What are Common Issues with Tpo Roofing?
In the Lower Mainland and British Columbia environments, TPO roofing systems commonly face several physical and structural challenges. The most frequent issues include:
- Seam Failures: Often caused by thermal expansion and contraction during BC’s freeze-thaw cycles, compromised seams are responsible for approximately 80% of water intrusion risks if not properly maintained.
- Punctures and Tears: The membrane can be damaged by falling branches or foot traffic during maintenance. While TPO is generally puncture-resistant, integrated reinforcement is necessary to prevent these occurrences.
- Shrinkage and Wrinkling: Over time, the material may shrink, leading to surface wrinkling that can affect the roof’s integrity.
- Ponding Water: On flat roofs with an inadequate slope, water can pool after heavy rains. If left unaddressed, this standing water leads to accelerated aging of the membrane and potential leaks.
- UV Exposure and Heat: Intense summer sunlight can eventually lead to degradation or the loss of protective granules in ballasted systems, which diminishes the roof’s energy-efficient reflective properties.
To mitigate these issues, it is recommended to conduct bi-annual inspections and ensure professional hot-air welding during the initial installation to create a monolithic, watertight barrier.
