A metal roof or flat roof at the end of its coating life does not necessarily need to be replaced. Professional on-site roof coating — applying a new protective coating over the existing substrate — can extend roof life significantly at a fraction of replacement cost.

Types of Roof We Coat

Profiled steel roofing — corrugated and trapezoidal steel roof sheets. Cleaned, treated for any corrosion, and overcoated with a high-performance protective coating.
Standing seam metal roofing — aluminium and zinc standing seam roofs. Protective coating to extend life and prevent surface oxidation.
Flat roofs — EPDM, GRP and asphalt flat roofs. Coating systems to seal and protect ageing flat roof surfaces.
Box profile cladding — combined roof and wall cladding systems on industrial and commercial buildings.

Cut Edge Corrosion on Steel Roofs

Cut edge corrosion — where the cut edges of profiled steel roof sheets rust — is one of the most common problems on industrial and agricultural buildings. We carry out specialist cut edge corrosion treatment including surface preparation, rust treatment and edge sealing before applying a full roof coating.

How Much Does Roof Coating Cost?

Roof coating typically costs 10–20% of full roof replacement. The exact cost depends on the roof area, access requirements and the condition of the existing surface. Contact us for a site-specific quotation.
