Structural Risks to Commercial Buildings in Extreme Heat
Summer has just begun, and according to recent news outlets, millions of people and structures across the country are experiencing severe weather, including thunderstorms and a deadly heat wave sweeping the South.
Just as the heat takes a major toll on us, extreme weather and operational conditions affect the structural members of buildings. The most common and concerning type of structural damage occurs from roof condensation, which is caused by the rapid cooling of warmer air.
What is Roof Condensation?
Roof condensation is moisture that develops in the roof ceiling area and is trapped by foil insulation or other types of radiant barriers. If left untreated, it can destroy the entire roof structure, which can be very costly.

Risks of Roof Condensation
If left untreated, it can destroy the entire roof structure. Moisture causes rust and decay on metals, including hangers, nuts, bolts, and, in severe cases, the plywood (rooting) and plywood nails (necking) that give strength to the roof system and, in turn, hold the walls up. Damaged hangers and roof nailing need to be checked and repaired. This problem can be very costly as time goes on. In severe cases, it can turn into replacing the whole roof system.
Dangers of Roof Condensation
If untreated, roof condensation damage can be hazardous. Roof supporting members (sub-purlins, Purlins, and GLB’s) metal hangers deteriorate and can cause a failure and could fall to the floor or severely damage the roof structure.
What proactive measures can be taken…
- Underside of roof Inspections for condensation clues
- Tenant operations, changes to allow moisture to vacate the building
- Inspect and look for roof leaks, skylights, all rooftop equipment, and any penetrations through the roof membrane
Why Conduct Regular Inspections
Early detection is helpful for many reasons, one primary one being the cost factor. When detected early on, the cost to repair the damage from roof condensation is significantly less than potentially waiting until the roof hangers and roof nailing have completely deteriorated!
