What happens to asphalt if larger amounts of water are introduced during the application process?

Introducing larger amounts of water during the application process of asphalt can lead to chilling, which negatively impacts adhesion properties. Asphalt is designed to create a bond and form a waterproof barrier. When water is excessively introduced, it can cool the asphalt, causing it to harden unevenly and preventing optimal adhesion to the substrate or to additional layers of roofing material. This chilling effect compromises the overall integrity of the roof system.

The loss of adhesion due to chilling can lead to problems such as delamination or failure of the roofing system over time, as the asphalt does not properly bond to the surfaces it is intended to seal.

Understanding the impact of moisture on asphalt application is crucial for proper roofing installation to ensure durability and performance.
