For a long lasting and safe roofing system, you will also want to keep a record of all roof inspections, repairs, and maintenance performed. Yes – write everything down! Did you come across missing or torn flashing that requires replacement? Are there any sloping areas that need to be fixed? Any issues you spot – as well as any issues that have been taken care of – should be documented. That will help you track all important information about your flat roof. This will come in handy when it is time to think about your replacement options.
