every morning theres a new batch of these stains .at first , there was one or two but there are now around 8 of them in the living room in just a matter of 5-6 days
its been -20 , -30 celcius here the past few weeks which is alot colder than usual this time of year (northern ontario canada).theres a decent amount of snow on the roof which I plan on shovelling off this week but certainly not an extreme amount
this is our 3rd winter in the home and while -20 , -30 temps are not unusual here it is the first time its been this cold for so long while we've lived here
the roof is in excellent condition -last done in 2004
the only thing I can think of is the few snow storms we've has were accompanied by strong winds and perhaps some snow has come into through the roof vents at either side of the home
I'm going to attach an image -hopefully it works
