Roof ventilation. Most homeowners don’t think about it. When a roofing problem or other indoor issue arises, the average homeowner does not consider the possibility of poor roof ventilation as a primary culprit or contributing factor. Ironically, roof ventilation plays a critical role in the overall health and well-being of the home and its occupants.

Without adequate roof or attic ventilation, indoor air quality is compromised. Consequently, poor air circulation often results in a house with numerous issues (such as mold and mildew growth, moisture intrusion, window condensation, allergen buildup, and unstable indoor temperatures). A homeowner should not overlook the value of sufficient roof ventilation.

What Is Residential Roofing Ventilation

Ventilation brings in fresh outside air and expels stale indoor air. This two-pronged approach offers numerous benefits to the home and its occupants. At the attic or roof level, ventilation is essential in removing rising warm air. Introducing clean air from the outdoors allows interior air to circulate freely.

When excess moisture accumulates in a dark interior space that lacks proper airflow, it produces the ideal environment for degradation. Unfortunately, the net result is a slow deterioration of roofing materials that destabilize a roof’s overall performance. Similarly, structural aspects of a home (including joists, rafters, trusses, and studs) experience an almost irreversible rotting effect due to pervasive exposure to moisture and high humidity levels. Eventually, the homeowner will need to perform extensive repair or replacement work.

We live in a world where environmental pollution is a harsh reality. Compared to previous generations, our air lacks purity. When a house has insufficient air circulation, it becomes an atmosphere where stale air, excess humidity, and unmitigated dampness trigger health problems (including asthma, itching, sneezing, allergies, and other physical conditions). In combating this growing problem, many homes have air purification systems. Ensuring adequate roof ventilation is another effective way to address air quality issues.

A home that does not breathe well means that indoor air has no viable means to escape. Since warm air rises, it often becomes trapped at the attic level, especially during hot summer months. When excess warm air remains inside a home, the cooling unit must kick into overdrive to offset the higher temperatures. Consequently, the homeowner consumes much more energy (resulting in a substantial increase in utility bills) than would otherwise be necessary with a proper ventilation system.

Nearly every home has a veritable means to control indoor temperatures using a thermostat. Many homes also possess a way to manage humidity levels in the house. However, responsibly overseeing the temperature & humidity depends on the home’s capacity to self-regulate, especially when a homeowner is away or unavailable. With the latest advances in technology, HVAC units have autopilot capabilities. Nevertheless, these automated apparatuses will underperform if external conditions (such as inadequate roofing ventilation) compromise their efficiency.

Radon gas is an odorless, colorless gas that has been linked to cancer. When a home lacks adequate ventilation, radon gas can become trapped in a home. Unfortunately, because radon gas is almost impossible to detect without specialized equipment, most homeowners may never realize they have been exposed until it is too late. Sufficient roof ventilation helps reduce radon gas concentrations, allergens, and irritants (as well as toxic volatile organic compounds (VOCs) emitted from household chemicals and furnishings).
