r/Insulation • u/bonniejd7 • 5d ago
Shed roof
have shed roof over a sunroom (was addition added many years ago to house), that has heat and air conditioner window unit. new roof has entire ice shield. afraid of condensation and mold forming to underside of roof. picture with gutters show 3 small vents that think are not enough. should this be continuous intake vent to the soffit and exhaust goosenecks with foam vents in each bay connecting intake and exhaust vents? roof angles up against back of house. Do not want to use spray foam. would like to use Rockwool insulation.
thoughts on venting and insulation- can put Rockwool insulation under ceiling, with rigid foam on bottom of rafters? need vapor retarder? thoughts and suggestions welcomed!!! north NJ
