Melted Snow Patterns on Chicken House Roofs

Somethings are out of site, out of mind.  It isn’t an easy task to climb up in the attic and see what is going on with the distribution of insulation or if there is an attic box not siting just right.  Melted snow patterns can indicate potential areas of poor insulation and house looseness.  This morning we had our first light dusting of snow with some additional snow being predicted for the weekend.  Looking at how the snow melts on a roof can be a good indicator of some potential missed opportunities for conserving on fuel  and being able to maintain consistent temperatures in the house.

Here are few pictures I took this morning.  The first picture shows snow evenly distributed with no bare spots. This is a good indicator that there is minimal leakage of heat around the tunnel inlet curtain, the attic boards are closed, and the insulation is intact. The second picture shows melted snow on the tunnel inlet dog box roof metal.  This indicates there is leakage around the tunnel inlet.  The inlet area may not be fully closed due to the tunnel inlet being poorly sealed.  The third picture shows a melted spot on the roof that is about half way down the dog box.  This would indicate a possible attic door not being closed or that the insulation is not intact.  In this particular instance, the insulation has been compromised in an area just above a heater.  The ceiling material was replaced but the insulation was not and there is an area of the curtain that is not fully meeting up fascia board due to shrinkage.  Identifying these issues and correcting them in a timely manner, will improve performance by improving bird comfort, floor conditions. and reduce fuel usage.
