The roof is the fifth side of a building and usually the first one surrendered to machinery and heat.
Reclaiming it begins with unglamorous questions: structural load, drainage, wind, safe access and who will maintain the result in February. Only then do gardens, solar arrays and public rooms become credible.
Roof type A Water before spectacle. Deep channels slow storms and feed shaded storage. Planting is selected for survival, not launch-day color.
Roof type B A corridor for more than humans. Pollinator habitat connects parks otherwise separated by traffic. Night lighting stays low enough not to turn the corridor into a trap.
Roof type C The public room above noise. Seating, shade and clear access make the skyline part of daily civic life. A useful roof is not an exclusive view; it is connected infrastructure.
