Bubble in roof

[Huntsvillian]

So as per my previous thread, we had a branch fall on the roof and damage the rubber. We had over 2 inches of rain last night and the patches look great. However I noticed that near the one patch there is a bubble.

I never really looked closely at the roof other than when inspecting and cleaning it.

Is a bubble normal? or is it probably air which came in through the small tears and needs pierced, then patched?

I have loose material on my roof, especially around the edges.
If there's no hole, it should be fine. Just monitor.
Seems like where they laid a thin layer of adhesive, you get separation from roof.

What do you think of the grey matter patches? Is it worth putting Lap Sealant around them or is the Grey Matter patches good enough?

I watched this: http://rv101.tv/2012/11/14/quick-easy-rv-roof-repair/


and it shows lap sealant around the membrane but not the grey matter patches.

The patch looks like Eternabond Tape.
I don't put lap sealant around the patch.
If I were going over a curved surface and I had a corner lifting up, then I would apply Dicor Lap Sealant.
If everything is smooth flat and well adhered, no need to add lap sealant.

JMHO,
Doug

Yes it is Eternabond tape. I cleaned then used Acetone to remove grime from the surface. Applied without stretching and used a small roller on it.

I would not think you need it but a small bead on the leading edge may help the wind or debris from tempting it to lift.
