Is Uneven Snow Melt on Roof a Sign of a Problem
I am a long time lurker on these forums. For a very long time I wanted to build a passive house here in upstate NY, but I ended up buying a a brand new construction house in March of 2020. It is supposed to be well insulated, although not anywhere close to passive house levels. I have noticed some uneven snow melt on the roof and it has me concerned something is not right with the insulation details, or the HVAC system. I am attaching 2 pictures from today of this, and I noticed it a couple times in the spring after we moved in. It is always in this area the problem occurs.
In my opinion on a roof that is facing the same direction, with no difference in shading, or slope changes the snow melt should be pretty much uniform if the insulation levels are the same. There is clearly some consistent snow melts in a couple areas of the roof.
What are your thoughts? Do you think there is a problem here?
