4 buildings collapse in Chicago and Elgin over 3 days: Are back-to-back snowstorms pushing old roofs to the brink?


“The issue with a few of these buildings is, as the snow falls and freezes, it could actually push in opposition to the edges of the roof, and that may trigger some movement that can trigger rafters to collapse or to fail,” Langford stated. “In some buildings which can be simply massive, open roof space, it’s simply the sheer weight. On wooden that’s 100 years old, it simply goes.”
