Failing SIPs in climate zone 6
Hello, I am currently working on a punch list project on a home another builder built and sold to my clients.
The house is a kit timber frame with SIPs as roof panels. We are located in Ithaca NY, climate zone 6. The roof panels measure 4 5/8” thick, which is completely under spec’d for this climate zone.
Is there something about SIPs performing differently than conventional framed roofs that could have allowed for such thin roof panels?
Now that the house is being occupied and winter has set in, it is clear that the roof is leaking heat and condensation has began forming on the outside walls at the SIP seams. I wonder how much is forming on the underside of the roof panels throughout the house, it’s just a matter of time until the pine t&g ceiling starts to show signs of moisture.
I am mainly looking for advise and also for recommendations for specialists who would be able to do a through assessment of the building and advise on how to proceed.
