Market Leading Roof and Gutter Refurbishment Systems

Sharmans roof and gutter refurbishment systems are engineered to prevent leaks and extend building life cycles. Installed in the commercial roof sector since 1985, our market leading systems are guaranteed for up to 25 years, providing complete peace of mind to Surveyors, Facilities Managers, Property Managers and Contractors.



The age-old debate between replacing, repairing and refurbishing stands stronger than ever in the roofing industry. However, refurbishment with the correct products is the most sustainable option due to the amount of embodied carbon that can be saved.

Refurbishing a metal roof using Sharmans roof refurbishment systems incurs 5x less embodied carbon than a standard roof replacement. And choosing roof refurbishment over a replacement offers the same guaranteed life span, but at a fraction of the cost.

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 a metal roof by up to 25 years.
