As aluminium will not rust, it’s the ideal choice for a long-term gutter system. When replacing or installing a new rainwater ., system, you want it to last for decades. Aluminium is extremely durable, with a life span of around 30 years. Aluminium gutters will not shatter or crack when experiencing temperature changes. Aluminium often comes in a continu- ous spouting form — there are no joints, which prevents the ap- pearance of leaks and cracks. Apart from the regular clean- ing of debris and leaves from the gutters, there is usually little-to-no maintenance required.
