Roll on or paint on roof sealant for many small holes?

[shburr]

Hi everyone... Hoping someone can give me the benefit of their experience. We bought a used 24' yurt and now, unpacking it, find that the roof is full of pinholes... We're looking at the elastomeric options but all the manufacturers are telling me their product won't adhere to vinyl. I'm wondering if anyone has had luck with Gacoroof or another product? And if they can offer some guidance? Thanks!

Can't answer your question. Sorry. If you need in that yurt like right now, get a cheap plastic tarp up there, until you get a solution figured out.

I'm sure you've come up with something by now. However, if by some chance you didn't......read post #17 in this thread. It is my experience using Gaco silicone paint...on vinyl.



For all others interested in this thread, after 9 years...here's an update: The silicone does not hold up well to abrasion. The ropes that help hold my roof panels on have rubbed the silicone off. We have also lost some silicone on the roof from slabs of snow sliding off. OTHERWISE...this stuff appears to be as intact and useful as it was when I applied it.



For reference, we're in the mountains which normally gets 7' of snow/yr (we got 10' this yr). The yurt is on a south facing slope getting full sun every day. It doesn't look new...but I don't care. It doesn't look shabby.



At some point, I will have to repaint the roof. As of right now though, I've seen nothing that makes me think I'll have to do this any time soon. Even if I do get a small leak, the water would just run down the bubble wrap

insulation

and end up outside anyway.



In summary, the Gaco silicone far exceeded my expectations and was many times less $ than a new cover. My cover is now 36 years old and I don't see why I couldn't squeeze 20 more out of it with another application at some point.

UPDATE


Last month, I noticed a drip inside our yurt during a medium rain. Then I noticed another, and another, and so forth. I looked behind the insulation and saw countless pin holes in the cover.


So, the silicone paint has reached its end of life for our roof. I suspect some leaks have gone undetected for a while...a year, two...I don't know. Regardless, I think this GACO paint is an excellent way to squeeze more life from a vinyl cover. It's ~$250 for the roof compared to a few thousand for a new cover which, might not last much longer.


I will be repainting again some time in 2024, hoping to get another 7-9 years from my roof.
