Why Freeze/Thaw Cycles Matter for Your Commercial Roof

Winter in Ohio (and the Midwest) doesn’t always stay consistently cold.  Temperatures can bounce above and below freezing through late winter and early spring. These freeze/thaw cycles can create stress on commercial roofing systems that many property managers don’t realize is happening.

What Are Freeze/Thaw Cycles?

When snow or ice melts during a warmer day and then refreezes overnight, water that collected on the roof expands as it turns back into ice. Over repeated cycles, this expansion and contraction stresses roofing materials and can accelerate wear.

Why Commercial Roofs Are Especially Vulnerable

Flat and low-slope roofs are more prone to water ponding because they lack steep slopes that shed water quickly. When meltwater remains on the surface and freezes again, it stresses seams and fasteners and can widen existing cracks.

What often starts as microscopic damage can grow larger over time. Small splits in the membrane or weakened flashing aren’t always obvious from the ground, but when water infiltrates insulation or the roof deck during a thaw, interior leaks and structural damage can follow.

The Smart Move? Proactive Inspection

Now, during the transition between winter and spring, is an ideal time to have your roof inspected. Identifying subtle stress or ponding issues early can help you avoid expensive repairs later in the season.
