A roof structure and method of constructing the same wherein a large clear span is built over an existing or new athletic stadium or arena. The principal feature of the roof structure is that it is supported by Cable-Stays to towers standing outside of the stadium and places no additional weight on the existing stadium. The invention is particularly concerned with such a method and structure wherein the central section of the structure is not cantilevered from the towers and thus does not impart cantilever loads to the towers. The structure includes a beam framework and roof covering installed over the framework. The covering is fabricated of a clear skylight material to allow sufficient light transmission to permit a natural grass playing field and is openable to allow for ventilation.
