Extreme weather changes could mean BIG problems for your roof!


October 30, 2017

We’re experiencing our typical transition from warmer temperatures into our first hard freeze. The Midwest experiences more extreme temperature shifts than most areas in the United States, and these sudden changes can wreak havoc on your roofing system. As we move into this new season, there are two particular harsh weather factors that can be damaging to your roofing system.

  • Thermal Shock—Thermal shock is what happens when air temperature varies greatly from day to night within a 24-hour period. These swings are typical for our area this time of year, when we can go from the 70’s to the low 30’s in a single day. This is very hard on a roof and can do significant damage over time. As the temperature gets warmer, the roof begins to expand—then it contracts when it gets colder. The more extreme the variation in temperature, the more extreme the expansion and contraction will be. These changes over time can take a toll on your roof: the joints crack and separate, seams tear loose, flashings will separate and the roof as a whole will deteriorate more quickly.
  • Ice—When the temperatures are dancing around freezing, as they have been lately, ice can become a major problem for Midwest roofs. When it rains on your roof, or if it snows and starts to melt, the water seeks out cracks as it flows downward. When the temperature drops overnight, the water in the cracks freezes and expands, stretching and widening the cracks. The next day the thawing process starts again and continues to deteriorate your roof.

Many factors can damage your roof and cause it to leak, and our extreme temperatures can make these factors worse. Be sure to have your roof inspected regularly to ensure that it is in proper condition. Don’t skimp on repairs or you might need full roof replacement sooner rather than later.
