How often should a commercial roof be inspected?
Many commercial owners schedule inspections twice a year—commonly spring and autumn—and after severe weather or rooftop trade work. Building risk, warranty terms and roof condition may justify more frequent checks. Spring can reveal winter damage, while autumn cleaning prepares drains and details for sustained rain or snow.
Seasonal checks catch different problems
Spring can reveal winter damage, while autumn cleaning prepares drains and details for sustained rain or snow.
Events create extra risk
Wind, hail, heavy snow, equipment service and new rooftop penetrations can create defects between scheduled visits.
Records turn inspections into management
Use the same roof map and condition categories each time. Track recurring repairs, ponding and wet-insulation concerns.
Details worth checking
