Aluminum awnings serve a dual purpose: keeping a space shaded and wind protection when folded down over a window. Though aluminum is extremely durable and weather resistant, it can be punctured or cracked. If this occurs on an aluminum awning attached to your home's exterior, you have two options: replace the aluminum awning or repair it yourself. The latter of the two is less expensive and is not difficult to do.


Step 1

Put leather gloves on to protect from cuts while working with the aluminum awning. Place a ladder next to the aluminum awning.

Step 2

Clean any grime and/or rust off the aluminum awning with a wire block brush to have a clean surface for the patch to stick against.

Step 3

Make the damaged area square using aluminum snips.

Step 4

Cut a square section out of a piece of aluminum with the snips about two to three inches larger than the hole in the awning.

Step 5

Place the aluminum patch over the hole in the awning and tape down in place with butyl tape.


Step 6

Fasten screws around the outside edges of the patch with a screw gun and stainless steel screws--putting at least two screws in each side.

Step 7

Caulk around the edges with silicone caulk using a caulk gun, wiping away any excess silicone with a damp cloth. Allow the silicone caulk to dry for approximately 30 minutes.

Step 8

Spread roof coating over the entire patch with a paint roller. Let dry as long as directed by the manufacturer.
