Why Is Proper Roof Ventilation So Important?

attic-ventProper attic ventilation provides benefits all year–round by creating drier attics in the winter and cooler attics in the summer. In fact, it enhances the efficiency of the heating and cooling system. Homeowners whose utility bills continue to grow each month should consider checking their roofing ventilation. Proper attic ventilation is important, especially for residents of Dallas, TX, a hot and humid region that experiences summer highs of about 102 degrees Fahrenheit. Unfortunately, many homeowners in the area do not understand the importance of a well–ventilated attic.

Roofing ventilation uses a system of intake and exhaust vents to create a flow of air. The exhaust vents let out hot air while the intake vents let in cooler air to replace the hot air. Usually, the cooler air is under the overhangs; therefore, homeowners should place the intake vents in the soffit. To achieve proper ventilation, homeowners should install one square foot of ventilation per 150 square feet of attic space.

In addition to lowering the cooling costs, sound roofing ventilation protects the structural integrity of the roof by releasing moisture that may otherwise collect and cause damage. Moisture can cause any metallic material including nails to rust and even break. In addition, the roof deck itself can deteriorate from dry rot and various types of fungi and mold can develop due to excess moisture.

Signs of Poor Attic Ventilation

  • Mold growth
  • Frost on rafters, sheathing or other items in the attic
  • Massive buildup of heat in the attic
  • Water dripping from the tips of nails
  • High cooling costs
  • Premature aging of the roofing system
  • Damage to siding, interior paint and wallpaper

Homeowners experiencing such issues should hire a qualified roofing contractor to evaluate their roof. Roofing ventilation offers its fair share of advantages of which every homeowner should be aware. A Well–laid roofing system is much more than well–installed shingles; proper protection of the system is of significant value to the homeowner.
