What is the primary purpose of waterproofing in roofing systems?

The primary purpose of waterproofing in roofing systems is to prevent the passage of water. Roofing systems are designed to protect structures from the elements, and waterproofing is a critical component in ensuring that water does not infiltrate the building. This prevention is essential for maintaining the integrity of the roof and the materials within the building, helping to avoid issues such as water damage, mold growth, and structural deterioration. Effective waterproofing contributes to the longevity of the roof and the overall health of the building by creating a barrier that keeps water out, even during heavy rainfall or snowmelt.
