What Happens When Temperatures Change?

 In Uncategorized

As temperatures start to fall, preparation for winter begins. Everyone tends to check the basics like making sure the heater works, locating the winter coats & boots, but what about your roof? 

One of the most significant factors that contribute to roof leaks or other roof damage is extreme weather. Commercial roofs are typically built to withstand the elements, but a rapid overnight change from hot to cold or vice versa can cause damages related to thermal shock.

Thermal shock happens when air temperatures vary greatly from day to night within a single day. As temperatures rise, your building’s structure, including the roof, begins to expand. When the temperature drops, everything begins to contract. The bigger the swing in temperature, the quicker expansion and contraction will occur, resulting in various damages.

Roof leaks occur more frequently due to thermal shock. The sudden contraction and expansion can misalign or crack the sealant applied to the penetrations on the roof and create gaps in the fastenings, leaving open space for moisture to seep in. If heavy rain occurs, the roof can rapidly cool off, causing these damages and worse roof leaks.

Here are a few things you can do to lessen the likelihood of seasonal roof issues.

  1. Inspect your roof before the cold weather arrives.
  2. Ensure the leaves and fall debris is removed from the roof (Pushed away is not good enough)
  3. Make the repairs now if needed, reactive repairs are nearly double the cost than proactive repairs.
