We are getting ready to put a new roof on our old rancher and will be having other (major) remodeling done.
Our existing attic insulation is a combination of 50-year-old, loose insulation which looks something like shredded wood. It reminds me of mulch. On top of this stuff in some areas, someone added bats of pink insulation (with paper). I'm not sure if the additional insulation was properly installed. It looks as though it was just tossed around in some parts of the attic
It's a mess!
Should we have all the old insulation removed and install all new? Would this be much more costly?
