Legend has it that the Inuit have many different words to describe snow

[Don Corleone]

Warmer weather can mean changed weather patterns and thus local anomalies. For example changes in the Labrador stream would have considerble impact on your local climate, like the Gulf stream does for us.

Anyway, could you send those 30 cm snow over? We seems to have gotten most of our snow misplaced.

Hosa, how common is that with morons who doesn't know how a roof is supposed to look like with heavy winter climate? I mean needing to showel the roof?

You are more than welcome to them, and any others slated for my neck of the woods, my friend. Now, if I could just get handy-dandy weather relocator up and running, it should be over to Gothenburg, or wherever you reside, pronto.

Was your question to Hosa about designing a roof that can bear the load of full snow on it? Well, funny thing about that... they've had to change the building codes. You see, prior to the 80s, we didn't insulate our houses so well. As heat escaped through the roof, it would melt the snow or cause it to slide off, and thus earlier codes weren't particularly rigorous.

With the advent of better insulation came the cumulative affect of unmelted snow laying on an frigid mass, never likely to melt, or slide. So if the builder cut corners, saying "the roof will last through any one storm", but then the homeowner insulated, the roof may not be able to tolerate cumulative snow weight through the course of the winter.

No kidding, even here in Maine and New Hampshire, where we get a LOT of snow, older roofs collapsing under the weight of snow can be an issue. Uncommon, but not unheard of.
