Freezing in winter can damage a home in numerous ways, especially the roofing. Because of the low temperatures, roof shingles can become damaged in more ways than one. Let’s look at some of the reasons why freezing temperatures can harm the shingles on a roof.
What Is the Freeze-Thaw Cycle?
One of the biggest threats to shingle integrity during the winter months is the freeze-thaw cycle — but what is the freeze-thaw cycle exactly? To put it simply, it’s a natural occurrence that takes place when the temperature drops below 32 degrees Fahrenheit, or freezing temperature, repeatedly. Water molecules expand whenever the temperature drops to form ice. However, this expansion can place pressure on shingles, resulting in cracks and damage. When the temperatures rise and fall over time, the constant expansions will place even more stress on the shingles and cause repeated damage.
Ice dams are another shingle-damaging problem that the freeze-thaw cycle can cause — but, it may also happen when there’s uneven heating from poor ventilation. After the snow melts from increased temperatures and flows down the roof as a liquid, it can become trapped behind shingles. Once it freezes again, it can cause further damage. The effects of the freeze-thaw cycle can accelerate the wear and tear of roof shingles, so be wary if you live in a climate where frequent fluctuating temperatures are a common occurrence.
Winter Weather Conditions Can Also Harm Shingles
While the freeze-thaw cycle is a major culprit of shingle damage in colder climates, the impact of winter weather conditions can also leave its mark on shingles. For example, even a little bit of snow can cause big problems, especially if the angle of your roof prevents it from falling down the sides. Additionally, excess snow can weigh down gutters, causing them to snag and allowing another point of entry for moisture along the roof line.
Even when it’s not cold enough to snow, freezing rainwater can cause problems for shingles. Should ice accumulate inside the gutters and prevent water drainage, the gutter could be torn away. Any already existing cracks in the shingles will worsen after freezing. Once temperatures rise, existing ice will melt and can seep into the interior of the structure.
It’s worth noting that harsh windstorms are also capable of harming roof shingles. Old or loose shingles can be torn off a roof and blown away entirely in the heavy winds. Also, hail storms can cause significant damage and homeowners should have their roof thoroughly inspected following any severe winter weather event.
