A system designed to effectively remove water from a level or near-level rooftop surface is essential for the longevity and integrity of the structure. Such systems incorporate various elements to prevent ponding, which can lead to structural damage, material degradation, and potential leaks. These systems typically involve a combination of roof slope or tapering insulation to direct water towards strategically placed drains, scuppers, or internal drainage networks.
Efficient water removal from these surfaces is critical to prevent premature roof failure. Stagnant water increases the load on the roof deck, fostering conditions conducive to algae growth and accelerating the deterioration of roofing materials. A properly implemented system mitigates these risks, extending the lifespan of the roof, reducing the need for repairs, and contributing to the overall building performance. Historically, inadequate water management has been a major cause of problems for buildings with minimal slope, emphasizing the necessity for careful design and installation.
