Making holes in my roof

[Ber-Tech]

Hi every one ,cleaning up a newly bought mk7 that is in the need of some TLC
- looking to put a solar panel, some lights and a camera on the roof of my Mk7. my question is this - how do i make the holes i make water proof max hole 15mm- have made a couple of search's but cant find a fool proof way to do it. don't want to wreck my new headliner

On the outside of the roof... what you need is sikoflex marine grade (white ,, assuming your van is white ) its a million times better than any silicone for sale,,, if the outside is sealed correctly ... then you don't need to worry about the inside BTW sikoflex is also paintable ... silicone however isn't .

When I put the roof vent in my MK6, I measured, measured and measured again before cutting the hole.
Because the roof is ribbed, I had to build it up with Sikaflex and then "sunk" the vent into the hole.
I waited for the 1st real heavy rain and there was the tiniest leak. I got back on the roof and re-sealed it and now it is perfect.
Some folk, I believe, also use wood and other stuff to build up to the ribs, but I just used a load of sikaflex and then once the vent was sunk in, cleaned it all off to a nice neat finish.

I have a personel hole on the roof of my mk6 about 2feet x1.5 foot made watertight with a tube of silicon from home bargains one pound and ninety nine pence might be cheaper at the 99 shop though

on the little green vans roof vent however i used some bonded window glue i had leftover even better than the home bargain silicon stuff , very black and sticky though
just dont take a piss when you have some on your fingers

To make up the ribs use upvc trim cut to size, sikaflex or soudal fix it all, to mount a solar panel get the mount brackets and glue with the above to the roof, you don't need to bolt or screw down, make a small wind deflector to go in front of the panel. If you ned to put screws or bolts through, use penny washers and put the above between the washers and roof on the outside and inside. Always measure twice ,cut once.
