As mentioned before, heat enters the attic easily without proper ventilation. Roof vents allow the hot air to escape, preventing your roof’s surface and your attic from overheating. When roofing materials are exposed to excessive sunlight, this expedites the degradation process. Hot weather deteriorates roof shingles, and as they split and crack under intense heat, areas of the underlayment are exposed to direct sunlight.
While your roofing materials rot, heat enters the home through the attic. As your house gets hotter, you turn up your AC to cool it down—but it’s no use if there’s inadequate ventilation, and the temperature inside will continue to rise. However, with roof vents, air flows through the attic and lowers the temperature. When your home is naturally cooler, you enjoy reduced energy bills.
