EPDM (ethylene propylene diene monomer) is a sturdy membrane often used in roofs. One drawback is that EPDM tends to shrink over time, pulling on flashing installed on walls and penetrations and leaving gaps through which moisture can enter.
Routine roofing maintenance is one way to stay ahead of this issue. Read on as Universal Roofing & Exteriors shares some additional tips.
What Causes EPDM Membranes to Shrink?
Age is a factor, but it’s not the only one. Other possible causes include:
Shoddy installation – Installation errors can drastically shorten a roof’s lifespan. Installing EPDM is complicated, so there’s a higher risk of roof damage if your contractor doesn’t have enough experience. For best results, make sure to hire a qualified, experienced roofing contractor.
Faulty design – EPDM roofs have a complex design. Contractors have to take into account shrinkage and install features that can extend the roof’s lifespan. One such feature is roof drains, which help protect the EPDM membrane from wear and tear from moisture.
Manufacturer defects – The manufacturing process for EPDM membranes is sensitive. You can avoid manufacturer defects by purchasing membranes from trusted brands, like GAF®.
Why Routine Inspections Matter
Of course, no matter how durable a roof is, it will eventually experience wear and tear, which is why routine inspections are a must. That way, contractors can identify minor issues and conduct prompt roof repair before the problem worsens.
