Standing Seam Metal Roofing - Roofing and Cladding System

Catnic - standing seam metal roofing

A popular and contemporary specification choice, standing seam metal roofing has multiple benefits for both new and refurbishment projects, so it’s likely to be part of many roofing contractors’ repertoires. Here Richard Price, Technical Director at Catnic, deconstructs the pre-coated standing seam metal roofing specification to look at some of the positive environmental impacts it offers.

Fundamental to any project where there is an environmental driver – and let’s face it, best practice means most fall into this category – the roofing system installed must support the energy requirements of the building and its occupants. In other words, it needs to conserve heat and minimise energy loss in winter and during the warmer summer months it must protect the internal environment from overheating through solar gains - thereby supporting the mechanical cooling system in place.

Specifiers will be striving to achieve the highest BREEAM levels possible. Therefore their choice of roofing material has to combine energy performance with the roofing contractors’ demand for a system that is simple (not too time consuming, costly or hazardous) to install and one that will last a long time with as little maintenance required as possible. All this has to be encapsulated in a system that makes a positive contribution to the aesthetics of the project and the wider roof-scape of which it will form a part.

Roofing contractors and those responsible for the specification of roofing systems will be no strangers to the weight implications here. This is particularly pertinent to retrofit projects where a new roof might be installed directly over the old one, for example in a flat-to-pitched roof conversion.

Here a standing seam metal roof, with its lighter weight and simplified onsite logistics, offers a host of benefits over traditional roof tiles. The lighter weight makes handling easier, whilst pre-punched fixing holes and a range of standard trims means installation of standing seam metal roofing such as the SSR² Roofing and Cladding system is quicker and the delivery of the project is much faster as a result.

The SSR² Roofing and Cladding system is not reliant on roll forming or seaming on site, providing a real advantage for contractor teams to ensure workmanship levels remain consistent and that there is a robust approach to quality control. The roll formed standing seam is created off site so it arrives ready to install, helping to smooth the onsite process.

For a truly environmental roofing specification the material choice is a crucial one. The full life cycle of the roof needs careful consideration, and this includes the legacy of the materials themselves.

Catnic - Richard PriceA Green Guide recognised system delivers peace of mind when it comes to the environmental credentials of the product and the project can maximise credits available under the Responsible Sourcing of Materials in BREEAM. Combining the material sustainability of the roof with its operational performance will optimise its environmental credentials. For example when a standing seam metal roof is integrated with solar panels or other environmental solutions, such as a rainwater harvesting system, then a well-designed roof not only conserves energy within the fabric of the building efficiently, it is also integral to the production of energy, for consumption on-site.

However the materials installed not only need to perform environmentally they need to stand the test of time too. The SSR² Roofing and Cladding system, which is BBA certified and designed to last in excess of 40 years, is manufactured from Colorcoat HPS200 Ultra®. This guarantees durability without compromising the sustainability of the roofing system.

So the energy performance, ease of handling and installation, and materials are all key indicators in the environmental benefits a roof can deliver. The specification and installation of a system that fulfils legislative requirements, at the same time as supporting the environmental ideals of the project, must be a holistic process because the roof also needs to contribute in a positive way to both the design of the building and its neighbours. Providing the contemporary look prized by architects and end clients, a standing seam metal roof can be installed to pitches as low as 5°, making it ideal for both new and refurbishment projects.

Harnessing all the performance, aesthetic and installation demands of a roofing project in one system not only simplifies the process for the roofing contractor, it can also help to drive out cost. At Catnic we are seeing material cost reductions of as much as 40% in some cases as a result of standing seam metal roofing specification. This is because pre-coated steel systems offer serious cost benefits over zinc and aluminium alternatives.

Taking a holistic approach to roofing specification requires a view of the bigger picture: the long term, maintenance projections and end of life considerations, at the same time as an eye for the details: the overall design appearance, the intricacies of installation and site logistics that can all enhance a project’s environmental agenda. Pre-coated standing seam metal roofing offers roofing specifiers and installers a viable solution that sustainably stacks up.
