STAGE 1 RoofGuard® Moss Removal This treatment consists of firstly applying our proven non-corrosive self cleaning RoofGuard® Moss Removal spray treatment. The weather action combined with our treatment gently cleans the surface over a period of approximately 12 to 15 months.

STAGE 2 RoofGuard® Moss Proofing™ Once the roof has weathered sufficiently clean and been inspected by our representative the RoofGuardMoss® Proofing™ Treatment should be applied to inhibit growth. The roof will never need to be cleaned again provided this treatment is reapplied on a 2 to 3 year cycle before regrowth is apparent.

STAGE 3 (Optional) RoofGuard® Sealer As roof surfaces wear with weather action and become porous our RoofGuard®  Sealer should be applied to seal and preserve the surface against moisture penetration and help reduce heat loss.

DRY & WARM Possibly the most important reason for treating a roof is not only to keep it clean, but to keep the building dryer and warmer. The dry weight of Fibrolite can increase considerably when wet, due to water absorption on unsealed surfaces. The weight can further increase if the surface is dirty and unsealed. Apart from creating dampness in the building below, this great quantity of water in the roof is responsible for much heat loss; partly by causing the Fibrolite to lose its usually good insulating properties, but principally from the chilling effect caused by the evaporation of the water. Tests have been carried out inside roofs over the years to determine possible heat loss, from dirty sodden Fibrolite roofs compared to clean and sealed Fibrolite roofs. One test carried out in Christchurch, in cold southerly conditions, showed a difference inside roofs of more than 10 degrees colder under a wet dirty roof, as opposed to a clean sealed roof.

Edwards & Hardy use only proven, non corrosive RoofGuard^®  Treatments which have been developed over a FORTY FIVE YEAR period and have proven to be the most compatible treatments that can be applied to concrete tiles.
