Installed roofing on deck house last year customer calls saying there is a leak.
No problems with the install no leak from roof. However we installed 4in iso board when he had 1/2in before. I think that its a condensation problem, maybe too well insuated?

If it wouldnt be too much to ask, could you answer a couple more questions?

1. Strapping could mean a couple of different things in roofing, so could you please clarify what you did, what you meant by strapping?

2. If the insulation is on top of the roof deck, it is considered a warm assembly. Is this what you meant, or did you mean a cold applied system?

3. Is there cathedral ceiling?
