What is the importance of a roof's drainage system?

A roof's drainage system plays a crucial role in protecting the integrity of the building. Effective water management is essential to prevent water accumulation on the roof, which can lead to various problems such as leaks, structural damage, and the potential for mold growth inside the building. By channeling water away from the roof and away from the foundation, the drainage system helps to maintain the roof's performance and longevity.

When water is not properly drained, it can create excessive weight, cause deterioration of roofing materials, and lead to significant repair costs. Additionally, if water pools on the roof, it may eventually seep through any breaches in the roofing system, allowing moisture to enter the building. Therefore, the primary function of a roof's drainage system is to ensure that water is effectively channeled away, safeguarding both the roof and the overall structure from potential water damage.
