New Construction Roof Makes Noise

Our Answer

A couple of things come to mind: First, I find it unlikely that your builder is qualified to make such a structural analysis.  He’s essentially commenting on the impact of wind and weather on a structure, which is something only a licensed structural engineer or licensed architect has the education to back up. 
I recommend a few things: Document your concerns to the builder in writing. Second, request the builder hire the structural engineer or licensed architect of your choice to inspect your property and provide a written report as to the cause and cure – if required – of the problem you’re experiencing.  Third, send the letter to your homeowners warranty company, documenting the problem, the history, and the dates observed so they can begin a claim against the warranty (should that become necessary).  Last, consult an attorney for additional actions you may need to take to protect yourself.  Roofs that are properly constructed don’t creak to the extent you're describing.  The fact that yours is making noise is likely an indication of a bigger problem you want to avoid.
