Aluminum Siding - Cost

Aluminum is more expensive than vinyl, but it is readily available in a variety of colors. Aluminum is more labor intensive to install and you will pay more for installation. As with vinyl, aluminum expands and contracts but to a lesser degree. If you need to replace a piece of damaged aluminum you will need to remove every piece below it and one piece above it to do this.
Aluminum generally increases the value of your house more than vinyl.
