is the premise already built ?
I would not take roofing (metal) ever, a good wireless system is the way to go.
I am in th middle of an install that involves lots of reeds in a domestic premises that is steel framed , colourbond roof , 13' ceilings & dropped eves.
Would anyone like to share some of their installation tips for a job like this ? I can't see an alternative but to lift some roofing iron. By the way it is not brick / veneer with a cavity - it is rendered bluboard on a standard (steel ) frame.

What's wrong with lifting a sheet of iron? Just allow for the extra time and have some new tech screws with new rubbers on hand.
I hate steel frame so glad I have a roof monkey .
hmmm, i wouldnt be lifting roof sheets either mate. If you do be really careful abd try not to pull the whole sheet up. They can be a real pain to get back down properley and your asking for trouble later.
As Keefy said a decent wireless system would be the go, judging by the amount of reeds it sounds like youve got to put in. It could look pretty ugly otherwise
Hey Watchdog Lift some sheets. Have had to do it a few times just be careful. I can already hear other techy's groaning at the thought of the extra work but if its gotta be done i havnt had a problem in doing it and will lift them again. Anything to get the job done right.
grin and bare it!!
its part of the job.
i had to do it on a camera job not so long back. Just always concerns me that your the first one to blame should the roof leak afterwards & no im not talking from experiance
You won't have to remove the entire sheet, just remove enough screws to lift the sheet at the gutter end to reach the walls top plate and drill a 20mm hole in it, and a length of conduit to throw in the roof toward the man hole.
Don't forget the rubber grommets to put in the holes you make, the steel is pretty sharp.
Good thing about steel frame is that there are no noggins so you only have to drill the top plate of the wall, everything from there is free fall to the ground.
And like rotor said, grab some new rubber washers to replace the ones on the roofing screws you remove.
eeeek i would stayy clear of removing roof sheets :P
your call mate
Well you can be really messy and run duct up the walls :P
With no cavity and from the sounds of things no space to get directly above the wall lifting tin is about the only option to get to the top plate.
Unless with the dropped eve you can come out the side at the top, then long piece of fencing wire and a conduit with hook on it to fish it out of the eve sometimes works.
I would check that out. I have never seen a steel framed load bearing wall without noggins. A internal non load bearing partition or wall is a different matter.
@watchdog
I also would not be taking any roof sheeting apart without getting a written indemity from the client first. You will get blamed for any mishaps espcially if the house is still under the 7 year warranty.
You will also find that the cavity will be filled with insulation. You should also be careful not to cut or damage the sarking as on a steel roof you can get a lot of condensation in certain conditions.
I hope you quoted D & C on the cabling part of the job.
What the problem is that with 13 ' ceilings there is about 2.5 foot between the window header & top plate of the frame. Yes this is filled with insulation. The ONLY way to access this area is by lifting the roof sheets off.
By the way - how do you do multiple quotes?
I would not hardwire it, no way, infact if they wanted me to pull roofing sheets off, i would walk away, rather not do the job.
Not entirely true, if the frame company uses the cheap 70mm studs then I'd say yes there will be noggins, but if they are using 90mm then there isn't. Also when they build the walls they cross brace it with straps hence no need for noggins. All depends on what option the owner has chosen. Let's hope he didn't take the cheap road.
