I would say that 99% of the time when a cable or satellite guy goes into an attic space, the insulation is moved, depressed, brushed out of the way to run cable lines, or whatever.
It is so common that on a recent inspection I made the insulation was as expected and it was so mentioned on the report.
What I did NOT do was take a photo or two. MY BAD.
What had happened was that after moving in the sellers had ceiling fans installed in each of three bedrooms.
To do that the installer created what I called "hiking trails" through the insulation to each spot, and pulled away a crater of insulation to get the support, box and wiring in there.
That's all fine and necessary.
But he NEVER replaced the insulation he disrupted!
DO YOU THINK HE WOULD LEAVE THE INSULATION LIKE THAT IN HIS OWN HOUSE? I BET NOT!
In the photo to the right, one of the three locations, a hole is visible, and even bare drywall! Bare drywall has an R-value of about 1/2!
Somewhat hard to read perhaps, looking at the cardboard rulers all over the attic space the average depth of the insulation is about 10".
A builder's rep met us at the house to assure us that he would be fixing what we found.
But he assured us that they were careful to put in 7.25" of blown-in cellulose, carefully obtaining the desired R-30 this builder's specs desire. He even asked me if I was familiar with cellulose insulation.
Well, yes, since before he was born...
But, this is clearly blown-in fiberglass. It has an R-value of 2.2 per inch. That is an R-value of about 22! To get an R-value of 30 there would need to be 13.5" or so.
So they may have some work to do!
I recommended to my client, and her Realtor, whom you may know, that they ask for photos of the re-insulation job once completed. The builder will likely comply with that request.
My recommendation: even when things are obvious, and old hat, a photo or two might be best! It would spare an additional trip to the house should something become an issue! And then YOUR home inspector won't have to say, "MY BAD!"
