How does attic ventilation work?

     Proper Attic ventilation includes intake vents pulling air in at  your soffits (soffit vents) and exhaust vents releasing warm humid air high up in your roof. Exhaust vents include ridge vent, attic vents, and solar fans. Baffles are protective columns that are installed inside the attic along the roof boards down at the soffit. They protect the air flow from being hindered by insulation and debris and help channel the air up along the roof decks. 

     Soffit vents, baffles, solar fans, and exhaust vents work together to allow proper airflow in your attic. When installed correctly, fresh air is allowed to enter the attic, cooling and drying off roof boards, preserving the life of your roof, preventing moisture build up in the winter, and keeping your attic and home cool in the hot summer months. Our Attic Experts can inspect your attic’s current ventilation, assess any needs, and provide you with a detailed evaluation of how our attic ventilation services can improve your home’s ventilation system.

Why is adequate attic ventilation important?

     In the summer, heat radiates on your home and attics can reach temperatures up to 130 degrees or higher. At these temperatures your shingles will begin to buckle and curl. Without proper ventilation attics can easily reach 130 degrees or hotter. At these temperatures, living spaces below can become unbearable. 

     In the winter, warm air rises into the attic from the heated living space and warms the roof deck, prematurely melting the snow. This water runs down the roof and freezes along the cooler outer edge. As this process continues, the ice builds up blocking the run off, and the water backs up under the shingles, creating significant damage and costly repairs. 

     Without proper ventilation, humidity from your home can become trapped in your attic. Once it reaches the cooler attic air, it condenses. This moisture not only creates a breeding ground for mold and mildew, it can ruin attic insulation and deteriorate the internal structure of your roof.

Signs of poor attic ventilation:

• An unexplained increase in your heating and cooling bills, which can occur from damaged insulation. 

• Frequent HVAC repair or premature failure due to increased workload and wear

• Ice Dams forming along your roofline or obvious snowmelt on the upper portion of your roof

• Wavy or rippled appearance to your roof line and shingles caused from moisture damaged decking

• Rust or corrosion on metal materials in your attic such as nails, electrical boxes, etc

• Mold, mildew, or water stains on roof sheathing.

• An increase in allergy symptoms or respiratory illnesses which may be related to the spread of fungi spores from mold growth in your attic.

How can you increase your attic ventilation?

1. Increase the number of Soffit Vents

2. Install Baffles between every truss

3. Install a Solar Fan

4. Increase the number of vents on your roof
