örg Breuning came in touch with green roofs, green roof technology or so called ecoroofs in 1980 as an employee at a German landscape company.

In 1985 he started his own company focused on extensive green roofs. Since 1985 his company has overseen uncountable projects and introduced many green roof innovations and installing techniques.

Jörg brought his extensive horticultural knowledge and hands-on experience to American companies for the first time in 1998. Soon after, Jörg founded Green Roof Service, LLC to serve the ever increasing American market. This would later become Green Roof Technology in 2011.

His expertise is recognized by universities, architects, manufacturers and Installers across the US and in Europe.

After 30 years and millions of square feet of green roofs, there is no doubt green roofs are his passion. He specially recognized for his ability to bridge the gap between theory and practice offering the best management practice and most efficient green roof solutions.

Green Roof Technology, LLC is committed to creating a sustainable new market for a better environment by orchestrating natural habitats, reducing air-born pollutants, reducing the heat island effect, saving energy and reducing storm water problems. His goal is to develop a multi-billion dollar market that would provide many new job opportunities in the USA just like he did in Germany.
