Need Help With Ridge Venting Unusual Pitched Roof

I listed this post in General Discussion, but after a few responses I thought it might have a better chance listed under roofing.

I have finished framing a building that has an unusual roof and I need some ideas on how to apply a ridge vent. The roof is a gable with a shed dormer. The shed dormer ties in at the ridge allowing 2 different angles at the ridge. The roof pitch on the front of the gable is extremely steep 19/12 (58˚) and the roof pitch on the back of the gable (Shed Dormer) is about a 7/12(31˚). I have sent emails to some plastic ridge vent manufacturers (ex. ShingleVent II) and they claim their vents will go to 16/12; any higher and it will leak. Gable venting is not an option on this building. The roof will also be covered in Architectural Asphalt Shingles.

I am looking for some ideas do you have any?

might need to build a custom set of ridge vents.
I've done it.

Not exactly rocket science.

don't forget to add screening.
