Why Take Risks?
It 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
can impact the longevity of their entire home!
An improperly ventilated attic can cause heat to build above
160°F. This superheated air creates downward pressures that penetrate the ceiling insulation into the living
Types of damage that can result 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.
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. There, it will condense on nails, accelerating their failure and drip onto the attic insulation, reducing its
Additional structural damage can include:
Roof deck warping and rotting of the wood frame
Buckling of shingles and felt
Roofs 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.
