CHECK YOUR ATTIC TEMPS!
the temperature in your attic during a warm summer day with a
household thermometer. If it is 30 or 40 degrees above the
outside temperature, take action to lower the temperature. Focus
on attic ventilation. Make this simple calculation: Compute the
square footage of the attic floor by multiplying the width by
the length of your home. Divide the total square feet of floor
space by 300 if the attic has a vapor barrier or 150 if there is
no vapor barrier.
The resulting number of square feet is the total amount of open
area to the outside required to properly ventilate your attic.
Half should be high, as at a ridge vent, and half low from
soffit vents. If the home has gable end louvers, half should be
at each end of the home.
To improve attic ventilation, have a contractor install
additional venting. A power vent (attic fan) is recommended for
every house with a gable roof. The more fresh air moved
mechanically into the attic to replace the overheated air, the
cooler the attic and the lower air conditioning costs will be.
