Waterproof sticky back plastic

Hi,

So my conservatory roof is leaking fairly badly from one of the roof windows that is no longer sitting square in the frame.

I’ve delivered a couple of tubes of silicon to all the areas where I think water can possibly get in but it still is.

As a short term bodge, I thought about sticking some sticky back plastic over the whole area.

I’d need a bit about 0.9m x 1.5m.

I’ve had a bit of a google and comes up with lots of sticky back vinyl wraps or films, that are mostly coloured. A clear one would be nice.

Something like this: https://www.stickybackplasticvinylshop.co.uk/1m-x-90cm-wavey-frosted-privacy-glass-effect-sticky-back-plastic-vinyl-film-1695-p.asp

Anyone have any other suggestions please?

We have had a few people ask if our vinyl will botch a roof repair.
It won’t. It will not stick to silicone either.
Get the roof repaired, you will end up with botch on top of botch, and a leaky roof.

Getting the roof repaired is obviously on the cards, but is part of a wider project that wont happen for a little while.

A botch is exactly what I’m looking for!

A sailing shop might be able to provide sail repair film. I’ve got a bit in my kit in case I rip a windsurfing sail. It’s a bit pricey though.
