Default I need to cut a large hole in sheet metal.

Why not. I'll post some photos within the

Start a new thread when you do, and announce where the pictures are.

I deal with several condo buildings where they just have a Raypak
natural gas fired domestic hot water boiler and a storage tank just
sitting out there exposed on the building roof. All you need to
protect from rain are the pump motors.

If nothing else, I've got to see why they would think they need to
seal the unit half inside the roof - they are designed for outdoor
installation.

Unless some doofus couldn't figure out how to properly fix the
section of the roof the boiler is sitting on, and found that sealing
the whole area stopped the leak...

(For something like that, you erect an A-frame, lift the boiler an
inch or two, have the roofers redo the roofing around the pedestal
it's sitting on, and then you slide a new sheetmetal drip pan under
the boiler before you drop it back down. Oh, and drop it on rubber
waffle pads so it doesn't wiggle a hole in the sheetmetal cap.)
