Default Tough roof drain problem. Calling THT brain trust.

This is a roofing / plumbing nightmare I am having on a job right now.
It's a large re roof job and I can not get the clamping rings removed from the roof drains. The bolts are corroded to point where the heads deteriorate.
I tried grinding the heads off and applying monkey piss and using vice grips on the bolt that is remaining. 3 out of 4 are snapping off. Now I am forced to try an EZ out tool but I can't imagine it working.
Help!! Any ideas?

Grind them flat and either retap if there is metal, set with a tapcon if concrete or drill and epoxy a threaded plug.

Good idea. I just left Home Depot with the ez out set. If that don't work I'm going to try and drill out the 3/8 bolt and retap in the same size.

if you break the ezouts off in there you will have a very hard time drilling them out

Hire a plumber to replace the whole unit from inside

These things are attached to the twin tees then poured in 2" of concrete then 3" of light weight concrete so that's not an option.

So what I had to do was grind off the heads and remove the clamping rings. This left about 1/2" of bolt sticking up that I could grab with five grips. 2 out of three will come out like that.
The ones that don't come out, I drill out completely, re tap and installed helicoils.
the only place to put a bolt is in the original location as the hub is casted to accept the bolt only in that location.

Maybe a left hand drill. Ez out is a option...but like 99 yam said, be extra careful !

I'm thinking he doesn't want to bust up 5" of concrete around 25 drains.

Just giving you a bit of a hard time.

Well guys it's not as easy as it sounds working for the school board bond job.
We don't have a plumber under contract in the guaranteed maximum price provided.
Anything on these GOB school jobs has a lot of red tape and we cant do the unforeseen work for free.
Well in this case we are doing it for free but it's costing pennies compared to getting a plumber through the red tape and costing thousands.

Dam

I work for a large school system and roof drain replacement is standard on all of our jobs.

There is also an allowance for unforseen
circumstances. Usually 10% of base bid. Makes situations like this much easier to deal with.
