Concrete Tile Roof

[newStruc]

I was figuring out the dead loads for a wood tower on a wood building. The wood tower has a concrete tile roof. I was planning to use 15 psf as weight of my tile. My co-worker is saying I am being too conservative. He says the weights vary from 9 to 12 psf. What is the general weight that I should assume for concrete tile?

Do towers have sprinkler systems, I would like to know if I need to add the sprinkler dead loads to the tower dead loads as I did for the main roof.

I agree with Mike McCann. Tell the contractors what loading you included in your design. That should be based on realistic values from concrete tile suppliers in the area. If they want to use something much thicker and heavier, obviously the roof design will have to be reviewed.

Thanks for all the help guys.

The architect finally decided to have a specific tile. He is going with US tile (two piece mission clay tile). Thats only 10 psf. So my total dead load is about 20 psf.
