Question: 1 / 400

What is the primary purpose of a roof's drainage system?

To enhance aesthetic appeal

To channel water away from the roof to prevent pooling and leaks

The main purpose of a roof's drainage system is to effectively channel water away from the roof surface, preventing issues such as water pooling, leaks, and potential structural damage. Proper drainage is crucial because if water is allowed to collect on the roof, it can lead to various problems, including increased weight on the structure, deterioration of roofing materials, and leaks that can compromise the integrity of the building.

While aesthetic appeal, structural support, and insulation are important aspects of roofing systems in general, they do not fulfill the primary function of the drainage system. The focus is on maintaining the roof's health by ensuring that water is efficiently directed away, thus preserving the roofing structure and the building as a whole.
