Sustainability Commitment

Our journey to net-zero carbon by 2032

Architectural Manager

Roofing with a positive impact

We are proud that our work allows us to impact people’s lives positively, but we are acutely aware of our industry’s environmental impact on the planet. 

The road to net-zero can be daunting, and with construction playing such a pivotal role in helping to achieve these aims, we wanted to find a better way to support our customers and their projects for the future.

As industry leaders, we believe we are responsible for spearheading positive change, introducing best practices throughout our approved contractors and helping lead our industry to do the right thing.

Our Vision

We will be net-zero carbon by 2032, promoting innovative sustainable waterproofing systems, responsible sourcing, and circular economy principles that maximise the value of the materials we use and minimise life cycle waste. 

Through our long-standing partnerships, we will provide a lasting positive social impact on the communities in which we operate. We will put our people and contractors at the heart of everything we do, supporting their professional development to provide trusted technical expertise in a fair, inclusive, and respectful culture, promoting equality, diversity, inclusion, and good well-being.

We have prioritised four critical areas that significantly impact carbon and climate change; resource efficiency; people; and social value. Each key pillar of change has a vision statement of where we want to be, including the pledges we commit to achieving to reach our vision and targets, and the critical stepping stones we will take to fulfil them.

The 4 Key Pillars of our Sustainability Commitment

With our Sustainability Commitment, we will embed sustainability into everything we do by reducing our carbon footprint and our customer’s operational carbon. As a responsible and trusted building envelope partner, our customers can expect a long-term commitment from us that fully supports and enables their environmental initiatives.

Addressing our fundamental areas for change, we considered a broad range of environmental and social aspects when developing our Sustainability Commitment, which enabled us to focus on our customer’s critical environmental goals alongside our fundamental employee-owner stakeholder objectives.


We will reduce greenhouse gas emissions throughout our business and supply chain. By continuously developing our service and systems, we will support our customers to reduce their operational and whole-life carbon whilst maximising the environmental benefits of their roofing assets.

Resource Efficiency

We will reduce our waste to landfill and increase the use of recycled, reused and recyclable materials within our projects. We will provide our customers with transparent data regarding our waste management, resource efficiency, circular economy and modern slavery due diligence.


We will ensure that all employees are trained on the mandatory sustainability topics relevant to their role. Our internal training programme will continue to deliver market-leading training for our Technical Managers every month.

Social Value

We will engage our wider communities to develop a social value framework that delivers maximum community benefit. We will support apprenticeships and school leavers with their development and create a wider impact by engaging with our Approved Contractor Network.

Our Sustainability Roadmap

We’re on the road to a more sustainable future. Our Sustainability Roadmap marks the key stage gates towards achieving net-zero carbon by 2032.

Sustainability Frequently Asked Questions

Many of our customers have questions relating to our commitment to a more sustainable future.

Here you can find answers to some most frequently asked questions. If you have further questions please contact your local Technical Manager

What is carbon neutral?

Carbon Neutral refers to any carbon dioxide (CO2) released into the atmosphere from a company’s activities, which is then balanced by an equivalent amount of carbon being removed from the atmosphere. Carbon offsets can be sought to achieve this, with a minimum requirement to meet Scope 1 & 2 emissions only. Green roofs are considered effective in the reduction of atmospheric CO2 because of their ability to absorb CO2 and reduce a building’s overall energy consumption.

What is net-zero carbon?

Taking one step further than Carbon Neutral, Net-Zero Carbon also achieves a balance between the carbon emitted into the atmosphere and the carbon removed from it, but it must span across Scope 1, 2 and 3 emissions. A critical difference is that all efforts must be made to mitigate carbon across the business before offsetting the small amount remaining that is unable to be avoided.

What are the three scopes of emissions?
  • Scope 1 covers all direct emissions from owned or controlled sources. 
  • Source 2 factors the indirect emissions from the generation of purchased electricity, heating etc., consumed by the business. 
  • Scope 3 includes all other indirect emissions in a business’s supply chain.
What is operational carbon?

Operational Carbon is the amount of carbon emitted during the operational and daily use of a building. Sustainably designed roofing projects can significantly reduce operational carbon by including Green roofs and solar PV systems.

What is embodied carbon?

Embodied Carbon is the amount of carbon emitted associated with building construction, including the extraction, transportation, manufacture and installation of materials. Sustainably designed roofing projects can significantly reduce embodied carbon by including long-life systems (such as metal roof panels) that can be used for the life of a building, avoiding regular replacement and mitigating waste to landfill.

Is a metal roof system sustainable?

An R-MER metal system is manufactured from up to 55% recycled materials and is 100% recyclable at the end of its life, making it a highly sustainable roofing system.

Is a green roof system sustainable?

A Green Shield green roof system will improve air quality and provide natural habitats that encourage biodiversity. Green roofs help to keep buildings cool, reducing energy consumption and costs, making it a highly sustainable roofing system.

Are solar PV panels suitable for sustainable roofing?

A Solarise PV panel system reduces the carbon output of a building by utilising renewable solar power energy rather than other energy sources such as electricity or gas. Solar PV panels significantly reduce the operational carbon of a building, making it highly suitable for sustainable roofing.

We’re dedicated to making our Sustainability Commitment positively impact the roofing industry and ultimately, keep delivering better environments for our customers and the communities they serve.
