Cold weather can wreak havoc on commercial roofing and waterproofing systems, even in regions like Texas where winters are typically mild. Property and facility managers often overlook the risks posed by rare but impactful cold snaps. Understanding how freezing temperatures, ice, and fluctuating weather conditions can damage your roof and waterproofing systems is crucial to maintaining the integrity of your building and avoiding costly repairs.
How cold weather affects commercial roofing systems
Thermal Expansion and Contraction
Temperature fluctuations during cold weather can cause roofing materials to expand and contract. This constant movement creates stress on roofing components, leading to cracks and compromised seams. Single-ply roofing material is particularly vulnerable because their large surface area amplifies these effects, potentially resulting in leaks and water damage.
Snow and Ice Accumulation
While Texas doesn’t frequently experience heavy snowfall, even a light layer of ice or snow can pose risks. Flat roofs may collect snow and ice, adding weight that strains the roof’s structural integrity. When temperatures rise, melting snow and ice can create puddles, increasing the risk of water infiltration if the roof’s drainage system is inadequate.
Freeze-Thaw Cycles
Freeze-thaw cycles occur when water seeps into small cracks in roofing materials, freezes, and expands. This expansion widens cracks and accelerates damage over time. Even brief freezes in Texas can initiate this destructive process, leaving roofs more vulnerable to subsequent rain or ice storms.

Membrane Deterioration
Waterproofing membranes are designed to protect buildings from moisture, but extreme cold can cause them to stiffen and lose flexibility. Brittle membranes are more likely to crack under pressure, compromising the system’s effectiveness.
Seam Failures
The seams of waterproofing systems are particularly susceptible to damage during cold weather. As temperatures fluctuate, seams may separate or weaken, allowing water to penetrate the building envelope. This can lead to interior damage and costly repairs.
Moisture Penetration
If waterproofing systems are compromised, water infiltration becomes a significant concern. Once moisture enters the building, it can lead to mold growth, weakened structural components, and damage to interior finishes.
Why texas property managers should be prepared
While Texas winters are generally mild, unpredictable weather patterns can bring freezing temperatures, sleet, and ice storms. These conditions, combined with heavy winter rains, can cause significant damage to unprepared roofing and waterproofing systems. Preparing for these scenarios is essential to protecting your investment and avoiding disruptions to building operations.
