Roof drainage refers to the system designed to remove excess water from a building's roof. This is crucial to prevent water accumulation, which can lead to structural damage, leaks, and mold growth. Roof drainage systems typically include components like gutters, downspouts, and drains that channel water away from the roof and foundation. Effective roof drainage is essential for maintaining the integrity of a building. It helps manage rainwater and snowmelt, directing it safely away from the structure. Proper installation and maintenance of gutters, downspouts, and drainage systems are vital to ensure they function correctly and protect the building from water-related issues.
