Disadvantages of EPDM Roofing for Auckland Properties

EPDM roofing, while popular for its affordability and ease of roof installation, has several drawbacks important for Auckland property owners, especially in areas like Mission Bay, to consider:

Heat Sensitivity and Damage

  • Vulnerability to High Temperatures: EPDM can shrink, stretch, or crack under extreme heat, compromising its integrity and leading to potential leaks.
  • Heat Absorption: Black EPDM roofing absorbs heat, potentially increasing cooling costs. White EPDM is available but at a higher cost.

Water-Related Issues

  • Ponding Water Susceptibility: Incorrect roof installation can lead to water accumulation, risking rot or mold, and structural damage.
  • Prone to Water Damage: EPDM roofs can suffer from damage due to water getting trapped underneath the membrane.

Aesthetic Limitations

  • Poor Aesthetic Appeal: EPDM’s rubber membrane typically has a dull, unattractive appearance, not ideal for properties where aesthetics are a priority.

Installation and Maintenance

  • Installation Cost: While the material itself is affordable, professional installation can be costly.
  • Maintenance Requirements: Regular maintenance is required to manage the risks of punctures and shrinkage.

Environmental Impact

  • Environmental Concerns: The production and disposal of EPDM can negatively impact the environment. Its energy efficiency is lower compared to other materials.

Alternatives to Consider

Mitigating the Disadvantages

  • Regular Maintenance: Frequent checks and repairs can mitigate puncture risks and shrinkage.
  • Professional Installation: Ensuring a professional installation can minimize long-term costs and maximize the roof’s lifespan.
