Back in April we re-roofed our house that we purchased in February (ins company requirement to re-roof).  The house is 23 yrs old.  We have 2 skylights, both of which were leaking, not into the house but into the OSB of the SIP panels.  The roofing company replaced both sections with full 4x8 sheets of OSB.  I'm not really sure why they replaced with a full sheet.  Both rotted areas were somewhere around 4x4, or a little less.  Anyway, they only nailed the replacement OSB to the splines and didn't glue.  Our panels are about 22 feet long.  My question is this -- should I call them back to have them remove the shingles and go back and glue the OSB replacement piece in addition to nailing?  We live in Wisconsin so there will be snow load to deal with.  I'd rather pay a little now to do it right than have an issue down the road with deflection. 

Additionally, one of the new skylights (we replaced both with new Velux skylights) has condensation and actually drips on the floor when the outside temps are in the low 30's.  Any suggestions to fix this?

Thanks for the help.
