Still in the attic.

Well you finished the roof inspection and checked out the ductwork. Hopefully you found all to be in good order and not in need of attention. What's next? A cold beverage? Nope. Look around and see what spent the winter up there and initiate eviction proceedings. Look for disturbed insulation,rat droppings,nut shells,snakeskins and any other evidence that you are not alone. Have a look at any exposed wiring and junction boxes to be sure they haven't been chewed by vermin or children. And finally see if you need to rearrange or replace any insulation.
