This eave shows two distinct roof overhangs - one that is relatively short, and one that is much wider. A narrow overhang is arguably a better design to resist typical wildfire exposures as embers and flame. Wide overhangs provide protection from rain for your siding, and window and door openings on the exterior wall. This is one of several moisture versus fire “conflicting design issue” you will face when designing a building. Note also that this side of the building doesn't have a gutter. Rain water will fall off the roof, directly onto the ground.
