Self-Repair – How MagnaFlow™ Works

MagnaFlow™ is a major breakthrough in modern roofing, featuring a range of practical benefits and applications:

  • MagnaFlow™ products are designed to self-repair.
  • Microscopic amounts of magnesium flow into scratches and form a seal over the damaged area.
  • This seal means the roof is protected from water, oxygen and other sources of corrosion.
  • The name MagnaFlow™ is derived from the products ability to flow and repair itself.

The self-repairing characteristics of MagnaFlow™ also prevent the spread of corrosion in roofing. This maintains the integrity of the roofing panels and reduces maintenance and replacement costs.
