My house was built in 1998, and people seem to have tramped around in the attic a lot, perhaps when the original owner was adding a lot of storage up there. In any case, I can see the bottom chord of the roof trusses in places, and those are 4” high. I think my heating and cooling bill isn’t too bad, but more insulation will definitely reduce heat transfer, whether or not it is cost effective. Also, I have a guest room that is always much hotter than the rest of the house in the day. I wonder if it was ever insulated at all. I need to get up in the attic and check. I thought it was morning sun, but I put up a big shutter that keeps the sun off, but the room is still hot.
