Earthquake-prone areas require special attention as well. Properties in these areas should be designed and constructed according to seismic details specified in local building codes. Storage racks, boilers, transformers, tanks and other large equipment should be braced and anchored securely to help prevent toppling and sliding. Sprinkler and process piping also will require special installation techniques. Protect roofs from excessive loading either from ponded rainwater or snow accumulations.
Design roofs to withstand anticipated loads from drifted snow and layers of ice.
Carefully remove snow soon after a storm to avoid additional loading from ice, snow and water.
