Restoring or cleaning your Colorbond Roof If youre thinking of restoring or cleaning your Colorbond roof, you need to know a few important things before getting started. From the technical to the cleaning and restoration advantages, it is a guide for Australians looking to make informed choices.
Why You Should Restore Colourbond Roofs
Colorbond Roofing Colorbond roofing consists of Zincalume coated high tensile steel with a baked on paint finish which is designed to perform in some of the harshest conditions. Although this multi-layering construction renders it impervious to corrosion, fading, and thermal expansion, extended periods of exposure to Australia’s harsh sun, salty breezes, and seasonal storms can naturally take its’ toll.
When is colorbond roof restoration necessary?Colorbond roofing restoration is necessary when the original paintings starts to chalking or fade, when the lichen or moss growth, and when you see signs of minor dents and surface rust patches. If these problems are ignored, they can cause early deterioration or water damage.
Restoration is a full surface rejuvenation treatment, involving cleaning your Colorbond roof, repairing any trouble spots, and recoating it. The intention is to try and prevent deterioration of the roof material and keep the roof looking and functioning as though it were new for a long time.
The Significance of the Correct Colorbond Roof Cleaning
A good colourbond roof cleaning is a necessity before any work can begin. And this is no ordinary dirt or leaves we’re fighting; the goal in such tasks is not only to remove such debris, but to prepare the surface for further treatment and make sure that sealants or paints that will be used on the surface later will adhere properly.
Pressure washing is ideal to clean Colorbond roofs, but pressure needs to be controlled. If too much pressure is used, or the nozzle angle isn’t correct, the baked-on paint layer can be scratched, or water forced under the roof sheets. It’s for this reason that pressure levels of between 1500 to 2500 PSI are recommended and that the nozzles should be wide-angle spray heads — to ensure that force is dispersed as evenly as possible.
For surfaces that have algae, mould or lichen on them – a biodegradable chemical cleaning agents can be used to dissolve organic matter without damaging or otherwise affecting the steel surface or surrounding area. Some of these treatments produce caustic fumes and should be applied at least 15 minutes if not a couple of hours before rinsing, when they are rinsed off they should be rinsed off well, and not a trace of the chemicals should remain.
Vital Steps in Re-Coating a Colorbond Roof A colorbond roof re-coating is an important procedure if your Colorbond roofing is looking a little worse for wear.
Here is an overview of what a general Colorbond roof restoration service involves: Cleaning Repairs Surface preparation Priming Re-coat Following cleaning, the surface is checked for evidence of corrosion, paint loss or sealant wear. Rusty spots are either treated with rust converters or sanded down to the bare metal and protected with anti-corrosive primer.
Primers are very crucial for surfaces already painted or ones where the topcoat has deteriorated. The primer is a bonding layer and also seals the metal from moisture. After priming, two layers of roof membrane or acrylic roof paint are applied. These liquids are formulated for metal painting and feature UV protection, color retention, and water resistance.
Depending on the nature and state of the roof, it may also involve re-tightening or replacing screws, re-sealing ridge capping, and sealing overlaps with silicone or polyurethane product in highly exposed areas to prevent water ingress.
Advantages of Restoring And Cleaning Your Colorbond Roof
One of the key benefits of having your colorbond roof cleaned and restored is that your roof’s lifespan will be largely extended. With some TLC, Colorbond roofs can last for 30+ years, and restoring your roof will help keep it structurally sound and looking its best throughout.
It is also more energy-efficient. Faded worn out coatings lets the heat in, making it hotter in the home. Newly restored roofs with reflecting coatings can bring down interior temperatures during the summer, decreasing demand for air conditioning and bills for energy use.
In terms of appearance, restoration significantly boosts curb appeal. Recoated Colorbond roofs appear almost new and can be colour matched or changed to any new age neutral. This is especially helpful if you’re planning to sell or renovate your house.
Restoration is also much more cost-effective than replacing an entire roof. Dealing with small problems early with colorbond roof cleaning and restoration can prevent large repair bills down the track.
Technical Aspects for Australia Conditions
As with all products, the Colorbond roofing in Melbourne is also subject to local weather. Take as one example, the coast, which exposes the roofs to salt air – a leading cause of corrosion (around screws, fasteners, etc.). Heavy UV exposure increases paint chalking and contributes to thermal expansion in more temperature extreme inland areas.
Current range is thermo efficient and tested for performance in Australian weather zones. To get the most bang for your buck, make sure you’re choosing roof coatings that are designed to perform under AS/NZS 2728 standards of solar reflectance and inhibit hazing in high UV and salt exposure environments.
Roof pitch is another that comes to mind. Low pitch colorbond roofs can gather more dirt and hold water in puddles, that’s why it is even significant to clean your colorbond roof properly in a regular basis.
