In sub-zero alpine belts—such as Kashmir, Himachal Pradesh, Uttarakhand, and the highest reaches of the Nilgiris and Western Ghats during extreme winter incursions—steep-slope roofing physics encounters an aggressive phase change: frozen precipitation. When rain turns to heavy snow, the structural demands on a roof envelope shift from transient water shedding to long-term static dead-load resistance, …
