How to Replace Aluminum Siding End Caps

Aluminum siding is durable and does not require a lot of maintenance to keep it in good shape. The most common repairs involve dents in the siding or the end caps. Repairing the damaged areas will protect the material underneath the siding and improve the value of the structure. You will only need a few simple tools and some time to replace the end caps. Read on to learn how to replace aluminum siding end caps.

Difficulty: Moderately Challenging

Instructions

Things You'll Need:

• Small pry bar
• Hacksaw
• Roof cement or silicone
• Hammer
• 1 1/4-inch aluminum nails

1. Remove the damaged end caps. Some of them may be stubborn and have to be pulled up and cut off with a hacksaw. Remove the nails, using the pry bar if necessary.

2. Remember when replacing the new ones, they go on in the same position as the ones you removed.

3. Examine the material under the end caps. If damage has been present for a while, there may be water damage, mold or rot. Make necessary repairs before replacing them.

4. Start at the bottom end cap and work your way up. Slide them in place with the bottom edges of the siding overlapping them at the top. Hammer aluminum nails into the tabs at the top of each cap.

5. Cut the nailing strip off the top cap. This should be the last damaged one you replace. Apply silicone or roofing cement to the back. Place the top of it under the bottom lip of the cap above it. Press firmly in place to make sure the silicone or cement has made good contact.

Tips & Warnings

• When you remove the end caps, work from top to bottom. To replace them, start at the bottom and work your way up.
