Ventilation Problem With A...
Fascia
Intake Vent
Many homes in North America have inadequate attic
ventilation systems. Inadequate attic ventilation can often
be attributed to homes having little or no intake ventilation.
Failing to properly install intake ventilation can render
your attic ventilation system virtually useless.
Efficient attic ventilation systems are similar to the human
body. Intake ventilation lets cool, fresh air into the system,
similar to the body inhaling. Exhaust ventilation (commonly
ridge vents) allows moist, warm air to exhaust from the
system, similar to the body exhaling.
Cape Cod-style homes with no soffits, mansard roofs, or even
vented roof deck systems are extremely challenging to properly
ventilate, especially with intake ventilation. To make matters
worse, homes with existing soffit or undereave vents can have
ineffective intake ventilation because their vents have become
clogged with dirt or have been painted over.
Cobra FasciaFlow® Premium Intake Ventilation is a key p
­ art
of the GAF Lifetime Roofing System and has even earned
the prestigious Good Housekeeping Seal (see back page).
