Gable flashing on metal tuff-rib panels

Trevor, a homeowner in Kentucky asked:

I am looking to do metal tuff-rib panels on my roof. I have a protruding fly-gable on one side of the roof (drawings attached). How do you recommend putting the gable flashing on the roof? On a standard roof, the flashing would run alongside a rib to keep water out. The fly-gable causes the rib to come down at an angle running out to the edge into the flashing.

One of our AAR experts from Orca Roofing shared:

There are a couple of options for the gable flashing, depending on your priorities:

90-degree bullnose eve style flashing: This is a simpler solution that works well if you're not concerned about water running off the leading edge of the fly-gable.

Half pan water channel flashing: This option involves a bit more work, but it effectively diverts water from the panels into the gutter, which might be preferable.

It's worth noting that standard flashing packages usually come with a standard rake flashing, so you might need to order the bullnose or half pan flashing separately.
