When walking through a house, ceilings that bulge downward bulge for a reason.
In this case there were new light fixtures installed in the bathroom ceiling. A new fan was also installed. And the ceiling nearby bulged downward dramatically. Knowing what I was seeing I broke out Mighty Mo.
The thermal camera showed what I suspected might be the case.
You can even see the bulging drywall in the thermal image!
This is early in the morning, and it is not hot yet outdoors, yet even in the morning sun the attic space is beginning to heat up quite a bit.
One light and the HVAC register can be seen just to the lower left of center. The AC is running, which accounts for the cooler temperature at that point.
The new fan is downward and to the left of all that.
You already know what is accounting for the warm rectangle in the middle of the thermal image - a lack of insulation.
Looking at that same location from the attic space the original HVAC duct work can be seen as the large, foil-covered tube running to the area without insulation.
The smaller, white fan tubing can also be seen running upward to exit the roof.
An area devoid of insulation is typical of unprofessional installations such as this one.
High piles of insulation were pushed off of the area that was worked on, without being repositioned back into its place. Such a large area without insulation will definitely affect the comfort of that bathroom summer and winter. Particularly in winter!
My recommendation: in this case it did not take a thermal image to see that there was an issue with the bathroom ceiling. But the result of the unprofessional work was surely demonstrated by a thermal image, and definitively. Improper work has consequences. While it might be a good idea to add new lighting to a bathroom, it is a better idea to do so professionally. And then not sell the unprofessional work to someone else. AFTER ALL, WHO WANTS TO BUY A HOUSE WITH UNPROFESSIONAL WORK? I bet this seller would not want to... says he, with sarcasm dripping from his lips.
