Purple-Roof knows how to deliver a real ROI that justifies your property's investment in a green roof. By capturing and managing stormwater on the (Purple-) Roof, we help you save space—eliminating the need for additional tanks or bio-retention systems at ground level. Space equals money.This approach builds on over a decade of experience in providing green roofs with Sempergreen Sedum mats, during which we’ve learned firsthand what works in North America and what doesn’t.Purple-Roof is a science-driven, non-proprietary solution developed through unparalleled field experience. It’s not about thinking we’re more intelligent than the industry—it’s about our deep understanding of how these systems work together. Our extensive research and decades of experience set us apart.Relying solely on policy compromises performance. That's why we’ve invested heavily in green roof R&D and are committed to continuing this work. Our team includes civil and environmental engineers, Ph.D. ecologists, software engineers, landscape architects, plant and green roof experts, and soil scientists, all working together to create the most holistic green roof technology available. Our systems perform optimally in the first storm and continue to excel in the second.If you're interested in eliminating the need for a tank or bio-retention in your next project—or if you're unsure why this is important—get in touch with us.Email: dick@sempergreen.comVisit our website and blog at www.purple-roof.com, or call me at (301) 219-4071.Moerings Sempergreen Sedum mats are a key component in most green roof systems offered by waterproofing membrane companies across North America.
