Maintenance Services for Commercial Roofs

Setting Up A Maintenance Program

A Maintenance Program Has Two Aspects:

A Maintenance Program Has Two Aspects:


At least two visual inspections should be made every year. Ideally, inspections should take place in the spring to check on damage that may have occurred in the winter, so repairs can be scheduled during the fair weather, summer months. The second inspection should be in the fall to be sure that the roof is in good condition for the upcoming winter months. Inspection should also be made after any other occurrences that might affect the roof. (Example: storms, hail or high wind events, construction activities, fires, etc.)


All components of the roofing system should be closely inspected and a record made of any signs of deterioration, unusual traffic patterns, poor drainage, accumulated debris, displacement or loss of ballast, or other conditions.
