What are the disadvantages of using aluminum strips for siding?

Aluminum siding, while durable and lightweight, has several disadvantages. It can dent easily due to its softness, which may require frequent repairs. It also lacks insulating properties, leading to increased energy costs as it doesn't retain heat well. Additionally, aluminum siding can be noisy during heavy rain or hail, and it may expand and contract with temperature changes, causing warping or gaps. Furthermore, it can be more expensive than some other materials, and its reflective nature may lead to a less aesthetically pleasing appearance compared to other siding options.
