Exhaust Roof Ventilation

Exhaust ventilation is a key component to both the performance and longevity of a home/ building and its roof system. Without the outflow of warm moist air from the attic/ roof space, there will be no way for cooler dry air to re-enter.

Excessive heat and moisture in the attic/ roof space and lead to a faster degredation of the roof deck, nail pops, buckled sheathing and shorten the lifespan of the roofing materials especially asphalt shingles.

Exhaust ventilation must work in junction with intake ventilation to create what is called passive airflow. Passive airflow is the cycle in which warm moist air leaves the attic space and fresh cooler air enters. This helps regulate the temperature of the roof/ attic space with the temperature outside preventing heat build up and condensation.

Condensation in the attic space will lead to mold and mildew. A well regulated attic/ roof space temperature will help cut back on AC costs and help insure a higher quality air in the home. Inadequate roof/ attic ventilation will ultimtely effect roofing product warranties and even warranties from the company who installs the products.
