GRiT is the Green Roof Info Think-tank

The Green Roof info Think-tank (GRiT) is a network of businesses, government agencies, non-profit organizations, researchers and community members joining together to grow the knowledge and use of green roofs in the Pacific NW.  

GRiT is a registered 501c-3 non-profit organization.  We host monthly meetings, seasonal tours, lectures, community outreach efforts, and semi-annual green roof symposia, among many other fun events.
