Polycarbonate Roofing Maintenance Made Easy – The Basics

Prized for its lightweight and robust qualities, polycarbonate roofing has emerged as a top choice for both residential and commercial buildings. With its incredible insulation and UV protection, it’s the go-to option for patios, greenhouses, and skylights. However, like any roofing material, it demands regular maintenance to maximise its lifespan.

The Allure of Polycarbonate

Polycarbonate-based roofing stands out for its strength and versatility. It offers various types, including twin-wall, multi-wall, and corrugated sheets, suitable for diverse applications.

Not only is it impact-resistant, but it also provides exceptional insulation, making it perfect for areas where temperature control is crucial. However, these advantages are only assured with consistent maintenance.

Common Polycarbonate Issues

Neglecting your polycarbonate roof can lead to a range of problems. Over time, exposure to the elements can cause discolouration. Scratches from falling debris or incorrect cleaning techniques can mar its appearance. Worst of all, improper installation and maintenance can result in leaks, turning your dry space into a waterlogged disaster.

Vital Polycarbonate Maintenance Tips

  1. Regular Cleaning: Use a soft cloth, mild detergent, and warm water for cleaning. Avoid abrasive materials to prevent scratches. Routine cleaning keeps your roofing materials free of dirt and grime.
  2. Inspecting for Damage: Periodically check for cracks, scratches, or loose fasteners. Address these promptly to prevent further damage. A bi-annual inspection is advisable.
  3. Repairing Scratches and Cracks: Minor scratches can be buffed out with a fine abrasive, followed by gentle buffing with a clean cloth. For larger cracks, consult a professional. Timely repairs ensure the roof’s structural integrity.
  4. UV Protection: Invest in UV-resistant coatings to extend the life of your polycarbonate roof. These coatings shield the material from harmful UV rays that can degrade it over time.

A Comprehensive Maintenance Checklist

To maintain your polycarbonate roof, follow these steps:

  • Regularly clean the surface with a mild detergent.
  • Inspect for damage every six months.
  • Repair minor scratches using an abrasive.
  • Apply UV protection as needed, especially in sunny regions.
  • Before winter, check for debris and clear it to prevent snow buildup.

When to Seek Professional Help

Some issues call for professional intervention. If you notice extensive damage, leaks, or significant discolouration, it’s time to engage a roofing contractor. When seeking professional help, ensure you choose a reliable and experienced expert.


Maintaining your polycarbonate roofing may seem like a chore, but it’s an investment in the durability and functionality of your structure. So, embrace these straightforward maintenance tips to ensure your roof continues to shine under the sun.
