Taking roof off of cabin this weekend to try a remedy condensation issues. Current roof layout from bottom to top is: ceiling, layer of roofing felt, rafters w/insulation, 1x4's, then metal. Plan is to remove 1x4s and put 7/16 OSB decking on top of rafters with layer of 50 wgt felt between metal and OSB.

It will help. However, if there is a way to add insulation, ventilation, or a vapor barrier behind the ceiling, that will help as well.	Todd Miller Isaiah Industries, Inc. 12/30/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/14274/find/
What kind of insulation would you recommend and how would you ventilate?	Guest User 12/31/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/14275/find/
Ventilation requires intake and exhaust vents. Intake vents usually at the eaves and exhaust at the ridge. Great source of info is www.airvent.com Insulation I was thinking blown in or batt. You could also look into polyicyene which would reduce the need for ventilation.
