Green roofs are increasingly being promoted as a way to help cities cope with rising summer temperatures. By covering rooftops with vegetation, these systems can provide shade, reduce surface temperatures and help cool surrounding areas.

However, installing a green roof is only the beginning. Many projects struggle to survive beyond their early years because of inadequate maintenance, unsuitable plant choices, water shortages and harsh urban conditions.

Experts say the long-term success of green roofs depends on proper design, regular maintenance and selecting vegetation that can withstand local weather conditions. Without these measures, roofs intended to combat extreme heat can deteriorate quickly, reducing their environmental benefits.

As cities continue to experience hotter summers, ensuring that green roofs remain healthy and functional could be just as important as building them in the first place.
