My 4 year old home is very underventilated. Lots of eaves vent intake but
only three small mushroom type roof vents over 2500 sqft of attic floor.
I'm considering ridge vents.

I was told that if the design of my homes ventalition is below some
"standard" and bringing it up to standard meets some energy efficiency
metric, either the government or my insurance company would cover part or
all of the upgrade.

This is in Houston Texas.

Anyone else heard of this or is it complete BS?
