Government figures have shown that water-related events – including flooding – have surpassed forest fires as the top cause of property damage in Canada in the past several years, costing homeowners more than $1 billion in losses annually. Despite the threat, a recent study has revealed that an overwhelming majority of Canadians living in high-risk regions are not only unprepared to deal with the impact of floods, but they are also unaware of the potential danger.
Blue roofs could help reduce the flooding effects of big storms
You've probably heard of a green roof, which sits on top of a building and is covered with vegetation. But what about a blue roof? You might have guessed that it has something to do with water. Indeed, a blue roof collects stormwater through a pond system, temporarily stores it and gradually releases it afterward — offering a way to conserve water and prevent water damage. During a storm, rainwater can overwhelm urban sewer systems and send contaminated, untreated water into lakes and rivers. A blue roof could help solve this problem.
