• Lowers Attic Temperature -   Attic temperatures can exceed 160°F on hot summer days.  Proper attic ventilation can reduce those temperatures by up to 50°F. No
    matter how much insulation is in the attic, heat can still transfer into adjacent  living spaces.  In fact, extra insulation can actually add to temperature increases
    because heat is trapped in the insulation. Proper ventilation evacuates this excess heat build-up.

  • Reduces AC Load -  Fan lowers attic temperature reducing the load on the HVAC System.  Heat is exhausted, saving energy and extending the life of the air
    conditioning system.

  • Extends the life of the roofing materials - Though asphalt shingles are designed to take the abuse of the sun for many years, they are subjected to greater
    temperatures when the roof decking is allowed to overheat, which is just what happens in an under ventilated attic.  Asphalt shingle manufacturers warranties
    require proper attic ventilation.  Attic ventilation is required in cold environments - it evacuates the warm moist air that heat sources produce. Hot moist air lingering in
    the attic spaces can condense on the underside of the roof sheathing and rot it out and also causes mold to develop on the interior walls.

  • Reduces Moisture Damage - During cooler months, moisture is the most serious concern. Even with the use of vapor barriers to keep moisture from entering the
    attic, air leaks around ceiling light fixtures, bathroom exhaust fans allow  unwanted moisture into the attic. Moisture condensing on the framing members and the inside
    of the roof deck can lead to the growth of mold, mildew and rot in the roof deck and framing. A good indicator of moisture problem is rusty roof nails sticking through
    the roof deck.            

  • Maintains Comfortable Temperature in Adjacent Living Spaces -  Cooler air in the attic space will not affect the temperature in the adjacent living spaces if
    properly insulated.

  • Prevents Ice Dams - Good ventilation helps prevent ice dams, which begin to form when warm air in the attic melts the snow from beneath and creates runoff that  
    refreezes on the colder eaves.
