Interesting Roofs from Around the World
Although green roofs are more common in Europe than in the USA, they are gradually gaining popularity on the western side of the Atlantic. The roofs are made of either two to four inches, or up to one foot of a mixture of soil planted with hardy plant species. Under the soil, there are layers of membrane that protect the home’s structure from water damage, and they allow excess water to drain rather than cause the soil to slide off the roof. A new Eco-friendly residential roofing option is Eco-shake roofing. Learn more about another “green” roofing type called eco-shake roofing.
