The following
article appeared in the Milwaukee Journal Sentinel. Great
roof venting is not a required code item. This article shows
what we at Miracle Homes have stressed to our clients. When
building a new home, we suggest continuous (not square mushroom
style) roof venting on both the roof peak and at each and
every roof truss space. That means soffit vents every 24 inches,
not every 48 as is normal.

A well-vented attic insulates your wallet
By Edward
R. Lipinski
New York Times News Service
Good attic
ventilation is important because it helps to dissipate excess
heat in the summer, making it easier to cool the house and
lowering energy costs.
In the
winter, a well-ventilated attic expels water vapor that would
otherwise condense in the insulation. Proper ventilation also
maintains a cold roof in the winter and prevents the formation
of troublesome ice dams.
Unfortunately,
the value of good attic ventilation has been recognized only
within the last few years, so most homes, even relatively
new ones, may not have good ventilation.
Most homeowners
assume that a few vents through the roof will be enough to
keep the air circulating, but these may not be enough.
To tell
if your attic is ventilated properly, first look for these
signs: In the summer, hot air and high temperatures in the
attic are indications that the air is stagnating and the space
needs to be vented. Hold your hand near the vents. You may
actually be able to feel a slight breeze - an indication that
the vents are pulling air outside. In the winter, look carefully
to see if moisture is condensing on the framing members or
on the insulation. This will happen when the attic temperature
is low and there is little air
