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 concrete or clay tile roof. Unchecked these growths can;
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 is the first step in our maintenance program and will remove the moss and lichen from your roof, reduce water retention and unblock water channels.
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 every two to three years.
The RoofGuard® Moss Proofing program stops regrowth, and maintains the appearance and structural integrity of your roof, by reducing colour loss and slowing the natural deterioration of the tiles and ridging mortar.
The RoofGuard® Tile Seal product is an optional “third step” and can be applied to porous concrete and clay tiles. RoofGuard® Tile Sealer slows down the weathering process by waterproofing the tiles, which also helps to improve insulation in your home.
This treatment can only be applied after a RoofGuard® Moss Proofing treatment.
Our TileGuard® Tile Coating product is a high build coating system that consists of a dense and thick acrylic coating that provides outstanding protection and durability. TileGuard® is flexible and moves with your roof, as it expands and contracts in varying weather conditions, and has been proven, through years of natural ageing, to retain its structural integrity, colour and adhesive qualities. All of which means, a TileGuard® coated roof is very low maintenance.
Concrete tile roofs that are not regularly cleaned weather at a faster rate because moss and lichen retain surface water and secrete acids into the tiles. This damages the protective coating on the tile and can often lead to tile discolouration. In addition the tile water channels can become blocked with moss and other organic matter, which obstructs the natural flow of water down the roof and can lead to leaks.
Yes. Although nearly all property values increase over time, some of that value can be lost because of poor street appeal and the potential for higher maintenance and repair costs. RoofGuard® maintains and improves the visual appeal of your home and reduces the cost of upkeep, which helps to protect its market value.
The RoofGuard® Maintenance System is a simple three-option process that lets you choose the services you need to clean and maintain your roof. Your Edwards & Hardy RoofGuard® Representative will discuss all of the options available with you.
No, not immediately. Very little change will be apparent for the first three to six months.
The initial treatment takes about 12 months to clean your roof, with the bulk of the “cleaning” happening in the second six months of that year.
Though the moss and lichen is killed and rendered harmless by our bio-degradable solution at the time of the treatment it can take up to 12 months to “weather off”. Any chemicals that “wash” your roof more quickly are highly likely to damage your roof, cladding, spouting or garden.
Although you can request any of our services at any time, you do have to wait some 12 months for the moss and lichen removal process to finish working before undertaking a RoofGuard® Moss Proofing. However we will report on any maintenance issues at the time we Quote, or undertake the Stage 1 Moss Treatment, and we can undertake any repairs as necessary.
It is likely that your RoofGuard® treatment will be under 4% of the cost of your roof. Though the total cost will depend upon the size, pitch and overall state of your roof, it is a small amount compared to the potential cost of not treating and repairing your roof. Your Edwards & Hardy representative will be happy to discuss our costs with you, so that you have a clear understanding of the services you are paying for.
