Aluminium pergola systems are built to be strong, modern, and long-lasting, making them a popular choice for outdoor living areas across New Zealand. With a simple and consistent maintenance routine, your pergola can continue to look great and perform well for many years.
At Undercover Industries, pergolas are custom-made in Tauranga using high-quality 6061 T6 aluminium, a material widely recognised for its strength and resistance to corrosion. Each structure is carefully prepared before being powder-coated in a Dulux colour of your choice, creating a durable and attractive finish designed to handle New Zealand’s varied weather conditions.
Although aluminium pergolas require far less maintenance than timber alternatives, a small amount of regular care will help preserve their appearance and longevity.
Why Aluminium Pergolas Are Low Maintenance
Modern aluminium pergolas are designed to handle sun, rain, and coastal environments without rusting or breaking down over time. Undercover Industries pergolas are manufactured using robust 6061 T6 aluminium, delivering long-term durability while maintaining a clean and contemporary look.
Design features such as concealed brackets and hidden fixings reduce the number of exposed joints and surfaces where dirt can gather. When combined with quality roofing options like acrylic panels, which are significantly stronger than glass while still allowing natural light through, these pergolas offer excellent durability with minimal upkeep.
Routine maintenance is simply about keeping the structure clean and protecting the finish.
General Cleaning and Care
Cleaning your pergola every three to six months is typically enough to keep it in top condition.
Use warm, soapy water along with a soft sponge or cloth to gently clean both the aluminium frame and roofing surfaces. A mild dishwashing liquid or pH-neutral cleaner works best. Avoid using harsh chemicals, abrasive brushes, or sharp tools, as these can damage the protective coatings or affect the roofing material.
Stronger cleaning products, particularly those designed to remove mould, should be avoided as they may cause long-term damage to the surface finish.
If your pergola includes outdoor blinds, it is important to retract them during strong winds to reduce strain on the system. When blinds become wet, allow them to dry fully before rolling them up to prevent moisture-related issues such as mould or discolouration.
Caring for Powder-Coated Aluminium
Powder-coated aluminium is highly durable but still benefits from regular cleaning.
Start by wiping away any loose dirt or debris using a damp cloth. Then clean the surface with warm water and a mild detergent using a soft sponge or brush. Once finished, rinse thoroughly with clean water to remove any residue.
Avoid solvents or abrasive cleaning products, as these can damage the powder-coated surface and reduce its lifespan.
Cleaning Pergola Roofing
Roofing panels should also be cleaned every few months, or more often if they are exposed to pollen, dust, or falling debris.
Warm soapy water and a soft sponge are ideal for general cleaning. For more stubborn dirt, a soft house brush can be used carefully. Avoid excessive scrubbing or abrasive tools, as these can scratch the surface.
Acrylic or polycarbonate roofing is designed to be both strong and clear, allowing light to pass through while providing protection from the elements.
Maintaining Lighting and Hardware
If your pergola includes integrated LED lighting, occasional rinsing with fresh water will help prevent the build-up of dust or salt, particularly in coastal areas.
Any stainless steel components should also be cleaned periodically using fresh water and a soft cloth. As with other parts of the pergola, avoid abrasive cleaners that could scratch or dull the finish.
Enjoying Your Pergola for the Long Term
One of the key benefits of aluminium pergola systems is how little maintenance they require compared to other materials, while still delivering excellent durability and style.
At Undercover Industries, every pergola is designed and built to suit your outdoor space, whether you are creating a sheltered patio, enhancing a deck area, or improving the connection between indoor and outdoor living. With high-quality materials, durable finishes, and thoughtful design, your pergola will continue to provide shade, shelter, and visual appeal for years to come.
