You can take the reduction for QR, but also have to increase for the slope; it's a compound DA calculation.

Here's one for Y'all. With a wet-pipe system in an attic, (4/12 pitch) can the area reduction for quick response sprinklers be used? If so, how is the ceiling height determined? From the ceiling below to the highest point of the roof?
