The Roofing Dilemma
When choosing roofing materials, property owners often debate between polycarbonate roofing and metal roofing. Both are widely used in residential, commercial, and industrial projects—but which one offers better long-term value?
At GB PLAS, we specialize in premium polycarbonate roofing solutions engineered to outperform traditional materials like metal, delivering superior durability, insulation, and cost efficiency.
Understanding the Materials
Metal Roofing – Commonly made from steel or aluminium, metal roofing is known for its durability and strength. However, it is prone to corrosion, noise issues during rain, and heat absorption in hot climates.
Polycarbonate Roofing – A lightweight thermoplastic material, polycarbonate combines impact resistance, UV protection, and insulation. It is designed to withstand Malaysia’s tropical climate while reducing maintenance costs.
Polycarbonate vs Metal: Side-by-Side Comparison
Feature | Polycarbonate Roofing | Metal Roofing |
---|---|---|
Durability |
Excellent, impact-resistant, no rust |
Strong, but rusts over time |
Weight |
Lightweight, reduces structural load |
Heavy, needs strong support |
Weather Resistance |
High – UV and rain protection |
Medium – prone to corrosion |
Noise Level |
Quiet, even during rain |
Very noisy under rain or hail |
Thermal Insulation |
High (twin-wall/multi-wall options) |
Low, conducts heat easily |
Maintenance |
Low – minimal cleaning required |
Medium – anti-rust treatment needed |
Design Flexibility |
Clear, tinted, frosted, multiple colours |
Limited to painted finishes |
Cost Efficiency |
High – long-term savings |
Medium – higher upkeep |
Long-Term Cost Savings
While metal roofing may appear cheaper initially, polycarbonate roofing delivers better long-term savings due to:
- Reduced energy bills (thermal insulation lowers cooling costs).
- Minimal maintenance (no rust, no repainting).
- Longer lifespan in Malaysia’s tropical weather.
Conclusion: The Clear Winner
If you want a roofing solution that balances cost, performance, and design flexibility, polycarbonate roofing is the smarter investment.
