Roof ventilation
plays an important
role in the health of your home

A properly ventilated attic or crawlspace helps ensure the longevity of roofing materials. It also prevents the growth of mildews, and can even save you money on energy bills. Good air flow may be obstructed by a variety of factors that require knowledgeable inspections to locate and to repair. Once a roof is replaced, A.J. Wells Roofing & Construction will ensure proper roof ventilation.


The Advantages of
Proper Roof Ventilation

  • Normalized temperatures within the home. Poor ventilation can lead to trapped heat in the attic or crawlspace, which can increase the costs of air conditioning a home.
  • Longer roof life. Proper ventilation ensures your roof has the best conditions for the components/materials that make the roofing system. Many shingle manufacturers require proper ventilation to honor their warranty.
  • Decreased humidity. A poorly ventilated attic can trap moisture, which then cannot dissipate. This may cause mold, mildew, and may damage wood or insulation. Good air flow removes trapped humidity.

The Causes of Poor Ventilation

Troubles with a roof’s ventilation may not be apparent to the untrained eye. It is important to have a professional evaluate the condition of roof or attic ventilation. Causes may include:

  • Vent blockage by felt paper or insulation materials.
  • Improper installation of vents over solid wood.
  • Improper size and locations of vents based on roof geometry.
  • Vents placed over incorrectly sized holes.
  • Multiple vent types that do not match roof geometry.
