Hi any or all help is appreciated! I am in southern BC in Canada, and we are getting some hotter weather now (still minuses over night but plus 15 C in the day time) and some rain showers. I noticed a small soft spot by my light, a few small bubbling spots, some darker spots and then dried yellow staining in a few different rows. They are varying sizes. We went up in the attic and everything looks bone dry, no sign of any water leaking in the roof, no mold, no wet spots on the wood etc. we couldn’t get a good look under the insulation because it is too deep and fluffy (it’s the grey loose stuff). What do we do?? See photos attached.
