More on SIP Rot
Many thanks for all that has been posted about SIP rot and how to avoid it, but my timber frame home was built 22 years ago, and the problem is now appearing. I need cost effective advice about how to fix it.
The panels are 4 inch with OSB exterior and blueboard interior. They were installed with seams following the roof joist beams. Drill and fill, nothing else to seal them.
now they are weeping brown water and decay down my siding and some interiorly as well.
Ok. I can fix the exterior with 2x strapping and new sheathing, etc. But from what I am reading, it is the interior moisture that is causing the issue. How do I retro-seal these now?
