Some homeowners do not understand the importance of roof ventilation systems when it comes to extending the lifespan of a roof system. When the proper amount of intake and exhaust vents are installed, your roof lasts longer. The opposite is true if your roof ventilation is not up to the job.
If your home does not have the right amount of attic ventilation, hot air becomes trapped, causing all types of avoidable problems.
How Much Ventilation Should You Have?
Every home needs a ventilation system that works to circulate air and reduce moisture levels in the attic. Just as you need to assess the size of your furnace and air conditioning systems to make sure they cover the entire home, you will need to have the right amount of attic ventilation for your roof.
The FHA recommends at least 1 square foot of ventilation for every 300 square feet of attic space. Position the intake vents strategically positioned above the eave, also known as the soffit. While the exhaust vents should be installed close to the roof’s peaks.
Too Much Ventilation Is Not a Good Thing
While vents are necessary, too many leave you more vulnerable to leaks, can cause a blow out during a hurricane or worse. The amount of vents you need will also vary depending on the roof’s slope and size of the attic space. It is best to consult with an experienced professional.
7 Signs Your Roof Ventilation Is Not up to the Job
- Moisture Buildup affects your insulation and encourages mold growth
- Insulation is Flattened or Clumping
- Black Mold Growth can damage the beams, rafters or ceiling joints
- Rust forms where beams or boards intersect by trapped moisture lingering in your roof space
- Ice Damming which can cause shingle loss, load bearing issues and leaks
- Ice cycles hanging along the eaves and gutters
- High Energy Bills
