Are Trims Necessary?
EPDM rubber roofs have gathered a lot of traction and grown in popularity with tradesmen and DIYers due to its durability, 50 years of life expectancy and ease of installation.
One aspect of installing an EPDM rubber roof that often sparks curiosity is whether trims are required.
Trims may seem optional but they serve an important function and refine the look of an EPDM rubber roof overall.
What Are Trims?
Trims are finishing components installed along the edges of a roof. They're made from materials like UPVC or plastisol-coated steel and are designed to mechanically fit and pair with the EPDM membrane seamlessly.
Why Install Trims?
While you might be tempted to skip trims to save time or work within a budget, they do offer several major advantages.
Protecting Against Water Ingress
Trims seal the edges of the EPDM membrane, helping to prevent water from seeping underneath. Without this added protection, water infiltration can lead to leaks and compromise the roof’s structural integrity over time.
Improved Wind Resistance
Trims act as a mechanical anchor for the EPDM membrane, keeping it secure even during high winds. This is especially crucial in areas prone to storms or severe weather.
Extending Roof Lifespan
By protecting exposed edges and corners, trims reduce wear and tear on the membrane. This can help extend the life of your roofing system and reduce the chance of future repair costs.
Better Drainage
The drip trim is specifically designed to aid the flow of rainwater directly into a gutter from the roof’s surface, preventing pooling and potential water damage to the underlying structure.
The Aesthetic Factor
The Sure Edge trims were manufactured with a specific purpose in mind, to protect, extend and enhance the overall look of an EPDM roof. They hide rough-cut edges, giving the roof a clean, professional finish. This is particularly important for homes where visual appeal matters.
Is It Wise to Neglect Installing Trims?
Trims are crucial in securing an EPDM rubber roof, ensuring durability and a professional finish. A mechanical fix is always essential to secure the membrane at the edges.
Alternative Fixing Methods
Installers may use timber battens and wooden fascias to mechanically secure the membrane. Small sheds, garages or other small structures, are commonly provided with wooden fascias or battens as part of a modular pack. So, this may align with the overall construction of the building and the aesthetical appeal.
Conclusion
Installing our trims with your EPDM rubber roof isn’t solely about aesthetics, they’re a vitally important part. A mechanical fix is always required to secure the membrane and prevent wind uplift or water ingress. While timber battens and fascias are alternatives, they often demand extra materials, labour, and maintenance.
