Thanks for the reply. The home is located in Birmingham, Alabamastan.. I don't recall the attic having a vapor barrier since it's an older home built before it was a code requirement or best practice. The attic has good ventilation, gable roof vents, and I know that insulation should be pushed back from under the roof's eaves.

You can buy plastic baffles that get stapled to the underside of the roof,
between the rafters, at the eaves, to keep the blown in insulation clear
of the soffit vents. HD and similar have them in the roofing supplies..
They are about 3.5 ft long, but are scored and you can break them in half,
using just one half.

Cardboard stapled on works just a well, too. A piece across the rafter
at each vent. BTDT

Very cool but all the squirrels around there would make short work of the cardboard unless it's treated with something like capsicum. I don't know if the plastic baffles would fare much better since the flying rats love to chew on plastic. I do believe that hardware cloth screen would be necessary to protect the baffles. 8-)


The ventilation baffles are in the attic, on the bottom of the roof
deck, between the rafters, where squirrels should not have access.
And if they do, you have serious problems other than the baffles.
