Q&A – Fly gables and flashing

When this homeowner needed some advice on a unique fly-gable situation, they came to the AskARoofer experts.

Trevor from Kentucky was hoping to get some flashing alongside a rib on his roof, but ran into a confusing scenario. They 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 above). 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 a few thoughts on this question:

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.

About Orca Roofing

Orca Roofing & Exteriors' owners and husband-wife duo Erik Trefzger and Jessica Motais de Narbonne have experience in almost every stage of the home construction process. They’ve owned and operated Orca Homes, a to-the-studs remodeling company, since 2011 (and that’s not to mention the house-painting business Erik owned in college). After doing it all in their previous and existing businesses, the idea for Orca Roofing & Exteriors actually emerged from necessity; Erik and Jessica hired and worked with several roofers for their Orca Homes remodels, but couldn’t find one that offered the level of quality or customer service they needed. So, they made their own.
