In my opinion, that would mean a straight up discharge would need to be terminated 8' above the roof.

Many pressure reducing valves have vents that require to only breath with atmosphere. In this case, a screen will do.
If the vent is for an internal relief of product,then local codes would prevail for the product being released.

Your question:

Did not give us proper data needed to give a proper answer.
Example:
- Is the state of the commodity being released a Fluid or gas?
- Is the commodity a hydrocarbon or a toxic chemical
- What is the temperature of the release?
- What is the country where this project is located?
- Roof of what kind of building?
