Full roof coating

Delcote 20 year Architectural Coating System

Delcote – full roof coatings system, the long established system manufactured by Delvemade is now only exclusively available from Sharmans.

  • Market leading proven performance from a trusted brand
  • Endorsed by leading steel manufacturers
  • Engineered for the roofing environment using inorganic Alkoxy technology to prevent chalking and deterioration.
  • Specified in confidence by surveyors and property managers for over 20 years
  • Industry leading 20 year system guarantee

Why Delcote?

Organic (oil-based) coatings become hard and brittle when exposed to UV and temperature changes, and over time this limits their ability to expand and contract with the sheets causing adhesion failure to the substrate.

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

Refurbishment v’s replacement

Subject to the level of roof sheet deterioration, the advantages of re coating the existing roof with the Delcote 20 year guaranteed system in lieu of oversheeting or replacing are:

  • No additional structural weight is applied
  • No risk of further penetrations
  • Delcote needs no vapour control. It’s a fully breathable membrane which can further seal the roof from air leakage, helping to retain heat
  • No disruption for building users
