A commercial building’s roof can be covered with various materials, but the two most common are thermoset and thermoplastic roof membranes. At Steadfast Roofing, we aim to help you make an informed decision by comparing these two popular options for commercial roofing.
Thermoset Roof Membrane
Thermoset membranes, also known as EPDM (ethylene propylene diene monomer), are widely used for commercial buildings due to their durability and low maintenance requirements. Key features of thermoset membranes include:
- UV and Ozone Resistance: TPO membranes are engineered to resist damage from UV light and ozone, extending their lifespan and maintaining their effectiveness even under harsh environmental conditions. This resistance helps prevent deterioration and ensures the roof remains functional for years.
- Cold Flexibility: These membranes retain their flexibility in cold temperatures, ensuring that the roof remains well-insulated and effective at maintaining indoor temperatures even during the coldest months. This characteristic helps prevent issues related to brittleness and cracking.
- Reflectivity: TPO membranes are highly reflective, which enhances energy efficiency by reflecting solar heat away from the building. This property helps reduce cooling costs and improves overall energy savings by keeping indoor temperatures more stable.
- Solvent Resistance: TPO membranes are resistant to a variety of solvents, making them durable in various chemical environments. However, they have limited resistance to petroleum-based products, which may affect their performance in specific applications.
Thermoset membranes, often referred to as rubber roofs, are available in black or white and come in widths ranging from 7.5 to 50 feet with various thicknesses. Proper installation by professionals is crucial to ensure the benefits of an EPDM roof.
Thermoplastic Roof Membrane
Thermoplastic membranes, such as TPO (thermoplastic polyolefin), are another durable and reliable option for commercial roofing systems. Characteristics of thermoplastic membranes include:
- UV and Bacteria Resistance: TPO membranes offer excellent resistance to UV light and bacteria, making them particularly suitable for environments like restaurants where oils and fats are prevalent. This resistance helps maintain the membrane’s integrity and cleanliness over time.
- Color Choices: TPO membranes come in versatile color options, including black and white, to match various aesthetic preferences and functional needs. They are available in widths of 10, 12, or 20 feet, allowing for customizable installation and seamless coverage.
- Durability: When installed and maintained properly, TPO membranes are known for their longevity, with a lifespan of approximately 30 years. This durability ensures long-term performance and value, making TPO a reliable choice for commercial and residential roofing application
A significant consideration with thermoplastic membranes is the potential for leakage at the seams. Ensuring that these seams are properly welded and sealed during installation is crucial. Any gaps or improper sealing can lead to moisture infiltration, compromising the roof’s integrity and potentially leading to leaks and water damage. Proper installation techniques and regular inspections are essential to maintain a watertight seal and prevent future issues.
