Introduction

This video explains the importance of proper roof ventilation and how to determine if your roof has adequate ventilation. It discusses different types of vents (box vents, gable vents, ridge vents, soffit vents), how to calculate ventilation needs using the Owens Corning calculator, and how to fix common ventilation problems, such as mixing different types of exhaust vents.

Key Takeaways

• Adequate exhaust ventilation is crucial for roof health. Insufficient ventilation can lead to problems.
• Use the Owens Corning ventilation calculator to determine the necessary square inches of exhaust ventilation based on attic size.
• Avoid mixing different types of exhaust ventilation systems. This can disrupt airflow and reduce efficiency. Mixing intake and exhaust can lead to improper ventilation.
• If mixing exhaust systems, use insulation to block unwanted airflow. This is a temporary solution, preferably replaced with a proper ridge vent system during a roof replacement.
• Replacing box vents with a ridge vent is a better solution. This provides more effective and balanced ventilation.
