A steadfast commitment to combat the effects of our ever-changing climate through the provision of green roofs and green amenity spaces.

Founded in 2010, Columbia Green Technologies (CGT) has always had an overarching goal to empower building owners and their investors with long-term returns on their ESG (Environmental, Social, and Governance) investments, reinforcing the notion that responsible business practices can yield positive outcomes. 

However, the advantages of green roofs extend beyond mere financial gains. By seamlessly integrating nature back into the building environment, these innovative systems offer a respite from the concrete jungle and contribute to improved health and well-being. The extensive range of green roof systems and amenity deck products cater to both new and existing commercial and residential structures, ensuring accessibility and adaptability across diverse architectural landscapes.

As President and CEO of Columbia Green Technologies, Vanessa views green roofs and green amenity spaces as a nature-based solution to assist with building resilient communities for the future. She and her team are committed to creating a positive environmental and social impact by building vibrant, resilient cities and replacing aging infrastructure with green infrastructure. The company's products are proudly manufactured in the USA and adhere to rigorous standards. Not only do these products meet the esteemed LEED V4 certification requirements, but they also carry the esteemed Living Building Challenge Declare label. These accolades underscore the dedication to championing sustainability and pushing the boundaries of eco-friendly design.

Innovative green roof technology

Columbia Green Technologies offers comprehensive green roof solutions for a variety of situations: extensive, semi-intensive, and intensive roof gardens. Green roofs, also known as vegetated roofs, are increasingly common because of their beauty and myriad of environmental benefits, including the creation of habitat, reduction of heat island effects, and management of urban stormwater runoff. Our products were engineered to maximize stormwater retention and create an environment for optimal plant health.
