Attic Insulation on the day: sealing, depth and cleanup
Middle Tennessee is climate zone 4, where the recommended attic value is roughly R-38 to R-49. A great many Nashville attics still hold the R-19 that was normal when the house was built, which is somewhere around half of what it should be.
Air sealing comes first, always. Blown insulation does not stop air movement — it filters it. Laying it over unsealed top plates and penetrations hides the leaks while they carry on costing you exactly what they did before.
Depth markers are the honesty test. They cost almost nothing, they let anyone with a torch check the work months later, and their absence is usually a sign the depth was uneven to begin with.
Here the payback is mostly on cooling rather than heating, which is the opposite of how insulation is usually sold. Our summers are long and our winters are short, and an under-insulated attic in August is punishing.

FAQ
Attic Insulation: what homeowners want to know
How much attic insulation should a Nashville house have?
About R-38 to R-49, which is roughly twelve to sixteen inches of blown fiberglass or cellulose. Most older houses here have half that or less, and it is the single most cost-effective energy improvement most of them can make. The depth is marked with rulers stapled to the rafters so the coverage can be seen and checked, and it is measured before and after.
Should I add to my existing attic insulation or replace it?
Add to it, if what is there is dry, clean and not compressed — new insulation goes over old. Replace it if it is wet, moldy, rodent-damaged or so compacted that it is doing little. Either way the attic is air-sealed first, because insulation slows heat and does nothing about the air moving through the gaps around it.
