Across peninsular India—particularly along the Arabian Sea coastline, the exposed ridges of the Western Ghats, and the cyclone-prone corridors of the eastern seaboard—steep-slope roofing systems face severe aerodynamic pressure regimes. During severe cyclonic storms and deep pre-monsoon convective squalls, 3-second peak wind gusts frequently accelerate beyond 180 to 220 km/h. When air moving at this …
