problems, as well as instructions on how to replace entire panels and flash siding.

Though aluminum siding won’t rust, rot, blister, burn, or get eaten by termites, it can dent and scratch and in time fade and corrode. Fortunately, repairs are fairly simple, even including how to replace a damaged panel.

Use 100% acrylic latex finish to revive a finish on aluminum siding.

Repairing Corroded or Scratched Aluminum Siding

If aluminum siding has corroded or been scratched down to the bare metal but the panel is still intact, it can be repaired. Lightly sand the problem area, apply a metal primer, and allow the area to dry. Then apply 100% acrylic latex paint.

Fixing Dented Aluminum Siding

Repairing a dent in aluminum siding is a little bit like doing body work on a ca–in most cases, you can simply pull the dent out. Here’s how to do this:

1Drill a 1/8-inch hole into the center of the dent.


2Put a washer onto a 1-inch self-tapping screw, and drive the screw into the hole.

3Gently pull the washer until the dent pops back into position.


4Remove the screw, and then use plastic aluminum filler to patch the hole.


5Lightly sand the patch, if necessary, and touch up with paint that matches the siding.

Refreshing Faded Siding

The factory coating on most metal siding is very durable, but the surface can fade over time. Sometimes power washing the siding is enough to refresh it; other times the siding may need a new coat of paint.

When painting, don’t use oil/alkyd-based paints or dark colors, which can cause the metal to expand excessively. Instead, choose a light tone of high-quality 100% acrylic latex paint. Most houses look best with the slight luster of an eggshell finish.
