EXTEND THE LIFE OF YOUR ROOF WITH A BALANCED VENTILATION SYSTEM

How does it work?

Hot air rises to the peak of the attic and with a proper ventilation system that is balanced, it allows for equal amounts of air intake and air exhaust. This is important as the continuous ventilation releases the hot moist air that gets trapped in the attic.

How does a proper ventilation system benefit the client?

  • Reduces heating and cooling costs
  • Eliminates heat build-up in the summer, moisture build-up in the winter and ice dams in climates with snow and ice
  • Eliminates poor indoor air quality
  • Helps to prevent damaging mildew and mold build-up
  • Increases the life of roof shingles
  • Helps improve the comfort level inside the home

How visible is a ventilation system?

For decades, ventilation systems have been evolving and becoming less visible.

Currently, there are a variety of ventilation systems that are virtually invisible, which makes for a far more attractive roof.

 

For the most accurate air circulation, 50% of the vent area should be in the roof and the remaining 50% should be in the soffit (intake).

How much ventilation does my roof require?

The minimum requirement to ventilate a home is 1 sq. ft. of ventilation for every 300 sq. ft.

If you have less than 2/12 pitch, then it is 1 sq. ft. for every 150 sq. ft.

Ventilation required is calculated based on the square footage of the attic floor.
