Summary
When addressing extensive rainwater leaks on metal industrial roofs, using heavy-duty butyl tape is often marketed as an instant patch. However, trade specialists warn that butyl tape is designed to serve as an internal or flashing substrate layer (e.g., beneath balcony waterproofing) rather than a primary external barrier. When completely exposed to Australia's harsh UV rays and rain, it degrades rapidly, lasting only one to three years. Landlords should treat it strictly as a temporary emergency stopgap rather than a permanent roofing fix.
Key Points
Why it matters: Large roof leaks in commercial warehouses or industrial sheds cause severe rental friction. Understanding the real-world lifespan of popular quick-fix materials like butyl waterproof tape prevents long-term structural water damage.
