    I intend fitting a second solar panel but to to make space on the roof I shall have to move the existing panel which has been fixed down with Sikaflex.

    Any ideas on how to remove the Sikaflex, preferably without the use of a chainsaw, would be appreciated.

    I stress that I have not done this myself but I understand you can slip a thin, sharp blade (or one of those wire saws) between the bracket and the roof and cut through the cured Sikaflex...

    Thanks for that JJ ...... I did experiment with a Stanley Knife but found the sealant too hard. Hopefully there is some way of softening the Sikaflex first.

    I used a full length of guitar string. wrapped it around two short lengths of dowel and pulled it through the gap.

    Came off really easily.

    Cleaned it up with a sharp chisel and then some spirit (can't remember the chemical sorry)

    Removing Sikaflex

    I have just removed my panels before part-exchanging the MH and then decided to reove the brackets which were sikaflexed-only, no screws to the roof skin.
    Fortunately I had bonded the brackets on following the instructions to ensure the sika was 1-2mm thick using some small washers buried in the sika to give approx 1mm thickness,

    I used a length of nylon kit-string but any multi-strand nylon or maybe strong cotton will do the job.
    Just use it as a cheese-wire 'sawing' it back and forth. take your time and keep changing it if it frays/snaps.

    Removing the remaining sicka from the roof ( if you really need to ) will be difficult without damaging the roof surface as I don't know of anything that will remove this cured bonding agent.

    I used extensively Tech T7 when I built my campervan, simply amazing new product of the M7 Polymers...same as the Marine Sikaflex but in my opinion far better cheaper, more flexible, do as the other posters say but if you can, use a gentle hot air gun setting to warm up the area, I then use T7 adhesive remover to clean up:thumb:
