My husband and I currently live in a Clayton double-wide home. The house is 3 years old. Our bedroom wall is an exterior wall and in the summer, it seems that when the sun hits the siding, it bangs and cracks at even intervals (like every second to 2 seconds) for about 15 minutes. In the winter, it seems to do it when the heat is on. It seems to be coming from the exterior wall and the ceiling. This morning it sounded as if someone was stomping on the roof. I'm pretty sure something is adjusting to the temperature changes, but what? and why is it so loud? I have never heard anything like that in a house before! I am rarely at home this late in the morning, but on the weekends when I'm trying to sleep in, I get interrupted by this constant noise! Is there anything we can do? If it weren't set up as the master bedroom with an attached bathroom, I might just change rooms! Thanks for your help!
