Insulation and Roof Vents
The combination of proper attic insulation and a well-functioning ventilation system is essential to keeping your home warm in the winter and cool in the summer. A poorly ventilated attic can allow a quarter of your heated or cooled air to escape through the roof and into unheated spaces in the house. An attic with inadequate insulation and no ventilation system can also lead to the formation of ice dams that cause expensive damage to your roof and home.
A roofing contractors vented attic allows outside air to flow into the attic space from soffit vents and then out through the gable or ridge vents. These vents need to be properly installed and adequately sized to function as designed. It’s also important to avoid covering soffit vents with insulation or other materials, as doing so can trap moisture and inhibit soffit ventilation.
How Insulation Reduces Noise and Creates a Quieter Home
Rafter vents are installed in your attic ceiling between the rafters to provide a channel for outside air to enter at the soffits and then up to the ridge vents where it can exit. They can be either static (which prevents precipitation from entering your attic) or powered to aid in air circulation.
Proper attic insulation, ideally with a high R-value, provides resistance to conductive heat flow that helps keep your home warmer in the winter and cooler in the summer. Minimum R-value requirements vary according to building codes and geographical areas. To maintain the effectiveness of your attic insulation and to prevent the loss of energy, it’s important to balance intake and exhaust ventilation in accordance with your local codes and standards.
