What Homeowners Need to Know about Roofing Ventilation…
Among the many aspects of maintaining a roof in good repair, thus prolonging its life–especially in
the extreme climate changes of Loveland–is correct roof ventilation. It cannot be stressed enough how
a wellventilated roof will last for a longer period of time under intense weather conditions, such as
are experienced in Colorado. In Colorado’s freezing or subfreezing temperatures, good roof ventilation avoids unwanted
conditions like an ice dam. This condition arises when ice melts and refreezes along the borders of the
roof, causing a buildup of ice beneath the shingles. With good ventilation, heat collecting beneath the
roof cools and protects whatever snow is present from melting too soon.
At the opposite end of the weather spectrum, when the climate is hot and dry, appropriate roof
ventilation preserves energy necessary for your air conditioning system to operate efficiently. In this
instance, good ventilation helps to lower heat gathering in your attic. As a result, the energy burden is
lifted from your HVAC systems, prolonging their life.
Another culprit undermining the integrity of your roof is moisture. A sound ventilation system will
force out moisture below the roof deck, and if not installed can cause all manner of problems, from
rusted, fragile nails to mold or fungi growth to roof rot.
In searching for a ventilation system, you want one providing more than just limited protection. With
partial ventilation you run the risk of experiencing all the conditions described earlier. The most
beneficial results can be obtained with ventilation focusing on all the critical areas of your roofing
infrastructure. This way you purge irregularities compromising your roof’s life span.
Now you have read our primer on how a complete ventilation system will save you energy costs, and
also a too-soon failing roof, you will be ahead of the game when you speak with a ventilation professional.
