How do I maintain my Colorbond roof?

The following guide is from the Colorbond web site. All credit goes to the author of this article.

Simple maintenance of COLORBOND® steel and ZINCALUME® steel by regular washing with water, will not only enhance its life but maintain its attractiveness for longer periods thus protecting your asset. Applications where the paint finish is automatically washed by rainwater do not usually require this maintenance, e.g. roof cladding. Examples of applications requiring maintenance cleaning include wall cladding under eaves, garage doors and the underside of eave gutters.

Areas not regularly washed by rainwater should be hosed down at least every six months and more frequently in coastal areas where marine salt spray is prevalent, and in areas where high levels of industrial fallout occur.

In cases where the regular maintenance referred to above does not remove all dirt which may have adhered to the surface of the paint, the following procedure should be carried out:

  • Wash the surface with a mild solution of pure soap or mild non-abrasive kitchen detergent in warm water.
  • Application should be with a sponge, soft cloth or soft bristle nylon brush, and should be gentle to prevent shiny spots.
  • The COLORBOND® steel and ZINCALUME® steel should be thoroughly rinsed with clean water immediately after cleaning to remove traces of detergent.

Never use abrasive or solvent type cleaners (turps, petrol,kerosene, paint thinners) on COLORBOND® steel and ZINCALUME® steel.

If cared for in accordance with these instructions, your building components made from COLORBOND® prepainted steel and ZINCALUME® steel will give many years of low maintenance life.
