Corrugated Metal Roof - how did you ventilate your panels

[Cpd]

 As your venting above the insulation and I assume above the ply I don’t think you need to worry about venting the ridge. Vent between the ply and tin by using insect mesh along the gap at the bottom, this should provide adequate ventilation. I added some vents along the eves as well…. Probably unnecessary but additional ventilation can’t harm a roof like this. 
ignore the arched windows…. Was just playing With ideas. You can see the vents running down the eves.

Thanks @Cpd.... I've always thought you need to have through ventilation, i.e ridge vents widely available for other types of material !? I guess Building Control will raise it when we start building? Might have to go down a proprietary metal ridge profile that allows for breathability, if they insist.  

 

Nice cladding BTW!

 

P.s did you go for the EDW flashing for your Velux windows?
