To cut or not to cut ridge membrane?

[junglejim]

I’ve lapped breather membrane over the ridge and will be fitting dry fix vented ridge tiles. I’m hearing mixed opinions about whether I soups cut the felt at the ridge or not.

 

 The roof is osb Cassette with 50mm vent gap between insulation and osb… any suggestions? Layers above osb are: membrane, counter batten, tile battens, tiles

 

 Advice greatly appreciated 👍

Soups = Should 😜

yes, ridge should be open to breath. hardly ever see it done though as no one like the rain getting in before tiling.
