Protecting Aging Homes from Massive Winter Snow Loads
Winter weather in northern urban centres places immense physical stress on aging residential properties. When heavy snowfall accumulates on top of a century-old house, the resulting dead weight can easily exceed several thousand pounds. The wooden rafters supporting this massive burden have often been subjected to decades of slow degradation. Microscopic moisture intrusion, dry rot, or simple age can cause these structural timbers to lose a significant percentage of their original load-bearing strength. As the snow deepens during a severe January storm, the pressure pushes downward aggressively, causing upper-floor ceilings to bow and historical plaster to crack. Homeowners frequently misinterpret these interior cosmetic issues as normal seasonal settling, entirely missing the severe warning signs of structural overload occurring directly above their heads. The danger of this accumulated weight multiplies when seasonal temperature fluctuations create the perfect conditions for ice...
