Leaky Roof Vent Repair on Fiat Hymer B644

Our roof vent suddenly started leaking. Both the one at the front and one at the rear started leaking at the same time - very odd.
This video shows how to redo the seal using the proper sealant a mastic sealant strip which is better to use than silicon, I especially on an aluminium roof.
I am a huge fan of silicone but in the video, you can see that the seal has failed. With a mastic tape - this stuff stays flexible and seals for many many years and is very resistant to UV.

I have included a list of affiliate links to make it a bit easier to find whats requires for the job.

Mastic Tape - I used the 32mm and cut it in half, 16mm was plenty for the job - https://amzn.to/2YgSkAm

Paint Scraper - these can be useful for getting that stubborn silicone off - https://amzn.to/336lfG9

WD40 - great for taking off silicone among other things - always handy - https://amzn.to/31m6UUz

Wonder wipes - these are great but not the best for silicone removal, useful for a lot of other jobs and I always have a pack - https://amzn.to/2YogwRq

If you decide to go ahead and reseal a roof hatch good luck, hope it all goes well.
