Big sky light removal / reseal

[AlyJay]

Hi Guys, I'm wondering if anyone can give me any tips on removing large (middle forward) skylight in photo.
The sealer is very skanky and coming out so I would like to do this before it starts to leak.
I'm totally new to motorhome ownership but I am very practical and am ok at mechanical stuff.
Is there anything to look out for during removal and refitment? I'm guessing its sealed in then tightened with screws?
I would also like to redo the sealing on both the front and rear roof joins as this has started to loosen by looks of things aswell.

Thanks Alistair.

I removed the large tilt skylight from my Burstner by using a cheese wire (it was actually mig welding wire) cutting through the sealant cleaned re sealed tightened down waited for a short while to allow to settle then gave another tighten, job a good un.

I did wonder if I would need to cut sealer with something - thanks for tip I will cut some mig wire and use that as you say.

I got a mobile repairer in because I new it would heart if I fell of the roof.

I assume that you are referring to the sloping sunroof at the front, and that it is non-opening. Be extremely careful what you do. Hobby had a recall some years ago on a number of models because the adhesive used was beginning to fail (due IIRC to being insufficiently UV-resistant) and the sunroofs were flying off at high speed, not only leaving a large unprotected opening in the roof but also causing serious road safety issues. The repair involved either Hobby dealerships or, if none conveniently located, National Windscreens, who sent out their coach windscreen teams (2 guys, each with a van, scaffolding for access, etc., etc.). If you intend to undertake this work yourself, be aware that it is safety-critical and ensure that you use the correct materials and procedures.

Hi there, no its the centre forward skylight, not the fixed glass over cab as that is bonded into position and looks fine.

My bad. I assumed that one because the other had the blind across in your photo!
Sealant for rooflights is best obtained in a roll rather than using tubes of sealant.

I guess you are referring to Butyl Tape? Guess it is a preference. I used that for my Maxx Air Fan. If I were doing it again, I wouldn't use the tape again.

I've bought some silicone type stuff called OB1, it's in a tube and is apparently very good and gets very good write ups.

We also used the tape.It was much easier to get into place and to lay an even layer of I think 1inch wide all around the gap.
