Last evening we kept hearing loud "thuds" and "creaking" sounds coming from our roof...

It continued thru the night, waking us more than once.

Finally, this morning, my wife convinced me to pull out the ladder from the garage so I could check out the attic.

All looked fine, but GEEZ-oh-PETE! It really seemed like the roof was caving in. 15* below actual is even making our house complain. :)
