Choosing a rainwater system ultimately comes down to the needs of the buyer and the requirements of the building. While they may be one and the same, the onus is on the buyer to thoroughly investigate which guttering is going to be the most superior option, particularly when designs vary considerably. High capacity drains are a natural option for those larger facilities with increased roof areas which tend to catch more rain. The amount of rainfall in the area will also be a telling factor. Having bespoke gutters fitted can bring adaptation to more unique building structures while also providing the same level of performance. On the other hand, style is important as well – a traditional cast aluminium option being the perfect option for those older buildings which will invariably need their drainage bringing up to date, while sleek discreetly fixed aluminium gutters are great for commercial spaces.

Whichever type of gutter is chosen, knowing the life expectancy and the amount of maintenance that will be needed will have a large impact on deciding to invest. The life expectancy does however change with where the building is situated. Those which are in rural and suburban areas can last for up to 40 years, but this will be cut drastically in industrial and marine areas where the air contains other more corrosive elements. With box, deep run, moulded and ogee designs typically being the shapes on offer, finding the right look should only be a matter of choice.
