Blue roof. Green roof. One controller.
SmartFlow connects to any existing irrigation controller to use retained rainwater for rooftop vegetation. No full green roof installation required. Works on any existing flat roof today.
Green roofs are expensive to install from scratch
Full green roof systems require structural reinforcement, specialist substrate, and significant upfront investment. Most smart drainage competitors (Optigrün, Sempergreen) require a full green roof installation before adding smart drainage. SmartFlow works the other way: it delivers flood control on any existing flat roof, and then adds green integration as a software-controlled option using your existing irrigation infrastructure.
Three upgrade paths from any flat roof
Choose the path that fits your building today. You can upgrade later without replacing hardware.
- Blue roof only — flood control + real-time monitoring
- Blue-green roof — flood control + irrigation integration (retained rainwater feeds rooftop vegetation)
- Portfolio — coordinate multiple buildings from one dashboard
Two active blue-green installations available as references on request.
Three upgrade paths
Blue Roof Only
Full flood control and real-time monitoring. SmartFlow Core installed on existing drain outlets. Compliance reports generated automatically every storm.
Blue-Green Roof
Adds irrigation integration to the Blue Roof. SmartFlow connects to your existing irrigation controller to feed stored rainwater to rooftop vegetation — turning flood retention into a water resource.
Portfolio Blue-Green
Coordinate flood control and irrigation across multiple buildings from a single dashboard. Shared compliance reporting and coordinated storm response.
