Saw some older threads about this. If you're not worried about ventilation like I'm not, I'm doing the dry system this Spring and am replacing an air tight mortar ridge, so there was no ventilation through the ridge in the first place. The unions might not be watertight and the membrane might not be either, and the ventilation is good by some other means. Why not replace the membrane with a strip of roofing felt, glued to the top row of roofing tiles? Just making sure any water that does get in gets out too but any mice or birds can't get in.
If Worried About Dry Ridge System Leaking

Why would you not use the materials provided in the dry ridge kit?
Few people worry about ventilation - until its too late.

No water will get in, just use the proper kit.
I will but someone was worried about it leaking.
In my case the ventilation is plentiful via other ways than the ridge area.
The ridge tiles are bedded in and pointed, where's the air going in?
I suspect you're right, I haven't seen the kit yet myself, but someone was very suspicious earlier in an earlier post.
But I'm not of the roofing world, just a DIYer who only pays someone else if the boiler or radiators need work. Might not look 100% professional or mint, but I won't have to curse that roofer who didn't give a damn or had too low an IQ to understand how water always tries to find the easiest way.
Always good to have a drafty loft.
