    Default G'day Renno members...I got a sheeting problem

    Been a member for a while and been avoiding renno's...but time's caught up with me.
    I have to replace a rusted corrugated iron sheet on an awning. The external air-cond unit is sitting on it, with penetration for pipes through the sheet. The slope of the awning is toward the front of the building, into a box gutter. To put the unit on the building face, I would need to relocate the pipes around/over/through the box gutter.
    Should I try to relocate the unit onto the building face or keep it on the sheet, and if so, what is the best way to waterproof a penetration?
    All advice is appreciated. Thanks

    Two ways to do it
    Plan A
    Best way is get the unit degassed and disconnected, including electrical, which I must assume comes through the roof as well.
    You can then simply move the unit to a convenient spot while the roof is renewed, with small holes cut in the sheets for penetrations and seal penetrations with a dektite.

    Once the roof is done get the air con installer back to reconnect and watch him dent your new roof bc they don't care

    Plan B
    Leave everything connected and cut the holes then slot the sheets for the penetrations and patch over the slots, and again, use dektites.
    But of course you need to raise the unit and keep it raised in order to remove/replace the roof
    Not easy to do.
    Be warned
    You may have to batten under each side of the slotted sheets.
    Also you may have to replace battens depending how the roof is presently fixed so this can throw up more problems.

    Which in all means Plan A is best.

    Have fun.

    Thanks for the great advice Cyclic. One question - do I have to disconnect the pipes to use the dektites?

    Not if you get the retrofit variety.

    Retrofit meaning the dektites have, for want of a better description, a zipper, but they must be well sealed, and as in plan B, the unit has to be suspended while sheets are removed/replaced and,
    it can be troublesome slotting sheets and resealing them to get them around the pipes/conduit,
    especially if the pipes/conduit are close together, hence plan A is always the preferred/best practice.
