How Roofing Systems Drain Water
Avoid costly water damage from your roofing system’s inability to shed rainwater. Understanding how a roof sheds rainwater will help you determine what to install or repair to prevent leaks and costly water damages. New Image Roofing Atlanta gathered information on how low-slope (flat) and steep-sloped roofing systems are engineered to shed rainwater. Low-Slope Roofing System Water Drainage Low-slope roofing systems, common in commercial and industrial buildings, present unique challenges when addressing water drainage. Unlike steep-slope roofs that allow water to naturally flow down and off the roof, low-slope roofs require a more intentional approach to prevent ponding while ensuring drainage. Note: Low-slope roofing can be EPDM , TPO , PVC , or BUR systems. Gravitational Flow and Slope Design Successful water drainage on low-slope roofing systems relies in gravitational flow. While these roofs have a slight incline, it is not as steep as in residential roofing system...
