Moisture control is essential in roofing systems primarily because it prevents damage to roofing components. When moisture infiltrates a roofing assembly, it can lead to a variety of issues such as the deterioration of roof materials, rust and corrosion of metal components, and the growth of mold and mildew. These problems can compromise the structural integrity of the roof, resulting in leaks and failures that may necessitate costly repairs or even complete replacement.

Maintaining an effective moisture control strategy helps ensure the longevity and performance of the roofing system. This entails managing water that can enter the roofing system, whether through leaks, condensation, or inadequate drainage. By effectively controlling moisture, the risk of structural damage is alleviated, ultimately preserving the roof’s functionality and extending its lifespan.
