Your roof is more than the shingles you see from the street.
On a vented attic system, outside air enters through intake vents near the eaves and moves upward before exiting through exhaust ventilation near the roof peak. Balanced intake and exhaust help manage heat and moisture and support the roofing system as a whole.
Ventilation can also matter when it comes to roofing-product installation requirements and warranty coverage, which is why it should be evaluated as part of the complete system rather than treated as an afterthought.
The shingles are one component. The ventilation, insulation, decking, flashing, and other components all have to work together.
Your roof is a system.
