| Would it be better to save thermal imaging re heat loss until the snow has gone to avoid reflection issues? ALSO, do you think thermal imaging for heat loss is best done in the hours of darkness. Thanks all ( Bit of a novice here as you may have guessed!) |

Snow has a very high emissivity, and is a diffuse reflector so it doesn't reflect too much in the infrared (of course it is very reflective in the visible).
You have to remember that snow also insulates as well, so heat loss will not be as apparent as if the roof surfaces are free of snow.
Evening hours are generally preferred because the effects of solar absorption and reflection are minimized. |
