The Full Roof Coating

A lifetime in roofs

Our pioneering advanced metal roof coating system now comes with a 10 or 25 year manufacturers guarantee allowing Sharmans to provide stand out performance to match all your needs, wherever the roof is in its lifecycle.

This new evolution of our BBA approved Delcote system provides:

• 10 year manufacturer guarantee, single coat system simplifying application and lowering cost supporting shorter tenancy agreements and dilapidations.

• 25 year manufacturer guarantee, dual coat system to mirror the proven industry performance of the Delcote system.

With over 25 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.

Performance is guaranteed with BBA and AA fire certification, providing a metal roof coating system that is designed to extend the life and sustainability of the building.

Specified with confidence by surveyors and property managers for over 20 years.

Steel profiled roofing will last indefinitely providing the original factory applied coating is correctly maintained and re-coated as it reaches its normal expected re-paint schedule. Over time, the factory applied coatings will start to deteriorate. Re-coating the roof will extend the life and sustainability of the building.

Delcote is an inorganic coating with outstanding proven resistance to weathering from UV, rain, snow and temperature extremes to retain high movement accommodation, flexibility and adhesion without cracking, peeling or chalking.
