Roofing insulation creates moisture by the beam inside
We are in Hawaii. The new building code requires insulation (roof) so we did it.
Unfortunately, after a while, especially the temperature changes from cold in the morning to hot in the afternoon, the ceiling starts to sweat around the beam, all choking moisture out, water (clear) drops all over our floor. Now the painting on the ceiling is like a wet stain ceiling. We have ventilation, I don't know what causes this. The strange fact is Hawaii's local roofers can not figure out what is wrong. Anybody have an idea? I took some pictures also. Thanks! |

Hi, should the inside of a cinder block chimney have some type of insulation? The chimney measures 16x32 inches on the inside with 7x11 inch clay tile liner (running pretty much up the center) and a sheet metal chimney cap. Also the chimney is 13 feet tall to the top of the wood burner. Thanks
