EPDM rubber roofing
Bonded rubber membrane
The parapet is where more commercial leaks originate than anywhere except seams. The membrane turns up the wall, is terminated mechanically, and is capped — and every one of those three can fail independently. Coping joints open, counter-flashing pulls out of its reglet, and the termination bar loosens as the building moves. Water entering here often tracks a considerable distance before showing inside, which is why parapet leaks are frequently misdiagnosed.
Berrien County sits far enough south to take the inland remnants of Gulf and Atlantic tropical systems, and on a low-slope roof that matters differently than it does on a pitched one. Sustained wind drives rain horizontally against upstands and parapets for hours, finding terminations and counter-flashing that shed vertical water perfectly well. The heat does the slower damage: roofs across Berrien County run hot for most of the year, which ages membrane, hardens seam adhesive and works every detail loose through thermal cycling. Then the humidity means that once water is inside the build-up it does not leave — saturated insulation in this climate stays saturated, quietly adding load and destroying thermal performance long before anyone reports a leak. That is why a moisture survey here tells you more about a roof's remaining life than its age does.
Routinely. Water entering at a parapet runs between membrane and insulation, or along the deck, and surfaces at the first penetration or low point it reaches. Parapet leaks presenting in the middle of a tenant space are very common and very often misdiagnosed.
Sealant buys a year or two at most on a joint that moves with the building. Where a coping is the entry point, the durable fix is a proper cover plate or a redesigned joint — sealant alone is a maintenance commitment, not a repair.
