Whenever Possible Penfolds Roofing will recommend upgrading the roof ventilation system because in doing so it will:

• Provide our customers with a more comfortable home.
• Keep attics cool and consequently reduces heat that build that enters the home during winter months.
• Reduce moisture to keep attics dry during the colder months and help prevent ice dams.
• Increase the life of the roof and meet or exceed the specifications of roofing shingle manufacturers.

Most important is that the ventilation system be balanced to provide an even intake at the soffit with that of the ridge.

These sketches demonstrate the principles in both the warmer and the cooler months including the balanced ventilation principle.

There is a specific formula to calculate the actual amount of ventilation required. This is different for all homes.

All Penfolds Technical Advisors are well trained to advise you in making the right decision for your home.
