leaky roof

I did a temp fix using clear silicone cocking while on the road worked like a charm, and being lazy i havent fixed it yet after 5 years

We were in the trailer last weekend when it started pouring rain. Water started dripping into the trailer around both skylights. I went up on the roof after and I can see how the roof sealant is cracked around the skylights. Should I spend the time to remove the old product before attempting to seal the leaks or just paint more sealant around the skylights?

Go to http://www.dicor.com/ and all will be answered straight from the horses mouth.

If the original sealant looks good, and is fastened solid, I would clean up the old sealant in the cracked areas. I have used glass cleaner with ammonia with good results. After cleaner is dry, cover the cracks with self leveling dicor.

Good luck, whatever way you choose,

X2. I checked the sealing around my roof vents recently and found some minor cracking (actually just 2 cracke that didn't appear very deep). The rest of the sealant looked very good. I filled the cracks with new Dicor self-leveling sealant and all is well. When I have more time I'll probably apply Eternabond since I have quite a large roll of it left from a previous application.

Definitely remove the old sealant first. I notice that on any tube of Dicor sealant the preparation instructions always say to carefully remove the old sealant. I wish I knew how that was done because that sealant seems to engage in a tug of war with the EPDM membrane anytime I've tried to remove it. :M Good luck.

Depends if you want to fix it right or just fix it for now. Best answer would be to remove all the old. Then remove the roof vents. Apply butyl tape under the roof vents when reinstalling them them apply the self level caulk or the eterna-bond tape. Then it will be fixed right.

I would think that the right way to do it would be to remove the old and replace with new. the easy way to do it would be to slop something over the old.
