I think the main priority for the upcoming rain storm is to verify that the roof drain is free of any leaves, and that the mesh cage that is supposed to keep debris out is properly installed over the drain opening. That was the problem with our major leaks last time: the mesh cage had been dislodged, leaves and trash blocked the drain, and we wound up with a foot of water on the roof, which likely overtopped the vents underneath the skylights.
We should also put tarps over our most valuable equipment just in case - especially the bioreactor, HPLC, UV spec, and plate reader.
If anybody has time to do some work on the roof today, we can also try to close some of the gaps in the roof coating itself, but we would likely need to use the fast-drying black tar-like stuff that dries fast, rather than the more environmentally friendly latex based coating that takes a day or two to dry.
Ideally we should have done that *before* the rains hit, but I think we were a bit caught off-guard with this unusually early rain storm.
The skylight seals in my estimate are of secondary importance compared to the leaks in the roof coating. They still have the same seal they were installed with ~8-9 years ago. It is definitely worth re-sealing them, but I think we were getting far more water coming through roof leaks than leaking around the panes of the skylights.
