Re: Tile Roof Install
Depending on the material, yes it would be allowed, however ...
The main thing I see missing is there is no mortar closure pointing up the spaces between the rake and ridge tiles and the field tiles.
If you don't close those gaps up, the wind uplift design on the roof tile is exceeded and all installation and design requirements are 'out the window', or, more aptly put, 'off the roof' during high winds. That in addition to allowing wind driven rain to enter. The tile (except on System One tile roofs) is not the water proof covering, but it is intended to keep 95% of the water off the tile underlayment, the only way that can happen is to seal the tile where it meets at hips, ridges, adjacent walls, head walls, valleys, etc.
