Guide in inspection of pre-engineered metal building roof
Guide in inspection of pre-engineered metal building roof
(OP)
The Pre-engineered was constructed building 1982 and is 182 feet by 70 feet.
Recently had some hole in different location on roof and at some location ceiling insulation has just hung
It is the possibly some roof purlins are rusted.
Shall I inspect 182 feet long building for purlins damage???
ceiling is 32 feet up.
How do I get up there and check 182 feet may be 6 or 8 purlins
What is the industry practice
Thanks

How do I measure the length of damaged with camera on the ground?
Thank you

If the rusting is due to high humidity in the whole building, that is another matter - the whole building should be checked after a contractor pulls down the insulation.
I would be far more concerned with the mainframes than the purlins for any rusting.
Hopefully none seen on the mainframes.
