Aluminum

Aluminum siding weighs more than the newer sidings available on the market today and that makes it more time consuming to apply to your home and more costly. Aluminum siding has the baked on enamel finish, and if scratched, the paint will be removed and the bare metal below will be visible. However, due to the expansive properties of vinyl, aluminum siding takes paint better if you ever decide to re-paint. As far as maintenance goes it needs to be cleaned once a year, and repainted every so often typically 5-10 years.
