When it comes to hose valves and standpipe requirements, always verify with the AHJ to find out what they want.

The stated intent of the rooftop connection(s) is to enable forward flow testing of the system. However – and this goes to my mantra of many years now – it is incumbent on the designer to verify with the serving FD is they require roof connections that they may use for firefighting. I have been made aware of several fire incidents that used roof connection hose streams and I am also aware of fireground strategies that encompass these connections. The foregoing is my opinion only and does not represent NFPA or the NFPA 14 Technical Committee, nor intended to serve as an interpretation of the standard. Steve L.

The requirement for installing a hose valve is driven by the stairway requirements found in the building code which requires at least one stairway providing access to the roof. If the stairway extends to the roof, then a hose valve is required at the top landing or on the roof. If there is no roof access from the stairway, then no hose valve is required. The fire service will use the hose valve where they have safe access from the stairway but they will not walk across the roof dragging fire hose to hook up to a hose valve located where no safe access was provided.
