What are the differences between aluminum and copper siding?

Aluminum and copper siding differ in several ways. Aluminum is lightweight, corrosion-resistant, and requires minimal maintenance, making it a popular choice for durability and low cost. It is also available in a variety of colors and finishes. Copper, on the other hand, is heavier and more expensive, but it develops a natural patina over time, which can add a unique aesthetic appeal. Copper is also highly durable and recyclable, and it does not require painting. However, it is more prone to denting and can be more challenging to install. In terms of thermal performance, copper conducts heat better than aluminum, which can be an advantage in certain climates.
