How Freeze-Thaw Cycles Damage Flat Roofs in West Chester — and What to Do About It
Protect Your Commercial Roof This Winter
In the southeast region of Pennsylvania, winters can be unpredictable, often shifting between several days of rainfall and freezing temperatures, including snow and ice. The frequent weather changes, particularly freeze-thaw cycles, can cause significant damage to flat commercial roofing systems, including membrane cracking and pooling. Protecting your flat commercial roof from damage this winter is easier with the help of qualified commercial roofers in West Chester, PA.
Understanding the Freeze-Thaw Cycle
When a roof is first installed, potential issues with contraction and expansion can threaten its integrity. As the roof soaks up heat during the day, roofing materials can expand, creating gaps. Then, as temperatures decrease at night, it reverses. If water gets into these gaps, it can create cracks and damage.
Warning Signs
Several warning signs that your commercial roof is damaged from extreme weather patterns can appear. These include the following:
- Leaks: Leaks may start small and then grow larger. If you spot areas of discoloration on your roof, detect mold, or smell mildew, these are common signs of a leak.
- Ice dams: These dams can form when melting snow pools in the roof's drainage system, creating a blockage and causing damage.
- Higher utility bills: Flat roofs that are damaged may lead to inefficient insulation, increasing heating costs.
Ways to Prevent Damage
Preventing damage to your flat commercial roof is possible, especially with the help of commercial roofers in West Chester, PA. One way to proactively prevent winter-weather damage is to ensure your roof's insulation is sufficient to maintain a consistent temperature.
Ensuring the roof has a good drainage system is equally important to allow water and snow to flow through and prevent ice dams from forming. Have your roof routinely inspected, before and after winter. Then, during the season, clear it of ice and snow.
