The snow is not affected by the heated house meaning that the attic floor is reasonably airtight and insulation is sufficient.
If snow stays on roof does that mean good insulation.
Many homeowners report that their homes feel warmer after a good snow as long as there s enough insulation in the attic floor to keep that heat inside and the snow on the roof.
If your roof gets a decent amount of snow on it make sure it s not melting in specific spots.
This house is good news and bad news.
According to one anecdotal source a snowfall that measures about 0 07 inches in density or seven percent water volume has about the same insulation value as a standard batt of fiberglass insulation with an r value of 18.
The good news is that it is beautifully restored and from the 18th century but the bad news is the owner is paying to melt the snow on his roof.
