Freeze Damage Roof Repair for Columbus Commercial Buildings

The January 2014 polar vortex brought five consecutive days of sub-zero temperatures to central Ohio — the longest sustained below-zero period in Columbus's recorded weather history. It froze internal roof drains solid, cracked pipe boots across thousands of commercial roofs, and separated membrane flashings that had been marginal for years. Freeze damage on Columbus commercial roofs is distinct from general ice and snow damage.

The 2014 polar vortex was a defining event for commercial roof performance in central Ohio. Sustained temperatures of -10°F to -15°F for 72 to 96 hours did something that normal Columbus winters do not do: they froze internal roof drain bodies solid from below. When drains freeze from the inside — not from the surface — the ice expansion cracks the cast iron or plastic drain body itself, destroys the clamping ring seal, and renders the drain non-functional. After the 2014 event, we assessed commercial roofs across Franklin County where frozen drain bodies had been cracked and the subsequent melt sent water through the cracked drain housing into the roof assembly.

What gets verified on the roof

How the Columbus property context affects the scope

What ownership receives

The outcome is documentation owners can use to decide whether repair, replacement, temporary stabilization, or claim support is the right next move.

Freeze Damage Roof Repair for Columbus Commercial Buildings questions

My Columbus commercial building had frozen drains after the 2014 polar vortex — how do I prevent it from happening again?

Internal roof drain freeze prevention uses one or two approaches: heat tape installed in the drain bowl and top section of the leader pipe, or an oversized drain body specification that reduces the internal water volume available to freeze. We install heat tape in drains identified as freeze risks based on their configuration — drains on north-facing roof sections with cold-air exposure from below are at highest risk. Heat tape is a low-cost installation compared to the cost of drain body replacement.

How do freeze damage repairs get handled by commercial property insurance?

Freeze damage is covered under the standard commercial property policy as a named peril in most Ohio policies. The 2014 polar vortex produced a significant volume of commercial insurance claims in central Ohio, and adjusters in the Columbus market are familiar with freeze-specific damage. We document freeze damage per the same methodology as other storm damage — photo log, measured scope, material takeoffs — and the documentation supports the claim process.
