Environmental Considerations of a Roofing System

In recent years, it has become essential to ensure that a roofing system meets a multitude of environmental requirements. The way we construct and refurbish buildings can have a significant impact on the surrounding environment; and as an industry there is a duty of care to ensure every project benefits from an eco-focus. When taking a sustainable approach to roofing specification, it is important to take into account the life cycle analysis of the product, from cradle to grave.

Environmental Impact

Ensuring that all materials resourced are 100% recyclable is a good starting point when specifying roofing system, so it is not disposed of in an environmentally harmful way - such as via landfill - at the end of its useful life. Assessing the method of manufacturing raw materials - the level of emissions they release and their impact on the landscape – is also beneficial, whilst also looking at the fuel consumption of transportation.

To maximise credits under the Responsible Sourcing of Materials criterion in BREEAM, look for roofing materials that are BRE Green Guide compliant. In addition to BREEAM, roofing professionals looking to employ systems with the highest environmental and sustainable standards should also check for compliance with ISO 14001 and BES 6001 certification, as well as BBA certification. These certifications insist that product manufacturers prove that the products they release to market have been responsibly sourced, demonstrating a sustainable building approach.


The longevity of a system also contributes to its sustainability. The more durable a product is, the less resources it will require in maintenance and replacement throughout the life span of the building. Because of this, it is best practice to specify roofing systems capable to withstand the elements and meet all current legislation for wind loadings, weather tightness and fire performance. Pre-coated steel systems often perform well in this regard, with Catnic’s SSR2® Roofing and Cladding System recognised by independent BBA certificate that the material used to manufacture SSR2® will have durability for a period in excess of 40 years in normal urban, suburban and rural environments.. In addition, standing seam systems that incorporate a multi-layered coating deliver excellent protection against corrosion, further ensuring the longevity of any roofing or cladding systems.

The SSR2® Roofing and Cladding System is a perfect solution for those specifying an eco-focused roof. It is BES6001 certified and made from 100% recyclable materials, offering a carbon footprint that is three times lower than some of the leading eco-designed urban roofing products. Manufactured from Tata Steel Colorcoat HPS200 Ultra, the panels are designed to last, guaranteeing durability whilst offering the aesthetic of zinc or aluminium, much desired in the architectural community.

As the system continues to increase in popularity, Tata Steel has launched Confidex® Home Guarantee – which is valid for 25 years – to provide homeowners with assurance of the building material’s performance.

Exposure to sunlight, extreme weather or coastal environments are all critical external factors that roofs and walls have to resist to maintain performance over time.  Tata Steel is so confident in the performance of Colorcoat Prisma® and Colorcoat HPS200 Ultra® based on extensive testing of  both products in laboratories and weathering sites around the world, that Confidex® Home is offered irrespective of where the material is installed (roof or walls) or where the home is situated.
