Your roofing project can make a significant difference
Roofing projects provide a vital opportunity for a significant reduction in the overall carbon emissions of your building through reductions in Embodied Carbon, Operational Carbon and reductions in carbon at the End of Life phase of your roof. Our Technical Managers can help you choose the right sustainable solution for your roofing needs.
The most effective way of decreasing embodied carbon emissions is to choose a roofing system with a long lifespan, that should outlast its guarantee. Compared with shorter life products, which of course would need replacing much sooner, this greatly reduces the carbon required to produce the system. Typically, buildings are designed to last for about 60 years, so the closer you can get to achieving this the better. Additionally, where possible you should also specify a roofing system that both uses recycled materials and is itself recyclable to again reduce the embodied carbon of the system.
By conducting thorough condition reports of your existing roofing structure, it is easy to avoid unnecessarily removing the existing deck or insulation whilst conducting any refurbishment or repairs, minimising the amount of new materials needed to restore your roof, and thus reducing its carbon emissions. A moisture mapping survey in particular can help to identify very specific areas of water ingress, so that these areas can be targeted exclusively for repair.
Roof encapsulation solutions should also be seriously considered when a complete roof replacement is necessary. This allows the existing roofing structure to remain in place whilst providing a new waterproofing system This of course eliminates the need for the existing roof to go to landfill, not only saving you the disposal costs but again further reducing the embodied carbon emissions as a result.
There are a number of opportunities that your roofing solution can help to reduce the operational carbon of the whole building. Photovoltaic Solar Panels can be incorporated on your roofing system to provide renewable energy, that can be used to reduce the energy consumption of the building.
Green roofs are another very effective way of reducing the operational carbon of your building, by improving thermal efficiency, whilst also actively capturing carbon dioxide through the vegetation that it incorporates.
Finally roofing projects allow for increased insulation to be applied, which again will improve the thermal efficiency of the building, requiring less heating and cooling and thus improving the overall energy efficiency of the structure.
End of Life Carbon Reduction
The End of Life phase of the Whole Carbon Life Cycle should also be considered as it can provide more opportunities to reduce carbon emissions. It is essential to partner with both a manufacturer and approved contractors that encourage mindful waste management, mitigating the need for landfill disposal wherever possible.
It is possible to specify a roofing system that is 100% recyclable at the end of its usable life. Metal roofs, such as our R-MER range are a perfect example of this. Recycled metals produce as much as 90% less carbon when compared with metals processed from ore.
