Benefits of EPDM for Metal & Concrete Roofs

EPDM (Ethylene Propylene Diene Monomer) offers significant benefits when applied to metal roofs, primarily by providing superior waterproofing, enhancing durability against weather extremes, and offering a cost-effective restoration alternative to full replacement

Enhanced Durability and Weather Resistance

Waterproofing: EPDM creates an impenetrable and virtually leak-proof barrier, an essential benefit as metal roofs can be prone to leaks at seams and fasteners.

Flexibility: The synthetic rubber material is highly flexible and can elongate over 300%, allowing it to adapt to the natural expansion and contraction of the underlying metal roof due to temperature fluctuations without cracking or losing integrity.

Resistance to Elements: EPDM is highly resistant to UV radiation, ozone, wind, and hail, which helps protect the metal from sun damage and environmental stresses that cause degradation over time.

Corrosion Protection: EPDM coatings often contain a rust inhibitor, which helps to prevent corrosion on the metal substrate, significantly extending the life of the entire roofing system.

Cost-Effectiveness and Maintenance

Longevity: An EPDM system or coating can add decades of life to an existing metal roof, with some EPDM roofs lasting 50 years or more with proper maintenance.

Low Maintenance: Once installed, EPDM requires minimal upkeep, usually only needing periodic inspections and cleaning.

Easy Repair: If minor damage or punctures occur, repairs are typically simple, fast, and inexpensive, often involving only a patch and adhesive.

Restoration Option: Applying an EPDM membrane or a liquid EPDM coating is a cost-effective alternative to a full metal roof replacement, saving significantly on material and labor costs.

Energy Efficiency and Environmental Benefits

Thermal Regulation: EPDM offers natural insulating properties. Black EPDM retains heat in cooler climates, while white EPDM options reflect sunlight, reducing heat absorption and lowering air conditioning costs in warmer regions.

Eco-Friendliness: EPDM is an inert material that is often made from recycled content and is 100% recyclable at the end of its long life, making it an environmentally friendly option.
