Glacier National Park is planning to re-roof the Many Glacier Hotel (National Historic Landmark) this fall.  The original roofing material was a cement asbestos tile placed in a "honeycomb pattern" (basically a diamond pattern with the bottom point cut off).  The tile was replaced with wood shingles in the 1950s.  The only manufacturer identified with a similar substitute material is Cembrit of Denmark.  The company will not warranty its product for installation in this environment.

Has anyone found an appropriate substitute for cement asbestos shingles in
this pattern?
