I am a general contractor who specializes in small repairs and remodels. I do not do roofing. I am trying to confirm something that was told to me by a roofer regarding the installation of concrete roofing tiles. He says that not all concrete roof tiles have to be nailed on. Some can be “pressure fitted” or “glued” into place. This seems contrary to common sense to me but again it is not my area of expertise. Perhaps certain manufacturers have this approved?
Any help or direction would be appreciated.
Thanks,

My tiles had a "hook " cast into them . The tile was to be laid over a batton on the roof , the hook held them in place . The instructions stated that only the rake and eave shingles had to be fastened . exept in high wind areas (80mph and over) and roof over a specified height . The roof tile that I used weigh 9.5 # each and inter lock with the next one .
I've installed roughly a hundred concrete tile jobs. FWIW on pitches under 10/12 or so I never fastened any tiles to the roof other than trim tile, o step roofs I nailed every other tile every other row one nail on the right side of the tile, with concre tile this is plenty of fasteners. Valley and hip tiles can be glued to each other, in Florida tiles must be fastened to roof either mechanically or glued/hot tar to roof deck. Im not sure about other locales.

The old ones here in Southern CA (from the 1920's) are nailed or wired to a nail. They came with a hole top center of every tile. I carefully pulled three squares of the multi-color concrete ones off my place, and gave them to a neighbor who wanted them for repairs and remodeling. In earthquake country, it's a bad idea to put that much weight up high.

In my home in florida the concrete tiles are secured with a urethane material (glue) no nails.
