Understanding Installation Considerations

Coastal Environments

The Galvalume roof is bad for areas directly exposed to saltwater spray. Saltwater contains high concentrations of chlorides. Galvalume can accelerate corrosion of the aluminium-zinc alloy coating on galvalume. Alternative metal roofing materials for aluminum are better suited as they naturally form a protective oxide layer. This helps resist corrosion from saltwater.

Highly Corrosive Environments

You can use Galvalume in areas with high concentrations of chemicals, animal confinement spaces, or exposure to industrial fallout. Ammonia, Agricultural chemicals, and acidic rain can degrade the aluminium-zinc coating over time. In these environments, you can opt for corrosion-resistant galvalume roofing materials. With a special pre-painted finish designed for such conditions – this may be more suitable.

Aesthetics and Maintenance

  • Initial Brightness: You can be aware that a new Galvalume roof can appear quite bright. Especially in sunlight, this is the point where you might feel a tad bit of irritation. This brightness will naturally weather and dull over time.   
  • Scuffing Potential: Bare Galvalume is susceptible to scuffing during installation. Especially in high-traffic areas, you can plan carefully and implement techniques that are crucial to minimize this risk.
