A Midwest Perspective On The
Impact of Extreme Temperature Changes on Asphalt Shingle Roofs
In the Midwest, particularly in northwest Indiana and southwest Michigan, the transition from summer to fall brings significant and sometimes abrupt temperature changes. As summer’s extreme heat gives way to cool fall weather, the dramatic shifts, often involving temperature changes of up to 50ºF within a week, can have a profound impact on asphalt shingle roofs. For homeowners in areas like South Bend, Mishawaka, and Benton Harbor, understanding these effects is crucial to maintaining a durable and weather-resistant roof.
The Challenge of Temperature Changes
The Midwest is no stranger to extreme weather conditions, and the roofing materials used in this region must be able to withstand rapid and often severe temperature changes. Asphalt shingles, like those used by CW Roofing, are designed to be flexible and durable, but even the best materials can be challenged by the region’s unpredictable climate.
When temperatures drop suddenly after a period of intense heat, the shingles on your roof experience expansion and contraction due to the temperature changes. During the summer, shingles expand as they absorb heat. As the weather cools, they contract. This constant cycle of expansion and contraction, driven by temperature changes, can cause stress on the shingles, leading to issues such as cracking, curling, or even breaking. This problem is exacerbated when the temperature swing is significant, as is often the case in the Midwest during the fall months.
The Risks of Cold Weather
As fall progresses, temperatures in the Michiana area can fall below freezing, adding another layer of stress to your roofing system. Shingles become more brittle in cold weather, making them more susceptible to damage from the ongoing temperature changes. If your roof has already been compromised by the summer heat, the cold weather can worsen these issues, leading to leaks or further deterioration of the shingles.
The sudden onset of cold weather can also impact the adhesion of shingles. When temperatures drop too quickly, shingles may not have enough time to properly seal, which can leave your roof vulnerable to water infiltration and wind damage. In extreme cases, this can even lead to shingles lifting or blowing off entirely, further illustrating the risks posed by temperature changes.
The Benefits of CertainTeed Landmark® and Landmark PRO® Shingles
Choosing the right roofing materials is essential to mitigating the effects of extreme temperature changes. At CW Roofing, we use CertainTeed Landmark® and Landmark PRO® shingles, which are specifically designed to endure the harsh conditions of the Midwest climate.
Landmark® and Landmark PRO® Shingles are engineered with advanced durability in mind. These shingles are made with a dual-layered design that provides extra protection against cracking and splitting caused by temperature changes. The high-quality asphalt used in their construction allows them to maintain their flexibility even as temperatures fluctuate. This resilience is crucial in preventing the types of damage that can result from the extreme temperature changes common in the Midwest. To learn more about these industry-leading asphalt shingles, visit the CertainTeed website.
Additionally, CertainTeed shingles are equipped with superior granule adhesion, which helps protect the shingles from the UV rays of the summer sun and the cold, icy conditions of winter. Landmark PRO® shingles, in particular, offer enhanced protection with a thicker, more durable construction, making them an excellent choice for homeowners looking to invest in a long-lasting roofing solution capable of withstanding temperature changes.
Preparing Your Roof for Fall
As summer ends and the cooler months approach, it’s important to take proactive steps to prepare your roof for the challenges ahead, especially those related to temperature changes. Regular inspections and maintenance can help identify potential issues before they become significant problems. CW Roofing recommends scheduling a roof inspection during the fall to assess the condition of your shingles and address any areas of concern before the winter weather sets in.
The extreme temperature changes from summer to fall in the Midwest can pose significant challenges to asphalt shingle roofs. However, by choosing high-quality materials like CertainTeed Landmark® and Landmark PRO® shingles, and staying on top of regular maintenance, you can help ensure your roof remains strong and resilient against the elements. CW Roofing is here to help you protect your home with roofing solutions that are built to last, no matter what the temperature changes bring.
