"Ancient Roofing Technique Halves Yearly Rainfall Impact for Modern Homeowners"

In Washington D.C., architects Mark and Lucia Freeman installed a green roof on their home, an ancient method that provides environmental benefits such as reducing annual rainfall runoff by 50%, creating habitats for wildlife, and improving energy efficiency by lowering summertime energy costs by 15-25%. Despite the higher initial cost, the green roof offers a sustainable solution to urban heat islands and heavy rainfall, while also being a cooler alternative to traditional roofing materials. The Freemans' choice reflects a growing interest in eco-friendly home features that can help mitigate climate change impacts.
