TypeDescriptionAdvantagesDownsidesInternal DrainageWater is directed to internal drains and pipelines that cause the structure's drainage system.- Less exposure (aesthetically pleasing)
- Better for flat roofing systems
- Effective in urban locations with restricted area- More complicated installation
- Potential for blocking and leaks inside the buildingExternal DrainageWater streams off the roof's edge into gutters and downspouts.- Simplicity of design
- Easier to maintain
- Visible for inspection and cleaning- Requires more space
- More exposed to particles
