The Winter Weather Challenge for Commercial Roofs
As winter approaches, the forecasts from the National Oceanic and Atmospheric Administration (NOAA) indicate that many areas, especially in the northern tier of the continental U.S., will likely experience wetter-than-average conditions. This is particularly crucial for commercial property owners and roofing contractors alike, as winter weather can pose significant threats to roof integrity.
Understanding the Freeze-Thaw Cycle
The freeze-thaw cycle is one of the primary adversaries that roofs face during winter. Water can seep into cracks in the roof membrane, and when temperatures drop, this water freezes and expands. This expansion can lead to further cracks or openings, allowing more water to enter the roof system. As a result, the repeated cycles of freezing and thawing can weaken the materials, making them more brittle and prone to leaks.
Winter Hazards That Impact Roofs
In addition to freeze-thaw cycles, several other winter hazards threaten commercial roofs. For instance, inadequate insulation and poor ventilation can lead to condensation, which, if not addressed, may cause mold and significant internal damage. High winds can tear away flashings, which are crucial for sealing joints and edges, while accumulated snow can create excessive weight that risks roof collapse. Professional snow removal is essential to mitigate these risks safely.
Take Action Now to Protect Your Roof
Property owners should be proactive in winterizing their roofs. Regular inspections and maintenance can go a long way in preventing costly repairs. Consult with local roofing specialists in London to schedule comprehensive roof assessments and repairs that align with winter preparedness.
