Bubbles starting to appear in roof sealant

Hi everyone,

I've had a 2021 Roo 233S for 8 months now. I started noticing a few bubbles raising during the day and going down when the temperature cools down.

I assume the sealant is self-levelling, I don't know if it makes a difference.

Looks like there have been air bubbles when the sealant was applied during manufacturing, which are heating up and expanding.

I'm tempted to cut the top of one, verify my assumption and fill the space with sealant.

Note these are only occurring on the sides facing north, receiving most sunlight.

We live in New Zealand, and while the sun is quite brutal during summer, surely it isn't worst than many places in the US, where these RVs are also present.

What do you think?

Welcome to the forum its a great place to get your questions answered. I think you are on the right path. I think I would use a hypodermic needle instead of cutting and see if you can extract the allow the bubble to collapse if it does seal the hole and see if it the fix works then proceed. JMHO
