Clay / Cement Roof Tile Installation

Our Clay / Cement Tile roof system appears to:

Plywood sheating, Tyvak type (fiberglass) over top, the 2 x 2 (?'s) that the tile sit on, and the clay / cement tiles.

Also there are NO roof vents that protrude thru the tiles. Inside the attic we can see 6 or so 6 x 10 inch holes cut into the sheating and a screen put over. The tiles are spanish style and you can see the two small grooves of the tile from inside.

Would this be considered a proper installation as far as the manufacturer installation recommendation, or meet CSA / Ontario Building Code?

We are located in Midland Ontario, waterfront on Georgian Bay.

Without looking, hard to tell. However cutting holes in the roof sheeting sounds a little off to me.Water can travel directly into the attic space if there's ever a problem with the tile.

Most cases, venting is done at the rigid for the attic area. And any summer heat and humidity trapped between the plywood and tile, passes out of the roof system by the 2 by space, if done right.

It may be they tried to vent the attic into the 2 by space if so this is incorrect. Any water that may enter the area will leak into the attic space.

You should contact the manufacturer for their advise, and if need be your local inspector, should you no longer trust you roofing contractor.

Hope this helped.
