Forgive me for my questions. Why would I tear any old stuff out? Most of what is present is pink rolled insulation. It just seems like they didn't get every area and alot of it looks to be pulled away like they did wiring etc and didn't put it back.
It's a pretty big attic. I'm not sure I would want to tackle removing it all or not. In the last 3 years we've replaced the roof, all of the original wood siding (bad shape), completely renovated an outbuilding/guest house, and are now finishing up an addition. Maybe if I take a year off I'll feel like tackling it.
I still need to replace the old copper pipes with pex (have had to fix 3 leaks the last 2 years), the breaker boxes need to be redone, and more.
It's hard to decide what to do next. My electric bill is crazy high. We pulled down the original siding, ship lap, and put insulation in the walls as there was none, plywood sheathing, wrap, and hardiboard siding. We replaced every window except 4 on the front because my wife likes them with the wavy glass. I'm honestly not sure any helped the electric bill.
