Although it may not seem like a major
consideration, attic ventilation, when
properly installed, can provide the
homeowner with the significant advantage
of extending the life of an attic & roof
structure, saving considerable repair
costs over time.
During warmer months,
ventilation:
-
Helps keep attics cool
-
Helps prevent hot, moist summer
air from warping the roof sheathing
-
Stops shingles from
deteriorating prematurely
-
Allows for fresh air in the
attic, making a home much easier to
cool, which can result in lower
energy costs
During winter months,
ventilation:
-
Helps reduce moisture to keep
attics dry
-
Stops water from backing up
under shingles, damaging insulation,
and rotting the roof structure
itself
-
Prevents ice dams from forming
In the latter case, ice dams occur in
areas where snowfall and cold
temperatures typically exist. Ice
dams are a problem because they prevent
melt water from running off the roof,
and can sometimes cause leaks, and thus
damage, inside your home. To learn

them, view the Interactive

What is attic ventilation?
Intake and Exhaust
 For
your home, it's the movement of hot air
out, cooler air in. The
ventilation of your attic space allows
for this air flow, allowing new fresh
air to come in to replace the older
stale, overheated air. This is
called "air exchange."
Although it may seem like a simple
process with low air
movement, ventilation of your attic
space is much more - it's a mechanism
that allows for steady, high volume
movements of air in and out of your
attic, the constant intake and exhaust
of air.
