Heat Streak

Was severely crippled by the latest attic insulation work.

The red square is/was the location of the heat streak (i.e. the area where heat escaped into the attic and continually melted condensation (of any kind) from the roof). When you expand the picture, you can see the area in the red square is completely white and that's a good.

The blue square is in the rafter next to the heat streak. You can see there's some evidence of melting there. This is to be expected as I have not completed the insulation work in that area. Currently there's only a single (pieced together at best) piece of insulation there.

The green square identifies another area of melt. Though somewhat perplexing, I think it's related to the vent pipe in that rafter space. The vent pipe prevented me from properly filling the space with insulation. Maybe I'll go back and try harder.

The other perplexing area of melt is the bottom right hand corner of the bathroom vent furthest to the left (I know. I'm totally OCD about this). I'd expect the snow to melt first around the metal vents through the day being they are metal, black and absorb a lot of heat, but this picture was taken in the morning after the nighttime snow. I could also expect a certain amount of heat to escape up through the vent from the bathroom and cause some kind of uniform melt around the metal cap, but this isn't uniform. To avoid being too anal about all this, I'll probably take a quick look the next time I'm in the attic, fix what's obvious, or leave it alone.
