Most soffit designs don’t provide enough continuous NFA to work with roof exhaust requirements. This results in most homes not being properly ventilated; and roof manufactures won’t provide warranty coverage on homes without proper ventilation. Improper ventilation not only impacts the health and wellbeing of the homeowner but the health of the home. Without proper ventilation, warm attic air can become trapped and stagnate leading to moisture and the formation of ice dams in winter.
