GAF® Materials Corporation Ventilation

If you want your roof to last a long time then you need to make sure it's ventilated properly. Proper ventilation can protect against moisture and heat build-up, by allowing them to be released through your roof. Proper ventilation can also protect against the dangers of the seasons, like ice dams that can build during harsh winters and against the hot and humid summer months.




When you attic's ventilation system is correctly balanced your roof will be protected against:

  • Premature deterioration by removing excess heat and moisture.
  • Preventing rot in your roof deck and/or attic.
  • Extend the life of your interior and exterior paint by minimizing peeling.
  • Protects your attic against mildew.
  • Protects against ice dams during harsh winters.
  • Possibly could reduce heating and cooling costs.
