Loveland Roofing: Article About Attic Ventilation
For most homeowners, the attic isn't a part of the house they spend much time thinking about. However, attic ventilation is actually an important issue that warrants some attention and effort. Without proper ventilation to keep the air fresh and moisture levels controlled, damage can occur to both your roof as well as the rest of your home. A Loveland roofing contractor can inspect your attic and determine if it's receiving adequate ventilation.
Moisture-related problems are the most common consequence of poor attic ventilation. Temperature changes in the house cause condensation to form; appliances that vent into the attic are another source of moisture. Even precipitation that seeps in from outdoors can add to moisture problems. When moisture accumulates inside an attic, it creates the perfect breeding ground for mold and mildew. The damp environment combined with mold and mildew growth can damage possessions stored in your attic. Mildew and mold that circulate through the indoor air can cause a host of respiratory problems for people living in the house.
Moisture in the attic can also damage shingles and wood. This warping and rotting will not only allow even more moisture to come in when it rains or snows, but it also can result in eventual structural damage to the home. Additionally, if moisture seeps into the insulation, the insulation will need to be replaced. These moisture-related problems are serious, and require expensive repairs.

Poor ventilation can even result in higher energy bills. Hot air rises, and if your attic isn't adequately ventilated, the heated air will get trapped in it. This hot air lingering directly above your living space can put a strain on your air conditioning system, which will have to work harder to cool your home. If the hot air can be released from the attic through a good ventilation system, your air conditioner will be able to cool your home more efficiently.
Your contractor can determine the best ventilation system for your attic. Rafter vents, soffit vents and ridge vents can all help to keep air flowing through your attic and control moisture levels.
Some homeowners avoid ventilating their attic because they're afraid that they may be allowing cold air to enter the house. This fear has no factual basis: A home's living space is insulated at the floor of the attic. The attic functions like a separate space, and ventilating it will not make your house colder. Good attic ventilation should be a priority for all homeowners. Taking the time to make sure your attic is properly ventilated can prevent multiple costly problems and even lower your energy bills. If you have any concerns about your attic and its ventilation, have a qualified roofing contractor evaluate the attic and recommend a course of action.
