Is there an acceptable roof distortion amount for atmos tanks?
(OP)
I cannot find anything in the build, repair,or inspection codes that address roof distortion on atmos. tanks. I have a few tanks that have some buckling in the roofs. They are all fixed roofs. What would be considered okay, and what would deem it not fit for service? Is there a standard or good practice?

Won't that make the buckling worse with the weight of the additional thickness of paint - lol

You could also apply the infamous FGT or Fat Guy Test. If you get one of your more stoutly built colleagues (or may be two of them) to stand on the up raised bit and it flexes down then it's OK. If it stays there then think about replacing it or strengthening it...
I don't think there are any hard and fast rules about this as one persons "buckling" is another's small deflection. The roof structure is almost irrelevant to the safety or strength of the tank, more about the safety of anyone walking on the roof.
An experienced tank repair company would probably give you an inspection report, especially if you paid them, but bear in mind they make money by repairing tanks so...., but at least you would have a written report.
Any pictures for people to comment on would probably generate some interest, i.e. whether people think it's a "buckle" and needs repair or not.

My rule-of-thumb is if there is moss and/or algae growing, recommend a repair or improved paint. Otherwise it is cosmetic, and upper management does not look at the tank roofs much. MUCH better things to spend the maint. & repair budget on than wrinkled roofs.
