The Importance of Soffit and Roof Ventilation

Proper Soffit Ventilation

As mentioned in our previous article regarding soffit replacement, it your soffits are damaged or if there is condensation in your roof the best option is always to fix the problem and replace the soffits.  However; it is possible that during one of your annual inspections you notice that no damage to your soffits or roof is present, but that your attic is constantly humid. In this case, soffit vents can be installed underneath the eaves of a roof for the purpose of ventilating your attic and roof.  Soffit vents reduce energy used on air conditioning as well as heating and more importantly extend the lifespan of your roof, soffits, and fascia.

Whether you live in a warm climate or a cold climate, proper roof and soffit ventilation plays a critical role in extending the lifespan of your roofing system.  Improper maintenance and care of soffits can prove a costly fix as it can damage the fascia, roof, and structural components of your home. Your local siding contractor can easily explain why proper attic ventilation is important, but in call cases it serves two main functions.

  1.      Allows fresh air to enter the attic at the soffited areas of the roof
  2.      Exhausts most air from the attic

Regardless of the climate, removing moist air and allowing the stagnant air in your attic to be replaced with fresh air is critical for a proper roofing system to function.

Benefits of proper soffit ventilation include:

  •        Reduce or eliminate damaging moisture from the structural components of your homes roof.  Excessive moisture can build up in stagnant air, potentially damaging the structure of your home and degrading both the roofing system as well as the soffits and fascia boards.
  •        Reduce energy costs associated with heating and cooling.  By eliminating heat and humidity buildup in an attic reduces the cost of a home to cool down the area closest to your roof.
  •        Prevents shingle damage including curling, cupping, and delamination.  Increased heat in an attic can cause shingles to prematurely age and lift off of the roof. Excessive heat or moisture in an attic can actually void many asphalt shingle warranties.

To properly maintain both your roofing system as well as your homes soffits and fascia boards proper ventilation is critical.  This ventilation creates a balanced system where the air is circulated and cooled eliminating many risks associated with hot and humid attics.  If your home is lacking intake or recirculation capabilities vents may need to be added to your soffits. Intake ventilation is critical to guarantee the air recirculates and your home stays healthy.
