5 years ago I removed my old asphalt roof down to black paper and plywood and installed metal roof.
Then professionals blown fluffy insulation about a 1 meter high. This winter I checked my attic and I found frost build up on roof plywood and trusses which will change to water eventually. I don't want to loose my wooden roof structure . Do I have to do some insulation under metal and I don't work from attic where is full of insulation and small enter through the bedroom closet. Thanks,
Yurek B.

There is vent as long as the roof at the top ,that special type of gasket with screen sections and from one side of the roof,typical sections with
small slots .

Thank you for your post. As I am sure you are aware, what you have is not a typicval residential metal roof. You have insulated panels and, while the insulation deadens some sound, these materials can conduct sound as well. Adding an airspace or additional insulation would be your best ways to remedy any objectionable sound.

Yurek, at first blush it sounds like you need ventilation in your attic space. Is there any opportunity to add that? You'd need bothy intake and exhaust vents of course.

I installed a 3 inch aluminum skinned insulated roof using interlocking roof panels which worked well except
For the rain noise that at times is deafening. Are there any solutions that you could offer to help .

Insulation without air sealing will still allow most of the warm moist air to hit the cold framing.
Now that you have insulated, less of the heat is getting to the roof deck so it is colder and the condensation issue is going to be worse.
You need to air seal the attic floor as well as get the proper ventilation in that attic.

What about intake ventilation?
One without the other does not work at all.
