Attic Ventilation

The wrong approach to attic ventilation can cause serious problems in your attic, and you may never know it until it’s too late.

Serious problems in attic

Ventilation is one of the most important elements of your attic and roof design.

Ventilation is much more than a simple breeze blowing through your house; it’s a process that provides a steady, high volume of air movement. Proper ventilation requires an entire system of components, expertly designed to provide constant intake and exhaust of air.

Shingle manufacturers require proper attic ventilation in order for their shingle warranty to be valid.

You may not realize that shingles are made of an oil-based material. On a 90-degree day, an attic can reach up to 150 degrees. This super heating of the shingles dries their oils and causes the loss of the small stones, or granules, embedded in the asphalt to protect the shingles from UV-rays.

Once these stones come off, the asphalt is exposed to powerful UV rays, and the shingles will fail.

Installing proper attic ventilation:

  • Reduces heat build up during the summer and saves you money by reducing your air conditioning use
  • When the overhang or soffits are properly venting, the roof vents draw air from the outside of the home rather than the interior living space, reducing energy costs in the winter
  • Eliminates moisture that leads to black mold, mildew and wood rot
  • Protects against the development of ice dams in winter
  • Extends the life of your shingles
  • Helps prevent premature roof failure
  • Protects the “R” value of your insulation

According to experts, ridge venting, along with balanced soffit ventilation, is the best solution for most homes, and the method recommended by quality shingle manufacturers.

Ridge venting is most effective when the ridge of your home is long enough to provide the correct amount of exhaust venting.
