Longrun and Painted Metal Tiles Roofs
With over 55 years’ experience in keeping New Zealand roofs clean, the Edwards & Hardy RoofGuard® product offers unparalleled expertise in the removal of Moss, Mould and Lichen from your roof.
Left unattended, moss, mould and lichen can severely damage your Longrun or Painted Metal Tile roof. Unchecked these growths can;
- Void the Manufacturer’s Warranty
- Cause permanent etching to the coating and substrate
- Cause corrosion
- Decrease the life of the roof
Edwards & Hardy Roofing uses industry leading, environmental friendly, bio-degradable solutions, and a robust two stage process, to remove all growths and keep your roof looking great and performing at its best.
RoofGuard® Moss and Grime Removal
RoofGuard® Moss and Grime Removal is the first step in our maintenance program and will remove the moss and lichen from your roof. If not removed the moss and lichen will eventually damage the protective coating on your roof and compromise the structural integrity of your roof.
RoofGuard® Moss Proofing
After your roof has been weathered clean, which takes around 12 months, we will undertake a RoofGuard® Moss Proofing treatment, which we recommend you continue to apply periodically. The RoofGuard® Moss Proofing program stops regrowth, and maintains the appearance and structural integrity of your roof, by keeping it free of the cumulative corrosion effects caused by moss, mould, dirt and debris. The RoofGuard® Moss Proofing program is also recommended on new roofs, and roofs that have been recently recoated, in order to maintain the Manufacturer and Supplier Warranties. In most circumstances, for your new roof warranty to be valid, all organic growth such as moss, mould and lichen should be removed to prevent damage to your roof’s protective coating.
