It is a common sight across Yorktown: a roof that looks perfectly fine from the driveway but tells a completely different story once you’re standing on it. When we looked at a local condominium complex recently, we saw exactly how deceptive a 20-year-old roof can be.

The Problem

The project featured a mix of architectural shingles and EPDM. To keep it simple, EPDM is a heavy-duty rubber membrane designed for flat surfaces where water tends to linger. Even though these materials are often sold with "lifetime" labels, our coastal climate usually has other plans. By the 20-year mark, the seals and transitions that keep your home dry are often reaching their retirement age.

The Technical Why

The most alarming discovery wasn't the shingles themselves, but the "spongy" feeling under the flat roof sections. As it turns out, moisture had been trapped beneath the rubber membrane for years. Because EPDM acts as a total vapor barrier, that trapped water had nowhere to go, so it slowly ate away at the decking—the wooden foundation of the roof. You could have looked at this roof for hours and never seen the rot; it was a hidden safety hazard waiting for someone to step on it.

Professional Advice

We want our neighbors to stay ahead of these "invisible" leaks. Here is what The Roofing Company team recommends:

  • The 20-Year Rule: Once your roof hits two decades in Virginia, it’s time for a professional set of eyes, regardless of what the warranty says.

  • Safety First: Never walk on a low-slope or flat roof if you suspect aging; soft spots can lead to a dangerous fall through the decking.

  • Mind the Gaps: Pay close attention to where your shingles meet flat roofing. These transitions are the first place the weather breaks through.

We want you to be able to sleep through a heavy downpour knowing your family is tucked away safe and dry. Watch the full Roofing for Reel series to see more behind-the-scenes projects like this one.​
