Roof Ventilation: An Introduction to Its Benefits

A well-rounded, adequate ventilation system is one of the hallmarks of a good roof, which consists of a logical system of intake and exhaust vents. Without these vents, your roof will have no proper airflow underneath it, which regulates its temperature whatever the season.

In today’s post, your roof replacement contractor, Home Pro Exteriors, Inc., discusses the benefits of proper roof ventilation.

Prolongs Shingle Life

Without sufficient airflow, your shingles may be cooked from underneath, leading to shingle curling and blistering. When this happens, the protective asphalt granules may deteriorate rapidly, which means your roof will fail prematurely.

So how does this happen? Without exhaust vents, warm air (which naturally rises) will be trapped underneath your roof, which will wear the roofing supports from the inside. Pair this with being battered from the outside by direct sunlight and you’d see how ventilation is simply mandatory.

Prevents Ice Dams

Any roofing contractor knows that without ventilation, the warm air that pools up in your attic creates a temperature differential between the parts of your roof. The topmost parts will be warmer, while the lower you go, it will be colder. This means that in winter, snow will melt from the top of the roof, which, due to gravity and the slope of the roof, will trickle down to the lowermost parts. But because these parts, including the eaves, are colder, the snowmelt will refreeze, causing ice dams and clogging your gutters—thus creating a leak risk.

Prohibits Mold and Mildew Growth

Mold and mildew naturally love any moist environment and an attic without ventilation is one. Warm air carries more water vapor than colder air, so when it’s trapped in the attic or the underside of your roof, the moisture will seep into the wooden structure. Over time, the excess moisture will attract mold and mildew, which can cause respiratory problems for anyone in the home.
