Even though vinyl siding is increasingly common, aluminum is still one of the most common siding materials. It does still have certain advantages to other materials, but it is not without its shortcomings.
Aluminum siding is fairly durable, and can last for decades. It is not susceptible to rust, rot, fire, water or termites. It is also paintable.
On the other hand, if there is any type of damage to the siding, aluminium can prove very difficult to repair, and unfortunately, any dents or scratches will show up very easily since it can reveal the metal underneath the paint.
Repainting the siding, which will be necessary at least every 10 years, if not more often, can be fairly difficult.
In some areas there are requirements that aluminum siding is grounded, since it can conduct electricity. As with all siding, it should not be in contact with the ground, since this will increase the risk of damage to the siding and will not allow access to the underlying structure for inspection.
