Notice moisture spots on ceilings or damp insulation? Talk to us. We see it all the time! We trace the problem to its source and provide solutions to eliminate the problem and prevent it from reoccurring. In winter stagnant air can lead to moisture build up. Your attic requires good cross-ventilation (intake and exhaust) to keep air from stagnating. Moisture can wreak havoc on your roof and adjoining structures. In summer stagnant air can increase attic temperatures that cause you to run your air conditioner more, consuming more energy and costing you more.
