The proper roof installation transcends putting on the shingles. Regardless of the climatic conditions, proper attic ventilation is essential in making the roof last longer and prevent many expensive issues from taking place inside and outside the building. The kind of roofing experts and contractors that you use ought to explain the importance of proper attic ventilation. It plays two major roles. First, it allows cool and fresh air to enter the attic at the eave or soft areas of the roof. Secondly, it lets out hot, moist air from the attic through the ridge or other exhaust vents. The hot and moist air cam leads to many issues.
In areas where there is a cold climate, proper attic ventilation is essential in maintaining a cold roof system. It mixes the cool outside air with the attic air and allows for less snow melting on the roof. This prevents damaging ice damming. Proper attic ventilation in warm climates helps in venting out hot air because it can contribute to moisture problems. For your attic ventilation to work better, it must have balanced intakes and exhausts.
Achieving balanced ventilation
Balanced ventilation is achieved when both the intake and exhaust allow for an equal amount of airflow. This is because the natural forces of air pressure have a pull and push effect around the roof. If you do not have proper vents, the hot air will not escape. On the other hand, without proper intake, the air circulates across the top of the attic space. This leaves stagnant air at the bottom of the attic.
Circulation is also hindered when vents are only on one side of the attic. You would get the same effect when you open the windows on only one side of the house on a breezy day.

As such, you must ensure that the roofing allows for proper attic ventilation.
