Roof Ventilation

Proper ventilation will result in drier attics in the winter, cooler attics in the summer, and help reduce energy consumption.  Without proper roof ventilation, common household activities can wreak havoc on a roof or attic:

  • In Hot weather heat can transfer back down into living areas – reducing energy efficiency
  • In cold weather, warm air generated by laundry, showers, cooking, or dishwasher can linger in the house and cause moisture build-up.

In fact, ventilation deficiencies are the most common flaw that may void manufacturer warranties.  Proper ventilation and attic insulation help maintain a comfortable temperature inside your home, increase energy efficiency, prevent moisture damage, and maintain the longevity of a roof.

 

Common Roofing Ventilation Mistakes:

  • Attic insulation is blocking the intake vents
  • Bathroom vents are exhausting into the attic
  • Insufficient air flow or too few vents
  • Mixed exhaust ventilation used on the same roof
  • Covering turbine vents in the winter

 

For roof vents to work well there must be a source of replenishment air.  Intake Vents provide a source of fresh air and are usually located in the eaves or soffits. Exhaust Vents allow fresh air to leave the attic, and are located on or near the ridge line of the roof.

In most cases, exhaust ventilation should never be mixed on the same roof.  For example if a ridge vent is used with a power vent, it will start to act as an intake vent allowing rain or snow to infiltrate your attic. Our experienced project managers can recommend the right ventilation for your home.
