Found a leak. (The bubble thing over the shower big time) When looking to find what to use saw stuff for rubber, full coatings. It is on a 2002 Four winds. It looks like the sealing stuff now is around screw heads, edges of protruding things like stack, antenna.

Is it the mounting seam leaking or the bubble itself some where due to a crack.??. Mine cracked after 25 years so I repaired it,, then covered it with a clear coating..>>>

That is typically just caulking and can be removed as needed with a putty knife or any plastic blade like tool,, then I use a good brand of polyurethane sealant available at Home Depot .>>>Dan

Looking on Amazon I see Dicor has "self leveling" and non sag. I would think the self would be what I need. Home depot or anything else is 1.5 hours away.

Don' t use the Home Depot sealants. Either Dicor (self leveling for horizontal surfaces) or Geocell. I am liking the Geocell but the Dicor is good stuff and easier to remove and reseal in the future.

X2 on the Dicor self leveling. Get 2 tubes, while you are waiting on Amazon to arrive, get up there with a soft brush, bucket of dawn soapy water. Scrub lightly all seals around all the objects, and the whole roof. Rinse, let dry. Then take your 2 tubes up and go around everything, antenna, side seams etc. I recently had to replace my skylight (bubble) as a limb hit it. On a 20 year old roof, I would not try and fix anything, simply clean and coat over.

Good advice from the pasters above. If you need to know your roof mtl for any future work, this video offers good advice.

Good luck on the repair ....... and safe travels.

It looks like there is another cover in the shower and it all ears to have debris of some sort on it. Appears to have been leaking awhile. After getting up there this morning it is rubber. Attached some pics.

With a 2002 it is pretty sure to be an EDPM roof. The pictures of the bathroom skylight do show that it is time to replace the caulking. Most people recommend that you examine the roof and all caulking at least annually and add or replace caulking as needed. Like several others in this thread, I use Dicor self leveling on all roof penetrations.

4 tubes ordered, get up there and start removing after the dew burns off. Decided to remove after looking up at the ceiling in the shower so I can inspect/repair that too.

The Dicor Lap Sealant will work for seam sealing whether the roof is EPDM or TPO. Or even fiberglass or aluminum, for that matter.

As for Self-level vs Non-sag, you will have to judge for your self. The Self-level type will run on even a slight downslope. It looks to be clinging fine, but 30 minutes later it will have run down (leveled out). Most skylights have a flange around the edges so the seam is flat against the roofand the self-level is the best choice. However, if the skylight has cracked upwards a bit at the sides, you may need to seal that as well. That crack may require a non-sag sealant. It doesn't have to be Dicor for that part, though.

Start out by removing all the caulk then all the screws. Carefully try to break the seal away from the roof. Clean up those areas. Then reinstall with new caulk, SS screws. You may need to go either longer screws or bigger diameter. Do not over torque them. If you do, you’re liable to crack the flange. Just work your way around the flange tightening the screws just a little. Only go far enough so that the caulk oozes out a little

I wouldn't try to remove that old skylight unless I had a replacement in hand. It is very likely brittle and will crack or shatter, plus it's a lot of work for little gain. I'd just clean up the old sealant and re-seal as needed.

Not REAL bad. Had already done before I read or would have been more careful. But there was a lot of moisture in it and rusted screws.
