Does anyone know how to elimatinate creaking noises in the attic. Especially when it is real windy out. It loud enough to wake you up at night.

Now thats a lot of ifs ifs Have you been up there and see where the noise is comeing from? If a gable home any 45o braces on the end walls could help. From the ridge board to the ceiling rafters.

Is this an attic as originally constructed, or does it show signs of modification? It's tough to provide a flow chart for your situation, because we have zero information other than confirmation you have an attic.

Let's assume the roof is rafters, not trusses. In that case we expect to see collar beams every third rafter pair. A collar beam is a horizontal crosspiece about one third of the way down, from the ridge.

Take a good look at those collar beams. Most likely 1x6, but other lumber has been used as well. Are the connection points secure? Are all the collar beams present?

What about the connection points of rafter to wall? Is there any evidence of movement or shifting?

Where do you think the noise is emanating? Would you consider staying up in the attic and listening for the sounds?

What is the roof style? I am thinking it's a Gambrel (barn) roof, since most other styles are simply triangles (and triangles are quite rigid).

If not Gambrel, the roof could still have construction that isn't completely triangulated. Take some time and memorize your rafter system(s). Where are the less-than-rigid connections?

If it's Gambrel, you need to plan how to stiffen the connections. A lot depends on how the connections are made; lapped or gusseted.

What is the current usage of attic, and what do you plan for the attic, in the future?
