The Allure of Polycarbonate Roofing
Polycarbonate roofing has become a popular choice in Bali, often seen in carports and patios. Its lightweight and modern appearance makes it an attractive option for many. It’s often marketed as a quick and easy solution for providing cover. However, beneath the surface lies a series of challenges that can lead to ongoing headaches for homeowners.
The Leaky Reality
One of the most common complaints with polycarbonate roofs is their tendency to leak. Despite initial appearances, these roofs can become a source of constant frustration. Here’s why:
- Improper Installation: The material is often installed by tradesmen who are not familiar with its specific requirements. This can result in leaks that are difficult to resolve.
- Screws and Compression: When screws are tightened too much, they compress the plastic, creating depressions where water can pool and seep through the screw holes.
- Cracking: Exposure to the Balinese sun can cause the plastic to crack, allowing water to penetrate through the flutes of the polycarbonate sheets.
- Silicone Misuse: Many attempt to fix leaks with silicone, which often fails to adhere properly to polycarbonate. This leads to a cycle of temporary fixes that never resolve the root issue.
The Polycarbonate System
It’s important to note that polycarbonate roofing is designed to be installed as part of a system. This system includes:
- Aluminium Joining Channels: Specially designed channels that connect the plastic sheets without the need for screws or nails going through the plastic.
- Rubber Sealing Strips: These strips create a watertight seal when used with the aluminium channels.
The Problem in Bali: Often, only the polycarbonate sheeting is used, and tradesmen on the island will use screws and silicone to install the plastic. The proper channels and rubber sealing strips are often unavailable locally. This method may seem like a cost-effective solution but typically leads to problems that require more spending and maintenance over time.
Better Alternatives for Lasting Results
When it comes to roofing in Bali, it’s important to consider the long-term performance of materials. Instead of struggling with the issues of polycarbonate, consider these alternatives:
- Strengthened Glass: For a premium, high-quality look that offers durability and weather resistance, strengthened glass is an excellent option.
- Chladian: For more budget-conscious projects like carports, Chladian is a durable plastic that is suitable as an alternative.
Key Installation Tips for Any Roof:
- Proper Slope: Ensure adequate slope to allow rainwater to drain effectively.
- Sufficient Overlap: Always ensure sufficient overlap when installing panels.
- Slightly Larger Bolt Holes: When using bolts, drill holes slightly larger than the bolt size, allowing for expansion and contraction of the plastic.
- Rubber Seals: Always use rubber seals under bolt heads to prevent water ingress.
- Avoid Over-Tightening: Do not over-tighten bolts. This can damage the material and lead to leaks.
Conclusion
While polycarbonate roofing may seem like a quick and easy fix, it often leads to ongoing problems in Bali’s climate. Understanding the correct installation methods and considering alternatives like strengthened glass or Chladian can help ensure that your roofs remain leak-free and durable for years to come. By making smart choices when it comes to roofing, you can avoid costly repairs and headaches down the road.
