Let Your Attic Breathe For The Health Of Your Home

Many homeowners overlook their attic space and think its purpose is extra storage or a scary place they don’t want to venture to. In all reality, your attic is a vital part of your home’s blueprint that if neglected can cause increased energy bills, premature shingle decay, poor air quality and damage to your insulation.

In the summer months, when the sun hits the roof of your home, heat penetrates your attic. If you have improper ventilation in your attic, the heat is forced down into your home which causes your appliances such as fans, refrigerators and air conditioners to work harder, increasing your energy efficiency and energy bill.

Having proper ventilation in winter months is just as important due to the moisture that snowfall brings. A family of four you generates two to four gallons of water vapor during your daily activities, which rises in your home to your attic area. This rising vapor condensation can cause your insulation to become damp causing wood rot, mold and mildew to be circulated in your air quality throughout your home.

Inadequate ventilation in your home can also affect the exterior. Areas on your roof can become warmed causing snow melt and the formation of ice dams. Ice dams are when the melted snow on your roof flows down until it hits a colder spot, where it refreezes and causes a back-up of ice on the roof.

Heat build-up and excessive moisture can cause your roof decking and shingles to deteriorate prematurely. Proper ventilation will ensure consistent surface temperatures on your roof eliminating moisture damage to your roof.

You want to achieve a balanced ventilation system in your home where intake ventilation at the eaves is equal to that at or near the attic ridge area. Accomplishing this will help reduce energy costs for your home and decrease the change of damage.

When having ventilation systems installed make sure to check:

  • That the intake vents are not covered with insulation or painted closed
  • That attic insulation baffles are inserted into the soffit of the intake vents
  • That the same exhaust vents are used throughout your attic and roof
