Our house makes a rather large BOOM when it is really cold outside. It actually happens about 1-5 times a night & it sounds like something is hitting the back of our house very very hard. I'm sure that it is the 2nd story wood deck against the house.
I have tried both tightening and loosening the lag bolts that hold it to the house but it doesn't help. The deck is screwed together. The only benifit that I get from this is that I know when the temperature gets below 17 degrees.
