​​Carbon reduction with Sharmans metal roof refurbishment systems

A staggering 28% of the greenhouse gases produced worldwide come from the energy used to power, heat and cool buildings. Facing the real possibility of a global emergency, changes need to be made to conserve and protect the environment.

With sustainability high on the agenda, tenants and landlords are now turning to solar power to cut emissions and greenhouse gases. Solar PV panel systems also have the potential for payback in as little as 7-8 years due to the rising cost of energy, which is a great incentive to make the switch.

Prior to the commencement of any commercial solar PV installation, you should consider the condition of your metal roof. It is crucial that the remaining life cycle of the roof aligns with the expected life cycle of the solar PV system. A decision would need to be made regarding the replacement, repair or refurbishment of the roof after 10 years of its lifecycle.

Refurbishment with the correct products is the most sustainable option due to the amount of embodied carbon that can be saved. Did you know that refurbishing a metal roof using Sharmans roof refurbishment systems incurs 5x less embodied carbon than a standard roof replacement?

Whilst replacing the roof may make your building more energy efficient, there are a number of other factors for you to consider. Raw materials must be sustainably sourced, manufactured and shipped to the site, all of which add to the project’s carbon footprint.

This would also apply to the oversheeting process, as it requires the use of new metal and does not provide any protection against the life cycle. Your roof will still go through the process of breakdown which in turn results in more disruption, additional cost and potentially adds to the carbon footprint rather than reducing it.

Patch repairs are generally not the most effective or sustainable way to bring the roof back up to standard. They may seem appealing in the form of minimal cost and low disruption, but there is the possibility of recurring issues with the roof, leading to future upheaval.

Choosing roof refurbishment over repair or replacement offers the same guaranteed lifespan, but at a fraction of the cost. Not to mention the environmental benefits it carries as no new metal is required, significantly reducing the amount of embodied carbon produced.

The best option for refurbishing metal roof sheets is applying silicone coating products. These products address the issues of metal roof fabric degradation and cut edge corrosion, therefore extending the life cycle of your metal roof by up to 25 years.
