Poor Attic Ventilation Can Ruin Your Insulation, Destroy Your Shingles, and Raise Your Energy Bills! Why Take Risks?

ventilationIt is estimated that 9 out of 10 homes in North America do not have proper attic ventilation. Why? Because most people are unaware that attic ventilation in your Cleveland home can impact the longevity of their entire home!

For example, in the summer, an improperly ventilated attic can cause heat to build in excess of 160°F. This superheated air eventually penetrates the ceiling insulation into the living area below.

Types of damage that can result due to poor ventilation in your Cleveland home include:

  • Premature aging of your roofing system (“fried” shingles)
  • Warping, cracking, or breaking down of wood framing
  • Damage to siding, exterior or interior paint, and wallpaper
  • Higher energy costs

A properly ventilated attic can help reduce the load on your air conditioner by moving the superheated air out of your attic before it builds up and causes damage.

In the winter, various household appliances, bathtubs, showers, and cooking vapors can contribute to excess moisture build-up. Improper ventilation in your Cleveland home will allow this moisture to collect and cling to the underside of the roof. There, it will condense and fall, soaking the attic insulation and reducing its efficiency.

Additional structural damage caused by poor ventilation in your Cleveland home include:

  • Roof deck warping and rotting of the wood frame
  • Mildew growth
  • Buckling of shingles and felt

Finally, attics should be properly ventilated to help prevent ice dams in cold Northern climates. During the winter, ice and snow on a roof will melt and run down the deck to the cooler eaves. This run-off can re-freeze; creating an ice dam that will trap moisture on the roof. The moisture can eventually back up under the shingles and enter your home — causing hundreds or thousands of dollars of damage to your ceilings and walls. Adequate attic ventilation will reduce the amount of initial melting that occurs on your roof, thereby reducing the chance that ice dams will form.

Proper Attic Ventilation In Your Cleveland Home

Proper attic ventilation systems allow a continuous flow of outside air through the attic, protecting the efficiency of the insulation and helping to lower temperatures in the living space. It consists of a balance between air intake (at your eaves or soffits) and air exhaust (at or near your roof ridge).

The FHA (Federal Housing Administration) recommends a minimum of at least 1 square foot of attic ventilation (both intake and exhaust) for every 300 square feet of attic space. For example, if your attic is 900 square feet, you need a total of 3 square feet of ventilation. This amount is generally divided equally between intake and exhaust ventilation (i.e. 1 – 1/2 feet of each) to insure proper airflow through the attic.
