What’s Best for My Building: EPDM Roof Repair, Replacement, or Restoration?

Need a surefire way to find out how many years your membrane has until retirement? It’s easier than you might think. Here’s five steps that can help:

1. Check for Leaks & Blistering: Leaks are often indicative of underlying problems with the membrane. If you notice any water stains on the roof surface, your ceiling, or upper walls then this could be an indication that it’s time for further preventive actions. On the other hand, blistering, also known as “bubbling,”occurs when there’s a separation between your EPDM membrane and the substrate. A variety of factors can cause this from improper installation or to old age..
2. Keep Your Eye Out for Sun Damage: While they are more durable than their shingle counterparts, EPDM roofing systems are still susceptible to sun damage cracking and splitting the membrane. That’s why you need to look for any signs of sun damage, like:
   • Discoloration: A yellowing of the membrane, typically.
   • Fading: Darker-colored membranes losing their original shade or shine.
   • Cracks: Thin, often linear openings in the rubber caused by aging, UV exposure, or physical stress.
   • Splits: Larger separations in the roofing material, usually along seams, punctures, or other weak points.
3. If You See Rust, Find a Contractor You Trust: Rust on nails, fasteners, or staples indicates that moisture has gotten through the membrane and caused corrosion on the underlying metal components of the roof system. Fasteners provide secure attachment points for the membrane and sealant, but they become damaged over time. That’s why it’s essential to ensure that they are not corroded or broken, as this could lead to leaks and other serious problems.
4. Schedule a Professional Assessment: Whether you can get by with a simple EPDM roof patch, or your membrane approaching its last days, professional inspections save you time, money, and hassle in the long-run.
