Same issue. Contractors have quoted me 2k to blow in and seal attic spaces. You can rent a machine at HD and do it yourself for under 500. This winter has been mild so haven't affected us much. But definitely get it done by spring or you will be baking first heat wave in the summer.

Is the rental machine blown in insulation or foam insulation?

Rental machine is for blown it.

Before you install insulation, you should also figure out your attic venting situation. Without proper venting condensation will build up and cause mold.

I just did blow in insulation at my house, around 900sqft worth of roof, because of the slope we couldn’t hit the same r value throughout, but used around 30 bails of cellulose insulation. Was around $600. Venting, installed by a roofer will be another $700.

Blow in foam. Mine is a sloped shingle roof. But will probably wait till spring to get it done. No rush now.
