How thick is the PH roof?

[Cheapie408]

On an 05 2120, how thick is the roof material? Was told by parker that that transom is 2.5" thick forgot to ask for the roof. Need to buy some bolts to mount a radar pedestal.

Wow, I was expecting the roof to be thicker than 7/8. Thanks for this, very helpful information.
