Longboard aluminum siding is manufactured out of aluminum sheet stock, which is often chemically coated for protection and painted for aesthetics, and sometimes with enamel on the outer surface to make desired patterns. The aluminum is placed on wooden frames which are then erected into houses or other structures. When aluminum siding gets older, it gets softer and loses its rigidity, but can also dent if something gets thrown up against it. It can be very dangerous and therefore aluminum siding should not be used by some people or animals, especially children who may be careless enough to bump into it while playing.
As mentioned above, aluminum siding can crack when it gets hit with hail or something heavy. However, there is an interesting way to make aluminum panels that will last much longer than hail and won't crack when hit by falling objects. You need to have your metal structure covered completely and have a sort of layer of protective metal over the top. This is usually made of aluminum foil. It protects the aluminum from things like hail or falling objects, and keeps it from cracking.
One of the most common problems for homeowners with aluminum siding that needs to be replaced is that of peeling paint. Sometimes this can be solved by simply scraping off the paint and sanding the areas heavily so the new paint sticks. Other times, however, the homeowner will have to remove all the old peeling paint and get a new application put in place before painting. When removing the older application, it is a good idea to take apart the old piece of metal and use that as a pattern for the replacement piece.

Sometimes, though, a homeowner might actually prefer removing aluminum siding entirely and buying a completely new house. There is an interesting technique for doing this, though. It involves actually building a shed out of the old pieces of metal. Here's how it works.
First, remove the aluminum siding from the sides and the attic. Thoroughly clean up any leftover dirt on the pieces using a vacuum. Get some nails and some wood shims and start to build a shed. When you've finally finished this, get some nails and some shims and start to hammer the new vinyl siding into place. Replace the metal flashing around the perimeter of the shed.
Once you've gotten this new vinyl siding down pat, you can put some new wood siding on the outside walls. Remember to secure each piece of wood siding to its corresponding nail. Once this is done, you can then install the exterior walls. Make sure that you screw these things into concrete. That way, they will be permanent and won't be subject to quickly wearing away due to the elements.
