Roof spigot plumbing

I have a single story ranch with a flat roof. When the house was built a spigot and upward-facing shower head were installed on the roof to make it easier to cool the hot roof in the summer. Some time ago I forgot to shut the valve off inside and the pipe to the roof burst and leaked. I don't absolutely need the plumbing up there - I just keep the valve off now - but I'm wondering *if* I could fix it...

Copper pipe runs from the basement straight up to the roof. This amounts to about ten or eleven feet of vertical pipe. I might be able to pull the pipe up from the roof, but...I'm wondering if the pipe would have been fastened to the wall studs somewhere along the way. If fastened, I have no way to fix this and I could just remove the roof spigot and patch the roof and terminate the plumbing in the basement.

So, what is the likelihood that the pipe is fastened to the studs inside the wall? Ten feet of pipe has got some weight to it.

Thanks.

Why mess with it?
If it's shut off and it's not leaking I'd just leave it.
Your opening a can of worms trying to remove it totally.
Where on the planet are you, this is the first time I've ever heard of anyone trying to cool a roof using a sprinkler.
I can think of lot's of reasons why this was just a bad idea someone came up with.

Interesting idea. Member location is Pennsylvania.
The rooftop ice skating would be good in the winter.

It's not unheard of in Pa, especially in the classic flat-roof Philly rowhouse roof can reach 190+ during summer. Spraying 60 cold water on a 195 roof can be cheaper and more effective than running a window air conditioner.

Here's an experiment- try walking barefoot across a black asphalt driveway at 2pm during a sunny august day. Then spray it down with a garden hose and try again...

I would count on it being fastened.

Here's the roof spigot if anyone was curious. Nozzle on top is broken. Top handle controls the nozzle. Bottom handle is a spigot for, say, a garden hose.

What would the base, where the pipe meets the roof, be made of? I need to redo that. I'm pretty sure it leaks there. You can see some of the rubber already lifting, but that square base should have been tapered to prevent water sitting there. There are a bunch of pinholes in it.



EDIT: Moved question to a new thread in "Roofing".
