Understanding Shingle Roof Behavior: The Importance of Heat in Achieving Flattened Shingles

Updated: Jun 9

Introduction: As residents of Brevard County, Florida, we understand the importance of a sturdy and reliable roof, especially in the face of the unpredictable weather conditions we often experience. However, have you ever noticed that newly installed shingles may not lay flat initially, causing concern for homeowners? Fear not, for this phenomenon is perfectly normal and is a result of the shingles needing time to adjust to their surroundings and temperature. In this article, we delve into the science behind why shingles may not lay flat until they heat up, providing valuable insights into the roofing process.

Understanding Shingle Behavior: When shingles are first installed, they may appear to be slightly curled or not lying completely flat. This occurrence is not a cause for alarm but rather a natural part of the roofing process. Shingle manufacturers, such as GAF, advise that shingles need time to acclimate to their environment and temperature before they can lay flat. Cold air application during installation can temporarily cause shingles to appear as though they are not laying down properly. However, it's essential to note that this is normal and does not indicate any defect in the roofing materials. Please refer to the GAF website for further information

Manufacturer Guidelines and Warranty Protection: To ensure the longevity and effectiveness of your roofing system, it is crucial to adhere to the manufacturer's guidelines provided by reputable companies like GAF. According to GAF's recommendations, allowing the shingles to heat up naturally will facilitate the flattening process. It's important not to rush this process or attempt to manually adjust the shingles, as this could potentially damage the roofing material and void the warranty. Patience is key, and allowing the shingles to settle and flatten on their own will ultimately lead to a more durable and aesthetically pleasing roof.

Conclusion: In conclusion, the temporary curling or lack of flatness in newly installed shingles is a normal occurrence that should not cause concern for homeowners. By understanding the science behind shingle behavior and following manufacturer guidelines, such as those provided by GAF, you can ensure the integrity of your roofing system and protect your investment. Remember, patience is paramount, and allowing the shingles to naturally heat up and lay flat will result in a robust and visually appealing roof that will withstand the test of time.
