Roof collection
Closed roof elements direct water toward gutters or channels built into the system.

Where Does Rainwater Go on an Outdoor Roof System?
Integrated drainage only solves the first part of the water path. The project also needs to know where collected water leaves the roof and what happens when it reaches the site.
Planning guidance — final supplied configuration remains project-specific.
Structure discharge
Water may travel through beams, gutters or posts depending on the system configuration.
Site connection
The local project team should confirm discharge, stormwater connection, overflow behaviour and surrounding levels so concentrated water does not create a new problem.
