Why Proper Roof Ventilation is Crucial for Your Home

You might not give your roof much thought unless it’s leaking or covered in snow, but it plays a vital role in protecting your home. One often overlooked aspect of roof maintenance is proper roof ventilation. It might sound technical, but understanding its importance can save you significant headaches and money down the line.

What is Roof Ventilation?

Roof ventilation is a system of intake and exhaust vents that allows air to flow through your attic. This airflow helps regulate temperature and moisture levels, preventing damage to your roof and home.

Why Does it Matter?

• Protects Your Roof:
  • Prevents Heat Buildup: In summer, the sun’s heat can turn your attic into an oven. Proper ventilation allows hot air to escape, preventing shingles from deteriorating, cracking, or curling.
  • Reduces Moisture: Moisture is the enemy of roofs. Ventilation helps remove excess moisture, preventing mold, mildew, and rot. This is especially important in humid climates.
  • Ice Dam Prevention: In winter, proper ventilation can help prevent ice dams by keeping the roof deck colder, reducing the chances of snow melting and refreezing.
• Improves Indoor Comfort:
  • Energy Efficiency: A well-ventilated attic helps insulate your home, reducing energy consumption for heating and cooling.
  • Better Air Quality: Proper ventilation helps prevent the buildup of allergens and pollutants in your attic, improving indoor air quality.
• Increases Home Value:
  • A well-maintained roof with proper ventilation is a significant selling point when it comes time to sell your home.

Signs of Inadequate Ventilation

If you suspect your roof might not be ventilating properly, look for these signs:

• Ice dams in winter
• Shingle damage or premature aging
• Mold or mildew growth in the attic
• Excessive heat buildup in the attic
• High energy bills

Remember: Proper roof ventilation is an investment in the long-term health and value of your home. Don’t ignore the importance of this often-overlooked component of your roof. Additionally, too much exhaust ventilation will cause substantial increases in your energy bill! If your roofer has told you they are installing “ridge vent”, then they are installing too much exhaust ventilation for your attic space and you will see the dire outcome each month with substantial increases in your energy bill! The reason most roofing sales companies include installing ridge vent is because they do not know the IRC building code requirements for ventilation, and are incapable of figuring the net free air required for intake and/or exhaust ventilation, so they slap on ridge vent and “hope” it works.
