The rooftop terrace that crowns the 10-story Mayo 420 building in Tulsa, Okla., is a popular spot for building residents who come up to relax and enjoy the views of downtown from high above Bartlett Square.
The view immediately underfoot is also a pleasant one, thanks to the self-adhering mod bit system that covers the roof. Attention to detail — such as selecting an attractive roof material, retaining the design integrity of the structure and preserving historic architectural elements — has made the Mayo 420 a downtown jewel. However, until recently, it was anything but.
