Portland Ecoroof Program

Portland Building ecoroofEcoroofs replace conventional roofing with a living, breathing vegetated roof system. An ecoroof consists of a layer of vegetation over a growing medium on top of a synthetic, waterproof membrane. An ecoroof significantly decreases stormwater runoff, saves energy, reduces pollution and erosion, and helps preserve  fish habitat. 

Ecoroofs also absorb carbon dioxide, cool urban heat islands, and filter air pollutants. Ecoroofs increase habitat for birds and insects and provide much needed greenspace for urban dwellers. 

More developers and business owners around the world are designing, building, and managing their properties in a way that reduces negative impacts to air, water, and the earth. The result is a growing interest in using ecoroofs and roof gardens. Portland is at the forefront of this exciting green building movement.
