Decragard Aftercare

After your new Decragard coating has enhanced the appearance of your roof, you will need to maintain your roof to ensure it remains looking at its very best and performs as expected.

It is a condition of the warranty issued by AHI Roofing Ltd that the following maintenance procedures are carried out after a Decragard coating is applied. Failure to carry out a regular maintenance program may result in a significantly reduced lifespan of the Decragard coating and it may also nullify the warranty.

Walking on your roof

You should not walk on your roof unless it is absolutely necessary. It is also advised to not walk on your roof if it has been raining.

If it is absolutely necessary to walk on your roof, to avoid denting, cracking or other damage to your roof you should wear soft-soled shoes, such as tennis shoes or runners.

Take your time and ensure when walking around you place your weight over the battens if you have a pressed steel tile roof. If you have a different roof surface, check with your Licensed Decragard Applicator about how to walk around before walking on the roof.

If tradespeople need to access your roof, inform them of which type of roof you have (pressed steel tile, corrugated iron, etc.) and where they should be walking on the roof. Most tradespeople will know how to walk over a roof, however they should be informed as to which precautions are required.

When working at height, ensure edge fall protection is used to prevent falls.

Moss, Algae or Lichen Growth

In the event that moss, algae or lichen growth occurs it should be removed to prevent damage to the roof surface to which a Decragard coating has been applied. 

The time and extent that the growth appears is very dependent on local conditions; this can be localised to different sections on the same roof.  The pitch, direction the roof is facing and locality of trees or any object positioned over the roof can all contribute to conditions which accelerate or inhibit moss, algae and lichen growth.

It is, however, best to clean the roof before moss, algae or lichen growth occurs as a preventative maintenance measure to ensure your refurbished Decragard coating remains looking at its very best.  Cleaning the roof will not only eliminate moss, algae and lichen growth, but also the spores that lead to them. It is suggested that roofs are cleaned every three to five years, however if you have moss, algae and lichen growth occurring you will need to clean the roof immediately.

For assistance with cleaning and removing moss/algae and lichen growth professionally and safely from your roof contact us.

Atmospheric pollutants such as dirt from building sites, fertilisers from nearby farms and gardens and pollen from trees also may lead to the contamination of roofs. These symptoms are often mistaken for algae, moss and lichen growth. Atmospheric pollutants may wash off in the heavy rain – if they don’t they need to be washed off or they may remain and contribute nutrients for moss, algae and lichen growth to occur.

Recoating/Repainting your Decragard roof

To keep your Decragard coating looking at its best, it is recommended that the roof needs to be rejuvenated again while the coating is sound and protecting your roof. This is because it provides a better surface for recoating and is more economical than waiting until the coating reaches the stage where it needs to be removed prior to application of a further coating, or other remedial work needs to be carried out.

If your roof is at the stage where it needs another refresh to ensure the life of Decragard is maximized, contact us to arrange for another free inspection and quote.
