Deck making noise ….?

[luberhill]

We are renting a house while looking for one to buy .

 Beautiful two story 2300 sf home .

Has two wood decks on the back .

A couple times now I have heard what sounds like a softball dropping on the deck.

  Is it the cold causing this ?

I would not be surprised.  Over the years, when it gets this cold, there have been times our deck sounded like a rifle shot going off.
