Skylight/roof repair

Well then you may be interested in This Recent Thread about Flex Seal :B

In rainy Oregon UV may not be a problem..

So, using the Dicor you covered 6 inches, the same girth as you did with flexseal?
Did you dicore over the screws too?
I can't imagine Dicore Lap sealant not working. I suspect user error, so curious what your method was.
Dicore is good for RVs since it is a good idea to re-do this every few years anyway. Dicore is easy to remove and re-apply.
Sounds like by a few years the flexseal will deteriorate so can be cleaned away with a small wisk broom at least.

Use Henry 887 instead.

Let us know how it's holding up in 6 or 8 months.

I covered the area thoroughly I know what I am doing, I spent 50 years in commercial construction.
The issue with the Dicor for this job in my opinion is the small hairline cracks and fissures that happen after application and I doesn't "flow" into those small spaces like a liquid.
Thanks for your upbeat post.

I am always hesitant to post an experience I have had that others may benefit from on this forum.
There are always those who are more experienced and have different opinions, and are always more than willing to share them.
This worked for me I thought I would share.
I am probably better off being an observer and not posting.

If you had a leak at one time (even if it is sealed now with whatever method) you still may have a ticking time bomb. What I mean is that depending on how much moisture got in, there could be potential for damage.

When I had my campers, I would perform religious maintenance on them. Even with that regiment schedule, there was an instance where water got in near my skylight... I think it might have been from the adjacent vent.

in addition to removing and resealing with self leveling roof sealant made for RV's I ended up replacing the vent and skylight as there was more deterioration than I could have imagined (and all this even with pretty strict inspection and upkeep... the potential is there.) I also had to perform minor repair of the roof frame as well.

I guess what I am saying is even though there is no leak at this time, keep an eye on possible future compromised roof structure.

I'm so sorry, jesseannie. Civility is at an all-time low these days.

I wish I knew the cure.

However, I don't think the solution is for good people to withdraw.

I wish that more people would heed Thumper's mom's advice. And along those lines, a lot of people's mothers would be disappointed if they saw how their kids were behaving online.

Sorry to go slightly off topic, but if the skylight itself has a small crack, what product would work on that?

I would use a good caulk or sealnat.
I used Quad Max on my camper:

When I did maintenance one time before my skylight overhaul repair, I tried Eterna-Bond on the flat flanges where it meets the roof. I did not have good luck with that method. I thoroughly cleaned the surface as that is very important, but it did not stick which prompted me to completely remove the EB (not fun on the portion of the roof where it DID adhere.

I have read where others have used EB on the skylight with better results than me. I guess you could try it on a sample area otherwise another method might need to be used.
