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.

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