We recently moved to Northern BC Canada. Just git through
-40 degrees celcius weather and today it is 2 degrees celcius. There islots of water coming in. This didn't happen when it rai ed. We discovered there is no tar paper under tin.
My husband thinks it it is the condensation dripping through any where possible. My main concern it is drippingg near a 100 amp breaker box. Terrifying. Since it is holidays we are not able to get roof fixed until next week. Any meantime suggestions ?

Please describe the construction of your roof and the interior wall coverings to give us an idea of what you have going on.

Sounds like lots of condensation may have frozen and all started dripping at once when it thawed. Did you do anything to make lots of moisture, e.g. do you have a ventless heater? Or water may have gotten into a seam and expanded when it froze, creating a leak where there was none.
Is the tin visible from inside or is there wood decking under it?

Do a makeshift cover over the elec box?
Btw, is this grid power or genny or solar or what? The grid power, if done to code, is likely properly grounded, the others are iffy. With iffy and no ground fault outlets could be an electrocution hazard with a wet floor and plugging stuff in/out or even running a device.

You should have an underlayment and 30# felt or a water proof membrane under the metal.
Heat on one side and cold on the other, you will get heavy sweating.

Decking underneath. We just have a blaze king going. We did however go from -40 degrees celcius and 3 foot of snow to +2 in one day !! Wow !!

Yes it has stopped now but was alarming. We managed to get ahold of a contractor friend..funny he pwned the cabin 10 years ago !! He is coming by next week to put the membrane in and put tin back on. We have a tiny cabin thankfully. Jeez heh!!

What kind of insulation do you have between the living space and metal roofing?

This isnt a common issue that comes up here. I cant help but think that there is some substantial issue(s) in the build design/quality.
If the 'pink stuff' is rigid styro you will be better off than if it is pink fiberglass insul that is now soaked and needs to be replaced.
Just where is the insulation, between the rafters, above rafters but sandwiched by the roof deck, or is there no roof deck, just the metal on top of the insul?
Even if styro that you can leave in place it may be needing a proper vapor barrier on the 'warm side' to keep that condensation from going above it and freezing on the cold side, then melting and raining down.
I dont envy you having to pop the top on your structure in dead of winter!
