Recognizing the benefits of green roofs, Vancouver’s council voted for the development of a green roof policy that could require some new buildings to include rooftop grasses. The good news for existing commercial building owners wanting the benefits of a green roof, is it’s cheaper to retrofit than build from scratch.
A commercial re-roof to a green, or “living” roof, is created by laying down a waterproof protective barrier, a root barrier and possibly a drainage system (depending on the size of square footage the roof covers and its complexity.) Soil and select vegetation are planted on top. This system confers a number of environmental and financial benefits, including:
Reduces the urbanheat island effect which reduces energy costs
Helps regulate the building interior temperature, reducing energy consumption and costs
It’s lightweight, low-cost and low-maintenance.
Commercial roof retrofitting is an economical way to save money, increase energy efficiency, and contribute to environmentally friendly sustainable practices. Since the number of existing buildings exceeds new ones being built, the environmental benefits are much larger with commercial retrofitting. The more commercial buildings re-roofing with this technology, the more savings their owners will enjoy.
