    Hello, we've got a motorhome thats already fitted with a roof mounted setup and the cable was fixed down with self adhesive cable tie bases but afterwards a couple of years they have deteriorated and come away. I think the answer maybe to use white rectangular cable trunking and stick it down with sikaflex type sealant, what are the alternatives. ?

    Any advice would be appreciated

    Go with your own thoughts :xThumb:
    Personally I use self adhesive trunking and just seal the sides with sikaflex

    I used a length of YT2 cable trunking to secure my solar cables as you say.
    YT2 is around 20mm wide by 15mm deep.

    If yours is for a sat dish cable you could use YT1....15mm by 15mm, it should easily take one sat cable.
    You can buy sticky backed but still needs a line of sikaflex to be safe.

    Makes a neat job

    I reckon the white trunking is the way to go, it comes plain which you could stick or with a self adhesive tape the tape would my choice.

    Yes I thought about that and the UV Rays would probably not deteriorate the adhesive too bad although the sikaflex would perhaps be more permanent

    I use sticky back almost every day in my job.
    The tape sticks like shit to a blanket indoors on a smooth clean surface, but doesnt weather too well outdoors.
    Still needs a bit of sikaflex to make it permanent.

    The adhesive backing is fine if the roof is clean but it is foam and will absorb water if not sealed along the side too

    Ok then standard trunking, no tape to deteriorate and a nice neat line of sikaflex along the underside and seal the ends of the trunking with a splodge of sealant.
    Thanks for the suggestions

    Yes you have the luxury of time. Just don't try putting the cables back until the adhesive as set.
    On a one day job self adhesive is essential as the cables have to go in straight away to complete the task.

    Just bought this kit plus a reel of 4 mm solar cable for £15. I have a mate who will make me the stainless brackets FOC to mount the panels to the roof. Total outlay should be about £200 for 240 Watts of solar power.
    Thanks for the heads up with the sticky backed trunking I'm going to use.

    I use 6" nails. :xThumb: The cable never moves, but you can scrape your head moving around inside.

    Simple answer is to just fix the cable with dabs of Sikoflex at regular intervals.:xThumb:

    Yes I think that is the most practical method especially as the cable is routed in a curve to avoid a roof vent, thanks for the suggestion

    When I put the solar panel on our roof, being a PVC using rigid trunking wasn't an option due to the undulations etc, so I placed the cable where I wanted it and used some gaffer tape strips to temporarily hold it down then with Sikaflex I stuck some cable clips over it (those used for electrical cable in a house like the below) ... mine were white and I removed the nail ... although I suspect Toots wouldn't! :rolleyes:

    Same as Andy except I use silicon along the sides makes life easy if I ever need to remove it.

    Although it will do the job it looks tacky and makes cleaning the roof a pain.

    It also has the advantage that water can pass under the cable so shouldn't cause puddling on the roof.

    No more than trunking and I don't look on the roof too often!:wink:
