In your example OP, you listed what anyone doing that job would have had to do.
You need to explain what YOU did "extra special" to make yourself stand out. People reading your resume know you had to make sure the roof was sound, etc.

Project deadlines met 100% of the time, including roof work
with double permit checks
Saved client 10% in energy bill yearly, as calculated by EPC standards by devising innovative way to incorporate *insert fancy solar panel name" on original materials
Passed all city, state and national standard checks, including emissions and materials, on first inspection
Lobbied for collaboration with Xyc company and was successful in establishing contacts that allowed abc
Stop laughing at my examples, I know nothing about your industry
