The general public has two perceptions of the words “green roofing”. The first is the literal definition: a roof filled with live greenery. That is the most common meaning, but there is also the newer and more frequently used meaning for “green” which is as an adjective for anything that is designed to preserve our natural resources. That would make any roof with solar panels or wind turbines a “green roof”. If you’re contemplating the installation of a new roof on your home, either selection is a good one.
In ancient Scandinavia and the British Isles, the traditional “sod” roof was a common fixture on cottages that dotted the countryside outside of major urban areas. It was learned early on that these purely organic roofs kept out wind and rain, and they insulated the occupants from the cold of winter. They were also, and still are extremely durable, requiring very little maintenance and rarely need to be replaced.
Today, the concept of the sod roof has been taken to a whole new level. Massive skyscrapers around the world are now capped off with spectacular “roof gardens” that help keep in the heat and air conditioning of the buildings below. The added greenery in bleak urban settings also improves the oxygen content and gives residents an opportunity to experience outdoor growth they wouldn’t normally see down below. The most notable of these high-rise green roofs in on the HSBC Headquarters Building on Canary Wharf in London, the 22nd largest building in the world. Click here for more information.
Of course, you don’t need a skyscraper to have a green roof put in. Normal everyday homeowners are electing this option more and more as the benefits become more apparent. Green roofs are more cost effective. If you combine the greenery with some alternative energy sources like solar, wind, or thermodynamics, you could turn your home into a totally self-sustaining property. If everyone chose to do this, the world would definitely be a much “greener” place.
