The Importance of Proper Attic Ventilation

There are many services that roofing contractors can provide to maintain your roof and protect your home throughout the harshest summer and winter seasons.  Attic ventilation services is one of the most important jobs that a roof repair contractor can offer.

During the summer months in the Midwest, an improperly ventilated attic can cause heat to build to temperatures in excess of 160°F!  This excessive heat creates downward pressures which penetrate the ceiling insulation and migrate into your living area below.  Moreover, You also cannot have a valid manufacturer’s warranty on your shingles without proper ventilation.  As such, not only will improper ventilation reduce the lifespan of your roof, it will also void your manufacturer’s warranty, and rest assured that shingle manufacturer’s will send an inspector to determine this should your roof need replacement under a warranty claim.

A correct attic ventilation system provides for a steady flow of outside air from the lowest part of the attic through the upper most part of the attic. As shown in the illustration, proper attic ventilation allows the attic insulation to perform at peak efficiency and help maintain constant temperatures in your home."Proper Attic Ventilation"

There are many roof ventilation styles available on the market. Choosing the right style for your home is critical to providing optimum air flow and function.

It is estimated that 9 out of 10 homes in North America do not have proper attic ventilation. Because most people are unaware that attic ventilation significantly impacts the longevity of their entire home, many roofs continue to become degraded and damaged.  Some of the common types of damage caused by improper attic ventilation include:

  • Premature aging of your roofing system
  • Roof deck warping and rotting of the wood frame
  • Buckling of shingles and felt
  • Mildew growth
