All buildings need an effective way of dealing with rainwater run-off from the roof. With such a wide range of gutter and downpipe styles in the market it’s fairly straightforward to find the rainwater systems that suits your building project. The most important criteria is that the system can deal with rainwater runoff, including a deluge from a thunderstorm. The gutters, downpipes and brackets also need to cope with the loadings imposed by snow and ice build-up. We offer a wide range of rainwater systems that can be used for residential, commercial, retail, leisure and healthcare buildings amongst others.
Most manufacturers offer a chart to calculate the size and type of rainwater systems needed based on maximum effective roof area. This takes into account the roof pitch and roof area to give you a list of suitable rainwater systems. For example, a large steeply pitched roof will result in rapid rainwater run-off and so may require a deep ogee gutter and large
diameter downpipe to cope with the flow of rainwater during a rainstorm.
Identifying a system that is low maintenance will reduce the amount of working at height required and keep facilities budgets low. That means selecting a material that won’t discolour – and here a UV stable material is best – or crack during the hot summer months due to expansion and contraction.
When referring to a rainwater system it usually means gutter, downpipe, brackets, hoppers, fascia brackets, drain adaptors and accessories. They can be made from a variety of different materials such as PVC-u, seamless aluminium or steel gutters. By far the most popular, due to its cost-effectiveness, low maintenance and long life, is PVC rainwater systems.
It is the gutter profile that often makes a rainwater system appealing to a building owner. There are several long-established gutter profiles such as half round, ogee, square and deep flow. Ogee is a popular choice because it has a high capacity for rainwater whilst its appealing aesthetics look great on residential properties.
There is more to selecting a rainwater system than meets the eye. That’s why it’s worth speaking to our team so that they can guide you through the process, making sure that your project runs smoothly from start to finish.
