How about vibration? Any highways or roads nearby with truck traffic?
Any quarries with blasting? Didn't the northeast recently have a little
earthquakey shakey? I'm always surprised at how vibrations like these
can shake up dem ol bones.
The radial exterior cracks from the window and door headers is typical
stuff; the interior cracks aren't from weathering issues. It's gotta be
vibration or settlement.
Or something else.
Is the new roof structure constructed of trusses or was it stick-framed?
I wouldn't anticipate any thrust issues from trusses....
Ralph, leave that last one alone, OK? I am not desiring to be George
Burns to your Gracie Allen.
