The best time for the establishment of a maintenance program is during the roof s design and construction. Roofs that are built with maintenance in mind can reduce significantly the yearly operational costs of a building. Upon completion of the historical file, the implementation phase can commence. This normally consists of a roof survey, during which the condition of the roof is assessed and all anomalous conditions are located and identified. The information obtained from the surveys is used to develop repair and maintenance recommendations and long-term roof replacement budgets.
Regular inspections form the foundation of the roof survey.
These should be carried out at least twice yearly. An inspection in the spring reveals any possible damage resulting from severe winter weather and identify any corrective action required. Repairs can then be made under the most suitable climatic conditions. A fall inspection reveals any preventive action that is required before winter. In addition to the spring and fall inspections, the roof should be examined after any major weather event or construction activity that might have caused damage to it.
