I have a 20' x24' ft sunroom with a sloped ceing 14 ft high at the highest point. Ther is no attic over this room, justing a woodensheeted ceiling and the insulated roof. My roof is sweating under the shingles. Moistures is constantly running out from under the shingles in one area and onto the deck below. Anysuggestions on how to fix this?
you need to find out where this excess moisture is coming from first. Then get this fixed and the roof may be fine. do you have a new slab on grade floor? A lot of plants getting watered but no exhaust ventilation? Are there recessing lights in the ceiling? As mentioned... location? these issues are different for different climate zones.
