Ventilation Systems:                                      

Attic ventilation is an important part of your home’s design and construction.

• In the summer attic ventilation can help prevent heat buildup, which will help make your living
areas cooler and more comfortable, help reduce air conditioning costs and help prevent premature
roof shingle deterioration. The major shingle manufacturers require attic ventilation to validate the
shingle warranty.

• In the winter attic ventilation can help prevent moisture buildup, which will help prevent wood
rot, mold, mildew and poor indoor air quality. And because it helps keep the roof deck uniformly cool in the winter, attic ventilation (along with proper attic insulation) can help prevent the uneven freeze/thaw cycle associated with snow on your roof that often leads to ice dams which can backup water under shingles causing roof deck and interior sheathing damage.

The average family of 4 generates 2 to 4 gallons of water vapor through activities such as bathing, cooking , cleaning, showering, laundry and breathing.

Some of this water vapor rises into your attic. Ventilation helps remove it before it causes problems such as wood rot, wet insulation, mold and mildew.
