Missouri S&T Green Roof
The Missouri S&T Green Roof atop Emerson Hall features 16,000 plants arranged in the shape of a shamrock and provides research and teaching opportunities for faculty and students. Most of the plants growing on the roof are a variety of sedum and all were chosen for their ability to thrive in direct sun and wind with limited water.
The roof is divided into three sections, each covered with different roofing materials, which allow S&T researchers to compare the water runoff control, water quality and thermal properties of each material.
The first section is a standard black rubber roof. The second section is covered in white thermoplastic polyolefin (TPO) roofing membranes. TPO roofing systems are believed to improve a building’s energy efficiency by reflecting heat from the sun. They provide resistance to ultraviolet, ozone and chemical exposure.
The third section is a GAF-produced GardenScape roof. A base layer of TPO material is covered by a drainage system and then topped with regional vegetation planted in a growing medium similar to the topsoil found in central Missouri.

The green roof and its subsequent research projects were made possible through a unique collaboration. The physical facilities department at S&T led the design of the roofing project and placed the green roof mat and growing medium on the roof. More than 50 S&T volunteers placed the plants.

Materials for the roof were donated by GAF Materials Corp., the nation’s largest roofing technologies firm. Helene Hardy-Pierce, vice president of technical services for GAF, was instrumental in securing the donation. Hardy-Pierce is a 1983 engineering management graduate of Missouri S&T and is a member of the Missouri S&T Board of Trustees.
