Delcote® Architectural Full Roof Coating

Delamination and deterioration

Steel profiled roofing will last indefinitely, provided the original factory applied coating is correctly maintained. Over time, these coatings will undergo the challenges of delamination and deterioration, threatening the roof’s structure and performance. Protecting your roof with a roof refurbishment system will extend the life cycle of a building.

Roof refurbishment systems are a cost effective and sustainable solution for those who want to reduce their environmental impact while ensuring the longevity of their roof. Choosing refurbishment over a replacement will eliminate the need for new materials and will cause less disruption to the main building, mitigating carbon emissions and contributing to sustainability.

A lifetime of roofs

Our market leading metal roof coating system offers a product guarantee that can last up to 10 or 25 years, allowing Sharmans to provide stand out performance to match all your needs, wherever the roof is in its life cycle.

Designed to help prevent leaks and extend the lifespan of commercial metal roofs and with over 35 years of proven performance, the durable Delcote® roof coating system continues to lead the way when it comes to the ongoing demands of modern pitched metal roofs.

Delcote® is an inorganic coating with an outstanding proven resistance to weathering from UV, rain, snow and temperature extremes. It retains high movement accommodation, flexibility and adhesion without compromise.
