Rain reduction factor for roofs

Post by WUFImem » Tue Aug 05, 2014 7:47 pm -1100

I have a pitched roof with slates. The slates, ventilated air cavity and batten are not simulated. The outer boundary of the simulation is the vapor tight underroof layer.

Which rain reduction factor should be used in this roof?

Switch of the rain (0) as you start at the weathering barrier and there is no direct rain in reality.
