Preventing Snow and Ice Damage at Fallingwater At Fallingwater this week and throughout the winter, maintenance staff regularly remove excess snow and ice as it accumulates to prevent damage to the historic home. Structural failure or collapse is within the realm of possibility with an excess load of accumulated snow and ice, although the greater threat of damage is moisture infiltration. Prolonged ice and snow buildup can cause ice dams that allow moisture to enter and cause damage to both interior materials and structural members. Below are a few ways to prevent ice and snow damage. Before: · Inspect the roof structure in attics for signs of cracked or sagging members due to snow or roof overload. · Keep roof drainage systems clean and free of obstructions. · Inspect building insulation and vapor barrier systems, and seal gaps in vapor barriers and add insulation as required to meet current energy code requirements. (Ice dams will develop at the roof eaves due to heat and moisture flow from the building interior). During: · Monitor snow accumulation and remove if possible. · Provide temporary bracing under roofs that could be overloaded. After: · Remove snow accumulation from roof. · Brace ceiling/roof areas that show signs of stress or are sagging. The above photo of Fallingwater was taken this past week by Cara Armstrong.
