Has anybody used Cor-A-Vent ridge vent products on a tile roof application? Their installation detail depicts a vertical nail through the ridge of the tile and into a nailer sitting on top of the rafters. My questions (having never seen an installation) are:
What waterproofs the tile with a nailhole and nail running through the peak? The ridge tiles I’ve seen here in CA nail near the edges, not the ridge, is that a construction technique particular to the east coast?
Is the nailer they show installed by the roofer just for the vent application (I’ve never noticed such a nailer on a non-ridgevent tile roof) and how would such a nailer be installed without blocking the gap between the plywood purportedly to be used for venting?
I’ve asked the company these uestions, but really need an unbiased opinion if you know what I mean.
Thanks,
FK

I've not used coravent on tile applications, but all of the tile roofs I've worked on (mostly Ludowici tile) have a ridge or hip board to nail the hip or ridge tiles to. The nail hole in the tile is covered by the next tile. The ridge nailer sets above the ridge beam or would be centered on the ridge with gaps in the plywood on either side of it in truss construction.

That makes sense, the weatherproofing is via the overlapping tiles.
Thanks for your help.
