How Do Blue Roof Programs Perform?
Blue roof systems use very carefully built drainage components to manage the motion of rainwater. Instead of making it possible for h2o to depart the roof instantly, circulation Command outlets restrict the discharge charge, developing momentary storage across the roof surface area.
After rainfall has lessened, the saved water little by little drains away from the managed stores until the roof returns to its here regular problem.
