Snow load and ice dams on aging roofs
Heavy seasonal snow and repeated melt-refreeze cycles drive roof accumulation and ice dams that force water under eaves and into walls. MUBEC requires ice-and-water shield at eaves and valleys for new roofs, but older buildings with poor insulation and ventilation are highly prone, and there is no retroactive snow-load re-evaluation of existing roofs. Confirm roof age, ice-and-water-shield condition, and any history of ice-dam water intrusion in the minutes.
