The vents are the unsung heroes of your entire roofing system, playing a vital role in keeping the entire structure intact for as long as possible. Read on as roof repair contractor BSR explains everything you must know about the roof’s ventilation system and its importance.
Drawing Fresh Air in, Expelling Moist Air Out
A typical roofing system has intake and exhaust vents to facilitate air circulation and minimize heat and moisture buildup inside the attic. Intake vents, which are located at the eaves, draw fresh air into the attic. Exhaust vents, which are located at the highest points of the roof, expel the warm, rising attic air.
For roof ventilation to work properly, there must be a balance between air intake and exhaust. Roof repair and replacement specialists adhere to a specific requirement to ensure continuous attic air circulation. According to the U.S. Federal Housing Authority (FHA), a roof must have a minimum of one square foot of ventilation for every 300 square feet of attic floor space.
Why Are Roof Vents Important?
With proper design and installation, your roof’s ventilation system offers a wide range of benefits, such as the following:
- Reduced Moisture. Moisture buildup inside the attic can affect your roof’s wooden components, resulting in mold growth and rot. These, in turn, compromise the structural integrity and longevity of the entire system. These issues can be avoided with the right kind and amount of vents.
- Better Energy Efficiency. Excess attic heat tends to radiate down toward your home’s living spaces. By keeping this space well-ventilated, you ensure consistent indoor comfort and prevent your HVAC unit from working harder. This, in turn, lowers your home’s energy consumption, which will immediately reflect on your utility bills.
- Extended Roof Lifespan. Apart from the aforementioned mold and rot, the shingles and decking may also be at risk of deterioration because of excess heat and moisture inside the attic. By promoting air circulation, you preserve and even extend the service life of your roof.
