Attic Ventilation

Most people are unaware that attic ventilation can impact the longevity of their entire home. Proper attic ventilation is crucial for a long-lasting roofing system and Chicagoland Remodeling can help ensure your home investment is properly protected. What damage can occur with improper ventilation?

In the summer: an improperly ventilated attic can cause heat to build in excess of 150°F. This superheated air eventually penetrates the ceiling insulation into the living area below. Resulting damage: 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 also and higher cooling costs In the winter: various household appliances, bathtubs, showers, and cooking vapors can contribute to excess moisture build-up. Improperly ventilated attics will allow this moisture to collect and cling to the underside of the roof. This will condense and fall, soaking the attic insulation and reducing its efficiency. Resulting damage: Structural damage including roof deck warping and rotting of the wood frame, mildew growth and buckling of shingles and felt.

Ice Damming

Finally, attics should be properly ventilated to help prevent ice dams in cold winter 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 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.

Attic Ventilation Installation

We can install proper attic ventilation system that will allow for a continuous flow of outside air through the attic (see illustration) and will protect the efficiency of the insulation and help to balance temperatures in the living spaces. There are a variety of ventilation options available including ridge vents, power vents, louvers, turbines, mushroom vents and many more. A Chicagoland Remodeling professional can help choose the right one for your home.
