What if the flat rooftops that define much of Greater Boston’s housing stock could become vibrant, functional green spaces? From triple-deckers to small multifamily homes, these underutilized surfaces hold untapped potential to reduce urban heat, manage stormwater, and support biodiversity.

Join Cambridge resident and engineer, Nicolaii Cauchy for an intimate roundtable that explores what it would realistically take to make green residential roofs more common across the region. Drawing on decades of hands-on experience navigating building, design, and regulatory landscapes, our session leader will ground the discussion in real-world considerations—while opening the floor to new ideas, shared challenges, and creative problem-solving.

Together, we’ll examine the structural, policy, and financial factors that shape what’s possible, and highlight resources, tools, and pathways available to homeowners and communities interested in reimagining their rooftops. Whether you’re a resident, builder, policymaker, or simply curious, this is an opportunity to engage in a practical, forward-looking dialogue about how we can collectively transform overlooked spaces into assets for both people and the environment.
