This Maintenance Management Order (MMO) supersedes MMO-026-83, and provides a framework for assessing and confirming design snow loads for United States Postal Service (USPS) facility roofs. Roof collapse due to snow or ice accumulation is a real concern during winter storms. Therefore, sites should inspect roofs, drawings, and specifications to ensure that the roofs conform to the minimum design loads for building and structures. Sites should correct inadequately designed roofs or develop and document interim procedures for minimizing roof snow accumulations. All sites must post, in a visible fashion, the roof load capacity in pounds per square foot (lb/ft2) at all access doors to the roof. This bulletin applies to Acronym BLDG and Class Code BA.
