Vapor Barrier
A vapor barrier is an important protective layer used in roofing and construction that stops moisture from getting into buildings. Think of it like a shield that keeps water vapor from damaging insulation and other building materials. Roofers install these barriers to prevent problems like mold, rot, and reduced insulation effectiveness. Similar products include moisture barriers and vapor retarders. This is a critical component in modern construction that helps buildings stay dry and energy-efficient.
