Aluminum siding is a very versatile building material, which is why it has been used in construction for about 80 years. Aluminum is resistant to damage that many other materials can’t handle, such as rot, fire, bugs and water damage. It will last a long time if cared for properly. Aluminum can be painted to get a look that you like, but the paint would need to be reapplied every 10 or so years if you want it to remain looking good.
One downside to aluminum is that it dents easily, especially when you save money by investing in a thinner material. If it does dent, the only solution that will look best is to replace the panel, but unfortunately, it is difficult to remove just a single panel, you might end up needing to replace more than one. Using a thicker option will make it less likely to dent, but of course this will also cost you more.
