If Snow Stays On Roof Does That Mean Good Insulation
This house is good news and bad news.
If snow stays on roof does that mean good insulation. The best snowstorm for these observations will. If your roof gets a decent amount of snow on it make sure it s not melting in specific spots. If your attic insulation is good the snow will stay on for a long while and actually will add insulation to the roof since snow is an insulator. The snow is not affected by the heated house meaning that the attic floor is reasonably airtight and insulation is sufficient.
That means there s heat loss likely due to poor insulation and or ventilation in the attic.
