You probably have a ridge-vent with a filter in it. Filters trap moisture, restrict air flow and clog with dirt. Ridge-vents made without an exterior baffle design don't work very well. You must have a ridge-vent with an exterior baffle design in order to move the air out of the attic. 99% of all moisture problems in the attic, as well as snow in through the roof vent, is caused by lack of proper soffit venting. Soffit vents on existing homes become clogged with dirt, paint etc. many time there simply aren't enough vents installed in the first place. This is the number one cause of heat and moisture build up in the attic. Go to www.lomanco.com and you can learn all about how to properly ventilate |
